ABSTRACT
The landscape index is a quantitative reflection of different landscape structural components and spatial pattern characteristics through highly concentrated landscape pattern information. The landscape pattern index can be divided into three levels: Patch metrics, Class metrics, and Landscape metrics, among which the patch level index is the basis for calculating other landscape indices, reflecting the landscape pattern by calculating the area, perimeter, number, shape and other characteristics of each patch in the landscape. There are differences in the landscape indices of different families of plants, the range of plant species involved in our study is small, and future studies can add different plant species as the dominant grassland communities. Also in future studies, the ecological implications of small-scale patterns should be explored under different vegetation cover, climate, soil, topography, and vegetation types.
