摘要： 为优化农村居民点布局,促进城乡协调发展,运用层次分析法对农村居民点适宜性进行评价。选取西北地区地貌类型多样、地形破碎复杂的陇县作为研究区,基于县域特点和农村居民点用地特征,从自然因素和社会经济因素两个方面确定评价指标。将高程、坡度、坡向、水源影响度作为自然要素评价指标,将道路通达度、城镇中心可达性、用地规模作为社会经济要素评价指标,在ArcGIS 10.3软件支持下,利用多层分析加权求和的方法,以20 m×20 m的栅格像元大小作为评价单元,对陇县农村居民点进行多因素综合评价。将用地适宜性划分为适宜、较适宜、基本适宜和不适宜4个等级,分别占用地总规模的13.88%、42.84%、34.48%、8.80%。结果表明,适宜农村居民点用地自然条件优越,交通便捷,距离城镇中心较近且用地规模大,适合设施建设需要；较适宜农村居民点用地分布广泛,地势略有起伏,交通方便,城镇中心可达性较高且具有一定的规模；基本适宜农村居民点用地自然条件略差,道路通达度一般,城镇中心可达性和用地规模有限制；不适宜农村居民点用地地形条件差,交通不便,距离城镇中心远且多为零碎地块,不利于居民点发展。研究结果为农村居民点用地选择提供了理论基础。

Abstract: To optimize the layout of rural residential areas and promote the coordinated development of urban and rural areas, the Analytic Hierarchy Process (AHP) was used to evaluate the suitability of rural residential areas. Selecting Longxian in northwestern region as the research area, which had various landform types and complicated terrain, and based on the features of the county and the characteristics of rural residential land use, the evaluation indexes were determined from two aspects of natural factors and social economic factors. The elevation, slope, slope direction and water source influence were evaluated as natural factors, and the accessibility of roads, the accessibility of urban centers and the scale of land use were as socio-economic factors. With ArcGIS 10.3 software support, using the method of AHP, and taking the grid of 20 m×20 m as the evaluation unit, multi- factor comprehensive evaluation was used to estimate rural residential areas in Longxian. The results of suitability evaluation of residential land was graded into four classes of optimal, suitable, basically suitable and unsuitable, accounting for 13.88%, 42.84%, 34.48% and 8.80%, respectively. Optimal rural residential area had superior natural condition and convenient transportation, was close to the town center and large scale of land, and was suitable for the construction of facilities. Suitable rural residential area had wide distribution of land, slight fluctuation of terrain, convenient transportation, high accessibility of urban centers and a certain scale. Basically suitable rural residential area had slightly poor natural condition, and general accessibility of roads, and limited accessibility of urban centers and the scale of land use. Unsuitable rural residential area had poor topographic condition and inconvenient transportation, far from the center of the town in scattered plot, and it is not conducive to the development of residential areas. The results provide a theoretical basis for the selection of rural residential land.
