Method and system for constructing regional ecological security pattern based on geospatial big data

Abstract

The invention discloses a method and system for constructing a regional ecological security pattern based on geographic space big data. The method includes: determining the relationship between a plurality of environmental variables in the research area and the preset security pattern, and obtaining the data of the research area. The big data of ecological environment space, based on the relationship between multiple environmental variables in the research area and the preset security pattern, calculates the weight value of each environmental variable in the big data of ecological environment space, and constructs according to the weight value of each environmental variable A security pattern prediction model, obtaining a plurality of ecological indicators in the research area, constructing a plurality of target security pattern models in the research area according to the plurality of ecological indicators using the security pattern prediction model, and using each target security pattern model Output its corresponding security pattern distribution map. According to different security pattern models, researchers can obtain the security pattern distribution map corresponding to different ecological indicators, and the researcher's sense of experience.

Description

technical field [0001] The present invention relates to the technical field of regional ecological security pattern construction, in particular to a method and system for regional ecological security pattern construction based on geospatial big data. Background technique [0002] Since the 20th century, human activities have been constantly changing the evolution process of nature. The environmental damage and ecological security problems have been aggravated, which has threatened the political, social and economic security of countries or regions. The resulting conflicts and conflicts between countries or regions The increasing proportion of friction has become a major hidden danger affecting global security. The emergence of global and regional ecological security issues has become a turning point in the evolution of the entire human race towards ecological civilization. As the most basic security requirement for human survival and development, ecological security not onl...
