黄河三角洲湿地主导生态服务功能价值估算

Value Estimates of The Dominant Ecosystem Services in Yellow River Delta Wetland

黄河三角洲湿地是全球暖温带最典型的河口三角洲湿地,具有多种生态服务功能。本文依据每种生态功能的特点和作用机理,分别运用生态经济学、环境经济学或资源经济学的方法对各主导生态服务功能的价值进行了量化估算。结果表明:在黄河三角洲湿地10项主导生态服务功能中,蓄水调洪和降解污染物的功能价值最大;黄河三角洲湿地单位面积价值大约是全国湿地平均单位面积价值的10倍,其中自然湿地的单位面积价值远高于人工湿地的单位面积价值。本研究结果使人们直观地看到了湿地给人类带来的福利,为湿地生态资源的合理定价、有效补偿提供了科学依据。

The Yellow River Delta wetland is the world＇s most typical estuarine delta wetland in warm temperate zone, with a wide range of ecosystem services. In this article, based on the characteristics and mechanism of each ecological functions, it did the quantitative estimates of the value of each dominant ecosystem services, using approaches of ecological economics, environmental economics or resource economics, respectively. The results showed that： in the ten dominant ecosystem services of Yellow River Delta wetland, the values of the flood water storage and the degradation of pollutants have the largest function value, the value per unit area of Yellow River Delta wetland is about ten times of the country＇ average, and the natural wetland unit area value is much more than the artificial wetland. The results of this study make it intuitive to see the benefits of wetland to humans, and provide a scientific basis for the reasonable pricing and efficient compensation of wetland ecological resources.
