渠道防渗是我国目前使用最广泛的节水工程措施,它可以极大地减少农业灌溉用水的浪费,节水潜力巨大。用渠道防渗技术后,可以极大地提高灌溉渠系水利用系数,缓解农业用水供需矛盾,可以防止渠道冲刷、淤积及坍塌,节约运行管理费用,有利于灌区的管理。可以降低地下水位,防止土壤盐碱化及沼泽化,有利于生态环境和农业现代化建设。
Channel seepage control is currently the most widely used water conservancy project in our country. It can greatly reduce the waste of agricultural irrigation water, and has great potential for water saving. With channel seepage control technology, can greatly improve the irrigation canal system of water utilization coefficient, ease the contradiction between supply and demand of agricultural water, to prevent channel erosion, siltation and collapse, save operation and management costs, is conducive to the management of irrigation areas. Can reduce the water table to prevent soil salinization and marsh, is conducive to ecological environment and agricultural modernization.
