新疆乌鲁木齐市地表水资源可利用量分析

摘要

For studying of Urumqi water management three red line, the 5 major river systems in Urumqi city as the re-search object, the surface water resources in an area can be analyzed by quantity. Based on the runoff depth isoline map esti-mate obtained may not be using the water. The percentage methods were used for nearly 10 years minimum monthly runoff law, guarantee rate as the minimum monthly runoff was 90%, the minimum water requirement of different ecological vegetation and ecological environment of lakes, wetlands are calculated; years average evaporation water consumption and the lake, wetland direct precipitation recharge Lake wetland water demand, as follows. Put forward Urumqi surface water resources available quantity is 6. 911 × 108 m3.%为研究乌鲁木齐市水资源管理三条红线，以乌鲁木齐市5大水系为研究对象，对区域地表水资源可利用量进行分析。根据径流深等值线图量算得到不可能被利用水量；分别采用百分数法、近10年最小月径流量法、保证率为90%的最小月径流量法，计算不同生态植被和生态环境的最小需水量；湖泊、湿地多年平均蒸发耗水量与湖泊、湿地直接降水补给量差值作为湖泊、湿地需水量。得出乌鲁木齐市地表水资源可利用量为6.911×108 m3。
