摘要： 基于土地整治引起的变化特征，建立生态服务价值估算模型，定量评价湖北省内江汉平原、鄂西山地和鄂中丘陵3种不同类型土地整治引起的生态效应.结果表明：土地整治后，平原型项目区总生态服务价值损失0.3%，食物生产等4项功能的生态服务价值增加，水源涵养等5项功能的生态服务价值减少；丘陵型项目区总生态服务价值损失14.6%，食物生产的生态服务价值提高55.2%，其余8项功能的生态服务价值均减少；山地型项目区总生态服务价值损失19.9%，食物生产的生态服务价值提高24.9%，其余8项功能的生态服务价值均减少.丘陵和山区土地整治存在明显的“以生态换生产”的价值转换过程.

Abstract: A model for estimating the ecosystem services value under effects of land consolidation was built to quantitatively evaluate the ecological effects of three different types of land consolidation projects in Jianghan Plain, middle hilly region, and western mountainous area of Hubei Province. With the implementation of the projects, the total value of ecosystem services in Jianghan Plain was decreased by 0.3%, among which, the values of food production service and other three services increased but those of water conservation and other four services decreased. In hilly region, the total value of ecosystem services was decreased by 14.6%, with the value of food production service increased by 55.2% and those of other eight services all decreased. In mountainous area, the total value of ecosystem services was decreased by 19.9%, with the value of food production service increased by 24.9% while the values of other eight services all decreased. In the land consolidation in the middle hilly region and western mountainous area of Hubei Province, there was an obvious conversion process ‘from ecology to production’ in the ecosystem services value.
