近自然间伐对中龄林林分结构的影响研究
Research on Influence of Close-to-Nature Thining on Mid-Aged Stand Structure
摘要
Abstract
In the paper,some influence factors,such as forest stand structure,basal area at breast height,tree height,volume,space configuration,plant spacing area,etc.were analyzed before and after thinning in the close-to-nature management forest,and then revealed the impact trend of close-to-natural thinning on stand structure. Results showed that after the close to nature thining,the average of basal area at breast height,tree height,volume increased,the stand became more robust,and the mechanical stability of stand was improved.Although close to nature thinning was advantageous to the trees′optimizing development,advantages could not be realized in a short time.Close-to-nature thining made the minimum spacing and space configuration area increased,the grow space of trees expanded,the competition between trees eased,and the forest spatial distribution uniformed,and then improved the rapid growth potential of the whole forest.关键词
