以耕地可持续利用为切入点，应用基于能值分析的耕地生态足迹改进模型，从“国家公顷”和“省公顷”的角度出发修正浙江省耕地产量因子，在此基础上构建耕地生态可持续利用指数，时间维度上对浙江省2003—2012年耕地可持续利用状况进行动态分析，空间维度上对浙江省2012年11个地级市的耕地可持续利用状况进行空间差异分析。结果表明，2003—2012年浙江省人均耕地生态承载力一直处于较低水平且变化不大；人均耕地生态足迹呈波动下降趋势；10 a间人均生态赤字状况有所缓和，但耕地可持续利用指数基本保持在0?2150～0?2664之间，为中等不可持续利用状态；浙江省各地级市人均耕地生态承载力和人均耕地生态足迹均表现出较强的空间差异性；2012年浙江省各地级市耕地生态供给均为赤字，其中宁波、舟山、绍兴、丽水、台州和金华耕地利用状态为中等不可持续利用，杭州、温州、湖州、衢州和嘉兴为强不可持续利用。

With sustainable utilization of cultivated land as the entry point, a modified cultivated land ecological footprint model based on energy analysis was used to rectify yield factors of the cultivated land in Zhejiang Province from the angle of “national hectare” and “provincial hectare”. On such a basis, temporal dynamic analysis was performed of sustainable utilization of the cultivated land in Zhejiang during the years of 2003-2012, and spatial differentiation analysis was con?ducted of sustainable utilization of the cultivated land in the 11 prefecture?level cities of Zhejiang in 2012. Results show that the ecological carrying capacity of cultivated land per?capita in Zhejiang during the years of 2003-2012 remained quite low and did not vary much;per capita ecological footprint of cultivated land declined while fluctuating;and the ecological deficit per capita was somewhat mitigated during the ten years, but the cultivated land ecological sustainability index re?mained in the range between 0?215 0 and 0?266 4, being at a moderate level of unsustainability. Besides, in 2012, though the 11 cities in Zhejiang Province all incurred large ecological deficits, they varied spatially in per capita ecological carrying capacity and ecological footprint of cultivated land: Ningbo, Zhoushan, Shaoxing, Lishui, Taizhou and Jinhua were rated as moderate in unsustainability while Hangzhou, Wenzhou, Huzhou, Quzhou and Jiaxing were as high in unsus?tainability. These findings may provide some theoretical references and solutions for overall prediction and planning of culti?vated land ecological security and cultivated land sustainable utilization in Zhejiang Province.
