湖北省湿地生态系统服务功能评价

The Evaluation of Wetlands Ecosystem Services Function in Hubei Province

运用市场价值法、生态价值法、固碳价值法、影子工程法等计算方法及国内外的研究成果,分资源功能、生态功能和人文功能对湖北省湿地的生态系统服务功能进行了评价。结果表明:湖北省湿地的生态系统服务功能总价值为4 279.84亿元/a,其中湿地的固碳产氧价值最大,为1 606.06亿元/a,占总价值的37.53%。湖北省湿地的直接价值为1 553.09亿元/a,间接价值为2 726.75亿元/a。湖北省湿地有着重要的、多样的生态系统服务功能,其中固碳产氧是最主要的服务功能,在调节大气组分,减缓温室效应等方面有重要的意义。

The calculation methods such as the market value method,the ecological value method,carbon sequestration value method,the shadow engineering method and results of research domestic and international have been used,the ecosystem services function of wetlands in Hubei Province was evaluated in terms of resource function,ecological function and human features.The results showed that： the total value of wetland ecosystem service function in Hubei Province is 427.984 billion yuan each year,in which,the value of carbon sequestration and oxygen capacity is maximum,is about 160.606 billion yuan each year,about 37.53% of the total value.The direct value of wetlands in Hubei Province is 155.309 billion yuan each year,the indirect value is 272,675 billion yuan each year.There are important and diverse ecosystem services function for wetlands in Hubei Province,in which,carbon sequestration and capacity of oxygen is the most important service function,it is of significance to regulate composition of atmospheric and slow down the greenhouse effect etc.
