区域水土保持生态修复模式及效果评价——以长江流域两当河上游为例

Ecological rehabilitation effect assessment of soil and water conservation model-A case study of the upper reaches of Liangdang River,Changjiang Basin

    摘要
  • 摘要: 根据长江流域两当河上游的环境特点,提出了自然力与人工辅助相结合的水土保持生态修复技术及建设模式,包括退化林地修复模式、荒山荒坡修复模式、农地修复模式和生态辅助措施.并应用遥感技术和地面人工调查相结合的方法,对生态修复模式实施的效果进行评价.结果表明,两当河退化生态系统修复效果明显,农田退化系统恢复效果显著,植被盖度提高,种群数量增加,生态系统向良性演变.

     

    Abstract: Ecological rehabilitation models of soil and water conservation combining artificial measures and natural power in the upper reaches of Liangdang River of Changjiang Basin were advanced in accordance with environmental characteristics of the study area. T
