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.
