Problems solved by technology

[0003] The traditional selection of resettlement areas mainly relies on paper materials, field surveys, subjective opinions of experts, and resettlement wishes, etc. These decision-making methods have many disadvantages, such as long time-consuming, limited experts' personal level, subjective influence, etc.
The site selection of immigrant resettlement areas has obvious spatial characteristics related to geographical location, and it is very difficult to describe the spatial characteristics of traditional subjective decision-making site selection

Embodiment

[0100] (1) Generate a candidate set of resettlement areas

[0101] Taking the resettlement of V village, C Township, Zhong T County, a hydropower station in Yunnan Province as an example, first obtain / prepare various types of graphic data, such as the submerged area layer, T County 1:2000 topographic map, land use planning map, road Traffic maps, administrative division maps, bad geological area maps, and other related vector data are filtered through spatial analysis and calculation to filter out slopes that are suitable for living and living of immigrants, non-geological disaster areas, areas with abundant available land resources, and non-policy-restricted areas, etc. Unsuitable areas, areas within 1km away from the water source, 2km away from the main road, and 1km away from the existing settlements, so that a candidate set of resettlement areas is obtained that avoids all spatially unsuitable areas and has suitable slope characteristics , the area of ​​the resettlement ar...

Abstract

The invention discloses a site selection method for immigrant settlement areas based on a geographic information system. The method comprises the following steps of: 1) by using a spatial analysis technology, which comprises terrain analysis, buffer area analysis and superposition analysis, of the geographic information system, establishing a spatial site selection model, and thus obtaining a series of candidate points / areas; 2) establishing an evaluation index system of settlement areas, acquiring each index data of the candidate settlement areas, and entering a database; 3) performing dimensionless standardization on an original matrix of each evaluation index of the candidate settlement areas; 4) determining the weight of each evaluation index by using a composite even weighting method based on an information entropy theory; and 5) based on a fuzzy mathematical theory, performing quality sequencing on the candidate settlement areas by using a fuzzy adjacency ratio method. The method has an important practical application value in the site selection of the immigrant settlement areas of water and electricity engineering and has wider application prospect.

Description

technical field [0001] The invention relates to the technical field of geographic information system technology and multi-objective decision-making theory in the resettlement management of hydropower projects, in particular to a method for selecting resettlement areas. Background technique [0002] Hydropower project resettlement involves many aspects such as society, economy, politics, culture, population, resources, environment, nationality, engineering technology, etc. It is a huge and complex systematic project. Due to the large scope of resettlement and the large number of people involved in hydropower projects, the resettlement work is very difficult and complicated when dealing with many issues, especially the problem of site selection for resettlement areas. Once the site is not properly selected, it will affect the future life of the resettlers and the society. Harmonious and stable, it is very important to realize scientific resettlement site selection. [0003] T...
