| 摘 要： | 采用样线与样方相结合的调查方法，根据点相关系数及Ｘ＾２值连续性较正公式，测定了小兴安岭凉水自然保护区具有环境梯度的７个森林类型内主要蕨类植物的种间联结。结果表明：各林型均有其适生的蕨类类群，与该类群呈正联结的蕨类种其数量分布也多，反之刚少；具有环境梯度的不同林型序列，反映出蕨类植物适生生境的不同，据此，将本区主要蕨类植物分为４种生态类型。

| Abstract: | By the line intercept method and quadrat survey, according to correlation coefficient and x2 value continuance corrected formula.the interspecific association of the main pteridophytes in 7 forest type with an environmental gradient in the Liangshui Nature Sanctuary in the Xiaoxing'an Mountains was measured.The results showed that every forest type had suitable pteridophyte group and the pteridophyte species which was positively associated with the group had a lot of individuals and wider distribution.Various forest type sequences with an environmental gradient indicated that pteridophyte fit to various environment,therefore pteridophyte in the region could be divided into four ecological types. |
