Embodiment 1

[0026] figure 1 It is a flowchart of a site selection method for a landfill based on a geographic information system (Geographic Information System, GIS) provided by an embodiment of the present application. like figure 1 As shown, the site selection method includes the following steps:

[0027] S110: Determine the overall number of landfills and the number of various types of landfills based on the overall planning of the designated city. This data is obtained from the relevant city administration of the designated city.

[0028] S120: Based on the geographic information system, multiple candidate areas of landfills around the designated city are obtained, and the number of candidate areas is equal to the overall number, denoted as M.

[0029] In this application, the number of types of landfills is assumed to be N.

[0030] Specifically, obtaining the candidate region includes the following steps:

[0031] S1201: Establish databases, including topography, cadastre, admi...

Abstract

The invention discloses a GIS-based refuse landfill site selection method. The method comprises the steps that the overall number of refuse landfills and the number of various refuse landfills are determined based on overall planning of a specified city; obtaining candidate areas of a plurality of refuse landfills around the designated city based on a geographic information system; according to the number of various refuse landfills, allocating the types of the refuse landfills to each candidate area, and obtaining multiple groups of configuration schemes; obtaining a first comprehensive evaluation value of each group of configuration schemes and sorting the first comprehensive evaluation values from high to low; and taking the configuration scheme with the first comprehensive evaluation value ranking as the optimal scheme. According to the method, site selection of a plurality of refuse landfills involved in urban unified planning is taken as a target, comprehensive evaluation of configuring various refuse landfills is considered, and a scientific and reasonable site selection scheme is made for the refuse landfills of the whole city.

Description

technical field [0001] This application relates to the technical field of environmental engineering, in particular to a GIS-based site selection method for landfills. Background technique [0002] The landfill is a place where garbage is piled up under the sanitary landfill method. Because of low cost and good sanitation, landfills are widely used in China, but landfills still have a certain impact on the surrounding environment. As the society's requirements for environmental protection are getting higher and higher, it is particularly important to reasonably select the address of the landfill to minimize the impact on the surrounding environment. [0003] At present, in the unified planning of urban waste landfills, the location configuration of various types of waste landfills has a greater impact on society and economy in later use. There is no relevant public proposal yet. Contents of the invention [0004] The purpose of this application is to provide a GIS-based ...
