Study on Ecological Elasticity of Hunan Province Based on Land Use Transition
利用2000、2005和2010年的植被净初级生产力和土地利用数据，分析了湖南省生态弹性的时空变化，发现全省生态弹性下降86%，且区域差异明显。
This paper analyzes the resilience of the ecosystem of Hunan Province, using vegetation net primary productivity data and land use data in 2000, 2005 and 2010, which were interpreted from Landsat TM images. Results show that:(1) the total ecological elasticity of Hunan Province in 2000, 2005 and 2010 were 0.16, 0.13 and 0.02 respectively, decreased by 86% during 2000- 2010.(2) the difference of regional ecological elasticity is obvious. In the last decade the ecological elasticity of Western Hunan and Dongting Lake District increased, while that of Chang- ZhuTan City Group and Centrual South Hunan decreased. Finally, some suggestions were put forward aiming at how to enhance the total ecological elasticity of Hunan Province and to improve its ecological environment.
