摘要
本文分析了江苏境内主要湖泊的降水量特征,揭示了长江是江苏各湖泊不同降水量特征的一条十分明显的天然界线;估算了太湖的降水效应,并据此推估出江苏主要湖泊的降水效应不太明显;江苏各湖泊的降水量与其水位年过程趋势相似,只是后者位相滞后于前者而已。
The precipitation characteristics of main lakes in Jiangsu Province are analysed. It is shown that the Yangtze River is a very evident boundary line for different precipitation characteristics of various lakes in Jiangsu Province. For example, the annual lake precipitation is over 1000mm (1030-1200) in south Jiangsu but less than 1000mm(850-950) in north Jiangsu, and the difference of monthly lake precipitation in Jun. and in Jul. is unevident in South Jiangsu, whereas the monthly lake precipitation in Jul. is almost twice as that in Jun. in North Jiangsu. A quantitative estimation is made on the precipitation effect of Taihu lake and it is suggested that the precipitation effect of the lakes in Jiangsu Prov. is not significant, with only a little reduction of precipitation over the lakes. The annual precipitation over the lakes varies similarily as their water level does, but with a phase-lead about a month.
