以汾河流域为研究区,选取影响区域人居环境适宜性的地形、气候、植被、水文、交通和GDP作为评价指标。基于GIS空间分析平台,构建汾河流域人居环境适宜性评价模型,揭示汾河流域人居环境适宜性分区及空间差异特征。研究表明: 1)汾河流域人居环境适宜性指数位于29.98~ 79.7之间,均值为52.5,整体上从南向北,从河谷盆地向山地丘陵适宜性逐渐降低;适宜和较适宜区占汾河流域总面积的36%,人口约占总人口的55%;一般适宜区面积最大,约占49%,人口约占38.39%;临界适宜和不适宜区比率最小; 2)不同地区人居环境主导制约因素不同。汾河流域人居环境适宜性较高的盆地谷地地区,植被指数和水文条件是其主要制约因子...

The land surface,climate,vegetation,hydrology,transportation and GDP were selected as evaluation indexes,and the human settlements environment suitability evaluation model was set up to reveal the environment suitability regionalization and spatial difference characteristic of human settlements in Fen river basin based on GIS spatial analysis platform. The results showed that: (1) The human settlement suitability decreased from south to north,from basin valley to mountains and hills. The proportion of suitable region and comparatively suitable region accounted for 36% the total region,and the ...
