威海市城市垃圾填埋场选址地质环境适宜性评价

Suitability Evaluation of Geological Environment on Municipal Solid Waste Landfill Site in Weihai City

摘要:

威海是“最适宜人类居住的地方”,但随着城市建设的快速发展，城市垃圾产生量不断增加，垃圾填埋场选址问题亟待解决。以威海市环翠区为研究对象，综合考虑地形地貌、土地利用规划、交通、水利规划、气象、地质、水文地质、工程地质、环境地质等多方面因素及经济效益和环境效益，从地质环境角度出发，选取5个层次共15个评价因子，采用层次—网格法进行了垃圾填埋场选址区划分析研究，划分出垃圾可填埋区、限制填埋区、禁止填埋区。并在限制填埋区和可填埋区，进一步优选出几个垃圾填埋场地的首选场址，可供规划、设计部门参考。

Abstract:

Weihai city is the "most suitable place for people to live". But accompanying with rapid development of urban construction, the amount of municipal waste generation has been increasing, thus, landfill siting has to be resolved immediately. In this article, taking Huancui district of Weihai city as the study area, considering the topography, land use planning, transportation, water planning, meteorology, geology, hydrogeology, engineering geology, environmental geology and other factors and the economic and environmental benefits comprehensively, from geological point of view, selecting five levels with total 15 evaluation factors, by using level-grid method, the division of landfill site selection has been studied. It can be classifed into landfill refusing area, landfill restricting area and landfill prohibiting area. In landfill restricting area and landfill permitting area, several optimized landfill sites have been chosen in further, which can provide some references for designing and planning departments.
