近自然视域下混乔矮林经营技术研究

Research on Management Technique of Coppice-with-standards from the Perspective of Close-to-nature

在我国高度重视生态文明建设的新形势下,混乔矮林的培育前景是转化为乔林。本文以湖北省保康县混乔矮林为研究对象,将混乔矮林分为针阔混交型、目标树充足的阔叶混交型和目标树不足的阔叶混交型等3种类型,探讨了通过目标树经营法、转变经营法将混乔矮林转化为复层异龄混交乔林的技术措施。建议在混乔矮林经营过程中,要注重珍贵阔叶树种和野生动物生存环境的保护,以维护森林生物多样性。

In the new context of strengthening ecological civilization construction in our country,the prospect of coppice-with-standards is to be converted to arbor forests.The paper took the coppice-with-standards in Baokang County of Hubei Province as the study object,divided the coppice-with-standards into three types(broadleaf and conifer mixed forest,broadleaf mixed forest with enough future-crop-tree and broadleaf mixed forest with deficient future-crop-tree),and discussed the technical measures that converted coppice-with-standards into multi-layered mixed arbor forests with different ages by future-crop-tree management method and forest conversion management method.It was suggested that much attention should be paid to the protection of the precious broadleaf species and the habitats of wild animals,so as to maintain the biodiversity of the forest.
