Abstract:: This paper took Shanghuang experimental area as an example, and took the ecological green equivalent as the measure index of the environmental impact assessment, to establish the ecology green equivalent mathematical model and surveyed the value of region green equivalent, then assessed the ecology environment situation based on the data of land use in 1982, 2000 and 2010. The result showed that the green equivalent was 0.88 in 1982, which meant that the ecosystem service function was not up to the standard; while in 2000, after about 20 years comprehensive ecological management in this area, the green equivalent reached up to 1.266, which indicated that the ecological environment had been improved in Shanghuang experimental area; after returning the farmland to forestland and grassland from 2000 to 2010, the green equivalent was 1.479 in 2010, which showed that the ecological service functions became more powerful. It is clear meaning and simple calculation to use the ecological green equivalent as the indicators of the regional evaluation of ecological environment.
