选取西南丘陵山区重庆市荣昌县为研究区，以1996--2010年土地利用变化数据为基础，探讨土地利用变化对生态系统服务功能价值变化的影响，以客观刻画生态系统服务功能的状态和过程。研究结果表明：①受重庆直辖、西部大开发、国家退耕还林政策等主要驱动因素影响，区域人类活动加剧了对土地利用方式和程度的改变，致使研究期间耕地面积减少了3387．16hm^2、建设用地和林园地分别增加了3634．40hm^2和11447．64hm^2；②受生态退耕还林等主导因素的作用，研究期间区域生态系统服务价值净增了19264．09万元，土地利用变化对生态环境影响总体呈现正效应，除因耕地面积减少导致食物生产生态服务功能价值下降214万元外，其余生态服务功能均有不同程度的提高。

Changes in regional land use ecosystem service value objectively reflect the state and the process of ecosystem service. Based on dynamic data of land use from 1996 to 2010 in the hilly areas of southwest China, this paper discusses the effect of land use change on the ecosystem services value, with Rongchang County, Chongqing City as the research area. The results show that the areas of the farmland decreased 3 387. 16 hm2, construction land and forest increased 3 634. 40 hmz and 11 447.64 hmz during the 15 years, mainly because the human activities in those areas have intensified the change in the manner and extent of land use due to the driving factors of Chongqing turning to a municipality, great development of western regions and the national policy of returning the grain plots to forestry, and that influenced by the ecological reforestation, the net growth of ecosystem service value of the area was 192. 640 9 million, land use change impact on the ecological environment showing an overall positive effect, and the rest of ecosystem service value rose in varying degrees except for the decline in the value of 2.14 million yuan caused by the reduction of arable land.
