Abstract:

Poyang Lake is the largest fresh lake in China. Poyang lake region has thousands of years of history in manland relations.This study reviewed the three important periods in the history of manland relations in Poyang Lake region,which was “converting lake to farmand” and “returning farmland to lake”,as well as the construction of “Poyang Lake EeoEconomic Region”,respectively.Moreover,the effects of the anthropogenic activities in the three periods on local ecological environments and their mutually conversion processes were analysed.Consequently, the evolvement of manland relations and associated driving force in the Poyang lake region wer〖JP2〗e discussed.Results showed that the human activity of “converting lake to farmland” declined various lake and wetland fuctions such as regulating floodwater,maintaining biodivisity,as well as carbon sinks.Hence,the tensity between human and environments was sharpened.Whereas,“returning farmland to lake” could gradually restore the lake and wetland functions,and released the tensity of manland relation.Furthermore,the construction of “Poyang Lake EeoEconomic Region” will build a harmonious manland relation in Poyang lake region.As a result,the local society,economy and environment will benefit greatly from the project.Changes of the human activities from “converting〖JP〗 lake to farmland” to “returning farmland to lake” were driven by local people’s selfexamination on natural disaster and state policy.However,the implement of “Poyang Lake EeoEconomic Region” was driven by local people and government's own initiatives.It shows their great respect to nature when they develop economies, which is a typical case of ecological civilization construction and development according to scientific law.
