In order to provide scientific theoretical basis for the implementation of the project of returning farmland to forest under the new situation, Puding County of Anshun City, Guizhou Province was taken as the research area, four services such as soil conservation, water yield, carbon storage and habitat quality in 1990, 2000, 2010 and 2017 in Puding County were measured by using the value trade-off model of ecosystem services and transactions(InVEST). The results showed that:(1)the ecosystem service change indexes(ESCI)of water yield, carbon storage, soil conservation and habitat quality service in the three periods were different, some indexes remained stable, and the others doubled. The gain and loss ranges were not the same in terms of spatial distribution, and the same kinds of ecosystem services had not the same distributions in different time periods;(2)The distribution patterns of the four dominant ecosystem services also presented the significant spatial heterogeneity; the leading service of water yield mainly distributed in mountainous forestland, construction land and bare land; carbon storage services mainly distributed in forest areas; habitat quality leading services distributed in water body, forestland, grassland and cultivated land;(3)there were obvious synergistic relationships between soil conservation and carbon storage service, soil conservation and habitat quality service, carbon storage and habitat quality in Puding County; there was a good synergistic relationship between soil conservation and water yield;(4)multiple ecosystem service supply of type 4 and type 3 of hot spots in Puding County mainly distributed in the forest and grassland areas, and with the comprehensive development of the policy of returning farmland to forest(grass), type 4 and type 4 of hot spots area increased year by year; Type 0 and type 1 hot spots mainly distributed in the construction land and cultivated land areas of Puding County.
