近自然视阈下混乔矮林经营技术探析

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,以维护森林的生物多样性。

Research on Management Technologies of Coppice with Standard Forests from the Perspective of Close-to-Nature Forestry

In the new context of strengthening ecological civilization, the prospect of coppice with standard forests is to be converted to high forests. The article takes the coppice with standard forests in Baokang as the study object, discusses the technical treatments to convert three kinds of coppice with standard forests (broadleaf and conifer mixed forest, broadleaf mixed forest with enough future crop trees and broadleaf mixed forest with deficient future crop trees) to multi-layered, mixed, and high forests with different age classes by applying future-crop-tree management and forest conversion management. It is suggested that much attention should be paid to protect precious broadleaf species, maintain the habitats of wild animals and preserve the forest biodiversity during the management of coppice with standards forests.
