Stage Division in the Full-Cycle Operation Method and Optimization of Current Operational Measures
摘要
Abstract
To address the imperfection of the full-cycle operation method for natural secondary forests in the Xiaoxing'an Mountains,this study took these forests as the research object.By analyzing stand characteristics,the diameter class meth-od was introduced to divide stand development stages,and current operational measures were determined based on popula-tion quantity analysis,thereby optimizing the full-cycle operation method for natural secondary forests in the Xiaoxing'an Mountains.The results showed that:(1)Among the 20 stand structure indicators,16 were significantly correlated with the development stages divided by the diameter class method(p<0.05),comprehensively reflecting stand vitality,tree species composition,tree species diversity,structural characteristics,and disturbance degree.(2)There were significant differ-ences in stand structure among different development stages(p<0.05).With stand development,stand density and compe-tition index increased significantly(p<0.05),the gap between the actual basal area at breast height and the potential basal area at breast height widened,stand dominance decreased significantly(p<0.05),and stand quality urgently needed to be improved.(3)Population quantity characteristic analysis could quickly identify broad-leaved tree species with cultivation potential(growing populations among target tree species)in the current stands,thereby locking in target trees and interfer-ing trees.(4)With stand development,precious broad-leaved tree species exhibited poor regeneration.In the middle and late stages of full-cycle management,in addition to promoting the growth of Pinus koraiensis,attention should also be paid to the introduction and protection of precious broad-leaved tree species.关键词
