东山岛海岸带潺槁树林植物组成特征及主要木本种群生态位
Vegetative composition and niche breadth of plants in a Litsea glutinosa forest on Dongshan Island
摘要
Abstract
In order to reveal the resources utilization and relationship of different plant species in coastal wind-blown sand aera, based on the using of Shannon-Wiener and Levins formulas, The vegetative composition and population niches of important plants in a Litsea glutinosa forest on Dongshan Island were studied. Results indicated 34 plant species in the Litsea glutinosa forest including 23 woody species, accounting for 67.6％ of the total, belonging to 16 families and 22 genera with 11 herbs belonging to 6 families and 10 genera. Tropical and subtropical distributing were dominant in the vegetation. The layers of trees, shrubs, liane,and herbages could be distinguished clearly, Community structure showed the plant with the greatest niche breadth in the tree layer was L. glutinosa, and in the bush layer it was Sageretia thea; whereas in the herb layer dominant species were Ophiopogon bodinieri and A rthraxon hispidus. The niche overlap among populations revealed a resource sharing tendency from a stable community and offered some reference data for ecological development of forest defense system.
