| The Poyang Lake Ecological Economic Zone is a special economic zone officially approved by the State Council,and plays an important role in the social and economic development of Jiangxi Province.Based on the advanced general GIS platform,a database containing the geological background and socioeconomic indicators is established.Based on this,the powerful spatial analysis function of GIS is used to conduct spatial correlation analysis on the socioeconomic and geological background of the research area,and then reveal its Geography related patterns and internal laws of social economic development.(1)This article collects social economic data from 2012 to 2016 in the Poyang Lake District,including economic indicators such as total population,total industrial output value,GDP,medical beds,fiscal revenue,household deposits,cotton production,and fixed asset completion.SPSS22.0 software factor analyzed the economic data of Poyang Lake District in 2016,obtained the comprehensive economic strength score,and established an economic database;collected geological and terrain data of Poyang Lake District,including strata,lithology,structure,and a geological database was established;basic geographic data around Poyang Lake District were collected,including counties(cities,districts),major rivers,highways,and administrative The boundary line,etc.,established a geographic database.The establishment of the database laid the foundation for the spatial correlation analysis of the social economic and geological background of the Poyang Lake area.(2)Based on the established database,the spatial overlay analysis method of GIS was used to carry out geography-related analysis of population distribution,industrial output value,GDP and comprehensive economic strength.(3)Spatial correlation analysis shows that the counties and cities with stronger economic strength are mainly distributed in the plains of sedimentary rock areas,adjacent to the zoning boundaries of geological tectonic units,and spreading along the main rivers and transportation areas.The development of the three industries has enabled the city to develop rapidly.However,the comprehensive strength of the surrounding mountainous metamorphic rock hills is relatively weak,far away from the zoning boundaries of geological tectonic units,and poor connectivity of geographical landscapes,which limits the development of social economy.Some of these areas with relatively backward economic development are distributed in the Quaternary sedimentary area around Poyang Lake.Due to the low-lying terrain of the lake area,large changes in floods and water levels are the main factors affecting economic development.In areas where the economic development of the study area is relatively backward,due to the good connectivity of its geographic landscape,it can speed up the construction of its transportation infrastructure,and at the same time it also needs to solve the construction of flood control and farmland irrigation facilities in the lake area.Compared with regions with poor geographic connectivity,with various infrastructures in place,the Poyang Lake Ecological Economic Zone will become the most promising region in Jiangxi Province. |
