太统—崆峒山自然保护区内的崆峒山风景名胜区山惟一天然起源的针叶树种华山松,在区域植被恢复演替过程中天然更新能力较强。2012年9月中旬至2013年8月,保护区管理局组织技术人员,采用样地调查方式,设置临时样地36个,采集样地土壤、地形、坡向、乔木层、灌木层、活地被物等项因子数据进行对比分析研究。结果显示乔木层郁闭度对华山松天然更新效果影响极为明显,其次坡向、海拔2个自然因子对华山松天然更新影响也比较明显。

Natural Regeneration Research of Pinus armandii in Kongtong Mountains Scenic Area

Kongtong mountains scenic area located in the Taitong-Kongtong Mountains Nature Reserve, as the sole natural origin conifer, Pinus armandii has played an extremely important role in the process of recovery succession of regional vegetation. From the middle of September 2012 to August 2013, technical personnel organized by reserve administration used the methods sample-plot survey to survey and research following factor： habitat soil, topography, slope direction, tree layer, shrub layer and ground cover. Comparative analysis research was conducted after obtained the data of each factor.The results showed that crown density of tree layerhad significantly effecton natural regeneration of Pinus armandii,and slope direction and altitude have an obvious influenceon natural regeneration of Pinus armandii.
