本文对吉林省长白山天然赤松林更新种群的空间格局进行了描述,认为赤松更新种群星聚集分布格局;回归分析比较说明以及生态因子—更新三维图展示了生态环境对赤松天然更新的影响.同时,对不同年龄更新苗的存活现状及其原因进行了图示和论述.
In this paper, the spatial distribution pattern of natural Pinus densiflora population in Changbai Mountains in Jilin Province was described, and the star cluster distribution patterns of the regenerated population of Pinus densiflora were considered. The regression analysis, comparative analysis and eco-factor-update 3D maps showed that the ecological environment affected the natural regeneration of Pinus densiflora. Survival status of seedlings younger and younger at different ages and their causes were illustrated and discussed.
