自20世纪50年代开始,太湖流域各级政府和民众为抵御洪涝灾害,在农田水利建设过程中进行了联圩并圩,至70年代中后期,联圩工程由低洼地区向半高田地区全面推开。这一时期的联圩并圩不同于80年代后的标准化圩区建设,而具有粗放性的特点,对生态和社会都产生了重要的影响。从积极方面看,联圩内抵制洪水的能力有所增强、农作物产量明显提高;从消极方面看,太湖流域水系蓄泄能力总体下降,水域生态环境遭到一定程度的破坏,部分联圩因施工质量低下和其他原因存在安全隐患,各种水利纠纷与矛盾屡有发生。 Since the 1950s, governments and people at all levels in the Taihu Lake Basin have resisted the floods and waterlogging. During the construction of farmland water conservancy, they carried out a series of levees and weaves together to the mid-to-late 1970s. open. In this period, the joint dike and dike differs from the standard dike construction after the 1980s, and has the characteristics of extensiveness, which have a significant impact on ecology and society. On the positive side, the capability of resisting floods in Lianxu County has been enhanced and the yield of crops increased significantly. From a negative point of view, the storage capacity of water system in the Taihu Lake Basin has generally declined, and the ecological environment in the water area has been damaged to some extent. Low quality and other reasons there is a security risk, a variety of water disputes and contradictions have occurred.
