Evaluation On Ecological Geological Environment Quality Of Tongzilin Town In Yanbian County

Since 1997,Yanbian County moved from Jiankang Town to Tongzilin Town,the construction of the new county building engineering,infrastructure construction and the construction of Jinhe resettlement areas made the construction of human engineering activities and farming activities,resulting in Tongzilin Town natural resource consumption,residents living conditions and production environment had undergone tremendous changes.Through the evaluation and research on the ecological geological environment quality of Tongzilin Town area in Yanbian County,classifying the ecological geological environment quality level,evaluating scientifically the regional ecological geological environment and construction land suitability,proposing scientific and rational planning and construction strategy,which was conducive to promote the coordinated development of regional socio-economic and ecological environment,which was also conducive to promoting the sustainable development of Tongzilin Town area and Yanbian county center city.Through surveys and data collection,using the method of remote sensing and GIS technology extracted Tongzilin Town geological,geographical and ecological environment and other information,combined with the research objectives to build suitable for Yanbian County Tongzilin Town eco-geological environment quality evaluation index system,and graded the evaluation index,to achieve the weighted synthesis of evaluation index information based on GIS platform,obtained the comprehensive evaluation grade and zoning result of ecological geology and environmental quality of Tongzilin Town,put forward the development strategy of Tongzilin Town regional planning.The research results include the following four aspects:(1)Cleared evaluation index system construction principles and indicators selection method,selected three primary evaluation indexes and eleven secondary evaluation indexes,established the evaluation index system of ecological geology and environmental quality of Tongzilin town.(2)Integrated Tongzilin Town of basic data and thematic data,extracted data layers such as geological hazard density,surface fluctuation degree and land use type.,and analyzed the spatial distribution characteristics of the data.(3)According to the evaluation index of ecological geology and environmental quality,using the analytic hierarchy process to calculate the weight of the indicators,applying the ArcGIS platform to weight the layers together,according to the statistical value distribution of the integrated layer,using natural breaks divided Tongzilin Town eco-geological environment quality into superior(?),good(?),middle(?),the difference(?)four levels,(4)Comprehensive eco-geological environment quality evaluation results and the overall planning of Yanbian County,proposed the optimization plan of urban space layout,industrial layout scheme,ecological security strategy and urban planning management optimization measures,srengthen the regional geological environment protection,promote Tongzilin Town economic and social comprehensive and sustainable development.
