摘　　要：华北落叶松天然林结构属于随机分布,异龄林多树种混交,林分中分布有大、中、小径木和更新幼树,本文根据林分实际以优化林分空间结构,调节林分中主体种群与一般种群间的竞争态势,提高林分质量,丰富林分多样性,实现森林结构稳定、林地林木能持续利用,种群更替保持良性健康。以森林的多种功能发挥为目标,论述了调控林分空间结构的技术与方法。The natural forest structure of Larix gmelinii in North China belongs to random distribution,mixed multi-species of uneven-aged forests,large,medium and small-diameter trees and young trees are distributed in the stands.According to the actual situation of the stands,this paper optimizes the spatial structure of the stands,regulates the competition situation between the main population and the general population,improves the quality of the stands,enriches the diversity of the stands,and achieves the stability of the forest structure and forest trees on the forest land.In order to make full use of the multiple functions of forest,the techniques and methods of regulating and controlling the spatial structure of forest stand were discussed.
