摘　　要：利用对小兴安岭林区典型低质林进行实地调查获得的样地森林资源的详细资料,应用多元统计分析理论对林分树种、林分密度、林分径级、林分多样性和丰富度以及土壤状况等进行了分析,筛选造成低质林分的主要影响因子。在分析主要因子变化过程的基础上,确定了低质林划分的技术参数,据此划分了低质林的不同类型:非经济型低质林、低密度型低质林、草原型低质林、生长潜力型低质林和高肥低效低质林。Species composition, stand density, diameter-class distribution, stand diversity, species richness, and soil condition were studied by the theory of multivariate statistical analysis based on the field data of low-quality forests in the forest regions of Xiaoxing＇ an Mountains. Main factors contributing to the low quality of the forests were identified. The changing process of the main factors was analysed and the parameters for the classification of low-quality forests were determined. The low-quality forests were then classified into five types, namely noncommercial low-quality forest, low-density and lowquality forest, low-quality forest with invading grass, low-quality forest with potential-productivity, and high-fertilization and low-benefit forest.
