通过综述鄱阳湖区人地关系史3个重要时期"围湖造田"、"退田还湖"及"鄱阳湖生态经济区"人类活动对湖区生态环境的影响及三者的转变过程,探讨了湖区人地关系的转变及其驱动力。结果表明"围湖造田"降低了湖泊、湿地的诸多功能(如调蓄洪水、维持生物多样性、碳汇等),促生了人地之间的紧张关系;"退田还湖"则使湖泊、湿地功能得以逐步恢复,缓和了湖区人地关系,而"鄱阳湖生态经济区"的提出与建设将产生良好的社会、经济与生态效益,把湖区人地关系推向和谐阶段。鄱阳湖区人类活动由"围湖造田"到"退田还湖"的转变是在当地人民对自然灾害的深刻反省与国家政策的双重驱动下实现的,而"鄱阳湖生态经济区"的提出与建设则是人与自然和谐相处的价值观在社会、经济发展中的体现,是当地人民主动建设生态文明和实践科学发展观的典型案例。
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 were 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 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.
