| Abstract: | [中文摘要]：以塔里木盆地出山口26个水文站实测月径流资料为基础,研究了塔里木盆地出山口径流年内分配变化规律。将研究区划为4分区,通过计算径流年内分配不均匀性和集中程度指标发现,1区径流和降水不均匀系数曲线之间呈现出一定的相关性,而2、3、4区径流不均匀系数年际变化明显较降水平稳,且2、3、4区径流集中期与气温集中期的变化较为一致,说明1区径流年内分配过程主要受降水影响,2、3、4区径流年内分配过程主要受气温影响。对各区月径流与月降水、月气温之间做相关性分析,进一步验证了以上结论。
[英文摘要]：Based on the monthly runoff data of 26 Mountain pass stations in Tarim Basin,the annual distribution characteristics of runoff were studied.Two indices of uneven coefficient and concentration degree were calculated in the four areas of Tarim river basin.It was found that the runoff and uneven coefficient correlation is significant in the first area and the uneven coefficient of run off in 2,3 and 4 areas is more even than the precipitation.The results showed the runoff is mainly related to temperature in the first area and in other three areas the runoff is mainly controlled by the temperature . Advanced analysis for the correlati on on the runoff and p reci p itati on and temperature demonstrated the results further. |
