摘要
以生态足迹原理为基础,计算了上海市1985-2008年可更新资源的生态足迹和生态承载力,并用生态压力指数及其指数等级划分标准对其进行了生态安全评价。结果显示,近24 a来上海市的自然生态处于极不安全的状态,但是,生态压力指数呈明显下降趋势,上海市还须进一步采取措施减少人口对自然生态的压力。
Based on the principle of ecological footprint,this paper calculates the renewable resources ecological footprint and ecological capacity in Shanghai from 1985 to 2008.And the ecological tension index and rank partition standard are used to measure ecological safety of Shanghai.The result shows that the nature and ecological aren＇t very safety during 24 years,but the ecological tension index is descending clearly.The government must go step further to carry out measures to reduce the ecological tension.
