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。
Based on the measured monthly runoff data from 26 hydrological stations at the outlet of the Tarim Basin, the variation regularities of annual runoff distribution in the Tarim Basin during the year were studied. Dividing the study area into four divisions, it is found by calculating the indicators of non-uniform distribution and concentration degree during the year of runoff that there is a certain correlation between the runoff and precipitation unevenness curve in section 1, while the runoff non-uniform coefficients The interannual variation was obviously lower than that of the normal precipitation, and the changes of runoff concentration periods 2, 3, and 4 were consistent with those during the temperature concentration period, indicating that the distribution process of runoff in Region 1 was mainly affected by precipitation. The distribution processes in Runoffs 2, Affected by temperature. The correlation analysis between monthly runoff, monthly precipitation and monthly temperature in each area further verified the above conclusions.
