【摘要】 以具土石山区典型特征的驿马图地区为对象,在ArcGIS平台下,使用多指标综合评价法结合层次分析法,研究了土石山区人居环境适宜性分布规律及其评价体系。结果表明:驿马图居民点在高程为1 060~1 200 m、坡度为0~15°、坡向为平地或东南方向、距离道路为200 m的范围内的分布最多,其分布指数也处于优势区间,而居民点受河流的影响并不明显。结论:本研究所用评价指标体系适用于土石山区的人居环境适宜性评价,土石山区适宜建造居民点的区域主要集中在河流两旁一定距离的低海拔、低坡度地区,而不适宜居住区主要集中在远离交通的高海拔区域。更多还原

【Abstract】 The Yimatu district which had the typical features of earth-rock mountain regions was chosen as the research object. On the platform of ArcGIS,the multi-index comprehensive evaluation method and the analytic Hierarchy Process were adopted. The distribution regularity of suitability and the evaluation system for the living environment of earth-rock mountain regions were studied. The results were as follows: the distribution of residential areas centers on the areas with an altitude of 1 060 to 1 200 m,the gradient of 0 to 15°,the exposure towards the flat land or towards southeast,and about 200 m from the roads. The distribution index was also between the advantageous intervals. The impact of rivers on residents was unapparent. Conclusion: the evaluation system adopted in this research was applicable to the evaluation on the suitability of the living environment of the earth-rock mountain regions. The residential areas center on the regions near the river,which had low altitude and low exposure. Yet the areas which were not suitable for living were mainly distributed in high-altitude regions with inconvenient traffic.更多还原
