摘要: 鄱阳湖湿地是永久性淡水湖泊,湿地水位随季节性洪枯水位而变化,而周期性地显露或淹没,这种变化直接影响鄱阳湖湿地的效益,包括湿地用途、湿地生态功能、湿地属性。评估这些效益的方法有直接市场评价法,揭示偏好与替代品市场法,陈述偏好法。本文着重分析鄱阳湖湿地的主导服务功能,并对涵养水源功能、洪水调蓄功能、保护土壤功能、固定CO2功能、释放O2功能、污染物降解功能、生物栖息地功能进行了价值的货币化评价研究,得到鄱阳湖湿地主导服务功能的总价值为3.627×1010元。其中调蓄洪水功能最大,占总服务功能价值的43.98%;其次是降解污染功能,占总服务功能价值的38.49%。

Abstract: Poyang Lake is a permanent fresh water lake,with water level changing with the seasonal variation of flooding and drying.The benefits of Poyang Lake include direct products,ecological functions and wetland characteristics.Three types of methods were used to evaluate the wetland ecosystem service value:direct market evaluation,replacement market,and stating partiality method.This paper stressed on the main serve functions of Poyang Lake,and provided monetary evaluations on the functions of water storage,flood regulation,soil protection,CO2 fixation, O2 release,soil and water purification,and habitats.The results revealed that the total monetary value of the main functions of Poyang Lake was 3.627?1010 yuan.The most important function was flood regulation,which was about 43.98% of the whole value.The second was soil and water purification,about 38.49% of all.
