Water quality deterioration of Jianghan lake group indicates the damage of lake ecosystems which has affected the wetland functions.

The influence of human activities on the swamping of Jianghan lake groups is discussed as follows: The siltation of the lakes has been accelerated since plants in those lakes were destroyed as a result of human activities; Reclaimed land from lakes results in lake shrinking.

It is considered that rebuilding the link between the lakes and the rivers is very important,and 13 lakes of the Jianghan Lake Group were selected for the present study.

The paper analyses the major characteristics of the ecosystem in the Jianghan lakes aswell as the factors affecting its stability The performance characteristics and the measurement index are alsoincluded in the paper.

The essay analyses the effect of the Jianghan Lakes on the air temperature and precipi-tation based on a close study of the Honghu Lake and studies the effect of the land reclamation from lakemarshes on the precipitation in the lake areas.
