福建北部马尾松群落生态位的研究

福建北部的马尾松林分布广，马尾松又是次生演替的先锋树种。本文采用定量分析方法，对马尾松群落生态位进行了研究。通过不同群落类型、不同海拔分布替代多维生态因子变化，调查样方替代资源位，以此计测群落各层主要种的生态位宽度与生态位重叠值。研究表明：通过定量的生态位分析，结果与自然规律相符合，有一定适用性，能作为进一步研究福建北部马尾松群落稳定性、演替、空间分布格局的理论基础，并对生产实践具有一定参考价值．

Study on the Niche of Masson Pine Community in Northern Fujian

Masson pine, the earlier successional species, wide distributes in northern Fujian, in this paper,its niche was analysed by quantitative method. The niche breadth and overiap of main tree species in masson pine community were measured by replacing multidimensional ecological factors with community types anddistribution types in different elevation, and by replacing resource dimensions with investigated plots. The results conformed the natural law, so it could provide theoretical basis for studing the stability, succession and spatial pattern of masson pine community in northern Fujian, and practical guadance for its management.
