阴暗针叶林空间格局模型

       1)草本种多样性D模型:

                

  式中,表示第i中个体数在各个种个体总数中出现的概率。

        2)开敞度K模型:

              

  式中,为样点到各象限植株距离与其高度形成的仰角;h为各植株高度;d为距离。

        3)种群密度分布对光的选择性指数模型:

              

  式中,表示在第i资源位(在此为样方中的个体数);X为全部n个资源位中个体总和。

        4)生态位重叠之Ll模型:

               

  式中,表示x种第i个资源位中所有个体全部测度范围内出现的概率;为种y的概率;n同上。
