GIS macro-micro decision support system for site selection of water plant in remote area

Abstract

According to the remote area water plant site selection GIS macro-micro decision support system, macro and micro processes of remote area water plant site selection are respectively and deeply analyzed, the macro process determines a water plant alternative area, and the micro process obtains an optimal construction position of a water plant by constructing a water plant optimal position calculation selection model in the determined alternative area. The invention provides specific implementation of a remote area water plant site selection GIS macro-micro decision support process; a remote area water plant site selection macro-micro decision support system is designed on the basis of a remote area water management information system serving as a platform. The system adopts a more scientific and reasonable method to comprehensively consider various factors to determine the optimal position of the water plant, a very good effect is achieved, the scientific meticulous property, comprehensive comprehensiveness, convenience and practicability of site selection are not possessed by the prior art. The system has very strong expandability, very high practical value and wide application prospects.

Description

technical field [0001] The invention relates to a GIS decision support system for water plant site selection, in particular to a GIS macro and micro decision support system for water plant site selection in remote areas, and belongs to the technical field of water plant site selection decision support. Background technique [0002] In remote areas, due to the imperfect construction of water supply facilities and the aging of the previous water supply equipment, many places still have not completely solved the problem of water use. Reasonably determine the construction location of water plants. Water plants are the core of water use projects in remote areas. The location of water plants directly determines the coverage and construction costs of water plants, and even affects the planning of new water plants in the region in the future. The site selection of a water plant involves many aspects such as the selection of water sources, the determination of water supply areas, and...

Problems solved by technology

[0014] Aiming at the deficiencies of the existing technology, the present invention is specially aimed at the site selection of water plants in remote areas, and proposes a specific model to solve the problem of water plant site selection, and fully combines GIS tools to explore large-scale water plant site selection, overcoming the traditional Based on the existing problems of the site models, GIS is organically combined with other site selection models. The present invention is dedicated to the site selection of professional water plants. According to the determined site selection influencing factors, a set of water plant site selection schemes is designed, and finally the scheme Applied in the decision-making system for water plant site selection, the optimal location of the water plant is determined according to the decision parameters input by the user. Considering comprehensively that the site selection involves water source selection, water supply area, pipeline laying and other aspects, it has successfully solved the problem. The comprehensive and complex problem of water plant site selection
