Bifurcation analysis of a spatial vegetation model

作者:

Highlights:

• The existence of steady-state bifurcation emanating from positive constant solutions is established in a spatial vegetation model.

• Local and global structure of non-constant steady-state solutions are obtained.

• The impact of soil-water diffusion intensity on the occurrence of vegetation pattern is investigated.
