洞庭湖区湿地资源可持续利用途径研究

湿地具有特殊的生态功能和社会经济价值。洞庭湖区湿地垦殖强度大,造成了生态环境严重退化的恶果。研究表明:控制人口总量,退田还湖,建立湿地自然保护区,大力发展避洪耐涝型湿地特色产业是保护和合理利用湿地资源的有效途径,且已取得了良好的社会、经济、生态效益。由此认为,如何协调好人口、资源与环境的关系是实现湿地资源可持续利用的战略目标。

A study on approaches to sustainable utilization of wetland in the Dongting Lake

Wetland is featured by its unique ecological function and socio-economical value.Due to reckless exploitation,the function of wetland is severely damaged and accompanied by the degeneration of ecological environment.Research shows that such approaches to sustainable uti-lization of wetland in the Dongting Lake are effective in the aspects of population control,polder removement,wetland restoration,establishment of wetland preservation area,development of in-dustries characteristic of wetlands in disaster avoiding and waterlogging tolerance.Sound eco-nomic,social and ecological benefits have been gained.Therefore it is held how to coordinate the rela tions among population,resources and environment are the strategic targets for the real-ization of wetland sustainable utiliza tion.
