以长白山北坡野生蓝靛果忍冬群落调查数据为样本,对不同海拔蓝靛果忍冬种群空间分布格局特征进行分析比较,以揭示蓝靛果忍冬灌丛种群对环境的适应机理,从而为合理地利用和保护这一经济植物提供科学依据。结果表明:蓝靛果忍冬基株和克隆分株种群的分布类型为聚集分布,分布格局拟合为负二项分布;种群的聚集强度随海拔梯度变化呈双峰型曲线;种群格局规模在海拔1 200m和1 800m处较大,种群格局规模在海拔1 600m处最小。
Based on the survey data of Lonicera edulis populations on the northern slope of Changbai Mountain, the spatial distribution patterns of Lonicera edulis population at different altitudes were analyzed and compared to reveal the adaptation mechanism of Lonicera edulis population to environment, so as to reasonably utilize and protect This economic plant provides a scientific basis. The results showed that the distribution types of Lonicera edulis L. and clonal ramets were aggregated distribution and the distribution pattern fitting was a negative binomial distribution. The clustering intensity of the population showed a bimodal curve with the change of altitude gradient. The population size ranged from 1 200m and 1800m, and the pattern of population size is the smallest at 1 600m above sea level.
