Eco-environmental Problems of Wetland Resources Development and Countermeasures in Dongting Lake Area

洞庭湖区湿地面积约8.77×105hm2,复杂多样的湿地类型和生态环境蕴含了丰富的生物资源、气候资源、水资源、土地资源以及旅游资源。长期以来由于人类不合理的开发利用,导致洞庭湖区湿地面积和景观结构发生了很大变化,湿地生态功能亦受到严重影响和威胁。分析了洞庭湖区湿地的自然资源和开发利用面临的主要生态环境问题,并提出了洞庭湖区湿地资源开发利用和保护的对策。

The wetland in Dongting lake area is one of the largest freshwater lake wetland in China, covering an area of 8.77×105 hm2. The complexity and diversity of wetland types and ecoenvironment created rich biological resources, climate resources, water resources, land resources and tourist resources. However, owing to the unreasonable utilization of mankind for a long time, the wetlands have changed a great deal in area and landscape structure, the ecological function had seriously been influenced and menaced. The main problems of wetland resources development and utilization are analyzed, and the countermeasures of sustainable utilization of wetland resources in Dongting lake are put forward.
