Abstract

The invention relates to the technical field of environmental engineering, in particular to a GIS-based refuse landfill site selection method. The method comprises the following steps: S1, acquiring geographic data; S2, digitizing the geographic data into graphic data by using geometrical bodies and graphic symbols, and storing the graphic data into a newly-built spatial geographic database; S3, making each GIS thematic map; S4, performing spatial analysis on each GIS thematic map; S5, establishing a comprehensive evaluation system hierarchical structure model for site selection of the refuselandfill, and performing suitability index analysis on the candidate regions of the refuse landfill; and S6, outputting an optimal refuse landfill site selection map. According to the method of the invention, based on the GIS platform, after suitability analysis is carried out by utilizing the spatial analysis function and the hierarchical structure model of the GIS platform, a result is visuallyoutput, the method can be quickly and accurately used for quickly selecting the refuse landfill with less influence on the surrounding environment, and the cost is reduced.

Description

technical field [0001] The invention relates to the technical field of environmental engineering, in particular to a GIS-based site selection method and device for a garbage landfill. Background technique [0002] The site selection requirements for urban garbage disposal sites in my country are only open land, close to the city, and enough garbage can be accommodated, and rarely consider comprehensively the issue of site selection for garbage disposal sites. Therefore, the accumulation of garbage has caused serious environmental problems. question. The selection of the site of the garbage disposal site involves the development of the local economy, transportation, etc., geographical and topographical conditions, climate conditions, environmental geological conditions, surface hydrological conditions, and hydrogeological engineering geological conditions. It is a comprehensive work. This work helps urban planning and land management departments to better plan land use, and i...
