摘要
通过对森林生态系统保全功能评价方法的研究,建立用常规数据进行满足森林经营要求的功能评价方法,可为指导森林经营管理提供理论基础。以辽宁省清原县大边沟林场草皮沟岭的第21林班为例,对森林生态系统保全功能进行了评价研究。采用稀少性、多样性、近自然性这3个评价基准进行评价,结果表明:林班中的所有小班森林生态系统保全功能评价均为"高",说明各小班该项功能发挥良好。但与理想目标比较,42小班没有稀少种并且近自然度等级中等;43与45小班近自然度等级为"中等",其余2个评价基准为"高;"48、52与55小班无稀少种。
In order to provide the theoretical basis for the forest management,the function evaluation method to meet the forest management requirements by the normal data should be established.In this paper,based on the 21th forest compartment of the Caopigou ridge of Dabiangou Forest Farm in Qingyuan Country,Liaoning Province,the three evaluation standards including sparsity,diversity and near naturalness were used to evaluate the forest ecosystem preservation function.The results showed that the forest ecosystem preservation function of all forest subcompartments in the compartment was ＂high＂,indicated their well-function.There was not sparsity in the 42th forest subcompartment and its near naturalness level belonged to medium.In the the 43th and 45th subcompartment the near naturalness level was also ＂medium＂,while the other two evaluation standards were ＂high＂.There was not the sparsity in the 48th,52th and 55th subcompartment respectively.
