摘要
为了在量的特征和人的解决的空间模式探索地理差别，在三的环境适用性( HSES )塞满水库区域( TGRA )，地面，气候，水文学，植被和另外的天赋因素被选择造过得去的环境评估，并且定量分析通过遥感( RS )和地理参考系统( GIS )被进行揭示地理特征和 HSES 的空间模式。结果如下被获得：(1 ) 重庆的 TGRA 的居民与中等高 HSES 在区域被集中，它是在 48% 学习区域散布的 78% 全部的人口；(2 ) HSES 是仔细与地面有关，并且它形成一个弧乐队空间继任模式：在东北和东南相对低当时在西方和南方比较地高；(3 ) 大量人与低适用性在区域被散布(与更高的人口密度比西方的中国的一般水准) ，但是在这些区域的经济发展水平是相当低的。而且，这些区域是生态的敏感、易碎，许多种 eco 环境的问题被人的活动引起了。因此，人口移植和布局是为这些区域的发展的合理选择。
To explore geographical differences in quantitative characteristics and spatial pattern of human settlements environmental suitability （HSES） in the Three Gorges Reservoir Area （TGRA）, terrain, climate, hydrology, vegetation and other natural factors were selected to build the livable environmental evaluation, and the quantitative analysis was conducted through Remote Sensing（RS） and Geographic Informational System （GIS） to reveal geo- graphical characteristics and spatial patterns of HSES. The results are obtained as follows： （1） inhabitants of the TGRA of Chongqing are concentrated in the area with moderate h.igh HSES, which is 78% of the total population distributed in 48% of the study area; （2） the HSES is closely related to the terrain, and it forms an arc-banded spatial succession pattern： relatively low in the northeast and the southeast while comparatively high in the west and the south; （3） large numbers of people are distributed in the area with low suitability （with higher population density than the average of the western China）, but economic development level in these areas is quite low. Moreover, these areas are ecological sensitive and fragile, many kinds of eco-environmental problems have been caused by human activities. Therefore, population migration and layout are reasonable options for the development of these areas.
