Land consolidation project at a township level is one of key ways to build a beautiful countryside in China. However, an important scientific problem is how to evaluate the ecological benefits produced by the land consolidation at a township level. Two methods of ecosystem service valuation (ESV), namely equivalent correction and single ecosystem service, were used to evaluate the ecological benefits in a representative case study area-the Sanxing Town, Jintang County, Sichuan Province of China. In order to find a suitable evaluation method of the ecological benefits at a township level, a comparative analysis of differences of estimated results and reasons for the differences was conducted. It indicated that the value estimated by the single ecosystem service method (about 3.0×10⁶ Yuan) was 3.5% larger than that estimated by the equivalent correction method (about 2.9×10⁶ Yuan). Economic values of all kinds of ecosystem services, calculated by the equivalent correction method, decreased as follows:regulating service > support service > supply service > cultural service. While those calculated by the single ecosystem service method were in an increasing order:regulating service > support service > cultural service > supply service. Different bases and parameters for the two methods caused the significant differences in the evaluation results. Values of nutrient cycling maintenance service and aesthetic landscape service, estimated by the single ecosystem service method, were 46.90 and 6.94 times higher than those estimated by the equivalent correction method, respectively. Value of hydrologic regulation service, estimated by the equivalent correction method, was 5.93 times greater than that estimated by the single ecosystem service method. The single ecosystem service method more accurately and truly reflects values of ecological benefits than the equivalent correction method, since it uses different methods to flexibly evaluate any single ecosystem service according to its characteristics. Therefore, the single ecosystem service method is recommended for evaluation of ecological benefits produced by a land consolidation project in a hilly area of Southwest China at a township level.
