生态系统服务研究是当前生态学与生态经济学研究的热点问题之一，目前直接针对耕地生态系统服务价值的研究正在越来越受到重视.该文对四川省2011年耕地生态系统的服务运用市场价值法、替代价格法进行了经济价值的估算.结果表明：四川省耕地生态系统服务正价值2261.72亿元，包括农产品服务价值、耕地固碳造氧价值、农作物净化大气环境服务价值和耕地保持养分循环服务价值；负价值66.63亿元，主要是化肥污染的经济损失.正负价值合计2328.35亿元.四川省耕地生态系统服务正负价值存在较大区域分异，成都市耕地生态系统服务提供正价值远高于其他市州，三州地区耕地生态服务价值最低.

The study of ecosystem service is one of the hot issues of ecology and ecological economics. The estima-tion of the farmland ecosystem service value is getting more and more attention. With the method of marketing value and the alternative price,this paper estimates the economic value of the service functions for the farmland ecosystem in Sichuan Province in 2011. The results indicate that the positive value of the farmland ecosystem services is ￥ 2,261.72 billion,which includes the service value of the agricultural products,fixed CO2 value of the farmland,the service value of purifying the atmospheric environment and maintaining the nutrient cycling of the farmland. And the negative value is ￥ 6.663 billion,which is the cost of chemical fertilizer pollution. The value reaches up to ￥ 2,328.35 billion. There are some differences of the service value of the farmland ecosystem among different prefecture cities in Sichuan,such as,the positive value that Chengdu offers ranks to the top,much higher than other cities,and those of the remote three prefectures(Ganzi,Aba and Liangshan)are the lowest.
