【摘要】 灌区工程长期运行后,其内部渠系建筑物退化、老化,灌溉水有效利用系数下降,工程效益得不到充分发挥,下游灌区农作物大面积减产,严重影响灌区经济的发展。本文以山东省宁阳县东引汶灌区工程为例,深入分析了灌区渠系建筑物病害、老化问题,并结合当地实际条件,从灌区水利工程维护、灌区信息化建设、灌区管理模式等方面给出相关发展策略,以期改善和提高灌区渠系建筑物的耐久性,为其他灌区工程正常发挥作用提供借鉴与参考。更多还原

【Abstract】 After long-term operation of irrigation area projects, the internal canal system buildings are degraded and aged, the effective utilization coefficient of irrigation water is reduced, the project benefits are not fully brought into play, and the crop production in the downstream irrigation area is greatly reduced, which seriously affects the economic development of irrigation area. Taking the project of Dongyinwen Irrigation District in Ningyang County of Shandong Province as example, this paper deeply analyzed the problems of disease and aging of canal system buildings in the irrigation district, combined with the actual local conditions, and proposed relevant development strategies from the aspects of water conservancy project maintenance, information construction and management mode in the irrigation district, so as to improve and enhance the durability of canal system buildings in the irrigation district. It provides reference for other irrigation projects to play a normal role.更多还原
