近自然阔叶化树种配置模式设计

Design of Broad-leaved Trees Distribution Model for Close-to-Nature Forest

从分析近自然林业经营与阔叶化的内在联系着手,根据淳安县森林植被调查情况,综合原生植被、地类,土壤和立地质量四大因子的差异为设计依据,以地带性顶级群落及进展演替中期的森林植被类型为目标林分,选择或培育现有立地条件下自然适宜生长的乡土树种,设计了24个近自然阔叶化树种配置模式,其中:营造型5个,补植型4个,改造型4个,定向封育型5个,封禁型6个。

Analysis was made on interaction between close-to-nature forest management and broadleaf forest. Based on investigation on forest vegetation in Chun＇an, Zhejiang province and on four factors such as primary vegetation, soil and site quality, 24 close-to-nature forest models were designed selecting zonal climax forest type and in middle stage of succession as target forest, selecting and cultivating native tree species. Among these models, 5 ones were constructed, 4 filling-up, 4 transformed, 5 directive breeding and 6 nature growth.
