摘要

应用生态足迹的方法

从时间序列来研究区域的可持续发展

引入生态压力指数、生态占用指数和生态经济协调指数模型

构建了新的生态安全评价指标体系。以浙江省为例

通过计算人均生态足迹和生态承载力的变化率和剪刀差

对浙江省2000—2006年的生态足迹和生态安全指标体系进行了定量研究。结果表明

浙江省2000—2006年的人均生态足迹与生态承载力呈反向发展趋势

人均生态赤字持续增加;生态压力指数从2000年的2.34增至2006年的3.22

同期的生态占用指数从0.67增至0.90

生态经济协调指数由0.286降低为0.277。说明浙江省现有的可持续发展模式面临严重考验

生态安全的发展趋势不容乐观

社会经济发展与生态环境的承受能力不相协调。

Abstract

The authors apply ecological footprint method to evaluate the sustainable development and ecological security of Zhejiang Province by the time series.The paper constructs the new evaluation index system of ecological security and introduces the model of ecological tension index

ecological occupancy index

and ecological economic coordination index.Taking Zhejiang Province as a case study area

the paper introduces the concepts of change rates and the scissors difference to quantitatively analyze the trends of ecological footprint and index system of ecological security in the province from 2000 to 2006.Results show that the per capita ecological footprint of Zhejiang Province increased reversely with ecological carrying capacity and the per capita ecological deficit increased steadily.Ecological tension index increased from 2.34 in 2000 to 3.22 in 2006.In the same period

ecological occupancy index increased from 0.67 to 0.90 and ecological economic coordination index declined from 0.286 to 0.277.The sustainable development model of Zhejiang Province is not optimistic

its ecological environment is at risk

and its social economic development does not go well with ecological environment.
