Abstract:: Taking low-slope hilly land in Jiangjin District of Chongqing City as the research object, we analyzed the exploitation potential of agricultural land, forestland and construction land, and by used the ecosystem services value (ESV) to evaluate the eco-environmental impacts of comprehensive land utilization. The results show that the theoretical potential area of low-slope hilly land in Jiangjin District is 137 652.55 hm², and the realizable potential area is 31 428.37 hm²; the land areas suitable for agriculture, construction and forest account for 74.19%, 11.27% and 14.53%, respectively, in low-slope hilly land. Exploitation of low-slope hilly land can optimize the structure of land use, and alter the original ecosystem service values. The land use type with the largest ESV is forestland, and ecosystem service system engineering has the largest contribution to biodiversity protection. ESV of the study area can occur positive change with the increase of 6.178 8 million yuan per year. The exploitation of low-slope hilly land can not only reasonably utilize land resources, but also improve the eco-environmental carrying capacity in the study area.
