【摘要】 正确评价土地利用生态经济效益是土地管理决策的重要前提之一。本研究把能值理论与土地利用生态经济效益评价二者紧密结合,并对现阶段农用地转为建设用地时土壤能值的损失未计入能值分析的缺陷进行了改进。在此基础上,选取能值产出/投入、能值密度、土地环境负载指数、可持续发展指数等指标对1999～2004年杭州市土地利用进行了能值效益评价。研究结论表明:(1)杭州市的能值投入中,劳动力与不可更新资源的投入所占比重最高,不可更新资源能值的投入主要是以土地的投入为主;(2)建设用地的能值产出比重大于农业用地,与杭州近年社会经济发展的实际情况相吻合;(3)杭州市土地生态经济系统的能值密度、人均能值等指标高于浙江省与其他省市、发达国家的平均水平,表明土地利用强度较高、人均生活水平富足。最后,对研究的不足进行了初步展望。更多还原

【Abstract】 Correctly evaluation on the benefits of land use eco-economic plays an important role in the land management.This research tried to apply Emergy theory in the land use evaluation on eco-economic benefits.Then the indicators of output/input,emergy density,environment load and sustainable development were selected to evaluated the land use eco-economic benefits in Hangzhou from 1999 to 2004.Results showed that:(1) the input of labor and renewable resource took the highest proportion;(2) the emergy output of construction land is greater than agricultural land,which matches the Hangzhou’s socio-economic development in recent years;(3)the indicators such as emergy density,per capita emergy in Hangzhou were higher than that of Zhejiang province and other provinces and the average level of developed countries,showing the greater intensity of land use and better life standard.Finally,the drawbacks of this research were also discussed preliminary.更多还原
