摘　　要：【目的】通过构建林分经营迫切性评价体系,判断云勇林场两种阔叶混交林森林经营等级,提出相应的森林经营策略。【方法】以云勇林场两种阔叶混交林样地为研究对象,综合考虑其空间结构与非空间结构共10项指标,并对两种林分进行林分经营迫切性评价。【结果】样地1存在角尺度、目的树种优势度、健康林木比例、林木拥挤程度、天然更新等五项指标不符合评价取值,处在特别需要经营等级;样地2存在角尺度、天然更新、目的树种优势度共3个指标不符合取值标准,处在需要经营等级。【结论】针对两个样地存在的问题进行结构化经营设计,对于样地1中的林木,应该通过调整整体林木的分布格局进行改善,逐渐形成以樟树-假苹婆-木荷-山杜英为目的树种的优势树种组;对于样地2中的林木,可以通过调整个别伴生树种分布格局的方式来改善整体分布格局,形成以醉香含笑-观光木-深山含笑为目的树种的优势树种组,对两个样地中的萌生杉木和病腐木进行除萌和伐除处理,此外,应采取人工促进更新方式提升林分整体的更新等级。【Objective】By constructing an evaluation system for the urgency of forest management,the forest management level of two broad-leaved mixed forests in Yunyong Forest Farm was judged,and the corresponding forest management strategies were put forward.【Method】Taking the sample plots of two kinds of broad-leaved mixed forests in Yunyong Forest Farm as the research object,a total of 10 indicators of spatial and non-spatial structure were comprehensively considered in order to evaluate the urgency of forest management in the two kinds of forest stands.【Result】There are five indexes in plot 1,including neighbourhood pattern,dominance of target species,proportion of healthy trees,degree of forest crowding and natural regeneration,which do not conform to the evaluation value and are in the level of special need management.There are three indexes in plot 2,including neighbourhood pattern,natural regeneration,and dominance of target species,which do not meet the value criteria,and is in the class of need to be managed.【Conclusion】Structured management design was carried out for the problems existing in the two sample plots.For the trees in sample plot 1,the overall distribution pattern should be improved by adjusting the overall distribution pattern of the trees,gradually forming a dominant tree species group with Camphora officinarum-Sterculia lanceolata-Schima superba-Elaeocarpus sylvestris as the target species.For the trees in sample plot 2,the distribution pattern can be improved by adjusting the distribution pattern of the individual companion species,forming a dominant tree species group with Michelia macclurei-Michelia odora-Michelia maudiae as the target species.Sprouting Cunninghamia lanceolata and diseased rotten trees in the two sample plots should be removed or felled.In addition,artificial promoted regeneration should be used to improve the overall regeneration rating of forest stands.
