【摘要】 我国南方红壤区严重侵蚀退化马尾松林地土壤极度贫瘠,加之退化面积广等因素,导致其恢复的难度加大,如何恢复侵蚀退化马尾松林地成为当前面临的一个艰巨而又迫切的任务,因此加快相关方面的研究和治理,探讨其退化机理,解决生态恢复关键技术,对于推动红壤区的生态建设具有重要意义。该文从土壤退化、人为因素、马尾松的生物学特性等方面阐述了马尾松林地的退化机理,总结了退化马尾松林地生态恢复的途径和模式及其产生的生态环境效应,并提出了马尾松侵蚀退化林地进一步研究的展望,以期为退化马尾松林地生态修复的后续研究作一参考。更多还原

【Abstract】 In the red soil area of southern China,because of erosion and degeneration of Pinus massonian woodland,extremely leanness of soil and large degeneration area,it is difficult to recover ecology of degenerated Pinus massonian woodland.How to recover the eroded and degenerated Pinus massonina woodland has been an arduous and insistent mission.So,it is significant for driving zoological construction of red soil to expedite correlative research and disposal,probe into mechanism of its degeneration and resolve critical technique problem of recovering resuming ecology.In this thesis,we expatiate on degenerating mechanism of Pinus massonian woodland in light of soil degeneration,man-made factors and biological characteristics of Pinus massonian,and then summarize approaches and modes for recovering ecology of degenerated Pinus massonian woodland.In the end,we provide a view of further research on how to recover eroded and degenerated Pinus massonian woodland,in order to provide reference for future research on how to recover ecology of degenerated Pinus massonian woodland.更多还原
