摘　　要：本文以2000年、2010年和2020年的土地利用数据为基础,运用土地利用动态度、生态系统服务价值当量和生态系统服务变化指数等指标与方法,测算研究区生态系统服务价值及其“生态服务转型”的状态与趋势。结果表明:2000-2020年,河北地区土地利用类型主要以农田和森林为主,其中农田和草地呈持续减少态势,森林、湿地和建设用地呈净增加态势;近20年来,农田、森林、草地、湿地的生态服务价值均呈递增趋势,其中草地和农田的生态服务价值变动较小,而森林和湿地的变动幅度相对较高;2000-2020年,除了农田表现为从“强增益”转向“无明显变化”状态外,草地和森林在后10年都进入“弱增益”状态,湿地则进入“强增益”状态,为实现土地利用规划目标,未来15年,森林和湿地还应实现“生态系统服务转型”的“强增益”和“弱增益”模式。本研究的开展将有助于完善土地利用调控政策和配套文件,加强政策落实,推动自然资源综合审计制度,使河北地区土地利用向着国土规划目标来顺利实现“生态系统服务转型”。Based on land use data in 2000,2010 and 2020,this study used land use dynamic attitude,ecosystem service value equivalent and ecosystem service change index to estimate the status and trend of ecosystem service value and its“ecosystem service transformation”in the study area.The results showed that farmland and forest were the main types of land use in Hebei province from 2000 to 2020.Farmland and grassland decreased continuously,while forest,wetland and construction land increased net.In recent 20 years,the ecological service values of farmland,forest,grassland and wetland showed an increasing trend,in which the ecological service values of grassland and farmland changed little,while the ecological service values of forest and wetland changed relatively high.From 2000 to 2020,farmland changed from“strong gain”to“no significant change”,grassland and forest entered the“weak gain”state in the last decade,and wetland entered the“strong gain”state.In order to achieve the land use planning target,in the next 15 years,forests and wetlands should also achieve“strong gain”and“weak gain”models of“ecosystem services transformation”.This study will help to improve the land use regulation policies and supporting documents,strengthen the implementation of policies,promote the comprehensive audit system of natural resources,and make Hebei land use to achieve the goal of land planning to achieve the“ecosystem service transformation”smoothly.
