中文摘要：

基于三峡库区重庆段22个区县19972011年人口和GDP数据，计算各区县的人口地理集中度、经济地理集中度和二者的耦合指数，分析三峡库区重庆段各区县人口和经济集聚特征，人口与经济褐合类型，并在Geoda软件支持下对各区县人口与经济耦合指数进行全局空间自相关分析和局部空间自相关分析。研究结果表明，三峡库区重庆段人口地理集中度和经济地理集中度均呈现出西南高东北低的分布特点；根据人口与经济地理集中度耦合指数将三峡库区重庆段22个区县划分为人口集聚超前于经济集聚、人口集聚与经济集聚协调发展、人口集聚滞后于经济集聚等3种划分类型；全局空间自相关分析表明1997—2011年研究区人口与经济空间耦合具有较高空间集聚特征但呈下降趋势；局域空间自相关分析进一步表明研究区局域集聚程度也较高，并且空间集聚主要分布在重庆主城和研究区东北部。重庆主城由于地理位置优越，交通便捷，故而经济发展水平较高且人口集聚程度高；研究区东北部地理环境较差，交通不便，产业结构单一，故而经济发展水平较低且人口集聚程度低。为了降低三峡库区重庆段人口与经济空间集聚的不均匀程度，建议调整产业政策向研究区东北区域倾斜以促进当地产业经济发展和人口的回流；并且研究区东北区域也应抓住自身优势大力发展优势产业。同时还可采取改善重庆主城至研究区东北区域的交通条件等措施。

英文摘要：

Based on the population and GDP data of 22 counties of the Three Gorges Reservoir in Chongqing region in 1997-2011, this paper computed and analyzed the geographic concentration of population and economic, their coupling indexes, and with the support of Geoda software, the global and local spatial autocorretation analysis of coupling indexes of population and economic was carried out among 22 counties. The results showed that： 1） the distribution of population and economic are disequilibrium, namely, that in southwest is higher than that in northeast; 2） according to the coupling indexes, among 22 counties of the Three Gorges Reservoir in Chongqing region, there are three types in the relationship between the population and economic development in this re- gion, namely, population concentration advanced of economic concentration, population concentration harmonized with economic concentration, population concentration lagged behind of economic concentration; 3） the global autocorrelation analysis demonstra- ted that spatial coupling between population and economic was highly agglomerated but showed a downtrend; 4） local spatial auto- correlation analysis showed that there was a high degree of local agglomeration, especially at main urban zone of Chongqing city and the northeast study area. The possible reason is that main urban zone of Chongqing city enjoys good geographical location and con- venient transportation, thus possessing high level of economic development and high degree of population concentration; on the con- trary, its poor geographical environment, inconvenient transportation and single industrial structure at northeast study area making low level of economic development and population concentration. In order to bring down the uneven degree of the geographic concen- tration of population and economic in Three Gorges Reservoir in Chongqing region, advice to adjust industrial policy toward the northeast study area to promote the local economic development and the population of backflow; bes
