景观特征指数

      1)景观优势度指数模型:

              

 式中,为景观类型i所占景观比例;为斑块ij的面积;A为景观总面积。

       2)斑块密度模型:

              

  式中,N为景观中斑块数量;A为景观面积。

        3)边缘密度 模型:

             

  式中,E为景观中边缘长度。

        4)分维数模型:

             

  式中,为平均斑块分维数;为斑块ij的周长; 为斑块ij的面积;N为景观中斑块数量;m为景观类型数目;n为某类景观类型的斑块数量。

        5)景观多样性指数H模型:

             

  式中,为景观类型i所占面积的比例;m为景观类型数目。

        6)平均接近指数模型:

             

  式中,为离斑块ij指定距离内的同类斑块ijs的面积;为离斑块ij指定距离内的同类斑块ijs与斑块ij的距离;N为景观中的斑块数量。
