| 摘 要： | 小流量测验是库姆塔格沙漠资源环境本底调查的重要内容.根据库姆塔格沙漠及周边河流泉水野外水文调查(2007-2009),对9条河流泉水16处断面进行了流量测验,分析小流量测验方法及其误差.调查研究表明:(1)库姆塔格沙漠及其周边溪流和泉水枯季径流小,多数河流不适宜用流速仪法实测流量;(2)用V形薄壁堰进行流量测验,其随机...

| Abstract: | Low flow measurement plays a great role in background investigation in the Kumtag Desert environmental resources.The dry season flow in these smaller rivers is not only the main water resource for wildlife,but also for the focus area of plants distribution.In order to test the reliability and accuracy of a suitable discharge measuring strategy for those streams,experimental investigations have been carried out on the small river in and nearby Kumtag Desert.The flow measurements were conducted on 16 sections... |
