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 functions. 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 2.4×105. 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.
