摘    要:利用计盒维数和信息维数两种分形方法分析了黄河三角洲湿地柽柳种群的空间分布特征及其随水深梯度的变化。结果表明,不同水深梯度下柽柳种群分布格局的计盒维数均较大,随着水深的增大而逐渐减小,但变化幅度较小,反映了不同水深梯度下柽柳种群对水平空间的占据程度较大;信息维数总体上随水深的增大而减小,在水深低于-1.55m范围内,信息维数较大,柽柳种群的微观结构较为复杂,格局强度较高,水深高于-1.55m时,信息维数较小,柽柳种群的微观结构较为简单,格局强度较弱。水深-1.55m可能是黄河三角洲湿地柽柳种群分布格局的一个阅值。

关 键 词:柽柳  分布格局  计盒维数  信息维数  湿地  黄河三角洲
