摘要/Abstract

摘要：

红鳞蒲桃(Syzygium hancei)是广西滨海地带季节性雨林的优势种, 在修复滨海生态环境方面具有重要作用。该研究通过对防城港市3个群落的红鳞蒲桃种群(A、B、C)进行为期2年的幼苗存活数量动态监测, 编制红鳞蒲桃幼苗的动态生命表, 绘制幼苗存活曲线、死亡率曲线、生存函数曲线。主要结果有: 1) A、C种群幼苗存活曲线都趋向于Deevey-II型, B种群幼苗趋向于Deevey-III型, 死亡率曲线前期波动较大, 后期在0.2-0.4之间波动并逐渐平稳; 2)生存分析表明, A、B、C种群幼苗生存率均呈先升后降的趋势, 后期累计死亡率稳定高于生存率, B种群幼苗生存函数较A、C种群稳定; 3)综合分析表明, 3个野外红鳞蒲桃种群幼苗天然更新能力均低下, 相较之下B种群的天然更新能力最稳定。天然更新能力低下主要是由于幼苗萌发基数不大, 同时低龄幼苗死亡率较高, 且林下光照不足, 较少幼苗存活到下一个生长阶段。

Abstract:

Aims Syzygium hancei is the dominant species in the seasonal rainforests of the coastal zone of Guangxi. It plays an important role in restoration of the coastal ecological environment. Hence, investigating the population dynamics of natural S. hancei populations in Guangxi is of significant importance.
Methods In this study we monitored seedlings of S. hancei populations in three distinct communities (A, B and C) in Fangchenggang City over a period of two-years. Data on seedling survival rates were collected, and dynamic life tables were established. Survival curves, mortality curves, and survival function curves were constructed and analyzed.
Important findings Our results showed that: (1) The survival curves of populations A and C exhibited Deevey-II type characteristics, whereas the curve for population B displayed Deevey-III type characteristics. The mortality curves experienced substantial fluctuations during the early stage, but eventually stabilized, oscillating between 0.2 and 0.4 in the later stage. (2) Survival analysis demonstrated that the survival rates of populations A, B, and C followed an initial increase followed by a decrease. The cumulative mortality rate in the later period consistently exceeded the survival rate. Survival function fluctuations of population B were more stable compared to populations A and C. (3) The comprehensive analysis showed that all the natural regeneration capacities of those three S. hancei populations were low, with population B exhibiting the most stable capacity. The low natural regeneration capacity can be attributed to a limited germination base, high mortality rate of seedlings, and insufficient light, resulting in fewer seedlings progressing to the subsequent growth stage.

Key words: Syzygium hancei, population, seedling, dynamic life table, survival curve, survival analysis, natural regeneration capacity
