| 摘 要： | 运用α多样性测度公式,探讨了不同干扰方式(Ⅰ.天然次生林、Ⅱ.择伐天然林种植木麻黄、Ⅲ.皆伐天然林种植木麻黄后实施保护、Ⅳ.皆伐天然林种植木麻黄后频繁干扰)对福建东山岛沙质海岸带植物群落的影响.结果表明,随着干扰强度和频度的增大,样地内科、属、种数均表现出先升高后降低的趋势;乔木层物种多样性和均匀度随着干扰强度和频率的...

| Abstract: | Based on α diversity index,the effects of different patterns of disturbance(Ⅰ: secondary forest,Ⅱ: planting Casuarina equisetifolia after selective cutting the secondary forest,Ⅲ: planting C.equisetifolia after clear cutting the secondary forest then protect to now,Ⅳ: planting C.equisetifolia after clear cutting the secondary forest then disturb the undergrowth frequently) of plants on sandy coast were analyzed.The results showed that with the increase of intensity and frequency of disturbance,the number of families and genera in communities increased at first and then downward,the species diversity and evenness in tree layer gradually reduced,and the dominance raised gradually,species diversity in other layers declined at first and then raised,the species diversity of undergrowth in community Ⅱ was higher than community Ⅰ,but keep higher similarity with natural community compared with other patterns of disturbance,The intensity and frequency of disturbance were the main cause of ecosystem degradation.It can maintain higher species diversity and community stability in coastal protection forest by building mixed forest with the use of indigenous plant and C.equisetifolia under moderate disturbance,and increase the season changes of community,these results provided basic materials for building a stable coastal protection forest system. |
