摘    要:在全球公顷和国家公顷的模型基础上,建立了省公顷生态足迹模型.采用2005年浙江省平均土地单位产量核算了浙江省各地的生态足迹,并与全球公顷和国家公顷法的结果进行了比较分析.从省公顷模型的结果可以看出,浙江省生态足迹达1.18s-nhm2/人(省公顷,记为:s-nhm2),而生物承载力只有0.24s-nhm2/人,生态赤字达0.94s-nhm2/人,生态压力指数达4.91,是典型的生态赤字地区.另外,浙江省各地生态足迹空间差异较大,与全省平均水平相比,舟山和温州处于高强度生态压力,宁波、杭州、台州、金华和绍兴处于中强度生态压力,而丽水、衢州、湖州和嘉兴处于低强度生态压力.最后借助IPAT的分析,发现杭州、金华、嘉兴、湖州和衢州等地的万元GDP占用足迹不同程度地高于全省平均水平,并指出在一定条件下,应结合当地的经济发展程度合理提升资源利用效率的技术水平.

关 键 词:省公顷  生态足迹  空间差异  可持续发展

Abstract:The ecological footprint model on the basis of sub-national hectare was presented in this paper according to the ecological footprint concept and model on the basis of global hectare or national hectare. The ecological footprint and its composition of each city in Zhejiang Province were evaluated and analyzed by using the modified model and the actual yield per unit area of Zhejiang in 2005.The results were compared with those which were evaluated in global hectare or national hectare method, and the differences were analyzed among them. When using sub-national hectare as the evaluation criterion, the ecological footprint, the ecological capacity and the ecological deficit of Zhejiang Province in 2005 would be 1.18s-nhm2/cap, 0.24s-nhm2/cap and 0.94s-nhm2/cap respectively, and the ecological pressure index was 4.91. The results suggest that Zhejiang Province is a representative area that has a large ecological deficit and high ecological pressure. They also suggested that there was a significant spatial difference according to the ecological footprint and its composition among the cities of Zhejiang. Compared with the average level of city ecological footprint in Zhejiang Province, Lishui, Quzhou, Huzhou and Jiaxing were in low ecological pressure states, and Ningbo, Hangzhou, Taizhou, Jinhua and Shaoxing were in middle ecological pressure states, while Zhoushan and Wenzhou were in high ecological pressure states. In the end, by applying IPAT, more eco-footprint demand of 104yuan GDP was found in Hangzhou, Jinhua, Jiaxing, Huzhou and Quzhou, which have a higher level than the average of Zhejiang, and suggestions were proposed that the level of local economic development must be considered to promote resource use efficiency.
Keywords:sub-national hectare  ecological footprint  spatial difference  sustainable development
