以恰塔斯河为研究对象,采用单位线法分析研究产汇流特性。单位线本身是由实测资料反推出来的,其形成规律完全符合该流域汇流的特性,这也是单位线法主要的优点和使用效果较好的原因。若各次洪水推得的单位线变化不大,取平均后可用于预报。随着后期资料的不断完善,样本容量的增加,对单位线不断的验证,将会得出更加准确、符合流域特性的单位线。
A Brief Analysis on the Model Establishment of Production and Confluence in Chattas Basin on the North Slope of Tianshan Mountains
In this paper,Chattas River as the research object,using the unit line method to analyze the characteristics of confluence.The unit line itself is backderived from the measured data,and its formation law fully accords with the characteristics of the confluence of the target watershed,which is the main advantage of the unit line method and the reason why the application effect is better.If the unit line pushed by each flood changes little,take the average for forecasting,it is also possible.In addition,with the continuous improvement of the data and the increase of the sample size in the later period,the unit line was continuously verified and continued to be calculated to obtain a more accurate unit line in line with the characteristics of the basin.
