中文摘要	适宜的人居环境对促进人类社会经济系统与自然生态系统协调发展具有重要意义。以30 m*30 m的栅格为基本单元,运用RS和GIS技术,对原始影像数据进行解译、提取、运算和分析,结合研究区的实际情况,得到宁夏中部干旱带人居环境生态适宜性模型(HEI),并对适宜性的空间分异特征进行初步评价。结果表明:1宁夏中部干旱带人居环境适宜性指数介于16.05~84.90之间,整体生态适宜性较高。空间格局表现为:除东北角少数乡镇外,从西南方向到东北方向适宜性逐渐提高,从南到北适宜性逐渐提高。2研究区发展受水资源限制较大,适宜性地区沿灌渠和水系呈带状分布。高度适宜区占7.64%,较适宜区占11.49%,一般适宜区占27.42%,临界适宜和不适宜区占研究区总面积的53.45%。通过对宁夏中部干旱带人居环境生态适宜性评价,以期为宁夏境内生态移民区选址和生态环境保护提供数据支撑。
英文摘要	Suitable human settlement environment plays an important role in promoting the harmonious development between social-economic systems of human society and natural ecosystems.In this study,a human settlement environment index (HEI) model for central arid zone in Ningxia was developed based on the grids of 30 m * 30 m, RS and GIS means and local conditions by interpreting,extracting,calculating and analyzing the original image data, and the spatial distribution patterns of ecological suitability were assessed.The results are as follows: ① The HEI varied in a range of 16.05 - 84.90,and it was holistically high.The HEI of central arid zone in Ningxia was increased from the southeast to the northwest and from the south to the north; ② The suitable settlement areas were distributed along the irrigation and stream systems.The proportions of areas with the highest,high and moderate ecological suitability for human settlement were 7.64%,11.49% and 27.42% respectively,and the proportion of areas with poor and extremely poor ecological suitability was 53.45%.The study results may provide the data support and basis for choosing the ecological immigration sites and ecological environment preservation in Ningxia.
