Method and system for determining biodiversity protection key area

Abstract

The invention discloses a method and a system for determining a biodiversity protection key area. The method comprises the following steps: acquiring environmental data and important species data of each area of an ecological system; analyzing the acquired environmental data and important species data of each region; obtaining an environmental influence coefficient and a species rich value; comparing the environmental influence coefficients and the species rich values with corresponding environmental coefficient threshold values and rich threshold values; when the corresponding area is in a to-be-verified state, collecting dynamic browsing information of the ecological environment of the corresponding area from a third-party website, and analyzing the browsing information to obtain an attention value of the corresponding area; obtaining a threat coefficient of the corresponding region in combination with the species rich value, the environmental influence coefficient and the attention value of the corresponding region; determining threat coefficients of a to-be-verified area in combination with multiple factors, and determining key areas of biodiversity protection according to the threat coefficients; and the result has more reference significance.

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 irreplaceable analysis, hotspot area analysis and other methods, 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 division results can only reflect the characteristics of animals, plants and the environment, lack of systematicness and comprehensiveness, and fail to reflect the current status and characteristics of the regional ecology; and it is impossible to reasonably assign corresponding collectors to collect data according to the collection and distribution values, improve data collection efficiency and ensure data collection Accuracy of collection
