Description

Technical Field

[0001] This application relates to the field of data processing technology, and in particular to environmental monitoring methods, apparatus and computer-readable storage media. Background Technology

[0002] In recent years, the large-scale development and deployment of wind farms have increased surface roughness and friction in ecosystems, affecting boundary layer turbulence and potentially altering the intensity and patterns of material, energy, and moisture exchange between the land surface and near-surface atmosphere, thus impacting atmospheric circulation and climate. Therefore, monitoring the impact of wind farms on the ecoclimatic environment of ecosystems is particularly necessary.

[0003] In existing solutions, the ecological and climatic environment of an ecosystem can be monitored using environmental monitoring equipment. When deploying environmental monitoring equipment, the locations of monitoring points are usually determined manually based on experience, and the equipment is then deployed at these locations. Due to the uncertainty of human experience, the accuracy of determining the location and number of monitoring points is low, resulting in low efficiency of environmental monitoring. Summary of the Invention

[0004] This application provides an environmental monitoring method, apparatus, and computer-readable storage medium, which can improve the accuracy of determining environmental monitoring locations and increase the efficiency of environmental monitoring.

[0005] To achieve the above objectives, this application adopts the following technical solution:

[0006] Firstly, an environmental monitoring method is provided, comprising: acquiring environmental monitoring data of each of multiple first environmental monitoring points in a target area within a preset time period; a wind farm is located in the target area, the target area includes multiple first sub-regions, the ecological environment of each first sub-region is affected by the wind farm to a different degree, the number of first environmental monitoring points in a first sub-region is positively correlated with the degree of impact of the wind farm on the first sub-region, each first sub-region includes multiple second sub-regions, the ecological degradation of each second sub-region is different, the number of first environmental monitoring points in a second sub-region is positively correlated with the degree of ecological degradation of the second sub-region; and selecting multiple environmental monitoring points from multiple first environmental monitoring points in each second sub-region of the target area according to a preset selection ratio. A set of second environmental monitoring points; the second environmental monitoring point set includes multiple second environmental monitoring points, each second environmental monitoring point set includes different multiple second environmental monitoring points, and the preset selection ratio is less than 1; determine the target environmental monitoring point set among the multiple second environmental monitoring point sets, and use the multiple second environmental monitoring points included in the target environmental monitoring point set as the target environmental monitoring points of the target area; the target parameter of the target environmental monitoring point set is the minimum value among the target parameters of the multiple second environmental monitoring point sets, the target parameter is the absolute value of the difference between the statistical parameter corresponding to the second environmental monitoring point set and the statistical parameter corresponding to the multiple first environmental monitoring points in the target area, and the statistical parameter is either the mean or the variance of the environmental monitoring data.

[0007] Based on this scheme, environmental monitoring data from multiple first environmental monitoring points in the second sub-regions of different first sub-regions within the target area are acquired. Following a preset selection ratio, multiple sets of second environmental monitoring points are determined from these first environmental monitoring points. Subsequently, a target environmental monitoring point set is determined from these second environmental monitoring point sets. The multiple second environmental monitoring points included in the target environmental monitoring point set are then used as the target environmental monitoring points for the target area. Since the ecological environment of each first sub-region is affected by wind farms to varying degrees, and the degree of ecological degradation varies in each second sub-region, the number of first environmental monitoring points within a second sub-region is positively correlated with the degree of ecological degradation in that sub-region. The statistical parameters corresponding to the target environmental monitoring point set are closest to the statistical parameters corresponding to the multiple first environmental monitoring points within the target area. Therefore, suitable target environmental monitoring points can be determined based on the different impacts of wind farms and the different ecological conditions, thereby improving the accuracy of environmental monitoring point determination and increasing the efficiency of environmental monitoring.

[0012] In conjunction with the first aspect, in some embodiments of the first aspect, obtaining environmental monitoring data of each of the multiple first environmental monitoring points in a target area within a preset time period includes: obtaining initial environmental monitoring data of each of the multiple first environmental monitoring points in the target area within a preset time period; and for each of the multiple initial environmental monitoring data, interpolating the missing values ​​in the initial environmental monitoring data to obtain environmental monitoring data.

[0033] In this application, unless otherwise specified, the same or similar parts between the various embodiments can be referred to each other. In the various embodiments and implementation methods of the various embodiments in this application, unless otherwise specified or logically conflicting, the terminology and / or descriptions between different embodiments and between the implementation methods of the various embodiments are consistent and can be mutually referenced. The technical features in different embodiments and between the implementation methods of the various embodiments can be combined according to their inherent logical relationships to form new embodiments, implementation methods, implementation methods, or implementation approaches. The following embodiments of this application do not constitute a limitation on the scope of protection of this application.

[0034] In recent years, the large-scale development and deployment of wind farms have increased surface roughness and friction in ecosystems, affecting boundary layer turbulence and potentially altering the intensity and patterns of material, energy, and moisture exchange between the land surface and near-surface atmosphere, thus impacting atmospheric circulation and climate. Therefore, monitoring the impact of wind farms on the ecoclimatic environment of ecosystems is particularly necessary.

[0035] For example, plateau ecosystems are often affected by global climate change and wind farms, leading to ecological problems such as grassland degradation, desertification, and loss of biodiversity, resulting in instability. Meanwhile, the abundant wind resources on plateaus have led to a gradual increase in the number of wind farms, which are having an increasingly significant impact on the plateau's ecological and climatic environment.

[0036] In existing solutions, the ecological and climatic environment of an ecosystem can be monitored using environmental monitoring equipment. When deploying environmental monitoring equipment, the locations of monitoring points are usually determined manually based on experience, and the equipment is then deployed at these locations. Due to the uncertainty of human experience, the accuracy of determining the location and number of monitoring points is low, resulting in low efficiency of environmental monitoring.

[0037] Figure 1 This is a schematic diagram of the architecture of an environmental monitoring system provided in this application. The technical solutions of the embodiments of this application can be applied to... Figure 1 The environmental monitoring system shown is as follows: Figure 1 As shown, the environmental monitoring system 10 includes an environmental monitoring device 11 and an electronic device 12.

[0038] The environmental monitoring device 11 is directly or indirectly connected to the electronic device 12. This connection can be wired or wireless, and this application embodiment does not limit the connection.

[0039] The environmental monitoring device 11 and the electronic device 12 can exchange data.

[0040] It should be noted that the environmental monitoring device 11 and the electronic device 12 can be independent devices or integrated into the same device; this application does not make any specific limitation in this regard.

[0041] When the environmental monitoring device 11 and the electronic device 12 are integrated into the same device, the communication method between the environmental monitoring device 11 and the electronic device 12 is the same as the communication method between the modules within the device. In this case, the communication process between the two is the same as that when the environmental monitoring device 11 and the electronic device 12 are independent of each other.

[0042] In the following embodiments provided in this application, the environmental monitoring device 11 and the electronic device 12 are described as being configured independently of each other.

[0043] In practical applications, the environmental monitoring method provided in this application embodiment can be applied to the environmental monitoring device 11, or to the devices included in the environmental monitoring device 11.

[0044] The environmental monitoring method provided in this application embodiment will be described below with reference to the accompanying drawings, taking the application of the environmental monitoring method to the environmental monitoring device 11 as an example.

[0045] Figure 2 A flowchart illustrating an environmental monitoring method provided in this application is shown below. Figure 2 As shown, the method includes the following steps:

[0046] S201. Obtain environmental monitoring data for each of the multiple first environmental monitoring points in the target area within a preset time period.

[0047] The target area includes wind farms and multiple first sub-regions. The ecological environment of each first sub-region is affected by the wind farms to varying degrees. The number of first environmental monitoring points in each first sub-region is positively correlated with the degree of impact of the wind farms on the first sub-region. Each first sub-region includes multiple second sub-regions. The ecological degradation of each second sub-region is different. The number of first environmental monitoring points in each second sub-region is positively correlated with the degree of ecological degradation of the second sub-region.

[0048] The target area can be any geographical region. For example, the target area can be a certain area around a wind farm on the Qinghai-Tibet Plateau. This application does not impose any specific restrictions on this.

[0049] The preset time period can be any length, for example, it can be 1 month, 6 months, or 12 months. The start or end time of the preset time period can be any time, and this application does not impose any specific restrictions on it.

[0050] One or more environmental monitoring devices may be installed at the first environmental monitoring point. Table 1 shows an example of an environmental monitoring device provided in this application.

[0051] Table 1

[0052]

[0053] As shown in Table 1, different environmental monitoring devices can monitor different environmental indicators. These devices can monitor the environment on the surface of the target area, the environment above the surface, or the environment below the surface. This application does not impose specific limitations on these aspects. Detailed descriptions of the various environmental monitoring devices in Table 1 can be found in existing solutions and will not be elaborated upon here.

[0054] Multiple first sub-regions may include wind farm disturbance regions, wind farm undisturbed regions, and wind farm damage regions.

[0055] The wind farm disturbance area can be the area downwind of the prevailing wind in the target area. The wind speed field, temperature field, and other ecological environment of the wind farm disturbance area are affected by the wind farm.

[0056] The undisturbed area of ​​a wind farm can be the area upwind of the prevailing wind in the target area. The wind speed field, temperature field, and other ecological environment of the undisturbed area are not affected by the wind farm.

[0057] The wind farm damage area can be the area surrounding the wind farm in the target area, where the ecological environment of the wind farm damage area is destroyed by the wind farm.

[0058] Multiple second sub-regions can include ecologically stable regions, ecologically risky regions, and ecologically degraded regions.

[0059] The ecologically stable region is the area in the first sub-region that is ecologically stable and has no ecologically degraded areas.

[0060] Ecological risk areas are those areas in the first sub-region where the ecology has not yet degraded, but there is a risk of ecological degradation.

[0061] Ecologically degraded areas are the ecologically degraded areas within the first sub-region.

[0062] As one possible implementation method, combined Figure 1 The environmental monitoring device sends a first request message to the electronic device. Upon receiving the first request message, the electronic device sends a first response message to the environmental monitoring device, which includes environmental monitoring data from each of the multiple first environmental monitoring points in the target area within a preset time period. Correspondingly, the environmental monitoring device receives the first response message from the electronic device and retrieves the environmental monitoring data from each of the multiple first environmental monitoring points in the target area within the preset time period from the first response message.

[0063] As another possible implementation method, combined with Figure 1 The environmental monitoring device sends a second request message to the electronic device. Upon receiving the second request message, the electronic device sends a second response message to the environmental monitoring device, which includes initial environmental monitoring data for each of the multiple first environmental monitoring points in the target area within a preset time period. Correspondingly, the environmental monitoring device receives the second response message from the electronic device and obtains the initial environmental monitoring data for each of the multiple first environmental monitoring points in the target area within the preset time period from the second response message.

[0064] As an example, after acquiring multiple initial environmental monitoring data, the environmental monitoring device interpolates the missing values ​​in each initial environmental monitoring data set to obtain the final environmental monitoring data. For example, the missing values ​​can be interpolated using an interpolation method; specific methods can be found in existing solutions, which will not be described further in this application.

[0065] As another example, after acquiring multiple initial environmental monitoring data, the environmental monitoring device interpolates the missing values ​​in each initial environmental monitoring data according to the interpolation method to obtain intermediate environmental monitoring data.

[0066] Subsequently, data indication information for outliers in the intermediate environmental monitoring data is obtained; the data indication information is used to indicate whether the outlier is accurate or inaccurate; if the data indication information indicates that the outlier is inaccurate, the outlier in the intermediate environmental monitoring data is removed; if the data indication information indicates that the outlier is accurate, the outlier in the intermediate environmental monitoring data is retained, thus obtaining the environmental monitoring data.

[0067] For outliers, the environmental monitoring parameters corresponding to the outlier can be re-collected at the environmental monitoring points where the outlier was collected. If the absolute value of the difference between the re-collected environmental monitoring parameters and the outlier is less than a preset threshold, the outlier can be considered accurate and valid, not an anomaly. The data indication information of the outlier indicates that the outlier is accurate, and accurate outliers can be retained to ensure the authenticity of the environmental monitoring data. If the absolute value of the difference between the re-collected environmental monitoring parameters and the outlier is greater than or equal to the preset threshold, the outlier can be considered invalid and an anomaly. The data indication information of the outlier indicates that the outlier is inaccurate, and it can be removed to ensure the accuracy of the environmental monitoring data.

[0068] S202. According to the preset selection ratio, determine a set of multiple second environmental monitoring points from multiple first environmental monitoring points in each second sub-region of the target area.

[0069] The second environmental monitoring point set includes multiple second environmental monitoring points, and each second environmental monitoring point set includes different second environmental monitoring points, with a preset selection ratio of less than 1. The fact that each second environmental monitoring point set includes different second environmental monitoring points means that the multiple second environmental monitoring points are not completely identical; different second environmental monitoring point sets may include some of the same second environmental monitoring points.

[0070] For example, the preset selection ratio can be 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, or 0.9. Of course, the preset selection ratio can also have other values, and this application does not impose specific limitations on this. Preferably, the preset selection ratio is 0.3-0.4. This avoids both an excessively large preset selection ratio resulting in too many second environmental monitoring points in the determined set, thus increasing the cost of environmental monitoring, and an excessively small preset selection ratio resulting in too few second environmental monitoring points, thus reducing the comprehensiveness of environmental monitoring.

[0071] In a scenario where multiple first sub-regions include wind farm disturbance areas, wind farm undisturbed areas, and wind farm damage areas, and multiple second sub-regions include ecologically stable areas, ecologically risk areas, and ecologically degraded areas, the number of second environmental monitoring points in each second sub-region of the wind farm damage area is greater than two; the number of second environmental monitoring points in the ecologically risk area of ​​the wind farm disturbance area is greater than two; and the number of second environmental monitoring points in the ecologically degraded area of ​​the wind farm disturbance area is greater than two. This ensures sufficient environmental monitoring points in areas with poor ecological environments, improving the accuracy of environmental monitoring.

[0072] As one possible implementation, taking a preset selection ratio of 0.2, the first sub-region of the target area is the wind farm disturbance area, the wind farm undisturbed area, and the wind farm damage area, and the second sub-regions included in the first sub-region are the ecologically stable area, the ecological risk area, and the ecologically degraded area.

[0073] If the number of primary environmental monitoring points in the ecologically stable area of ​​the undisturbed wind farm is 10, the number of primary environmental monitoring points in the ecologically risk area of ​​the undisturbed wind farm is 20, and the number of primary environmental monitoring points in the ecologically degraded area of ​​the undisturbed wind farm is 30.

[0074] The environmental monitoring device randomly selects 2 second environmental monitoring points from 10 first environmental monitoring points in the ecologically stable area of ​​the undisturbed wind farm area, 4 second environmental monitoring points from 20 first environmental monitoring points in the ecologically risk area of ​​the undisturbed wind farm area, and 6 second environmental monitoring points from 30 first environmental monitoring points in the ecologically degraded area of ​​the undisturbed wind farm area.

[0075] If the number of primary environmental monitoring points in the ecologically stable area of ​​the wind farm disturbance area is 20, the number of primary environmental monitoring points in the ecologically risk area of ​​the wind farm disturbance area is 30, and the number of primary environmental monitoring points in the ecologically degraded area of ​​the wind farm disturbance area is 40.

[0076] The environmental monitoring device randomly selects 4 second environmental monitoring points from 20 first environmental monitoring points in the ecologically stable area of ​​the wind farm disturbance area, 6 second environmental monitoring points from 30 first environmental monitoring points in the ecologically risk area of ​​the wind farm disturbance area, and 8 second environmental monitoring points from 40 first environmental monitoring points in the ecologically degraded area of ​​the wind farm disturbance area.

[0077] If the number of primary environmental monitoring points in the ecologically stable area of ​​the wind farm damage area is 30, the number of primary environmental monitoring points in the ecologically risk area of ​​the wind farm damage area is 40, and the number of primary environmental monitoring points in the ecologically degraded area of ​​the wind farm damage area is 50.

[0078] The environmental monitoring device randomly selects 6 second environmental monitoring points from 30 first environmental monitoring points in the ecologically stable area of ​​the wind farm damage area, 8 second environmental monitoring points from 40 first environmental monitoring points in the ecological risk area of ​​the wind farm damage area, and 10 second environmental monitoring points from 50 first environmental monitoring points in the ecologically degraded area of ​​the wind farm damage area.

[0079] After multiple random selections, multiple sets of secondary environmental monitoring points can be obtained.

[0080] It should be noted that if the product of the number of the first environmental monitoring points in the second sub-region and the preset selection ratio is not an integer, it can be rounded up or down to avoid the number of the second environmental monitoring points being non-integer.

[0081] S203. Determine the target environmental monitoring point set among multiple sets of second environmental monitoring points, and use the multiple second environmental monitoring points included in the target environmental monitoring point set as the target environmental monitoring points of the target area.

[0082] Wherein, the target parameter of the target environmental monitoring point set is the minimum value among the target parameters of multiple second environmental monitoring point sets, the target parameter is the absolute value of the difference between the statistical parameter corresponding to the second environmental monitoring point set and the statistical parameter corresponding to multiple first environmental monitoring points in the target area, and the statistical parameter is either the mean or the variance of the environmental monitoring data.

[0083] Understandably, the target environmental monitoring point is the environmental monitoring point in the target area where environmental monitoring equipment is actually deployed long-term. For other first environmental monitoring points besides the target environmental monitoring point, the environmental monitoring equipment can be removed after the target environmental monitoring point is determined.

[0084] As one possible implementation, for each of the multiple sets of second environmental monitoring points, the environmental monitoring device normalizes the environmental monitoring data of the multiple second environmental monitoring points in the set of second environmental monitoring points. Then, it calculates the average or variance of the normalized environmental monitoring data to obtain the statistical parameters corresponding to the set of second environmental monitoring points.

[0085] The environmental monitoring device normalizes the environmental monitoring data from multiple first environmental monitoring points within the target area. Then, it calculates the average or variance of the normalized environmental monitoring data to obtain the statistical parameters corresponding to the set of first environmental monitoring points.

[0086] It should be noted that the specific scheme for normalizing the data can refer to existing schemes, and will not be described in this application.

[0087] The environmental monitoring device calculates the difference between the statistical parameters corresponding to the second set of environmental monitoring points and the statistical parameters corresponding to the first set of environmental monitoring points, and uses the absolute value of the difference as the target parameter of the second set of environmental monitoring points.

[0088] The environmental monitoring device compares the magnitudes of target parameters of multiple sets of second environmental monitoring points, determines the set of second environmental monitoring points corresponding to the smallest target parameter as the target environmental monitoring point set, and further, uses the multiple second environmental monitoring points included in the target environmental monitoring point set as the target environmental monitoring points of the target area.

[0089] Based on steps S201-S203, environmental monitoring data from multiple first environmental monitoring points in the second sub-regions of different first sub-regions within the target area are acquired. Following a preset selection ratio, multiple sets of second environmental monitoring points are determined from these first environmental monitoring points. Subsequently, a target environmental monitoring point set is determined from these sets of second environmental monitoring points. The multiple second environmental monitoring points included in the target environmental monitoring point set are then used as the target environmental monitoring points for the target area. Since the ecological environment of each first sub-region is affected by wind farms to varying degrees, and the degree of ecological degradation varies in each second sub-region, the number of first environmental monitoring points within a second sub-region is positively correlated with the degree of ecological degradation in that sub-region. The statistical parameters corresponding to the target environmental monitoring point set are closest to the statistical parameters corresponding to the multiple first environmental monitoring points within the target area. Therefore, suitable target environmental monitoring points can be determined based on the different impacts of wind farms and the different ecological conditions, thereby improving the accuracy of environmental monitoring point determination and increasing the efficiency of environmental monitoring.

[0090] The above provides a general overview of the environmental monitoring methods provided in this application. The following section will provide further details on the environmental monitoring methods provided in this application.

[0091] Figure 3 A flowchart illustrating yet another environmental monitoring method provided in this application, as shown below. Figure 3 As shown, prior to S201, the environmental monitoring method provided in this application may also include the following steps:

[0092] S301. For each of the multiple first sub-regions within the target area, obtain the ecological baseline information of the first sub-region.

[0093] Here, the ecological baseline information can represent a set of information used to characterize the basic ecological environment status of the first sub-region under conditions where it is unaffected by wind farms or the impact is negligible. It is used to support the determination of the normalized vegetation index and topographic relief index of the first sub-region. In some embodiments, the ecological baseline information may include at least one of the following: historical remote sensing image data, vegetation cover / vegetation type distribution data, land use / cover type data, soil type and soil moisture content data, surface temperature data, precipitation and evapotranspiration data, digital elevation model data and its derived topographic factor data corresponding to the first sub-region.

[0094] As one possible implementation method, combined Figure 1 The environmental monitoring device sends a third request message to the electronic device. Upon receiving the third request message, the electronic device sends a third response message, including ecological baseline information for each first sub-region, to the environmental monitoring device. Correspondingly, the environmental monitoring device receives the third response message from the electronic device and obtains the ecological baseline information for each first sub-region from it.

[0095] S302. Determine the Normalized Difference Vegetation Index (NDVI) and Terrain Ruggedness Index (TRI) of the first sub-region based on the ecological baseline information of the first sub-region.

[0096] As one possible approach, the environmental monitoring device processes the ecological baseline information of the first sub-region based on a high-resolution DEM to obtain the NDVI and TRI of the first sub-region.

[0097] It should be noted that the specific implementation method can be found in existing solutions, and will not be described in detail here.

[0098] S303. Determine multiple second sub-regions within the first sub-region based on the NDVI and TRI of the first sub-region.

[0099] As one possible implementation, taking multiple second sub-regions including ecologically stable regions, ecologically risky regions, and ecologically degraded regions as an example, the environmental monitoring device determines the unit regions in the first sub-region where NDVI is greater than a first threshold and TRI is less than a second threshold as ecologically stable regions; determines the unit regions in the first sub-region where NDVI is less than the first threshold and TRI is less than the second threshold, or determines the unit regions in the first sub-region where NDVI is greater than the first threshold and TRI is greater than the second threshold as ecologically risky regions; and determines the unit regions in the first sub-region where NDVI is less than the first threshold and TRI is greater than the second threshold as ecologically degraded regions.

[0100] It should be noted that for a detailed description of this possible implementation method, please refer to the relevant description in the subsequent sections of the specific implementation method of this application, which will not be described here.

[0101] Based on S301-S303, by obtaining the ecological baseline information of the first sub-region, the NDVI and TRI of the first sub-region are determined. Since NDVI and TRI can reflect the state of the ecological environment in the region, multiple second sub-regions in the first sub-region can be determined based on the NDVI and TRI of the first sub-region.

[0102] Figure 4 This is a flowchart illustrating another environmental monitoring method provided in this application, where multiple second sub-regions include ecologically stable areas, ecologically risky areas, and ecologically degraded areas, such as... Figure 4 As shown, S303 provided in the specific embodiments of this application may specifically include the following steps:

[0103] S401. The unit area in the first sub-region where NDVI is greater than the first threshold and TRI is less than the second threshold is determined as the ecologically stable area.

[0104] It should be noted that the first threshold can be 0.8, 0.9 or 0.7. Of course, the first threshold can also have other values, and this application does not impose specific restrictions on this.

[0105] The second threshold can be 50, 100 or 75. Of course, the second threshold can also have other values, and this application does not impose any specific restrictions on this.

[0106] As one possible implementation, the environmental monitoring device determines whether each unit area in the first sub-region has an NDVI greater than a first threshold and a TRI less than a second threshold. If so, the unit area is determined to be an ecologically stable area; otherwise, the unit area is determined not to be an ecologically stable area.

[0107] S402. The unit areas in the first sub-region where NDVI is less than the first threshold and TRI is less than the second threshold, or the unit areas in the first sub-region where NDVI is greater than the first threshold and TRI is greater than the second threshold, are identified as ecological risk areas.

[0108] As one possible implementation, the environmental monitoring device determines whether each unit area in the first sub-region has an NDVI less than a first threshold and a TRI less than a second threshold, or an NDVI greater than the first threshold and a TRI greater than the second threshold. If so, the unit area is determined to be an ecological risk area; otherwise, the unit area is determined not to be an ecological risk area.

[0109] S403. The unit area in the first sub-region where NDVI is less than the first threshold and TRI is greater than the second threshold is identified as an ecologically degraded area.

[0110] As one possible implementation, the environmental monitoring device determines whether each unit area in the first sub-region has an NDVI less than a first threshold and a TRI greater than a second threshold. If so, the unit area is determined to be an ecologically degraded area; otherwise, the unit area is determined not to be an ecologically degraded area.

[0111] It should be noted that when adjacent unit areas are of the same type, that is, when adjacent unit areas are both ecologically stable areas, ecologically risk areas, and ecologically degraded areas, adjacent unit areas can be regarded as the same second sub-region.

[0112] Based on S401-S403, a larger NDVI indicates better vegetation cover in the region, while a smaller NDVI indicates worse vegetation cover. A larger TRI indicates greater surface roughness in the region, which in turn indicates stronger surface heterogeneity. Conversely, a smaller TRI indicates less surface roughness and weaker surface heterogeneity. Therefore, by comparing NDVI with a first threshold and TRI with a second threshold, ecologically stable, ecologically risky, and ecologically degraded areas within the first sub-region can be identified.

[0113] In some embodiments, the plurality of first sub-regions include a wind farm disturbance region and a wind farm undisturbed region. The environmental monitoring device can set the number of first environmental monitoring points in the ecologically stable region of the undisturbed wind farm region as a first value; set the number of first environmental monitoring points in the ecologically risk region of the undisturbed wind farm region as a second value; the second value is greater than the first value; set the number of first environmental monitoring points in the ecologically degraded region of the undisturbed wind farm region as a third value; the third value is greater than the second value.

[0114] For example, the first value can be 30, the second value can be 60, and the third value can be 90. Of course, the first, second, and third values ​​can also have other values, and this application does not impose specific restrictions on them.

[0115] The environmental monitoring device can set the number of the first environmental monitoring points in the ecologically stable area of ​​the wind farm disturbance area as the fourth value; the fourth value is greater than the first value; set the number of the first environmental monitoring points in the ecologically risk area of ​​the wind farm disturbance area as the fifth value; the fifth value is greater than the fourth value; set the number of the first environmental monitoring points in the ecologically degraded area of ​​the wind farm disturbance area as the sixth value; the sixth value is greater than the fifth value; the seventh value is less than the eighth value, the seventh value is the sum of the first, second and third values, and the eighth value is the sum of the fourth, fifth and sixth values.

[0116] For example, the fourth value can be 60, the fifth value can be 90, and the sixth value can be 120. Of course, the fourth, fifth, and sixth values ​​can also have other values, and this application does not impose specific restrictions on them.

[0117] Taking the above values ​​as examples, the seventh value is 180 and the eighth value is 270.

[0118] Because wind farms have a greater impact on the ecological environment of the target area in the disturbed area and a smaller impact in the undisturbed area, the ecological environment of the ecologically stable, ecologically risky, and ecologically degraded areas in both the disturbed and undisturbed areas gradually deteriorates. The ecological environment in areas with poor ecological environment has a greater need for monitoring. Based on the above scheme, the accuracy of ecological environment monitoring can be improved while reducing the cost of monitoring.

[0119] In some other embodiments, in addition to including the wind farm disturbance area and the wind farm undisturbed area, the multiple first sub-regions may also include the wind farm damage area. Based on the previous embodiment, the environmental monitoring device may further set the number of first environmental monitoring points in the ecologically stable area of ​​the wind farm damage area as a ninth value; the ninth value is greater than the fourth value; set the number of first environmental monitoring points in the ecological risk area of ​​the wind farm damage area as a tenth value; the tenth value is greater than the ninth value; set the number of first environmental monitoring points in the ecologically degraded area of ​​the wind farm damage area as an eleventh value; the eleventh value is greater than the tenth value; the twelfth value is greater than the eighth value, and the twelfth value is the sum of the ninth, tenth and eleventh values.

[0120] For example, the ninth value can be 90, the tenth value can be 120, and the eleventh value can be 150. Of course, the ninth, tenth, and eleventh values ​​can also have other values, and this application does not impose specific restrictions on them.

[0121] Taking the above values ​​as examples, the twelfth value is 360.

[0122] In cases where multiple first sub-regions also include wind farm damage areas, the ecological environment status of ecologically stable areas, ecologically risk areas, and ecologically degraded areas in the wind farm damage areas is relatively poor. The ecological environment monitoring needs of the areas with poor ecological environment are relatively large. Based on the above scheme, the accuracy of ecological environment monitoring can be improved while reducing the cost of ecological environment monitoring.

[0123] The above mainly describes the solution provided by the embodiments of this application from the perspective of environmental monitoring devices performing environmental monitoring methods. To achieve the above functions, the environmental monitoring device includes corresponding hardware structures and / or software modules for performing each function. Those skilled in the art should readily recognize that, in conjunction with the units and algorithm steps of the various examples described in the embodiments disclosed herein, the embodiments of this application can be implemented in hardware or a combination of hardware and computer software. Whether a function is executed by hardware or by computer software driving hardware depends on the specific application and design constraints of the technical solution. Those skilled in the art can use different methods to implement the described functions for each specific application, but such implementation should not be considered beyond the scope of this application.

[0124] This application embodiment can divide the environmental monitoring device into functional modules according to the above method example. For example, each function can be divided into a separate functional module, or two or more functions can be integrated into one processing module. The integrated module can be implemented in hardware or as a software functional module. Optionally, the module division in this application embodiment is illustrative and only represents one logical functional division; other division methods may be used in actual implementation. Furthermore, "module" here can refer to an application-specific integrated circuit (ASIC), a circuit, a processor and memory executing one or more software or firmware programs, integrated logic circuits, and / or other devices that can provide the above functions.

[0125] When using functional module division Figure 5 A schematic diagram of an environmental monitoring device is shown. Figure 5 As shown, the environmental monitoring device includes an acquisition module 501 and a processing module 502.

[0126] Specifically, the acquisition module 501 is used to acquire environmental monitoring data of each of the multiple first environmental monitoring points in the target area within a preset time period; a wind farm is set up in the target area, and the target area includes multiple first sub-areas. The ecological environment of each first sub-area is affected by the wind farm to a different degree. The number of first environmental monitoring points in the first sub-area is positively correlated with the degree of impact of the wind farm on the first sub-area. Each first sub-area includes multiple second sub-areas. The ecological degradation of each second sub-area is different. The number of first environmental monitoring points in the second sub-area is positively correlated with the degree of ecological degradation of the second sub-area.

[0127] The processing module 502 can be used to determine multiple sets of second environmental monitoring points from multiple first environmental monitoring points in each second sub-region of the target area according to a preset selection ratio; the set of second environmental monitoring points includes multiple second environmental monitoring points, and the multiple second environmental monitoring points included in each set of second environmental monitoring points are different, and the preset selection ratio is less than 1.

[0128] The processing module 502 is also used to determine the target environmental monitoring point set in the multiple second environmental monitoring point set, and to take the multiple second environmental monitoring points included in the target environmental monitoring point set as the target environmental monitoring points of the target area; the target parameter of the target environmental monitoring point set is the minimum value among the target parameters of the multiple second environmental monitoring point sets, the target parameter is the absolute value of the difference between the statistical parameter corresponding to the second environmental monitoring point set and the statistical parameter corresponding to the multiple first environmental monitoring points in the target area, and the statistical parameter is either the mean or the variance of the environmental monitoring data.

[0135] In another possible implementation, the memory 602 can also be integrated with the processor 601.

[0136] Bus 603 can be an Industry Standard Architecture (ISA) bus, a Peripheral Component Interconnect (PCI) bus, or an Extended Industry Standard Architecture (EISA) bus, etc. This bus can be divided into address bus, data bus, control bus, etc. For ease of representation, Figure 6 The bus is represented by a single thick line, but this does not mean that there is only one bus or one type of bus.

Figure 6 In addition to the components shown, the environmental monitoring device may include more or fewer components than illustrated, or combine certain components, or have different component arrangements.

[0138] As an example, combined Figure 5The functions implemented by the acquisition module 501 and the processing module 502 in the environmental monitoring device are the same as those of the acquisition module 501 and the processing module 502. Figure 6 The processor 601 in it has the same function.

[0139] Optional, such as Figure 6 As shown, the environmental monitoring device provided in this application embodiment may further include a communication interface 604.
