景观结构分析模型

       1)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为景观类型的数目。

       2)优势度D模型:

              

  式中,=lg m,为最大多样性指数。

       3)景观的破碎度C模型:

               

  式中,为景观中所有景观类型斑块的总个数;A为景观的总面积。

       4)景观的分离度模型:

               

  式中,为景观类型i的分离度;为景观类型i的距离指数;为景观类型的面积指数;A为景观的总面积;为景观类型i的总面积;n为景观类型i中的斑块总个数。
