天然混交林水土保持生态修复技术研究

Study on the Ecological Rehabilitation Technology of Natural Mixed Forest Conservation of Water and Soil

应用群落边缘效应原理和林窗更新等生态学理论,根据种间关联性分析结果,确定林分内建群种与各种群的种间关系,对与建群种有竞争关系的树种进行适宜间伐,形成林窗和边缘界面层。根据群落空间分布格局和林下更新的分析,阐明适宜人工干预对生态修复的促进作用,为水土保持建设提供一种新的有效途径。

Applying forest window renewal and community edge effect theory, according to inter-species connection analysis result, the relation between the forest community and species is determined and suitable cutting is made in species that has competition relation with community. The shape grows into forest window and forest edge. With the analysis of the community spatial distribution pattern and the forest renewal,it is expounded that suitable artificial intervention can promote ecological rehabilitation,which provides a new effective way for the conservation of water and soil,
