景观格局指数

      1)景观多样性指数H模型:

              

  式中,k种景观类型占总面积的比;m为研究区中景观类型的总数。

      2)优势度指数D模型:

             

  式中,为研究区各类型景观所占比例相等时,景观拥有的最大的多样性指数。

      3)均匀度指数模型:

             

  式中,E为均匀度指数;H为修正了的Simpson指数;为在给定丰富度T条件下景观最大可能均匀度。

       4)景观破碎化指数模型:

            

  式中,为两个某一景观类型斑块数破碎化指数;为景观里各数斑块的总数;为景观数据矩阵的方格网中格子总数;为景观中某一景观类型的总数;为景观里各数斑块的平均斑块面积。

        5)斑块的分维数模型:

               

   式中,QL)为在观测尺度L上获得的某种量;D为量Q的分维数。

        6)聚集度指数模型:

                

  式中,为相对聚集度指数;C为复杂性指数;C的最大可能值;为生态系统i与生态系统j相邻的概率。
