摘要
该研究以生态系统服务功能为切入点,基于流域生态系统特点梳理流域生态用地的内涵,将流域土地利用现状与流域生态系统服务功能相衔接,构建流域尺度的生态用地分类体系,把流域生态用地划分为水源涵养、生物保护、水土保持和景观休闲4个一级类型、9个二级型、25个三级类型,以期为流域生态用地的保护提供参考。
In this study,the conception and definition of ecological land in watershed was reviewed The conclusions were as follows:(1)the ecological land in watershed refers to the land use type that provides and exerts the main eco⁃system service function.(2)Based on the connection between land use status and ecosystem service function,a water⁃shed scale ecological land classification system was constructed.The ecological land in the basin is divided into 4 first-grade types,9 second-grade types and 25 third-grade types,among which the first-grade types include water conservation,biological protection,soil and water conservation and landscape leisure.It is expected to provide a ref⁃erence for the protection of ecological land in the watershed.
