摘要
为了探究黄泛区农田土壤渍涝障碍的发生机制,通过对区域农田土壤渍涝障碍要素资料收集整理并加以论证分析,研究封丘县域农田土壤渍涝障碍的季际、年际和典型时相的时空动态特征,结合农田土壤渍涝障碍的定位动态监测数据,研究区域农田土壤障碍现状与典型历史时相的时空分布特性,解析农田土壤渍涝障碍的动态演变规律,揭示区域农田土壤渍涝障碍的总体演变规律与趋势。
In order to explore the mechanism of Huangfanqu farmland waterlogging disorder, based on the factors of regional farmland waterlogging disorder data collected and demonstrated analysis, spatial and temporal dynamic characteristics of the research on Fengqiu county farmland waterlog- ging disorder seasonal, interannual and typical, combined with the positioning of the dynamic moni- toring data of farmland soil waterlogging disorder. The spatial and temporal distribution characteris- tics of phase status of regional farmland soil obstacle research and typical historical evolution, dy- namic analysis of soil waterlogging disorder, the overall evolution trend of regional farmland water- logging disorder revealed.
