The Location Research Of The Garbage Disposal Industrial Park Based On The AHP-GIS Model

With the rapid growth of the national economy,China has entered a new stage of urbanization development.urban waste as a product of urban development,its problems are more and more serious.As a waste treatment industry park,it can reduce the cost of garbage disposal,enhance the use of waste resources,and promote the healthy development of the city.Therefore,the location of waste treatment industry park is of great significance to the development of urban space.First of all,based on the existing research at home and abroad,this paper puts forward the necessity of research on the site selection of waste disposal industrial park.Then,through the methods of literature review and expert interview,the theory,concept and method of site location are discussed.At the same time,from the requirements of urban planning,the factors affecting the location of general industrial parks and the technical specifications of the waste disposal industry,a comprehensive analysis of the various indicators of factors,formed a three main factors,15 sub-factors constitute the site Evaluation System.Then the focus of the paper is to build the waste disposal industrial park location model.Through the analysis of the location method of the commonly used waste disposal industrial park,the location index model of AHP-GIS method is selected.The AHP-GIS location model of the waste disposal industrial park is the weight value of the location index factor obtained by the analytic hierarchy process,and then the location index factor is quantified into the parameters that can be used in the GIS spatial model.The location index value obtained by the analytic hierarchy process is imported into the Arc GIS software,and the final site selection result is obtained by using the GIS spatial analysis method.Finally,based on the AHP-GIS model,combined with the data obtained from the collected data,the simulation site of Chengdu Garbage Disposal Industrial Park was successfully realized.And the results of the location of the location are satisfactory.In the conclusion and prospect of the paper,the main innovation of this paper is to improve the traditional site selection system,which has a certain degree of comprehensiveness and operability,which is of practical significance to the study of the site selection of follow-up waste treatment industry park.However,due to lack of data and other reasons,we need to continue in the future research in-depth study.
