摘要
在帽儿山林场老爷岭生态站内设置次生林的典型样地,并对样地内的几种天然次生林的数据进行调查。研究用方差均值比率法研究老爷岭次生林群落主要树种的分布格局及其动态,并且做出相关的数据分析。主要选择当地典型的次生林类型进行调查,类型包括白桦林、蒙古栎林、硬阔叶林等。分析表明影响种群分布格局的因子大致归纳分为两类:第一:物种本身的生物学特性,第二:由于环境条件引起的生物学特征。并且对各林分主要树种分布格局及其动态的分析,揭示林分的未来发展趋势。
Representative plot were located at laoyeling ecological station in maoershan. Investigation was carried out in several sorts of natural secondary forest, studying the distribution pattern and dynamic of primary species of natural secondary forest with variance mean ratio matter in lanyeling ecological station, and simutaneity analyzing the related data. investgating the typical forest types such as forests of birch , mongolian oak and hard broad leaf ect. The analyzed results show that the factors which influenced the population structure generally can be concluded into two types： a. biological characters of species, b. biological charat,ers caused by environment. The distribution patterns and the dynamic of primary species are Also analyzed and this can open out the futurc trends of forst crop.
