以岩石裸露率在80%以上的贵州喀斯特高原区自然生长的圆叶乌桕作为研究对象,分析其种群的年龄结构和种群中的物种组成动态。结果表明:生态环境严酷、资源贫乏的喀斯特高原区,圆叶乌桕生长较好。但是种群内部的圆叶乌桕幼树较少,从森林演替的规律,圆叶乌桕最终被其它物种所代替。从喀斯特区生态环境治理和当地人民生活水平的角度考虑,圆叶乌桕是较为理想的先锋树种之一。
In order to analyze the age structure of the population and the dynamics of species composition in the population, the natural species of Radix Aconitum grown in Guizhou karst plateau with rock bareness above 80% The results showed that: the ecological environment is harsh, poor resources in the karst plateau area, the leaves are better growth. However, within the population, there were fewer saplings in the leaves, and from the law of forest succession, the leaves were eventually replaced by other species. From the perspective of ecological environment management and local people’s living standards in Karst region, Megalobrama australis is one of the more ideal pioneer tree species.
