The niche breadths of the populations of s. tsinyunensis are greatest in the communities we studied, which indicates the ecological adaptation of s. tsinyunensis is relatively stronger and the abilities of utilizing resources are greater. with the help of pianka ' s niche overlap we further studied the niche overlap among different species in the sampled communities. the niche overlap among the species with the same or similar environment requirements are greater, especially nich overlap between s. tsinyunensis and those with broad niche breadths in the communities are much greater
5 ）所調查的各群落中，縉雲黃芩的生態位寬度均較大，說明縉雲黃芩的生態適應幅度較大，對環境資源的利用能力較強；縉雲黃芩與群落中其主要伴生物種間的生態位重疊也較大，表明他們對資源利用的相似程度較高，導致縉雲黃芩與其它物種對某些資源的共同需求，在資源相對不足的情況下，生態位重疊較大的種間將會產生較為激烈的資源利用性競爭。 -
In this study, the niche characteristics of 12 main tree populations in ? castanopsis carlessii ? forest have been analyzed by quantitative method at the nature reserve of wuyi mountains, including niche breadth, niche proportional similarity and niche overlap

The results indicated that the greater the niche breadth of a species was, the stronger the ability of adaptation to environment and using resources was. the greater the niche overlap value for some species - pairs, the more similar the environmental requirements and resource use. the species with wide niche breadth may have high overlap value with species with narrow niche breadth, and low on the contrary
結果表明，種群生態位寬度越大，對環境的適應能力越強，對資源的利用能力也越強；生態位重疊越大，種群間的生態相似性越大，利用資源的相似性程度越高；生態位寬的種群對生態位窄的種群可能有較高的重疊值，反之則較低；生態位寬度最大的種群不一定為群落的建群種。 -
