洞庭湖区洪涝灾害成因与防治对策研究

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

在论述洞庭湖区洪涝灾害概况的基础上 ,分析了泥沙淤积与围湖垦殖、外洪内涝交织、区域协调机构缺乏与管理体制不统一等洪涝灾害的成因 ,并提出了调整丘岗地利用结构与重建山区植被、构建避洪耐涝复合高效生态系统、建设分蓄洪区及协调人地、人湖关系等防治对策。

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.
