To fu1ly reveal the water abnormity and its formative causes in Dongting Lake during recent decades, this paper takes Dongting Lake as a big system. Researches through a variety of methods such as the relation between water-level and runoff show: (1) The runoff on the same water-level reduces 1200 m3/s-2800 m3/s in the lower reaches of the four rivers flowing into the lake, the water-level with the same runoff runs up 0.49 m-1.28 m; (2) The dividing-water ratios of the three bayous of the Jingjiang River reduces by 19.2%, and the dividing-sand ratios 25.1%; (3) Great changes have taken place in the relation between water-level and runoff in the main flooding roads such as Li River, Songzi and southern Dongting Lake etc.; (4) The natural regulation and storage capacity fall off by 40%, the water-level with the same runoff at the bayous drives up 1.80 m-2.50 m; (5) The relation between lake and protective embankment is often at hazard during the period of July and August. The main reason is that the filling-up of mud-sand arises a vicious circle which leads to environmental function changes of the lake system, and the water-sand adjustment from the three curve-cuttings on the lower reaches of Jingjiang River accelerates the change process.
