摘　　要：乡村聚落人地系统协调发展是三峡库区乡村可持续发展的重要保障。以重庆三峡库区各县域的乡村聚落人地系统为研究对象,选取影响乡村聚落人地系统发展的包括资源、环境、经济、人口、社会五个方面的20个指标,构建了重庆三峡库区乡村聚落人地系统综合发展水平的时序指标体系,采用全局主成分分析法,定量分析库区乡村聚落人地系统综合发展水平;并引入两系统之间发展协调度模型,对重庆三峡库区乡村聚落人地系统协调性进行评价。结果表明:(1)重庆三峡库区乡村聚落人地系统综合发展水平总体是不断提高的,但县域之间差距较大,经济社会发展水平高的主城各区其乡村聚落人地系统发展速度及综合发展水平高于经济社会发展水平较低的库区下属各区县;(2)重庆三峡库区乡村聚落人地系统正向总体协调的方向发展,自然环境条件较好、社会经济发展水平高的主城各区其乡村聚落人地系统协调度也相对较高,而库区下属各区县由于乡村自然环境较脆弱、社会经济发展水平较低,其乡村聚落人地系统协调度也相对较低。Coordinated development of man-land system of rural settlements is the important way for sustainable de- velopment of rural settlements in the Three Gorges Reservoir. Man-land system of rural settlements in the Three Gorges Reservoir of Chongqing was selected as the study site, 20 indicators affecting man-land system development was selected to construct time sequence index system of comprehensive developmental level of man-land system to make a quantitative analysis on the system in the Three Gorges Reservoir of Chongqing by applying the generalized principle component analysis. And the introduction of coordination degree model of the development between the two systems was used to evaluate man-land system coordination of rural settlements in the Three Gorges Reservoir of Chongqing. The results are shown as follows. （1） The overall developmental level of man-land system of ru- ral settlements in the Three Gorges Reservoir of Chongqing has gained a continuous improvement, but the gap between the counties is larger, the overall developmental level of man-land system of rural settlements and the comprehensive development level of the urban districts with the high level of economic and social de- velopment are higher than the subordinate districts and counties with low level of economic and social devel- opment. （2） The man-land system of rural settlements in the Three Gorges Reservoir of Chongqing presents a state of coordinated development, the downtown districts whose natural environment condition is good, and 1he social and economic development level are high, gaining the high level of the man-land system. However, the level of the man-land system of the rural subordinate districts and counties are relatively low because of their poor environment and low-level economic development.
