| 摘 要： | 文章对重庆市五大功能区1998-2013年的土地利用变更数据调查和能源消耗数据进行分析，运用库兹涅茨曲线模型研究了重庆市五大功能区16年间建设用地扩张与碳排放效应之间的内在关系。结果表明:（1）重庆市建设用地扩张与碳排放强度之间的回归模型关系呈倒U型库兹涅茨曲线关系，且拐点即将到来；（2）都市功能核心区、都市功能拓展区建设用地与碳排放强度之间的关系呈倒U型库兹涅茨曲线关系；（3）城市发展新区建设用地与碳排放强度之间的关系呈一次线性关系，显示出区域产业结构调整和土地利用集约水平的初级特征；（4）渝东北生态涵养区建设用地与碳排放强度之间呈正U型二次曲线关系，土地集约利用水平亟待提高。

| Abstract: | Chongqing is situated in the upper stream of Yangtze River and lies in the southeast of Sichuan Basin, southwest of China. In September 2013,Chongqing has been divided into five metro-functional areas in the third plenum of the fourth Committee, which is closely related to the economic development of Chongqing. Studying the relationship between construction land expansion and carbon emission can provide some scientific evidences for the optimization of land resources allocation, industrial restructuring and sustainable development. It analysed the relationship between construction land expansion and carbon emission from 1998 to 2013 by using Kuznets curve fitting technology. Results show that ,(1) In Chongqing, the Kuznets curve of the construction land expansion and carbon emission intensity generally presents an inverted U-shape relation, which shows that current Chongqing is quite close to the flex point in terms of urban economic development; (2) The Kuznets curve in core area of urban function and developing area of urban function shows an inverted U-shape relation; (3) The Kuznets curve in the newly developed district shows single linear relationship, which implies the primary features of regional industrial structure adjustment and the intensity level of land utilization; (4) The Kuznets curve in biological conservation area of the northeast Chongqing shows a U-shape quadratic curve indicating the relationship between construction land expansion and carbon emission intensity and the intensity level of land utilization remains to be improved. |
