A preliminary study on the alpine vegetaion and the biodiversity in the headwater area of urumqi river in the tianshan mountains .

天山乌鲁木齐河源区高山带植被及其生物多样性初步研究。

Headwater acidification is still a significant problem for important salmon fisheries , and special areas of conservation such as the welsh river wye .

河流源头酸化依然是重要的鲑鱼水产业和特别保护区（例如威尔士怀尔河）面临的一个严重问题。

The paper analyzes the sensibility of parameters of thermodynamics model of glacial snow region by using the method of glue based on the data of headwater area of wulumuqi river in 1993 and 1994 .

以乌鲁木齐河河源区1993年、1994年数据为基础，采用glue法对冰川积雪流域热力学模型参数的敏感性进行了分析。
