Abstract: From the land use vector data of Guangzhou-Foshan Metropolitan Area (GFMA) in 1990, 1995, 2000, 2005 and 2010, four types of agriculture and forestry ecosystem (cropland, forestland, garden and water body) were extracted. Then, we evaluated the GFMA’s agriculture and forestry ecosystem services value (AESV) based on Costanza’s method after adjusting the ‘ecosystem services value per unit area of China’s terrestrial ecosystem’ raised by Xie Gaodi through regional, functional and economic factor adjustment. The results showed that the total AESV had a wavelike upward trend due to the continuous development of economy and the increase of people’s living standards in GFMA. The AESV in GFMA was 413.74×108, 612.83×108, 582.88×108, 773.44×108 and 698.67×108 yuan in 1990, 1995, 2000, 2005 and 2010, respectively. During the studied period, water body’s service value grew fastest, which was 166.74×108 yuan, and followed by forestland and garden amounting to 103.01×108 and 47.74×108 yuan, respectively, while the cropland’s service value decreased by 32.56×108 yuan and the decreasing rate was 23.1%. Accor-ding to the spatial distribution, the AESV tended to decline from the northeast and the southwest to the central part in GFMA from 1990 to 2010. The proportion of individual service value to the total services value changed little, and the contribution of individual service value decreased in the order of water supply, waste treatment, biodiversity protection, climate regulation, soil formation and protection, gas regulation, recreation and culture, raw material and food production.
