北安市地处乌裕尔河上游,城区供水不足,沿河低洼地水田开发无水源,防洪无保障,黑土地水土流失加剧,制约了城乡经济的可持续发展.新建闹龙河水库,扩建东胜灌区和先锋水库,纳入乌裕尔河流域国家重点水土保持项目,综合治理联合运用,可解决城区供水、开发大面积的水田、有利城乡防洪和生态环境改善. Bei’An City is located in the upper reaches of Wuyuer River with insufficient water supply in urban areas, no water source in paddy fields along low reaches of the river, no guarantee of flood control, and aggravated soil and water loss in black soil, restricting the sustainable development of urban and rural economy. Dongsheng Irrigation and Pioneer Reservoirs are included in the national key water and soil conservation projects in the Wuyuer River Basin. Comprehensive utilization of water and water resources in urban areas can be solved and large-scale paddy fields can be developed to benefit urban and rural flood control and ecological environment improvement.
