| 摘 要： | 以渭河左岸较大支流千河流域为研究对象,基于长期气象观测资料,就不同时间尺度(包括月、年、10年)降水特征及其变化规律进行了分析,结合降雨量变化的分析结果,对流域径流量变化的原因进行探讨,指出降水减少是千河流域径流量减少的最直接、最主要的原因.此外,人类活动影响也起到一定的作用.

| Abstract: | Based on the long-term weather observation data,the characteristics and changes of monthly,annual and decennary precipitation along Qianhe Basin in recent 50 years were analyzed.According to the analysis on the changes of precipitation,the reasons for the changes of water runoff along Qianhe Basin were explored.It was pointed out that the decrease of precipitation was the most direct and most main reason for the reduction of water runoff along Qianhe Basin,and human activity also had a certain influence on ... |
