广东省不同土地利用方式与碳排放规律分析
P934; 探讨了广东省1996-2008年不同土地利用方式的碳排放量及时空变化规律.结果表明:在时间序列上,建设用地的碳排放量变化趋势明显,耕地、草地碳排放变化量不明显,林地变化引起的碳排放量增加,增加量近两年得到有效控制;在空间序列上,不同土地利用方式产生的碳排放情况呈明显的区域差异;碳排放量的变化与区域经济发展特征存在时空耦合规律.在此基础上,从低碳经济的发展角度提出土地利用的相关政策建议....

| Bibliography: | 44-1267/S land use; carbon emission; Guangdong Carbon emission and spatial distribution rules of different land use patterns were studied in Guangdong province from 1996 to 2008.The results indicated that,in the time series,carbon emission of construction land increased significantly,carbon emission of farmland and grass land changed not very significantly,the increasing of forest land enhanced the carbon emission which was effective controlled.While in the spatial series,there existed obvious region differences caused by different land use patterns,and there existed a space and time coupling rule between carbon emission change and regional economy development.Based on this,the of land use policy proposal of low-carbon economy were put forward.
