Description

Technical Field

[0001] The present invention relates to the technical field of data processing, and in particular to an environmental pollution status detection method for ecological restoration. Background Art

[0002] With the development of new technologies, ecological environment monitoring technologies are also constantly updated and developed. The detection of environmental pollution conditions in ecological restoration will focus on integrated monitoring of multiple parameters and multiple scales to achieve multi-angle detection of the ecological environment in order to adapt to more complex and diverse ecological and environmental problems. In the process of ecological restoration, it is very important to monitor and evaluate the quality of farmland soil. Through the detection of soil pH value, the concentration of nutrient elements in the soil and other technologies, the acidity and alkalinity of farmland soil and the nutrient status can be reflected, and the degree of pollution and distribution of pollutants in farmland soil can be understood. This can guide the progress of ecological restoration work, reasonably select restoration technologies and methods, and provide a scientific basis for the formulation and implementation of relevant policies to ensure the effectiveness and sustainability of ecological restoration.

Obviously, the drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying creative labor.

[0037] Figure 1 A schematic flow chart of a method for detecting environmental pollution conditions for ecological restoration provided by an embodiment of the present invention. DETAILED DESCRIPTION

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] See also Figure 1 , which shows a flow chart of an environmental pollution status detection method for ecological restoration provided by an embodiment of the present invention, the method comprising the following steps:

[0040] Step S001: Collect the time series data of soil pH value during the ecological restoration process to obtain the soil acid-base sequence, and record the ambient temperature data and ambient humidity data.

[0041] It should be noted that when analyzing the soil pH value during the ecological restoration process, due to the existence of external environmental factors such as weather temperature changes, seasonal precipitation and other environmental interference factors, the measured soil pH value cannot truly reflect the acidity and alkalinity of the soil during the ecological restoration process, and thus cannot accurately judge the environmental pollution of the soil; therefore, the purpose of this embodiment is to quantify the degree of interference of environmental changes on the soil pH value by analyzing the soil pH value in combination with ambient temperature data and humidity data, and finally obtain the degree of soil restoration that can truly reflect the soil pollution status.

[0042] Specifically, the pH value of the soil in the same plot of soil to be tested is monitored once every 12 hours using an acid-base sensor mounted on a drone. Due to the large temperature difference between noon and midnight, pH monitoring is carried out at 8 a.m. and 8 p.m., and a total of soil pH time series data for the past six months is collected to form a soil acid-base sequence. At the same time, while monitoring the soil pH value, the ambient temperature data and ambient humidity data are recorded using temperature sensors and humidity sensors. The sampling frequency and sampling duration are consistent with the soil pH value.

[0043] Step S002, segmenting the soil acid-base sequence according to the change of soil pH value to obtain a number of soil acid-base data segments; obtaining the environmental impact factor of each soil acid-base data segment according to the difference of soil pH value fluctuation in different soil acid-base data segments; obtaining the restoration impact factor of each soil acid-base data segment according to the change and overall distribution of soil pH values ​​adjacent in time series in the soil acid-base data segment.

[0044] Preferably, in one embodiment of the present invention, the soil acid-base sequence is segmented according to the change of soil pH value to obtain a number of soil acid-base data segments, including the specific method of:

[0045] It should be noted that during the changes in temperature and humidity, the moisture content in the soil will continue to change when the temperature and humidity are similar for a period of time. Then, due to the change in moisture content, the pH value will show the same trend change. It is necessary to segment the soil according to the changing trend of the soil pH value in the soil acid-base sequence. That is, the same changing trend is taken as the same data segment, and the soil acid-base data segments are divided according to the extreme points in the soil acid-base sequence.

[0046] Specifically, with time as the horizontal axis and soil pH value as the vertical axis, the coordinate axis is constructed and the change curve of the soil acid-base sequence is obtained. The change curve of the soil acid-base sequence is processed by the AMPD (automatic multi-scale peak search algorithm) algorithm to obtain several maximum points, and the change curve of the soil acid-base sequence is processed by axisymmetry about the horizontal axis to obtain a symmetrical curve. Based on the symmetrical curve, several minimum points are obtained by the AMPD algorithm; the maximum point, the minimum point, and the first soil pH value in the soil acid-base sequence are all used as segmentation points, and the soil acid-base sequence is divided into several soil acid-base data segments through the segmentation points, wherein each segmentation point is the first soil pH value in each soil acid-base data segment.

[0047] Preferably, in one embodiment of the present invention, the environmental impact factor of each soil acid-base data segment is obtained according to the difference in soil pH fluctuations in different soil acid-base data segments, and the specific method includes:

[0048] It should be noted that under the same trend change, that is, the ambient temperature data and the ambient humidity data are stable, the pH value will show the same trend change, but the change is usually small; if a drastic change occurs, resulting in a large difference in soil pH within the same soil acid-base data segment, it is more likely to be affected by greater weather. For example, high temperature and heavy rainfall will cause a large change in the water content in the soil, thereby affecting the fluctuation range of the soil pH value in the soil acid-base data segment.

[0049] Specifically, Environmental factors affecting soil acid-base data segments The calculation method is:

[0050]

[0051] in, and Respectively represent The standard deviation of soil pH value in the soil acid-base data segment and the The standard deviation of soil pH value in each soil acid-base data segment, Indicates the number of soil acid-base data segments in the soil acid-base sequence. represents the absolute value function.

[0052] It should be noted that by comparing the standard deviation of the current soil acid-base data segment with the standard deviation of other soil acid-base data segments, the greater the difference from the mean of the standard deviation, the more likely the standard deviation is to be too small or too large. If it is too large, the fluctuation range is too large, and the possibility of being affected by extreme weather is greater, and the corresponding environmental impact factor is greater; if it is too small, the soil pH value range of the soil acid-base data segment remains stable. During the ecological restoration process, soil pH values ​​with smaller changes may also be more affected by the environment, so their environmental impact factors are also larger.

[0053] Preferably, in one embodiment of the present invention, the restoration influencing factor of each soil acid-base data segment is obtained according to the change and overall distribution of the soil pH values ​​adjacent in time series in the soil acid-base data segment, and the specific method includes:

[0054] It should be noted that the soil pH value fluctuates around neutral 7, the acid-base substances in the soil environment are well balanced, and the soil acid-base conditions are moderate. In the process of quantifying the acid-base conditions of the soil during ecological restoration, for the soil acid-base data segment, the closer it is to neutral 7, the better the corresponding restoration, the smaller the possibility of subsequent restoration, and the smaller the corresponding restoration impact factor; at the same time, if soil acid-base restoration relies on restoration agents, the greater the difference in soil pH values ​​between adjacent time series, the greater the effect of the restoration agent, and the greater the restoration impact factor.

[0055] Specifically, Restoration influencing factors of soil acid-base data segments The calculation method is:

[0056]

[0057] in, Indicates neutral pH value, i.e. pH=7; Indicates The mean of all soil pH values ​​in the soil acid-base data segment, Indicates The number of soil pH values ​​in the soil acid-base data segment, Indicates In the soil acid-base data segment The soil pH value, Indicates In the soil acid-base data segment The soil pH value, represents the absolute value function.

[0058] At this point, the soil acid-base sequence is segmented according to the changing trend, and the environmental impact factor is quantified based on the fluctuation of soil pH value in the soil acid-base data segment, so as to present the possibility of being disturbed by environmental changes under the same changing trend. At the same time, based on the temporal changes and overall distribution range of soil pH value, the necessity and effect of the remediation agent for soil acid-base remediation are quantified to obtain the soil remediation parameters.

[0059] Step S003: Based on the changes in ambient temperature data and ambient humidity data, combined with the environmental influencing factors of the soil acid-base data segment, adjust the restoration influencing factors of the soil acid-base data segment to obtain the soil restoration parameters of each soil acid-base data segment; combined with the soil pH value in the soil acid-base data segment, obtain the soil restoration degree of each soil acid-base data segment.

[0060] Preferably, in one embodiment of the present invention, based on the changes in ambient temperature data and ambient humidity data, combined with the environmental impact factor of the soil acid-base data segment, the restoration impact factor of the soil acid-base data segment is adjusted to obtain the soil restoration parameters of each soil acid-base data segment, including the specific method of:

[0061] It should be noted that, based on the environmental influencing factors, the ambient temperature data and the ambient humidity data are analyzed separately. The ambient temperature data, that is, the increase in ambient temperature, will cause water evaporation; and the ambient humidity data, that is, the lower the relative humidity, the faster the soil moisture evaporation rate, and vice versa, the slower the evaporation rate. According to the changes in ambient temperature data and ambient humidity data, combined with the environmental influencing factors, the restoration influencing factors are adjusted to remove the interference of soil pH changes caused by the influence of temperature and humidity on soil moisture content.

[0062] Specifically, the environmental impact factors of all soil acid-base data segments are linearly normalized, and the results are used as the environmental impact weights of each soil acid-base data segment; the restoration impact factors of all soil acid-base data segments are linearly normalized, and the results are used as the restoration impact parameters of each soil acid-base data segment; all ambient temperature data are linearly normalized, and the results are used as the temperature factor at each moment; it is particularly noted that the ambient humidity data is collected as the relative humidity in the environment, so its interval range is ; then Soil remediation parameters for soil pH data segments The calculation method is:

[0063]

[0064] in, Indicates The mean value of all temperature factors within the time range corresponding to the soil acid-base data segment, Indicates The mean value of all environmental humidity data within the time range corresponding to the soil acid-base data segment, Indicates The environmental impact weight of each soil acid-base data segment, Indicates The restoration influencing parameters of each soil acid-base data segment, To avoid hyperparameters with a denominator of 0, this embodiment uses Give a narrative.

[0065] It should be noted that, based on the environmental impact weight, the higher the temperature or the lower the humidity, the easier it is for soil moisture to evaporate, and the lower the soil moisture content, resulting in the more likely that the soil pH value will change dramatically. The corresponding remediation impact factor should be adjusted smaller, that is, the greater the environmental interference, the smaller the remediation impact factor should be adjusted, thereby obtaining the soil remediation parameters.

[0066] Preferably, in one embodiment of the present invention, the soil pH value in the soil acid-base data segment is combined to obtain the soil remediation degree of each soil acid-base data segment, including the specific method of:

[0067] It should be noted that, based on the soil remediation parameters, the soil remediation degree is quantified according to the soil pH value distribution in the current soil acid-base data segment.

[0068] Specifically, Soil remediation degree of each soil acid-base data segment The calculation method is:

[0069]

[0070] in, Indicates Soil remediation parameters for each soil acid-base data segment, Indicates neutral pH value, Indicates The value of the last soil pH value in the soil acid-base data segment. represents the absolute value function.

[0071] It should be noted that the closer the deviation between the last soil pH value and the neutral pH value in the soil acid-base data segment is, the better the remediation effect is. At the same time, adjustments are made based on the soil remediation parameters to avoid interference from environmental factors in the soil pH monitoring process.

[0072] At this point, by analyzing the ambient temperature data and the ambient humidity data, the restoration influencing factors are adjusted on the basis of the environmental influencing factors, the soil restoration parameters are quantified, and the influence of environmental factor changes on the quantitative soil acid-base condition is removed to the greatest extent. In addition, the soil pH value is combined to quantify the degree of soil restoration in the corresponding time range of the soil acid-base data segment.

[0073] Step S004: judging the environmental pollution status of the soil during the ecological restoration process according to the soil restoration degree of the soil acid-base data segment.

[0074] Specifically, the soil remediation degree of any soil acid-base data segment is assigned to the moment corresponding to each soil pH value therein, and the soil remediation degree at each moment in the time range corresponding to the soil acid-base data segment is obtained. The first pollution threshold is preset, and 0.85 is used for description; the second pollution threshold is preset, and 0.55 is used for description; the third pollution threshold is preset, and 0.2 is used for description; if the soil remediation degree at any moment is greater than or equal to the first pollution threshold, the soil is slightly polluted at that moment; if the soil remediation degree is less than the first pollution threshold and greater than or equal to the second pollution threshold, the soil is moderately polluted at that moment; if the soil remediation degree is less than the second pollution threshold and greater than or equal to the third pollution threshold, the soil is severely polluted at that moment; if the soil remediation degree is less than the second pollution threshold and greater than or equal to the third pollution threshold, the soil is severely polluted at that moment; if the soil remediation degree is less than the third pollution threshold, the soil is extremely polluted at that moment; the environmental pollution status monitoring of the soil in the process of ecological restoration is completed.

[0075] At this point, this embodiment is completed.

[0076] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the principles of the present invention should be included in the protection scope of the present invention.
