海南省2003年生态足迹计算与发展能力分析

利用生态足迹与发展能力的基本理论,对海南省和各县(市)2003年的生态足迹与发展能力进行了计算和分析。结果表明,海南省2003年人均生态足迹为2.1338hm2,人均生态承载力为1.3111hm2,人均生态赤字为0.8227hm2;12个县(市)存在生态赤字。海南省及其大多数县市的资源利用效益比较低,经济社会发展在较大的生态压力下运行。同时,计算与分析了海南省和各县(市)2003年的生态足迹多样性及其发展能力。

Ecological Footprint Calculation and Development Capacity Analysis in Hainan Province in 2003

The paper briefly introduced the theories and method of ecological footprint and development capacity,and then calculated and analyzed ecological footprint and development capacity in the whole Hainan Province and its counties in 2003.The result shows that per capita ecological footprint was 2.1338hm2,per capita ecological carrying capability was 1.3111hm2,per capita ecological deficit was 0.8227hm2,and 12 counties were in ecological deficits and 6 counties were in ecological surplus.The efficiency of resource utilization in Hainan was still low.The development was under a bigger ecological pressure state.At the same time,the paper calculated and analyzed the ecological footprint's diversity and the development capacity.Ulanowicz,s development capacity was a good predictor of economic system output.Increasing ecological footprint's diversity is a good way to increase resources utilization efficiency and to increase development capacity.At the last,the article puts forward the strategies to achieve sustainable development in Hainan.
