一直以来我国农村居民点布局缺乏统一规划,土地的适宜性未进行过量化分析。基于GIS的技术平台,采用层次分析法(AHP)计算相关影响因子权重,叠加分析后将居民点用地分成四类,对溆浦县桥江镇农村居民点适宜性进行评价。通过具体的运算结果,较好地描述农村居民点斑块的用地规模、形状和分布状况,更直观地反映居民点的散布情况,为今后村庄规划中居民点的规划布局提供可靠的研究依据。
All along, the layout of rural residential areas in China lacks unified planning and the suitability of the land has not been quantitatively analyzed. Based on the GIS technology platform, AHP is used to calculate the weight of the relevant factors, and after the overlay analysis, the residential land is divided into four categories to evaluate the suitability of rural settlements in Qiaojiang Town, Xupu County. Through the specific operation results, the size, shape and distribution of land for rural residential land patches can be well described, and the distribution of residential areas can be more directly reflected, which can provide a reliable basis for the future planning and layout of settlements in village planning.
