Several targets, such as patch number, average patch area, form index of patch, fragmentation index, sub-dimension, heterogeneityindex of landscape and homogeneity index of landscape were studied.
The aggregate index that appears the variation magnitude and variation speed and the variation nature is proposed to describe quantitatively the variation nature and complexity of heterogeneity.
The author then proposes to develop an index of heterogeneity in time, perhaps in the following manner: Habitat, applying the numbers-1 of forest, o for meadow or savanna.
