干旱区与湿润区湖泊降水效应之比较

本文在引证并对比分析前人研究成果的基础上认为：无论湖泊位于何处，至少从理论上来说，湖泊的降水效应是普遍存在的。关于博期腾湖的实际观测资料表明，，干旱区湖泊的降水效应可能不同于湿润区湖泊，湿润区湖泊通常湖面降水少于陆面。干旱区湖泊则可能出现相反的情况，从理论上来说，不论干旱区湖泊还是湿润区湖泊都存在着出现与上述结论相反的现象的可能性。

COMPARATIVE STUDY ON PRECIPITATION EFFECT OF THE LAKES IN HUMID AND ARID AREAS

Based on summarizing the studies of predecessors on precipitahon effect of 1akes, some conclusions show that the precipitation effect of lakes exists commonly wherever the lakes are, from a view of climatical theory at least. Most observed data show that the precipitation on lake water surface is less than that on land surface nearby lake area, while Bostan Lake is an exception, the precipitation on its water surface is more than that on land surface nearby the lake area. Thus, it can be inferred that the precipitation effect of some lakes in arid area may be different from that or the lakes in humid area. The causes arising the difference mentioned above is discussed in the paper.
