从区系、外貌、结构和动态等四个方面对福建南靖和溪的毛竹林作了群落分析,并讨论了其群落生态学特征。研究结果表明,闽南毛竹林的区系组成以热带科属为主,物种多样性指数D达4.6353~4.8742,均匀度J达62.93%~73.27%,其Shannon-Wiener指数与亚热带常绿阔叶林相当,表明毛竹群落中物种较丰富。其生活型谱为高位芽植物60%>地下芽植物13%>地上芽植物11%>一年生植物10%>地面芽植物6%,叶的性质具有中型叶多、草质叶多和单叶多的特点,其结构较简单,演替趋势较稳定,群落分析表明,在人为干扰下,毛竹林是亚热带地区较稳定的植被类型,可以对此加以合理利用。
The community structure, appearance, structure and dynamics of four areas from Fujian and Jiangxi Creek and bamboo forests made a community analysis, and discussed its ecological characteristics of the community. The results showed that the flora of Moso bamboo forests in southern Fujian was dominated by the genus Tropaeae. The species diversity index D was 4.6353-4.8742, and the evenness J was 62.93% -73.27%. The Shannon-Wiener The index is comparable to that in the subtropical evergreen broad-leaved forest, indicating that species are abundant in the moso bamboo community. Its life spectrum is high with 60% of sprout plants> 13% of underground sprout plants> 11% of sprout plants> 10% of annual plants> 6% of sprout plants with more medium leaves, more grassy leaves and more leafy leaves The structure is simple and the trend of succession is stable. Community analysis shows that Moso bamboo forest is a relatively stable type of vegetation in the subtropical area under man-made disturbance and can be reasonably utilized.
