Eco-mapping And Analysis Based On Natural Resource And Geo-spatial Database Of Zhejiang Province

Natural resources and geospatial information are important information resources and strategic resources of the country.After the information base is built,it is an important problem to combine the multi-service type,multi-scale and multi-source data together to analyze the information base better and visualize the analysis reasonably.The purpose of this study is to provide decision-makers with the ability to reveal the ecological environment of the decision-making area,and give a comprehensive,visual,quantitative,and spatial information to assist decision-makers to make better planning and management of ecological protection,and to utilize and protect natural resources.This paper comprehensively evaluates and analyzes the ecological environment,vulnerability,and uses mature model to evaluate the ecological environment of Zhejiang Province,and makes some improvements on the index system of comprehensive evaluation of vulnerability in Zhejiang Province.Principal component analysis is used to analyze the vulnerability of Zhejiang Province,using the visualization result as an example,to analyze ecological environment in Zhejiang Province,to solve the important issues,to make the appropriate response measures.This paper focuses on the characteristics of natural resources and geospatial information database in Zhejiang Province,and makes use of natural resources and geospatial information base,and establishes single factor index,single factor statistical index,special evaluation index,comprehensive evaluation index,forecast type index.This paper analyzes the research area and evaluates the ecological environment and vulnerability of Zhejiang Province,and carries out ecological mapping and ecological mapping analysis to synthesize complex and multi-source data,which can describe in detail the spatial and temporal distribution of ecological environment and their mutual The relationship makes the results more intuitive and persuasive.The index analysis system proposed in this paper provides a complete analytical method for the study of natural resources and geo-spatial information base,which is of reference significance for the ecological analysis of Zhejiang Province.
