Wetland biodiversity protection effect area contrast assessment method based on reference bases

Abstract

The invention provides a wetland biodiversity protection effect area contrast assessment method based on reference bases in order to solve practical problems of lack of the area comparability of conventional wetland biodiversity protection function assessment and difficult application of assessment results. The contrast assessment method includes: firstly, obtaining habitat quality indexes of eachgrid unit in multiple periods in two research areas; secondly, calculating multi-period habitat quality indexes of national natural reserves in the same research areas, and selecting the maximum values in time sequence data thereof as the reference bases; thirdly, subtracting the reference bases of the research areas respectively by the habitat quality indexes of the grid units of each period; and fourthly, obtaining a contrast assessment result through a time sequence change analysis of a relative quantity of the habitat quality indexes of the two research areas and a relative quantity development trend contrast analysis. According to the method, the protection effect area contrast assessment method is constructed through the contrast mode between the areas of the relative quality of thebiodiversity protection function so that a powerful tool is provided for wetland biodiversity protection 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...
