Abstract: To optimize land use structure in Zhejiang province, this paper uses carbon footprint model to estimate the carbon footprint level from 2007 to 2016 and applies decoupling and standard ellipse variance to study the carbon emission effect of land use in Zhejiang province. The results show a growth rate of 4.06% in net carbon emission in Zhejiang province from 2007 to 2016, most from construction land use. Gap between carbon source and carbon sink is enlarging, making low carbon development difficult. Ningbo city ranks the top in net carbon emission, and Lishui city, which is the only city of carbon sink more than carbon source, is at the bottom. The gap of carbon emission in northeast and southwest Zhejiang province is increasing. The GDP per capita in Zhejiang province is of weak decoupling with carbon footprint per capita, with economic development faster than carbon emission rising rate. Lishui is the best and Zhoushan is poor in decoupling. The spatial distribution of net carbon emission and construction land carbon emission is concentrated in northeast Zhejiang province. The farmland carbon emission is sparsely distributed with the center in the southwest.

Key words: land use, carbon emission, carbon footprint, decoupling index, Zhejiang province

摘要: 为了优化浙江省土地利用结构,在经济发展的同时应做好减排工作。以浙江省为研究区域,利用碳足迹计算模型核算2007—2016年该地区碳足迹水平,利用脱钩分析和标准椭圆差探究浙江省土地利用碳排放效应。研究表明:2007—2016年浙江省年均净碳排放量增长率为4.06%,建设用地是浙江省主要碳源,碳源碳汇总量差距扩大,低碳发展难度加大;宁波市净碳排放量位居浙江省首位,丽水市净碳排放量最低,且是唯一碳汇作用大于碳源的地区,浙东北与浙西南碳排放差距扩大;浙江省人均GDP与人均碳足迹呈现弱脱钩状态,浙江省经济发展快于碳排放量增加速度,丽水市脱钩程度最优,舟山市脱钩程度较差;浙江省净碳排放量与建设用地碳排放量空间分布集聚于东北部,耕地碳排放量空间分布较为分散,较前两者中心偏西南方。
