中文摘要	新疆南部阿尔金山一昆仑山北坡发育的河流主要以冰雪融水为补给来源,该区域的许多河流都存在观测资料稀缺或无实测资料情况,为满足水资源管理以及开发利用对基础数据的需要,本文以资料稀缺的若羌河流域为例,通过对阿尔金山北坡40 a来夏季0℃层高度变化进行分析,并与参证河流车尔臣河地表年径流系列进行线性拟合,推算若羌河1964-2006年的年径流序列,最后与传统综合水文分析方法以及短时期实测资料做对比.得出以下结论:(1)以冰雪融水为主要补给源的干旱区河流,其年径流与夏季O℃层高度具有较好的相关性,利用0℃层高度推求年径流方法可行.(2)以冰雪融水补给为主的若羌河,变差系数Cv值在0.1-0.17之间,河流年际变化较小.(3)在过去40 a间,若羌河径流量存在阶段性变化,总体呈增加趋势,径流变化与气候变化关系密切.该研究为西北干旱区的无资料地区水资源开发利用研究提供服务
英文摘要	Located in the northern slopes of Altun Mountains and Kunlun Mountains, many rivers, which were supplied by snow and ice melt water, had few observational data. In order to meet the needs of water resource management, the research on hydrological reconstruction and prediction in ungauged basins has gradually become the focus of programs established by different methods. By the analysis of the variety of 0℃ level height in the northern Altun region, this paper took Ruoqiang River as an example, analyzed the trends of the 0℃ layer in the recent 40 a. After that linear fitting it with the runoff of the Qarqan River, the paper established the depth of runoff formula for the height of 0℃ level. Then, according to 40 years of 0℃ level height series, the runoff of Ruoqiang River’s time series from 1962 to 2004 were reconstructed. Finally, the paper compared this method with integrated analysis. The main conclusions are as follows:(1)the annual runoff and the summer of height 0℃ has a good relationship m some arid areas where snow and ice melt water as the main supply source of the river. The way of using 0℃ high level to analyse annual runoff calculation method is feasible.(2)runoff recharged mainly by snow meltwater, the variation coefficient (C_v)of annual runoff was between 0.10 to 0.17, its numerical value is relatively less, which show that annual runoff volume changes little.(3)For the recent 40 years, the correlation is significant between annual runoff of Ruoqiang River and climate change. This research can provide information services for the data scarce regions of the arid areas of water resources development and utilization
