摘 要: 以浅水草型湖泊白洋淀作为研究区,在现场调研的基础上,结合资源经济学和生态经济学的理论与方法,选择干淀危机之前、干淀时期和生态补水之后3个典型时期,采用市场价值法、旅行费用法、碳税法、替代费用法等方法对其生态服务功能进行价值评估,并分析不同典型水文条件对白洋淀湿地生态功能价值的影响。结果表明:3个时期白洋淀生态系统的生态服务功能价值分别为85 897.5,70 563.1,96 202.0万元,其生态功能价值随水位特征的变化比较明显,在各生态功能价值中,尤其以物质生产价值和水资源价值差距最大。进一步体现了生态水利调度的实施对于白洋淀生态系统的恢复及其生态功能价值的提升具有重要作用。
关 键 词: 区域生态学;生态功能;价值评估;水文特征;白洋淀湿地

Abstract: In this paper, the values of ecological service function of Baiyangdian wetland in three different years were evaluated by using the market value method, travel cost method, carbon tax method and substituted expense method. The influence of changes in water level in the different years on the values of ecological service function was discussed. The results showed that the values of ecological service function of Baiyangdian wetland are 85 897.5×104 Yuan, 70 563.1×104 Yuan and 96 202×104 Yuan in the three different years, respectively, and the effect of water level on the values is obvious. The values of substance produces and water resources fluctuate greatly.
