本文通过对中国部湖泊近期演化及其对环境影响的比较研究，认为导致东西部湖泊近期大面积退缩的主要原因都是人类活动。平原区湖泊的许多传统功能正逐渐被水利工程所取代，今后湖区资源的开发应充分注意这一趋势。

COMPARATIVE STUDY ON THE RECENT CHANGE OF LAKES IN EAST AND WEST PLAIN AREA OF CHINA

Based on the comparative study on recent change of lakes in eastern and western plain area of China, this paper reveals the main causes resulting in lakes shrinking greatly in the two area from 1950's to 1980's. In the eastern plain area,the main cause is the reclaimation on lake area land,while in western plain lake area is irrigation. Both eastern lake ecology and that of west are very fragile compared with the great power of human activities. Most of traditional economic functions of plain area lakes are gradually substituted by that of water projects (mainly by reservoirs) and by the development of regional economy. This tendency mentioned above should be noticed in further development of lake resources.
