specific Embodiment approach 1

[0014] Specific implementation mode 1: In this implementation mode, the method for regional comparison and evaluation of wetland biodiversity protection effectiveness based on reference benchmarks is implemented according to the following steps:

[0015] 1. Extract the land use raster data of the nature reserve in the two research areas from the range layer of the nature reserve, and then extract the ecological threat factor layer from the land use raster data of the two research areas, and use the InVEST model software In the environmental environment, input the ecological threat factor scale and the corresponding land use type sensitivity scale and protection layer, combine the land use data and the ecological threat factor layer, and output the Habitat quality index for a cell;

[0016] 2. Under the ArcGIS software environment, the arithmetic average processing is performed on the habitat quality index data of each grid unit of the nature reserves in the two research areas ...

specific Embodiment approach 2

[0021] Embodiment 2: This embodiment differs from Embodiment 1 in that the grid size in step 1 is 1000m.

specific Embodiment approach 3

[0022] Embodiment 3: The difference between this embodiment and Embodiment 1 or 2 is that the period between two adjacent periods in Step 1 is 5 years.

Abstract

The regional comparative evaluation method of wetland biodiversity protection effectiveness based on reference benchmarks should solve the practical problems that the existing evaluation of wetland biodiversity protection functions lacks regional comparability and the evaluation results are difficult to be applied. Comparative evaluation method: 1. Obtain the habitat quality index of each grid unit in multiple periods in the two study areas; 2. Calculate the multi-period average habitat quality index of the national nature reserve in the same study area, from its time series data Select the one with the largest value as the reference standard; 3. Subtract the reference standard of the respective research area from the habitat quality index of each grid unit in each period; 4. Through the time series of the relative quantities of the two study areas Change analysis, as well as comparative analysis of relative quantity development trends, to obtain comparative evaluation results. The invention constructs a method for regional comparison and evaluation of protection effectiveness by comparing the relative amount of biological diversity protection functions between regions, thereby providing a powerful tool for wetland biological diversity protection and management.

Description

technical field [0001] The invention relates to a method for evaluating biological diversity protection functions, in particular to a method for evaluating wetland biological diversity protection effectiveness areas based on reference standards. Background technique [0002] Ecosystem service function refers to the ecological system and its ecological process to form and maintain the natural environmental conditions and effects that human beings rely on for survival. The wetland ecosystem, known as the "kidney of the earth", can not only provide direct service products such as education, scientific research, tourism and leisure, animal and plant products, and peat, but also provide climate regulation, pollutant degradation, water conservation, and biodiversity. Indirect service products that maintain ecosystem stability, such as sexual protection. Biodiversity protection is the most important ecological service function of wetland ecosystems. Scientific evaluation of its bi...
