低碳城市已成为全球城市发展的重要导向坐标,城镇建设用地作为城市碳排放的主要来源,分析城市用地空间扩张与碳排放的相关效应,对合理规划城镇建设用地,促进低碳城市建设具有重要意义.本文以长沙市为研究对象,分析了长沙城市用地空间扩张特征与城市碳排放的时空演变特征,测算了城市用地空间扩张速度和碳排放变化速率,利用协同扩张指数计算两个指标的量化关系,得出城市用地空间扩张与碳排放的相关效应.

Low carbon city has become an important oriented coordinate for global city de- velopment. The urban construction land is the main source of city carbon emissions. It has the important meaning to analyse the correlation effect of city land expansion and carbon e- missions for reasonable planning of urban construction land and promoting low-carbon city construction. Taking Changsha City as the research object, it analyses characteristics of city land expansion and carbon emission spatio temporal change, estimates the rate of city land space expansion and rate of change of carbon emission and re...
