近50年西江径流量变化与气候变暖关系

Preliminary Analysis on Relationship between the Climate Warming and the Discharge of Xijiang River in the Recent 50 Years

利用西江流域年径流量资料、全球及西江流域历年气温和雨量资料,从气候变化角度出发,分析得出近50年西江实测径流量变化与气候变暖无直接关系,与流域的降水量变化关系明显。

The annual discharge data of Xijiang River in the recent 50 years（ 1956 - 2004） are analyzed together with the annual precipitation and temperature data of worldwide and the Xijiang River valley - wide. The results show that, from the view of climate change, the discharge of Xijiang River has no direct relation with climate warming in the recent 50 years, while it is closely related to the rainfall over the valley.
