摘　　要：在对谢高地等的生态系统服务价值系数进行修正的基础上,分析了1996-2008年广东省农用地变化所引起的农业生态系统服务价值变化,并应用相关性分析方法探讨了农业生态系统服务价值变化与影响农用地变化的总人口、GDP、城市化水平、第一产业比重、社会固定资产投资总额5个社会经济驱动因子之间的关系。结果表明:①1996-2008年间,尽管园地、水域的生态系统服务价值明显增加,但广东省农业生态系统服务价值以林地为主,其次为农田,林地和农田面积减小使其生态系统服务价值逐年减少,且林地和农田减小量大于园地和水域的增加量,从而使全省农业生态系统服务总价值在13年间降低了23.11×108元;②农业生态系统服务价值变化与总人口、GDP、城市化水平和社会固定资产投资总额之间存在极为显著的负相关关系,相关系数分别为-0.965、-0.887、-0.896、-0.883。农业生态系统服务价值变化与第一产业比重之间呈显著的正相关关系,相关系数为0.972。Based on the Xie Gao-di＇s coefficient of ecosystem services value, the change of land for agricultural use in Guangdong Province from 1996 to 2008 and the agroecosystem service values change caused by land use were quantitatively analyzed. And the relationship between agroecosystem service values and its major factors of social economy including the total population, GDP, the urbanization level, the proportion of primary industry and the investment of social fixed assets were explored by correlation analysis and sensitivity analysis. The results showed that： （1） although the value of garden plot and waterbody increased 27.79% and 12.44%, the agroecosystem service values in Guangdong during 1996-2008 mainly was woodland and farmland and decreased 2.09% and 13.90%. Because of the agroecosystem service values decreased by ￥71.75× 10^8 which was much greater than the value increased by ￥48.64× 10^8 in total, the total agroecosystem service values of Guangdong decreased ￥23.11 × 10^8 during the 13 years and the decrease of woodland and farmland area was the major reason. （2） The changes of agroecosystem service values in Guangdong Province had significant negative correlation with the total population, GDP, the urbanization level and the investment of social fixed assets and the correlation coefficient was -0.965, -0.887, -0.896, -0.883 respectively, while the proportion of primary industry had positive correlation with agroecosystem service values and the correlation coefficient was 0.972.
