基于GIS-AHP的乡村居民点空间结构优化研究

Spatial Structure Optimization of Rural Residential Areas Based on GIS-AHP

当前我国乡村出现日趋严峻的“乡村病”,而加快进行乡村规划建设,优化乡村空间结构成为重要任务。基于GIS-AHP方法,构建了乡村空间结构优化的交通便捷因素、环境适宜因素、乡村氛围因素、乡村地形因素4个二级指标因素;用AHP计算出指标的权重和子权重;用地理信息系统的GIS的缓冲区技术,分析了各个影响因素的缓冲区;并用栅格叠加技术,计算和显示出优化后的乡村空间区域。这给我国乡村空间结构优化提供了参考方法。

At present,there is an increasingly serious"rural disease"in China's rural areas.It is an important task to speed up the rural planning and construction and optimize the rural spatial structure.Based on the method of GIS-AHP,four secondary index factors for rural spatial structure optimization were set up,in terms of traffic convenience factor,environmental suitability factor,rural atmosphere factor and rural terrain factor.The weight and sub weight of the index was calculated with AHP.The buffer zone of each influencing factor was analyzed with GIS buffer zone technology.The best Rural space area after transformation was calculated and displayed with grid superposition technology.This provides a reference method for the optimization of rural spatial structure in China.
