森林自疏过程中密度变化规律的研究有利于改善生态环境,有利于林木的经营和管理。本文简介了森林自然稀疏的概念;根据-3/2自疏法则和-4/3自疏法则分析了森林自疏密度的变化规律;阐述了森林自疏规律模型的构建以及影响森林自疏密度变化的因素。
The research on the law of density change in forest self-sparse process is beneficial to improve the ecological environment and is beneficial to the management and management of forest trees. This paper introduces the concept of natural forest sparseness. According to the -3/2 self-thinning rule and the -4/3 self-thinning rule, the law of self-density of forest is analyzed. The construction of the law of self-density of forest and the influence of self-density of forest Factors of change.
