Abstract:The relative assessment model of “function equivalent” was proposed. Based on RS and GIS, the ecosystem services of Tianjin Binhai New Area in 2009 were assessed and the results of the ecosystem services fuction equivalent were classified and expressed in grid. The order of ecosystem services function equivalent in Binhai New Area (from the highest to the lowest ) were: wetland, water, forest, grassland, farmland, bare ground; the sum of the ecosystem services function equivalent of Binhai New Area in 2009 was 1068680.13, the ratio of function equivalent cells above Class Three was 71.22% .Generally, the ecosystem services function in Binhai New Area was relatively high. Finally, a comparison was made between the monetary value method and relative assessment method, there was a high correlation between the two methods. So feasibility and rationality of this relative assessment model was proved.
