中文摘要	该文以开孔河流域为研究区,选择地形地貌、气候、水文、植被、土地利用/土地覆盖等自然生态环境因子,运用3S技术,在1 km*1 km的栅格尺度上,进行投影转换、遥感解译、信息提取与分析,定量定性地反映了开孔河流域人居环境适宜性的空间规模与分布特征。结果表明:1)开孔河流域的人居环境指数介于4.4~83.9之间,人居环境适宜性从研究区中部平原区向西北天山高山区和东南塔克拉玛干沙漠区逐渐递减,研究区内大部分地区的人类生产活动受到自然条件的约束与限制。2)根据适宜性指数的大小整个开孔河流域可分为高适宜区、适宜区、一般适宜区、不适宜区以及最不适宜区5个区域,其面积分别为124、2 456、2 526、23 104、46 301 km~2,分别占全研究区面积的0.2%、3.3%、3.4%、31%、62.1%。3)高适宜区、适宜区与一般适宜区的面积总和占整个研究区总面积的6.9%,而研究区总人口的98.8%居住在这6.9%区域内。不适宜区与最不适宜区面积总和占研究区总面积的93.1%,总人口的1.2%分布在这93.1%的区域内。研究结果表明,开孔河流域自然环境极其恶劣,生态环境质量相当脆弱,大部分地区受到自然环境条件的制约。所以在今后的发展规划当中需要结合当地自然环境情况与自然资源承载力,合理的进行城市规划与新农村建设。
英文摘要	With the rapid economic and social development, more and more concerns are on the survival of their own settlement environment. Human settlement environment is not only the basic space of human existence and activities, but also the concentrated expression of human civilization. In this paper, the Human Settlements Environment Index (HEI) model was built to evaluate the environmental suitability for human settlements in Kai-Kong River Basin, using the selected relief degree index, vegetation index, humidity index, hydrology index, and land use evaluation index, with the grid scale of 1 km*1 km. Through applying spatial analysis technique of ArcGIS software including spatial overlay analysis and density analysis,the spatial situation of human settlement environment suitability and spatial pattern for human living environment in Kai-Kong River Basin were systematically summarized and established.The results showed that the index of nature suitability for human settlement in the Kai-Kong River Basin was between 4.4 and 83.9. According to the correlation between the human distribution and the human environment index the human settlement environment in Kai-Kong river divided into five region, they are high suitable region, suitable region, general suitable region, unsuitable region and least suitable region. In general, suitability for human living environment decreased from middle plain areas to Tianshan mountain areas in the northwest and Taklimakan desert areas in the southeast.In the study area,the high suitable region was mainly distributed in Korla city, which accounted for about 124 km~2, 0.2% of the total area of the study region. Suitable region was mainly distributed in bordering area of Bohu, Hejing, Heshuo, Yanji and Yuli county, which accounted for about 2 456 km~2, 3.3% of the total area of the study region. General suitable region was mainly distributed in around the suitable region, which accounted for about 2 526 km~2, 3.4% of the total area, this area was mainly located in the intersecting zone, so that it has a great potential for development. The unsuitable region was mainly distributed in upper stream of Kai-Kong River Basin which covered by snow and accounted for about 23 104 km~2, 31% of the total area. The least suitable region was mainly distributed southwest part of the study area, this area was mainly composed by desert that characterized with high temperature, high evaporation, low precipitation and low vegetation cover, not suitable for human living and development, and it constitutes the largest parts of the whole study area, which accounted for about 46 301 km~2, 62.1% of the total area. High Suitable regions and suitable regions for human living were distributed mainly around Kai-Kong River connecting region in the form of ribbons and batches. The high suitable region, suitable region and general suitable region accounted for 6.9% the total area of study region, and 98.8% of the total population in this area. Unsuitable region and the least suitable region accounts for 93.1% of the total study area, and only 1.2% of the total population distribution in this region. Results also indicated that the geographical environment of the study area is rather fragile. Therefore, it is not suitable for increasing population and conducting irrational land development activities in the Kai-Kong Rivers Basin. Spatial distribution of population was influenced and controlled by severe environmental conditions, such as the constantly expanding of deserts, the high terrains, and the complicated climate as well as the lack of hydrological conditions. Irrational agricultural production activities and slow economic growth was also the huge obstacles of suitability for human living environment in the Kai-Kong River Basin. According to these problems and various planning,it can be suggested that some of the residential areas are needed to relocate, in order to improve situation of residential environment.
