摘要
鄱阳湖是我国第一大淡水湖泊,也是国际重要湿地,在维系长江水量平衡和生态安全方面,发挥着十分重要的作用和功能。近年来,鄱阳湖生态环境受到经济发展和人口增长的威胁,主要表现为:湿地生态系统退化,湖泊生态功能下降,流域生物多样性减少,水生植被萎缩,水污染程度日趋严重。湖区内产业结构和资源利用的不合理也限制了其经济发展。建设鄱阳湖生态经济区发展战略的确立要求江西尽快探索出一条保护生态与发展经济的双赢之路。结合鄱阳湖区生态环境与资源利用现状,通过2a多的集成研究与示范,已形成了湿地恢复、沙化综合治理、农业污染治理和资源合理利用等十多种技术模式,在保护环境的同时提高了农民收入,为实现鄱阳湖生态经济区建设目标提供了技术支撑。
Poyang Lake is not only the largest fresh water lake in China,but also an important international wetland,which plays a great role in maintaining water balance and ecological security of the Yangtze River.In recent years,rapid economic development and population growth present threats on ecosystem of the Poyang Lake Basin,such as wetlands degradation,lake ecological functions deterioration,biodiversity reduction in catchment,aquatic vegetable degradation and water pollution.The strategy of establishment of Poyang Lake Eco-Economic Zone requires a win-win situation in terms of environmental protection and economic development.Based on the existing situation of the Poyang Lake Region,the study and demonstration on wetland restoration,integrated management of sandy land,agricultural pollution treatment and reasonable natural resources utilization have been conducted for 3 years.More than 10 technical models have been developed,which will protect environment and increase income for the local people.They can support directly the construction of Poyang lake Eco-Economic Zone.
