摘　　要：采用"功能当量"相对评估模型对滨海新区生态系统服务功能的供给量进行评估,并从供给与需求的角度出发,建立人类需求服务功能指标体系,以各生态系统类型所提供的"功能当量"为桥梁,重点研究人类需求服务功能的量化和方法,进而对天津市滨海新区生态系统服务功能进行供需量化分析,得出以下主要结论:滨海新区人均需求功能当量为0.43,人口总需求当量达10.7×105,以及生态缺口现状为2.4×105;针对目前新区生态系统功能呈现出供给小于需求的现状,从合理控制人口数量、增加生态系统面积、提高生态系统服务质量三方面提出指导性建议。The ＂functional equivalent＂ relative evaluation model is used to assess the supply of ecosystem services of Binhai New Area in this paper. From the perspective of the supply and demand of ecosystem services function, we established the index system of human needs service fimctions. Focusing on human needs service functions quantification and method, we have quantitatively analyzed the supply and demand of the Binhai New Area＇s ecosystem service function. The results are as follows. The per capita demand function equivalent was 0.43 in Binhai New Area and the ecological gap was 2.4×10^5. The Binhai New Area ecosystem services supply was less than demand. Some suggestions are given from three aspects, including reasonably controlling population, increasing ecosystem area, and improving the service quality of ecosystem services.
