| 摘 要： | 生态位理论是现代生态学中的一个重要内容,现正日益受到人们的重视。多维生态位概念提出之后,这方面的研究又有了新的发展。生态位定量描述主要包括两方面:一是生态位宽度(Niche Breadth),即被某一生物种所利用的各种不同资源的总和。其次是生态位重叠(Niche Overlap),即几个生物种共同分享或竞争一个已知栖息资源的程度。这两个方面的测定可反映出群落中各个物

| Abstract: | Spatial niche of Six main species of spiders Pardosa pseudoannulata,Pirata
subpraticus,Coleosoma octomaculatum,Ummeliata insecticeps,Neoscona sp.,Tetra-
gnatha sp.in rice fields was discribed according to the investigation of their
special habitate and the indices of niche breadth and niche overlap were measur-
ed in this paper.The measure indices of niche before were mostly on one
resource dimension and a multidimension indices of niche breadth was suggested.
Furthermore,several measure indices of niche were compared. |
