利用夏季0℃层高度推求无资料地区河流年径流序列——以若羌河为例
Calculation of runoff series in ungauged basins from the 0 level heightin summer: a case of Ruoqiang River Basin
摘要
Abstract
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 in 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 (Cv) 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.关键词
