    福建典型人工林两栖动物生态位分析

    Niche analysis of amphibians in typical plantations of Fujian Province, eastern China.

    • 摘要: 2011 年69 月,在福建省将乐县国有林场不同林龄的人工林中,选择具有典型性的杉木纯林和杉木鄄马尾松 混交林2 种林型,分别设置3 块对比实验样地,采用围栏陷阱法冶对不同人工林植物群落特征和两栖动物生态位 特征进行研究。结果表明:1)人工林林龄对两栖动物生态位的影响高于人工林树种组成对两栖动物生态位的影 响,灌草层物种多样性规律和两栖动物生态位宽度规律一致;2)同科两栖动物间生态位重叠较大,竞争较为激烈; 3)两栖动物对人工林林龄变化的适应性和植物不同,在成过熟林中生态位宽度变窄、数量下降。

       

      Abstract: From June to September 2011, we had chosen 3 group pure plantations of Cunninghamia lanceolata in different ages and 3 group mixed plantations of C. lanceolata and Pinus massoniana in varied ages as samples, investigated the plant communities, and used the method of fence with pitfall trapto investigate amphibian communities. The results showed that: 1) the effects of forest age on amphibian niche were higher than those of species composition of plantations, and the biodiversity rule of shrub and herbaceous layer was same with the rule of amphibian niche width. 2) Amphibians in the same family had a high degree of niche overlapping and the competition was fierce. 3) The adaptability of amphibians to forest age change of plantations was different with plants, and in mature and over-mature stands, the niche width of amphibians became narrow and the number declined.
