长江源区气温降水及径流变化特征

On features of temperature,rainfalls and runoff changes in source region of Yangtze River

以长江源区为例,介绍了其区内概况,分析了气温、降水量及径流量年内、年际变化趋势,并从气温、降水及径流量年内、年际变化特征两方面,对气候因子与径流量的变化特征进行了分析,为今后同类研究提供参考。

Taking the source region of Yangtze River as the example,the paper introduces its survey,analyzes the temperature,rainfalls,and annual changing trends for the runoff,and analyzes the changing features of the climatic factors and runoff volumes from the two aspects including the temperature,rainfalls and the annual changing features of the runoff volume,so as to provide some reference for similar research.
