赣抚平原水利建设若干问题的思考

Thinking on water conservation construction works of Ganfu Plain

赣抚平原地区为长江以南最大的引水灌区,效益显著。经过数十年的建设与运行,区内部分整治工程暴露出一些急需解决的问题。在深入分析区内水文情势、防洪设施建设、航运等新变化的基础上,对区内水利整治工程建设进行了深入研究。研究结论认为,原箭江口分蓄洪设施应予废除,改用加高加固后的圩堤代替;象湖蓄滞区可以撤销;废除赣抚航道,通过采砂与疏浚相结合的整治措施,开辟稳定的抚河入鄱阳湖航道。

Ganfu Plain is the largest irrigation area in the south area of the Yangtze River and the benefit is significant. After decades of operation, parts of water conservancy works exposed some urgent problems to be solved. On the basis of the detail analysis on the situation of hydrology regime, flood control facilities, navigation etc. in the region, the reformation and construction of water conservancy works is further studied. The analysis results showed that Jianjiangkou flood diversion facilities should be abolished and replaced by the polder dyke reformation; Xianghu lake flood diversion basin can be canceled, the new stable navigation channel from Fuhe River to Poyang Lake should be constructed through sand mining and dredging.
