摘要: 采用3种常见的生态位宽度和生态位重叠计测公式,以外来种无瓣海桑扩散区的秋茄+桐花树群落演替系列作为资源轴,定量计测了几种红树植物的生态位宽度和重叠值.结果表明,各树种生态位宽度值排序为桐花树(3.8357)>秋茄(3.3421)>木榄(3.3180)>白骨壤(3.0975)>无瓣海桑(2.9137)>海桑(2.5724)>角果木(1.8523)>红海榄(1.6897)>海莲(1.0000),很好地表征了其生态适应性和分布幅度.各树种重叠值中,以秋茄、桐花树、木榄、白骨壤之间的生态位重叠较大,表明其间存在较强的资源利用性竞争.无瓣海桑生态位宽度处于中等程度,与中低潮滩红树植物海桑、桐花树、秋茄和白骨壤的重叠值相对较高,与红海榄、木榄有中度重叠,与角果木有少量重叠,与海莲完全没有重叠.

Abstract: Employing the succession series of Kandelia candel-Aegiceras corniculatum community in non indigenous species Sonneratia apetala extension area as resource axes,and with three commonly used calculation formulae,this paper determined the niche breadth and overlap of mangrove populations.The results showed that the niche breadth decreased in order of Aegiceras corniculatum (3.8357) > Kandelia candel (3.3421) > Bruguiera gymnorrhiza (3.3180) > Avicennia marina (3.0975) > Sonneratia apetala (2 9137) >Sonneratia caseolaris (205724) > Ceriops tagal (1.8523) > Rhizophora stylosa (1.6897) > Bruguiera sexangula (1.0000),which could indicate the ecological adaptability and distribution range of the species.The niche overlap among K.candel,A.corniculatum,B.gymnorrhiza and A.marina was the largest,suggesting the intense competition among them,followed by the niche overlap of S.apetala with S.caseolaris,A.corniculatum,K.candeli and A.marina,S.apetala with R.stylosa and B.sexangula,S.apetala with C.tagal,and S.apetala with B.sexangula.

Key words: Mangrove, Sonneratia apetala extension area, Tree species, Niche breadth, Niche overlap
