Suitability Assessment, Urban Geological Environment And Urban Development In Wenshan

Based on geo-environment in Wenshan basin,setting out from the factors of topography,the geotechnical character,environmental hydrology geotechnical character,geological hazards and construction to appraise feasibility evaluation between city geological environment and urban development.The Wenshan basin is karst faulted basin,the main rock is carbonate,clay and clastic.There are clay in upper tertiary system and loose soil in quaternary,in the basin. weathering marlite and gravelly soil is the rock layer.The evolution and ore-bearing property,annealing,structural framework and the part of topography and morphology in the basin is depend on the north west Wenma split,the style of groundwater of basin is karst water,the gulf of mexico andfissure water.The environmental geological issues are groundwater pollution,geological hazards and the engineering geological problem of expansive clay.Based on the basic geological research and research on the spot,I summarize the quality and Vulnerability of groundwater,engineering geological partition and the suitability evaluation of building foundation,the fatalness of geological hazards and regional stability,then combined ten estimated factors of landform,the geotechnical character,environmental hydrology geotechnical character,geological hazards and construction which is the main factor of influencing geological environment quality.Then setting up the system of an integrated indicator systems of geological environment quality in Wenshan,depended on the system of basin mass index to sum up suitability evaluation of the quality of soil environment and urban development in Wenshan。The geological environment quality at present of the city of Wenshan is at in etc.-better level,it is seasoned with the request of urban construction ordinarily. geo-environment in Wenshan is not only good for the development of Wenshan but also restrict the development.The city cann' t become big city because of the lack of sustainable using water resource and sustainable use of land resource,and geological hazards is an another restricted factor.The reaction of planning and construction should be considered at the moment of urban development is seasoned with geo-environment to gain scientific development,sustainable development ends.We should make use of rationality,control the size of city,renovate geological hazards presently and inspect,geological hazards easy - happening areas to avoid expense.
