笔者从用水定额、可供水量和需水量等方面对该项目区水量供需平衡进行了分析,支渠改建后,不仅解决了之前其渗漏严重、渠系水利用系数低、断面不规则、输水效率低下、过流能力不足、渠系建筑物未配套致使项目区生态林不能有效灌溉等突出问题,而且还具有显著的经济效益和长远的社会效益。希望对同类工程起到借鉴作用。
The author analyzes the water supply and demand balance of this project area from the aspects of water quota, water supply and water requirement. After the branch canal reconstruction, not only has it solved the problems of serious seepage, low water utilization coefficient, irregular cross section, Inefficient overcurrent capacity, inadequate overcurrent capacity and unbalanced canal buildings, which can not effectively irrigate the ecological forest in the project area, but also has significant economic benefits and long-term social benefits. Hope that similar projects play a reference role.
