鄂西南川陕鹅耳枥种群结构与动态
|
摘要
基于鄂西南4个地段典型植被的调查数据,对川陕鹅耳枥种群结构与动态进行分析。结果表明:1)4个地段种群幼龄个体数量丰富,均属增长型种群;2)川陕鹅耳枥种群的胸径与树高呈显著正相关,胸径与树高异速生长明显;3)鄂西南种群死亡率和消失率均呈双峰型,在生长前期和中期达到高峰;存活曲线趋于Deevey-Ⅲ型,但各地段川陕鹅耳枥存活曲线在不同阶段呈现不同类型;4)生存分析表明,鄂西南川陕鹅耳枥种群总体呈现出前期锐减、中期稳定、后期衰退的特点。
Based on the survey data of typical vegetation in four locations in southwestern hubei, the population structure and dynamics of Carpinus fargesiana were analyzed. The results showed that 1) there were abundant young individuals in four locations, all of which were growth population.2) there was a significant positive correlation between the DBH and tree height of Carpinus fargesiana, and the growth rate of DBH and tree height were obviously different. 3) the mortality and disappear rate of Carpinus fargesiana populations exhibited as the bimodal distribution in southwestern hubei, and peaks at the prophase and metaphase. the survival curve tended to be the Deevey-Ⅲ type, But the survival curves of Carpinus fargesiana in different locations show different types in different stage.4) the survival analysis presented that the population of Carpinus fargesiana had the characteristics of slight decrease in the early stage, sharp decrease in the middle stage and decline in the later stage.
