摘　　要：从广佛都市圈1990、1995、2000、2005和2010年5期土地利用矢量数据中提取出耕地、林地、园地和水域4类农林业用地.基于Costanza等生态系统服务价值计算方法,在对谢高地等提出的＂中国陆地生态系统单位面积生态服务价值＂进行区域修正及功能性和经济性调整的基础上,估算了1990—2010年间广佛都市圈农林生态系统的生态服务价值.结果表明：1990—2010年间,随着经济的不断发展以及人们生活水平的不断提高,居民对农林生态系统服务的支付意愿和支付能力逐年增强,使得广佛都市圈农林生态系统服务价值总体上呈波动上升趋势,1990、1995、2000、2005和2010年的服务价值分别为413.74×108、612.83×10^8、582.88×10^8、773.44×10^8和698.67×10^8元,20年间提高了284.93×10^8元,平均年增幅为2.7%.研究期间,总服务价值增加最多的为水域,达166.74×10^8元,其次为林地和园地,分别增加了103.01×10^8和47.74×10^8元.耕地的服务价值则降低了32.56×10^8元,降幅达23.1%.在空间分布上,广佛都市圈各年的农林生态系统服务价值均表现为从东北和西南部向中部减少的趋势.各类型农林生态系统服务价值所占比例在年际间变化不大,总体表现为：涵养水源〉废物处理〉生物多样性保护〉气候调节〉土壤形成与保护〉气体调节〉娱乐休闲与文化〉原材料提供〉食物生产.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 peo- ple＇ s living standards in GFMA. The AESV in GFMA was 413.74×10^8, 612.83×10^8, 582.88×10^8, 773.44×10^8 and 698.67×10^8 yuan in 1990, 1995, 2000, 2005 and 2010, respectively. During the studied period, water body＇ s service value grew fastest, which was 166.74% l0s yuan, and followed by forestland and garden amounting to 103.01×10^8 and 47.74× 10^8 yuan, respectively, while the cropland＇s service value decreased by 32.56×10^8 yuan and the decreasing rate was 23.1%. According 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 pro- tection, gas regulation, recreation and culture, raw material and food production.
