中文摘要: 利用累积距平法对兰江流域近43年(1961—2003年)气温、降水量和径流量资料进行分析
，研究兰江流域气候变化及其气候变化对水资源的影响。结果显示：兰江流域近43年来气
温、降水量总的趋势是上升的；1990年代是兰江流域气温上升和降水增加最显著的时段
，
主要表现在冬春气温明显上升，夏季降水量明显增加；兰江流域年径流深与年降水量基本保
持同步变化。兰江流域过去43年的气候变化对流域内水资源产生了较大的影响，而且由于兰
江流域内水资源空间分布差异较大，致使流域内人均水资源占有量较少的金华地区易受气候
变化影响而出现供水紧张。
Abstract:The climate change and its impacts on water resources in recent 43 years (1961-2
003) in the Lanjiang River Basin are studied by analyzing the temperature, preci
pita
tion and runoff with the cumulative departure method. The results show that the
temperature and precipitation of the Lanjiang basin had a rising trend in the re
cent
43 years. Since 1961, the temperature and precipitation have increased most in
the 1990s which is contributed by rising in temperature of winter and spring and
in precipitation of summer. The annual runoff of the Lanjiang River Basin keeps
the
same trend as the annual precipitation. Thus the climate change in the Lanjiang
Riv
er Basin has the impact on it's water resources. There is a difference in spatia
l distribution of the water resources in the Lanjiang River Basin, and the Jinhu
a City in the Lanjiang River Basin is subject to climate change which can resul
t in a shortage of fresh water.
