Land Use Suitability Evaluation on Spatial Development of the Mountain Towns Based on GIS:A Case Study of Dabu, Guangdong
摘要
Abstract
Land Use Suitability Evaluation is the basis of land-use planning. Due to the particularity of the mountain towns, in this paper the topography factor, ecological sensitivity factor, limiting factor, transportation and urban location factors are selected to make land suitability evaluation for mountain towns’ spatial development. Huliao Town, the county seat of Dabu County, is taken as an example to be studied. Analytic Hierarchy Process(AHP) is used to calculate the weight value for each factor, and the multi factor overlay method is used to calculate the land suitability for town development of each grid. According to the evaluation result, the land of the mountain town is classified into four types:the built-up areas (235.75km2) to be optimized, the areas suitable for construction (352.17km2), the areas limited to construction (1 643.92km2), and the areas banned for construction (218.54km2). The result suggests that the GIS technology could make land suitability evaluation quickly and objectively, which could provide scientific decision support for land-use planning.关键词
