Regional ecological security pattern construction method and system based on geographic space big data

Abstract

The invention discloses a regional ecological security pattern construction method and system based on geographic space big data, and the method comprises the steps: determining the relation between a plurality of environment variables in a research region and a preset security pattern, and obtaining the ecological environment space big data of the research region, calculating a weight value of each environment variable in ecological environment space big data on the basis of a relationship between a plurality of environment variables in a research area and a preset security pattern, constructing a security pattern prediction model according to the weight value of each environment variable, and obtaining a plurality of ecological indexes in the research area; and constructing a plurality of target security pattern models of the research area by using the security pattern prediction model according to the plurality of ecological indexes, and outputting a corresponding security pattern distribution diagram by using each target security pattern model. The researcher can obtain the safety pattern distribution diagrams corresponding to different ecological indexes according to different safety pattern models, and the experience feeling of the researcher is improved.

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...
