Causes of flooding and waterlogging disasters in the Dongting Lake region and some countermeasures

Abstract

Abstract: Based on the general situation of flooding and waterlogging disasters in the Dongting Lake region, this paper analysized their causes, such as sediment deposition and excessive land reclamation at the lake marshes. Flooding out of the protective embankments and waterlogging in the farming fields existed at the same time. Coordinating agencies and integration of management were needed.Some countermeasures were put forward, such as regulating slope land usage structure, restoring vegetation in mountainous areas, constructing flooding and waterlogging resistant compound ecosystem, building flood-diversion and storage area, harmonizing the relationships between mankind and Land and between mankind and lake.

Key words: Dark coniferous forest, Bryophyte, Biomass, Hylocomium splendens, Rhytidiadelphus triquetrus, Changbai Mountain
