摘要: 通过生态位宽度和生态位重叠指数,结合TWINASPAN分类和DCA排序,研究北京首云铁矿自然恢复植物群落的主要物种的生态位的梯度变化,以及这些种的生态关系。利用调查数据筛选出9个主要种群进行分析,结果表明自然恢复群落中荆条的生态位宽度最大。比较不同种对的生态位重叠指数得出,种群生态位宽度越宽,与其他种群生态位重叠的机会就越大。TWINASPAN分类结合DCA排序对主要种群的生态位重叠进行分析,可以很好地反映种的生态关系,以及以这些种为优势种的群落的结构梯度和环境梯度。

Abstract: By using the niche breadth,niche overlap,TWINSPAN and DCA,the gradual change of the dominant species's niche of natural restoration vegetation and the relationship of communities have been studied. Based on the investigation of natural restoration community of mining wasteland in Beijing Shouyun Iron Mine,9 main populations were screened out for analysis of niche. The result showed that among the main populations the niche breadth of Vitex negundo was greater than that of other species. The results of niche overlapping showed that the species with big niche breadth will have niche overlapping with other species in the great opportunities. The result of DCA and TWINSPAN reflected the niche grade of the dominant species,the structure grade of and the environmental grade of community.

Key words: niche breath, niche overlap, TWINSPAN, DCA, natural restoration, Beijing Shouyun Iron Mine
