重庆市不同功能区建设用地碳排放的库兹涅茨曲线特征分析
Characteristics of Kuznets curve to the relationship between construction land expansion and carbon emission intensity in different functional areas of Chongqing
摘要
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.关键词
