Method and system for determining biodiversity protection critical area

Abstract

The invention discloses a method and a system for determining a biodiversity protection critical area. The method comprises steps as follows: performing ecological sensitivity analysis on each area ofan ecological system to obtain an ecological sensitivity analysis result; simulating potential habitats of important species in the ecological system to obtain a simulation result; evaluating a service function of the ecological system to obtain an evaluation result; determining weight of the ecological sensitivity analysis result, the simulation result and the evaluation result with an analytichierarchy process; determining the biodiversity protection critical area with a natural breakpoint method of an ArcGIS spatial analysis function. With adoption of the method and the system, systematicness and comprehensiveness of an identification process are improved, and analysis efficiency of the biodiversity protection is improved.

Description

technical field [0001] The invention relates to the field of ecology, in particular to a method and system for determining key areas for biodiversity protection. Background technique [0002] Biodiversity is the material basis for the survival and development of human society. It has important ecological service functions such as supply, regulation, support, and culture, and plays an irreplaceable role in maintaining ecological balance. Biodiversity loss has become one of the major environmental issues of widespread concern to the international community. The threats it faces urgently require practical protection measures and management methods. Affected by factors such as the uneven distribution and the difference in the degree of threat, the protection work has different priorities. Conservation actions should have clear targets or key objects (regions or taxa, etc.). Therefore, identifying key areas for biodiversity conservation has become the primary task of formulating...

Problems solved by technology

[0003] Existing studies have pointed out the vacancy of biodiversity protection through methods such as irreplaceable analysis and hotspot area analysis, which is of positive significance, but there are also certain limitations. They either use ecosystem types or animal and plant attributes as the basis for hotspot area division , the classification results can only reflect the characteristics of animals, plants and habitats, lack of systematicness and comprehensiveness, and fail to reflect the current status and characteristics of regional ecology; moreover, the methods adopted are different, and the lack of unified standards leads to low efficiency in the analysis of biodiversity conservation
