天子湖国家湿地公园生态系统服务功能价值评估

Evaluation of ecosystem service value of Tianzi Lake National Wetland Park

本文根据天子湖国家湿地公园的湿地资源特点,选取了9项生态服务功能的价值进行了评估,并与都昌北鄱阳湖湿地和黄河三角洲自然保护区湿地的单位面积湿地生态服务价值进行了对比。结果表明:天子湖国家湿地公园生态系统服务功能总价值为23271.08万元,其中固碳释氧价值为14177.11万元,占总服务价值的60.92%;其次是水资源供给和防洪蓄水价值分别为3794.88万元、2452.20万元,分别占总服务价值的16.31%、10.54%。天子湖湿地单位面积生态功能服务价值29.68万元·hm-2,明显高于都昌北鄱阳湖湿地单位面积生态功能服务价值18.33万元·hm-2,且天子湖国家湿地公园单位面积的湿地服务价值明显高于黄河三角洲自然保护区湿地。

Based on the characteristics of Tianzi Lake National Wetland Park wetland resources,the values of 9 ecological service functions were selected to evaluate and compared with the unit area wetland ecological service value of the north Poyang Lake wetland in Duchang and the wetland in Yellow River Delta Nature Reserve.The results showed that the total value of ecosystem service in Tianzi Lake National Wetland Park was 232710.8 thousand yuan,among which the value of carbon sequestration and oxygen release was 141771.1 thousand yuan,accounting for 60.92%of the total service value,followed by water resources supply and flood control storage value respectively of 37948.8 thousand yuan and 24522 thousand yuan,accounting for 16.31%and 10.54%of the total service value.The service value of ecological function per unit area of Tianzi Lake wetland was 296.8 thousand yuan·hm-2,which was significantly higher than the unit area ecological function service value of north Poyang Lake wetland in Duchang,with 183.3 thousand yuan·hm-2,and the service value of Tianzi Lake National Wetland Park value per unit area was significantly higher than that of the wetland of Yellow River Detta Nature Reserve.
