摘要:

通过构建人居环境适宜性综合评价指标体系,利用综合评价模型计算克里雅绿洲1995、2005和2015年的人居环境指数,从时空角度分析人居环境适宜性演变情况,定量揭示克里雅绿洲人居环境适宜性的空间格局和地域特征。结果显示,1995-2015年克里雅绿洲人居环境指数总体呈上升趋势,人居环境质量有所改善,比较适宜人类聚居生活的区域面积逐年增加,而临界适宜区和低度适宜区的面积总体上减少,说明沙漠化对绿洲外围交错带的侵蚀现象依然严重。1995-2015年,克里雅绿洲不同人居环境适宜类型之间,尤其是地域上相邻类型之间相互转换的现象十分明显。绿洲内部各类型相对稳定,而绿洲外围各类型之间转换幅度较大。各单项指标与人居环境指数相关性的排序为:距集市距离 > 距水源地距离 > 地被指数 > GDP产值 > 气温 > 降水 > 地形起伏度。人居环境中、高度适宜区主要分布在绿洲中部,靠近集市和交通线的区域,这些区域各指标的适宜程度较高,是人类比较理想的聚居地;不适宜区和临界适宜区主要分布在绿洲外围沙漠及交错带区域,这些区域受各指标条件的严格限制,不适宜人类居住生活;而低度适宜区主要分布在中度适宜区外围的草地区域,人居环境条件较差,人类居住和生活受到一定限制。

Abstract:

By constructing a comprehensive evaluation index system of human settlements suitability and utilizing comprehensive evaluation model to calculate the human settlements environment index of Keriya Oasis in 1995, 2005 and 2015, the evolution of human settlements suitability was analyzed from the space-time perspective and the spatial pattern and geographical characteristics of human settlements suitability were quantitatively revealed. The results show that from 1995 to 2015, the human settlements environment index in Keriya Oasis appeared to be on a rise in general, the quality of human settlements was improved in the period, the area suitable for human settlements increased year by year, while the area of the critical suitable area and the low suitable area were generally decreased. As a whole the erosion of the ecotone on the periphery of the oasis caused by desertification remained serious. From 1995 to 2015, the phenomenon of conversion between various types of human settlements suitability, especially between geographically adjacent types, was quite obvious in Keriya Oasis. Within the oasis, the various types were relatively stable, while on the periphery of the oasis, the conversion extent between various types were comparatively large. Ranking of the correlation between the indicators and the human settlements environment index is distance from the market > distance from water source > land cover index > GDP > temperature > precipitation > relief degree of land surface. The moderately suitable area and the highly suitable area have a high degree of suitability for various indicators, which are mainly distributed in the central part of the oasis, close to the market as well as the traffic lines, and are ideal places for human settlement. The unsuitable area and the critical suitable area are mainly distributed in the desert and ecotone on the periphery of the oasis. These areas are strictly restricted by the conditions of various indicators and are not suitable for human settlement. The low suitable area are mainly distributed in the grassland area on the periphery of the moderately suitable area, which is restricted by the conditions of various indicators. The living conditions of this area are relatively poor and human settlement is subject to certain restrictions.

Key words: human settlements environment index, human settlements suitability, spatial-temporal evolution, dynamic evaluation, Keriya Oasis, Xinjiang
