退田还湖对洞庭湖湿地生境及生物多样性影响数据库（2009-2011）

主要内容为退田还湖模式下洞庭湖湿地2009-2011生境及生物多样性变化等数据资料，包括退田还湖后植被恢复数据；退田还湖土壤理化性质及酶活性数据；退田还湖土壤种子库数据，为研究洞庭湖湿地生境变化及生物多样性功能及其变化提供基础数据支撑。

This dataset mainly includes data on habitat and biodiversity changes in the Dongting Lake Wetland under the returning farmland to lake initiative from 2009 to 2011. Specifically, it covers vegetation restoration data after the returning farmland to lake project, soil physical and chemical properties and enzyme activity data, as well as soil seed bank data associated with the project. This dataset provides fundamental data support for research on habitat changes, biodiversity functions and their variations in the Dongting Lake Wetland.
