Description

Technical Field

[0001] The present application relates to the technical field of ecological sensitivity analysis, and in particular to an estuary-based ecological sensitivity analysis method and system. Background Art

[0002] Ecological and environmental sensitivity refers to the sensitivity of an ecosystem to disturbances from natural and human activities within a region. It reflects the difficulty and likelihood of ecological and environmental problems occurring in a regional ecosystem when disturbed. Estuarine ecological sensitivity analysis plays a crucial role in assessing ecological security, ecosystem vulnerability, and ecological functional zoning. It helps to comprehensively understand the constraints imposed by natural resources and human activities on a specific region, thereby guiding decision-makers in formulating sustainable measures that optimally balance economic benefits and social well-being. In the analysis and assessment of ecological sensitivity, the species within an ecosystem are particularly important. However, existing assessments rely solely on changes in species abundance. This is due to the multi-factor influence of species abundance and the relatively limited data, resulting in unreliable results. Therefore, the continued use of standard ecological sensitivity analysis can lead to inaccurate assessments of ecological sensitivity in estuaries. Summary of the Invention

[0060] In summary, this application includes at least one of the following beneficial technical effects:

[0061] 1. Determine the basic adaptation value of the estuary's ecological environment based on the species profile of the estuary. Then, determine the ecological adaptation value of the ecological environment based on the difference in species abundance between the estuary and other areas due to human activities. This comprehensive ecological adaptation value of the estuary's ecological environment is then derived. Using climate to estimate human activity, the degree of environmental awareness in the estuary is combined with the degree of ecological damage, and finally, a comprehensive assessment of the estuary's ecological sensitivity is made. This detailed analysis of species in the ecosystem provides more reliable data and improves the accuracy of estuary-based ecological sensitivity analysis.

[0062] 2. Based on the environmental range to which species in the estuarine area are adapted and their survival conditions in unsuitable environments, the adaptability and regulatory capabilities of estuarine species are comprehensively reflected using their survival duration, current number, and the similarity between their original and real-time forms. This allows for an overall estimate of the contribution of estuarine species to the sensitivity of the estuarine ecological environment, providing a more reliable theoretical basis and improving the reliability of estuarine-based ecological sensitivity analysis.

[0063] 3. Based on climate change, we estimate the amount of human activity in estuaries. We then use the coverage and duration of environmental information campaigns in estuaries, combined with the rate of compliance with activity regulations, the proportion of estuaries in human development activities, and the number of participants to assess environmental awareness in estuaries. Public awareness indirectly influences ecological sensitivity, and assessing human activity based on actual climate is more consistent with estuary conditions, enhancing the practicality of estuary-based ecological sensitivity analysis. BRIEF DESCRIPTION OF THE DRAWINGS

[0064] Figure 1 It is a schematic diagram of the specific steps of an embodiment of an ecological sensitivity analysis method based on an estuary of the present invention.

[0065] Figure 2 This is a schematic diagram of module connections of an embodiment of an estuary-based ecological sensitivity analysis system of the present invention. DETAILED DESCRIPTION

[0066] Below is a combination of the embodiments and Figure 1-Figure 2 The present invention will be described in further detail, but the embodiments of the present invention are not limited thereto.

[0067] The present invention discloses an estuary-based ecological sensitivity analysis method, which specifically comprises the following steps:

[0068] Step S1: Collect species data of the estuary area and obtain the basic adaptation value of the estuary ecological environment based on the species data analysis.

[0069] Step S2: collecting historical ecological data of the estuary area, and obtaining the ecological adaptability value of the estuary ecological environment based on the analysis of the historical ecological data.

[0070] Step S3: combining the basic fitness value and the ecological fitness value to obtain the ecological environment fitness value of the estuary area.

[0071] The weight ratios of the basic adaptation value and the ecological adaptation value are set respectively, and the ecological environmental adaptation value is calculated according to the weight ratio. When the basic adaptation value and the ecological adaptation value are higher, it means that the adaptability of the ecosystem is stronger, and therefore the ecological environmental adaptation value is higher.

[0072] Step S4: Acquire climate data of the estuary area, and estimate the amount of human activities in the estuary area based on the climate data.

[0073] Step S5: acquiring human activity data, and evaluating the environmental awareness of humans in the estuary area based on the human activity data.

[0074] Step S6: The degree of human ecological damage in the estuary area is obtained by combining the amount of human activities and the degree of environmental awareness, and the ecological sensitivity value of the estuary is obtained by combining the ecological environment adaptability assessment.

[0075] In practical applications, scaling factors are set for human activity and environmental awareness, respectively, and the degree of ecological damage is calculated based on these scaling factors. Human activity disrupts the ecological environment, and greater human activity results in greater ecological damage. Higher environmental awareness, on the other hand, reduces ecological damage, resulting in lower degrees of ecological damage. Scaling factors are set for ecological damage and ecological adaptation, respectively, and the ecological sensitivity of the estuary is calculated based on these scaling factors. Ecological sensitivity refers to the difficulty and likelihood of ecological and environmental problems. Ecological sensitivity is influenced by external influences: greater ecological damage increases ecological sensitivity. It is also influenced by internal influences: higher ecological adaptation decreases ecological sensitivity. Lower ecological sensitivity indicates that the ecosystem is more resistant and resilient to external disturbances, maintaining relative stability in its structure and function. Higher ecological sensitivity, on the other hand, indicates that the ecosystem is more fragile and susceptible to external disturbances. A combined assessment of internal and external influences provides a more accurate assessment of the ecological sensitivity of an estuary.

[0076] The steps for collecting species data in the estuary area and analyzing the species data to obtain the basic adaptation value of the estuary ecological environment are as follows:

[0077] Step S11 : extracting species existing in the ecological environment of the estuary area based on the species data and recording them as estuary species.

[0078] Step S12: Obtain survival data of estuarine species, and obtain species adaptability of estuarine species based on statistics of the survival data.

[0079] Step S13: Acquire environmental data of the estuary area, and determine the species regulating capacity of the estuary species based on the environmental data.

[0080] Step S14: Calculate the species adaptability and the species regulatory ability according to a preset proportional coefficient to obtain a species adaptability value.

[0081] The greater the species' adaptability, the more adaptable it is and the less susceptible it is to external disturbances, so the greater the species' adaptability. The greater the species' regulatory capacity, the more able it is to adjust in time to changes in the external environment to reduce the impact on itself, so the greater the species' adaptability.

[0082] Step S15, counting the number of different estuarine species according to the species data, forming a weight ratio according to the number of estuarine species, and obtaining the basic adaptation value of the estuarine ecological environment by summing the species adaptation value and the corresponding weight ratio.

[0083] In practice, a weighted ratio is formed based on the number of estuarine species. This ratio is then multiplied by the corresponding species' fitness value and summed to obtain the basic fitness value. For example, if there are estuarine species A, B, and C with populations of 100,000, 200,000, and 700,000, respectively, the weighted ratios are 10%, 20%, and 70%. If the fitness values of estuarine species A, B, and C are 50, 60, and 80, respectively, the basic fitness value is 50 × 10% + 60 × 20% + 70 × 80% = 73. There is a mutually reinforcing relationship between species adaptability and ecological environment adaptability. The adaptive behavior of a species helps improve the conditions of its ecological environment, thereby enhancing the adaptive capacity of the entire ecosystem. Therefore, based on the species composition of an ecological environment, a preliminary basic fitness value can be obtained.

[0084] The steps for obtaining the survival data of estuarine species and obtaining the species adaptability of estuarine species based on the survival data are as follows:

[0085] Step S121 : obtaining ecological factors that affect the survival of estuarine species and recording them as influencing factors, and extracting environmental data of surviving estuarine species based on the survival data.

[0086] There are many ecological factors that affect the survival of estuarine species, such as river salinity, water temperature, dissolved oxygen, etc.

[0087] Step S122: extracting the extreme value range of the impact factor from the environmental data of the surviving estuarine species.

[0088] Estuarine species typically survive in more than one environment. This environment does not include the estuary. The range of environmental factors influencing survival can be derived from multiple other environments. For example, if species A survives in locations A, B, and C, and the water temperatures in these locations range from -1°C to 5°C, -10°C to 10°C, and 5°C to 15°C, respectively, then the temperature extremes range is -10°C to 15°C.

[0089] Step S123 , summing the differences of the extreme value ranges of all influencing factors to obtain the species adaptability of the estuarine species.

[0090] To sum the extreme ranges, first calculate the difference between the extreme ranges and then sum them. For example, if the water temperature extreme range is -10°C to 15°C, the difference is 25. If the salinity extreme range is 5g / L to 18g / L, the difference is 13. Adding 25 and 13 gives a species adaptability of 38.

[0091] In step S124, the extreme value ranges of all influencing factors are aggregated to form the survival range of estuarine species.

[0092] In practice, all extreme value ranges are combined to obtain the survival range of estuarine species, indicating that estuarine species can survive within this range. For example, the extreme range of water temperature is -10℃-15℃, and the extreme range of salinity is 5g / L-18g / L. These are the ranges within which estuarine species can survive.

[0093] The steps for obtaining environmental data of the estuarine area and determining the species regulating capacity of estuarine species based on the environmental data are as follows:

[0094] Step S131 , obtaining the survival history data of estuarine species, and extracting the existence duration, current number and original form of the estuarine species based on the survival history data.

[0095] Step S132: obtaining the real-time morphology of the estuarine species and comparing the original morphology with the real-time morphology to obtain the morphological similarity.

[0096] The similarity between the original form and the real-time form is compared using an existing similarity model, such as cosine similarity.

[0097] Step S133 , combining the existence duration, current number and morphological similarity to obtain the basic regulating capacity of estuarine species.

[0098] The basic adaptive capacity of estuarine species is calculated using weighted ratios for duration of existence, current population, and morphological similarity. The longer a species has existed on Earth, the more environmental changes it has experienced. This has prompted species to continuously accumulate adaptive traits over the long process of evolution to cope with various environmental changes. The current population of a species, to a certain extent, reflects its ability to adapt to the environment. Species with larger populations generally have stronger survival and reproductive capacities, and are able to maintain population stability under various environmental conditions. Significant differences between a species' original morphology and its current morphology indicate that the species has undergone significant adaptive changes during evolution, resulting in a stronger ability to adapt to the environment.

[0099] Step S134, determining whether the environmental data of the estuary area is within the survival range of the estuary species. If it is within the survival range of the estuary species, the basic regulating force is used as the species regulating force of the estuary species.

[0100] For example, the survival range of water temperature is 5℃-15℃, but the water temperature environment at the estuary is 0℃-10℃, which is not within the survival range.

[0101] Step S135: If the species is not in the survival range of the estuarine species, the difference between the environmental data and the survival range is compared, and the species regulating force is obtained by combining the basic regulating force.

[0102] In actual application, if the estuarine environment is not within the survival range, it means that when the species reaches the estuarine area to survive, it makes further adjustments based on the estuarine environment, indicating that the species' regulatory ability is greater than imagined. Therefore, it is necessary to further confirm and analyze it in combination with the basic regulatory ability.

[0103] If the species is not within its range, the difference between the environmental data and the range is compared, and the steps to obtain the species regulating capacity are combined with the basic regulating capacity. Specifically,

[0104] Step S1351: extract the range of the influencing factors of the estuary area based on the environmental data and record it as the real-time range.

[0105] For example, if the influencing factor is water temperature, the water temperature range of the estuary area is extracted as the real-time range.

[0106] Step S1352: compare the real-time range with the survival range, find the impact factors whose real-time range is not within the survival range, and record them as change factors.

[0107] Because there are many influencing factors, not every factor is outside the survival range. For example, if the water temperature range is outside the survival range, the water temperature is recorded as a variable factor. If the salinity range is within the survival range, the salinity is not recorded as a variable factor.

[0108] Step S1353: Calculate the range difference between the real-time range of the change factor and the corresponding survival range.

[0109] For example, if the variation factor is water temperature, and the survival range is 5°C-15°C, while the real-time range is 0°C-10°C, then the minimum difference is 5, and the maximum is within the survival range, so the range difference is 5. The range difference calculates the difference between values that are not within the real-time range and are not within the survival range. If the real-time range is 0°C-20°C, the maximum difference is 5, and the minimum difference of 5 is added to the maximum difference, resulting in a range difference of 10.

[0110] Step S1354: accumulate all range differences to obtain the environmental regulating force of estuarine species, and combine the environmental regulating force and the basic regulating force to obtain the species regulating force.

[0111] In practice, a larger range difference indicates a greater species' regulatory capacity, as it can adapt to a wider range of environments. A weighted ratio is set for the environmental regulatory capacity and the basic regulatory capacity, and the species' regulatory capacity is calculated based on this weighted ratio. As species adapt to new environments in estuaries, their regulatory capacity increases. Therefore, the actual regional regulatory capacity is calculated by combining this with the basic regulatory capacity. When both the environmental regulatory capacity and the basic regulatory capacity are greater, the species' regulatory capacity also increases.

[0112] The steps for collecting historical ecological data of the estuary area and analyzing the historical ecological data to obtain the ecological adaptability value of the estuary ecological environment are as follows:

[0113] Step S21 , obtaining human activities that affect the survival of estuarine species and recording them as impact activities, and statistically analyzing the changes in the number of estuarine species under different impact activities to form an impact activity-species number change curve.

[0114] Some human activities affect the survival of estuarine species, such as sewage discharge, fishing, and fishing. These activities reduce species numbers, leading to changes in species populations. Species population changes refer to decreases or increases in the number of species. The average change in population for each activity is calculated to form an impact activity-species population change curve. For example, if sewage discharge at location A causes a decrease of 10,000 individuals of Species A, while the original population was 20,000, the decrease is 50%. The same level of sewage discharge at location B causes a decrease of 20,000 individuals of Species A, while the original population was 100,000, the decrease is 20%. The average value is 35%, so the change in species population corresponding to the sewage discharge activity is a 35% decrease. Curves are constructed based on different levels of sewage discharge, meaning that there are corresponding changes in species population for each level of sewage discharge, allowing for the formation of a curve. Different impact activities have corresponding impact activity-species population change curves.

[0115] Step S22 , collecting historical activity data of the estuary area, and finding the corresponding species population change from the impact activity-species population curve based on the historical activity data, and recording it as the standard population change.

[0116] Based on the historical activity, find the coordinate point on the impact activity-species population curve that corresponds to the impact activity of the same type and degree as the historical activity. Then, use this curve coordinate point to find the corresponding species population change. For example, if the sewage discharge pollution level is 0.5mg / L and the corresponding species population change is a 5% decrease, then the standard population change is a 5% decrease.

[0117] Step S23 , searching for changes in the number of estuarine species in the estuarine area corresponding to the historical activity data and recording the changes as real-time number changes.

[0118] The actual quantity changes are counted. For example, when the sewage discharge pollution level is 0.5 mg / L, the actual number of species decreases by 8%, and the real-time quantity change is a decrease of 8%.

[0119] Step S24 , calculating the quantity difference between the standard quantity change and the real-time quantity change, summing the quantity differences under all impact activities, and obtaining the ecological adaptation value.

[0120] For example, if the difference in sewage discharge is -3% and the difference in fishing is 5%, the ecological adaptation value is 2%. Negative values indicate that species living in estuaries are more vulnerable to harm, while positive values indicate that species living in estuaries are better protected by the estuary ecosystem.

[0121] In practice, the adaptability of species and the adaptability of their ecosystems are interdependent. A species' adaptability depends not only on its own genetic and physiological characteristics but also on the ecological environment in which it lives. Human activities can directly impact organisms, leading to changes in species abundance, while the impact of the ecological environment can also cause changes in abundance. For example, if the standard abundance change is a 5% decrease and the real-time abundance change is an 8% decrease, in an estuarine ecosystem, under the same pollution conditions, the abundance decrease will be greater in the estuary, indicating that the ecosystem's protection capacity is poor and the ecological adaptability value is low. If the real-time abundance change is a 3% decrease, then the ecosystem is providing some protection, minimizing damage to the species and reflecting the ecosystem's greater adaptability and a higher ecological adaptability value.

[0122] The steps for obtaining climate data of the estuary area and estimating the amount of human activities in the estuary area based on the climate data are as follows:

[0123] Step S41 , calculating the average human activity under different climates and establishing a climate-human activity table.

[0124] Unlike other land areas, estuaries are affected by climate. For example, on sunny days, abundant sunlight and warmer water temperatures favor the activity and reproduction of aquatic life. Consequently, fishermen tend to fish on sunny days, as fish are more active and their success rate is relatively high. On rainy days, increased rainfall and river flow can cause changes in estuary water quality, such as lower salinity and lower water temperature. These changes can affect fish activity and distribution, prompting fishermen to adjust their fishing strategies or even suspend fishing activities.

[0125] Step S42: set a time period, collect climate data of the estuary area within the time period, and count different climate quantities according to the climate data.

[0126] Climate distribution varies across time periods. For example, summer is the hottest season in the estuary region, but it also experiences the most rainfall. During this period, temperatures are high, humidity is high, rainfall is concentrated, and typhoons may also affect the region. Therefore, climate conditions vary across time periods, so selecting the appropriate time period for evaluation provides more accurate results.

[0127] Step S43: The human activity amount corresponding to the climate is obtained by searching the climate-human activity table, and multiplied by the corresponding climate quantity to obtain the total amount of human activities corresponding to different climates in the time period.

[0128] For example, on sunny days, the average human activity in the estuary area is 30 people per square kilometer, while on rainy days, it averages 5 people per square kilometer. Let's assume that the time period is February to March, when there are more sunny days, with an average of 50 sunny days and 10 rainy days. Therefore, the total human activity on sunny days is 30 × 50 = 150, and the total human activity on rainy days is 5 × 10 = 50.

[0129] Step S44: superimpose the total amount of human activities in all climates to estimate the amount of human activities in the estuary area.

[0130] In practice, by adding up the total amount of human activity under all climate conditions, we can estimate the amount of human activity during that time period. For example, if a time period consists of only sunny and rainy days, the total human activity for both sunny and rainy days can be added together: 150 + 50 = 200. Estimating human activity can help us estimate the extent of human damage to the estuary's ecological environment and thus assess its impact on ecological sensitivity.

[0131] The steps to obtain human activity data and evaluate the environmental awareness of people in the estuary area based on the human activity data are as follows:

[0132] Step S51: Collect environmental protection publicity information in the estuary area, and extract the environmental protection publicity coverage area and environmental protection publicity duration based on the environmental protection publicity information.

[0133] Obtain publicity points for environmental protection publicity information, determine the coverage area of environmental protection publicity based on the publicity points, and calculate the duration of environmental protection publicity. Environmental protection information can be uploaded by users or collected from public environmental protection information in the future.

[0134] Step S52: Obtain the environmental protection publicity degree according to the environmental protection publicity coverage area and the environmental protection publicity duration.

[0135] The weight ratios of the environmental protection publicity coverage area and the environmental protection publicity duration are set respectively, and the environmental protection publicity degree is calculated based on the weight ratio. The larger the environmental protection publicity coverage area and the longer the environmental protection publicity duration, the greater the degree of environmental protection publicity, that is, the greater the degree of environmental protection publicity.

[0136] Step S53: Obtain the activity rules of the estuary area, calculate the compliance rate of people in the estuary area with the activity rules, and obtain the environmental protection attitude in combination with the environmental protection publicity.

[0137] As a unique zone where saltwater and freshwater meet, human activities in estuaries are constrained and influenced by a variety of factors. For example, it's crucial to rationally develop and utilize resources like fisheries, shipping, and water conservancy, and to establish resource utilization rules to avoid overfishing and overexploitation. Measuring compliance with these rules can reveal a person's actual environmental attitude. By setting proportional coefficients for compliance and environmental awareness, we can calculate environmental attitude based on these coefficients. A higher compliance rate indicates greater environmental awareness and a stronger environmental attitude. Greater environmental awareness and more effective promotion also contribute to a stronger environmental attitude.

[0138] Step S54, obtaining development activity information of the estuary area, analyzing the development activity information to obtain the importance of the estuary area, and combining the environmental protection attitude to obtain the environmental protection awareness of people in the estuary area.

[0139] In practical applications, confirming the public's environmental awareness can be combined with the actual amount of human activities to evaluate the damage caused by the external environment to the ecological environment, thereby obtaining a more accurate ecological sensitivity assessment and analysis.

[0140] The steps for obtaining development activity information of the estuary area, analyzing the development activity information to obtain the importance of the estuary area, and combining the environmental protection attitude to obtain the environmental awareness of the people in the estuary area are as follows:

[0141] Step S541 , obtaining development activity information of the estuary area, extracting the proportion of the estuary area in the development activities based on the development activity information and recording it as the activity proportion.

[0142] There are many development activities in estuaries, such as construction, tourism, and fishing. Some of these activities, such as fishing and tourism, are dependent on estuaries. The activity share is calculated by calculating the ratio of the number of activities that are dependent on estuaries to the total number of activities.

[0143] Step S542: Obtain the number of people participating in the estuary area activities and record it as the number of active people. Combined with the activity proportion, the importance of the estuary area is obtained.

[0144] The proportional factors of the number of people involved in activities and the proportion of activities are set respectively, and the importance of the estuary area is calculated based on the proportional factors. The more activities that rely on the estuary area for development and the more people who rely on the estuary area for survival, the more important the estuary area is.

[0145] Step S543 , respectively setting the scale factors of the importance of the estuary area and the environmental protection attitude, and calculating the environmental protection awareness of people in the estuary area based on the scale factors.

[0146] In practical application, the greater the environmental attitude, the more attention people in the estuary attach to environmental protection. The more important the estuary is to human life, the more people in the estuary will pay attention to protecting the estuary to reduce the impact of the estuary on themselves, thus having a greater degree of environmental awareness.

[0147] An estuary-based ecological sensitivity analysis system, by applying the above-mentioned estuary-based ecological sensitivity analysis method, includes:

[0148] The basic adaptation module collects species data in the estuary area and obtains the basic adaptation value of the estuary ecological environment based on the species data analysis.

[0149] The ecological adaptation module collects historical ecological data of the estuary area and obtains the ecological adaptation value of the estuary ecological environment based on the analysis of historical ecological data.

[0150] The environmental adaptation module combines the basic adaptation value and the ecological adaptation value to obtain the ecological environmental adaptation value of the estuary area.

[0151] The human activity module obtains climate data of the estuary area and estimates the amount of human activities in the estuary area based on the climate data.

[0152] The environmental awareness module obtains human activity data and evaluates the environmental awareness of humans in the estuary area based on the human activity data.

[0153] The ecological sensitivity module combines the amount of human activities and environmental awareness to analyze the degree of human ecological damage in the estuary area, and combines the ecological environment adaptability assessment to obtain the ecological sensitivity value of the estuary.
