Study of ecological capacity change and quantitative analysis of ecological compensation in a nature reserve based on RS and GIS: A case study on Po‐yang Lake Nature Reserve, China

摘要

Abstract To make a dynamic analysis of ecological capacity and a quantitative analysis of ecological compensation, to promote the sustainable development in a nature reserve, and to make Po‐yang Lake Nature Reserve as an example, the authors obtained information on land‐use change in the years 1985, 1995, 2005 in Po‐yang Lake Nature Reserve based on RS and GIS. Ecological capacity was quantified and its development change, spatial characteristics, and the sustainable development status of the nature reserve with ecological deficits and surpluses were analysed. Results show that land use had been stable since the Po‐yang Lake Nature Reserve came into existence. The change compared grassland (increased 15.22%), water body (increased 7.05%) and unused land (decreased 18.19%). The ecological capacity improved from 1985 to 2005 (the per capita ecological capacity from 0.8284 ha to 1.0534 ha). among nine villages and towns in the reserve, the ecological surplus villages and towns were Wucheng, Tiehe and Changyi...
