摘要

【目的】江苏宝华山地处亚热带北缘,青冈为其森林群落的重要组成树种。对青冈种群动态进行研究,可了解该地区常绿落叶阔叶混交林的演替动态,同时为森林保护策略的制定和人工林的演替促进提供理论指导。【方法】在宝华山设置1 hm²的固定样地,对样地内 432 株青冈个体进行定位并每木检尺; 根据胸径大小将其划分为 10 个径级,采用径级结构代替年龄结构探讨了该物种的种群动态; 采用点格局方法(Ripley’s K-Function)对其空间分布规律进行分析。【结果】青冈种群径级结构呈类倒“J”形,自然更新良好,属增长型种群; 个体的最高和最低死亡率分别出现在第 5 和第 6 径级,存活曲线接近于 Deevey-Ⅱ 型; 随研究尺度增加,青冈种群呈现由集群分布、随机分布到均匀分布的变化,而不同年龄段个体的变化规律略有差异,幼树、小树、中树和大树随空间尺度加大,变化规律同种群一致,老树则多呈随机分布。【结论】青冈在北亚热带常绿落叶阔叶混交林中有较强的适应能力,种群可长时间维持稳定的状态。为促进宝华山乃至整个宁镇山脉人工林向更加自然稳定的方向发展,建议人工抚育时,适当补植青冈幼苗,促进林分更新。

Abstract

【Objective】 The Baohua Mountain in Jiangsu Province is located on the northern edge of the subtropical zone, and Cyclobalanopsis glauca is an important component of its forest community. By studying the population dynamics of C. glauca, we can understand the succession dynamics of evergreen deciduous broad-leaved mixed forests and provide theoretical guidance for the formulation of forest protection strategies and promotion of succession in artificial forests. 【Method】A permanent one-hectare forest plot was established on the Baohua Mountain. A total of 432 C. glauca individuals with diameter at breast height(DBH)≥ 1 cm were measured, ranked into 10 diameter classes according to the DBH, and the age structure replaced by the diameter structure to discuss the population dynamics of C. glauca. The point pattern method(Ripley’s K-Function)was used to analyze the spatial distribution pattern. 【Result】The demographic structure of the C. glauca population follows an inverted “J” shape, suggesting a high regeneration rate and rapid growth of young individuals in this population. The highest and lowest mortality rates were detected in classes 5 and 6, respectively. The survivorship curve of the C. glauca population was close to the Deevey-Ⅱcurve. With an increase in the spatial scale, the distribution patterns of the C. glauca population fluctuated from random to clustered and then to uniform. The variation rules of the individuals in different age groups were slightly different. The distribution patterns of saplings and young, middle aged, and mature trees were characterized by a “clustered-random-uniform” change series as the spatial scale increased, whereas they were random for the old trees.【Conclusion】In the north subtropical evergreen deciduous broad-leaved mixed forest, the C. glauca population can maintain a stable state for a long time because of its strong adaptability. For natural and stable succession in artificial forests on the Baohua Mountain, and even the entire Ningzhen Mountain Range, artificial cultivation of C. glauca seedlings can be performed to improve the internal structure and promote regeneration of forest stands.
