Interactions of diffusion and nonlocal delay give rise to vegetation patterns in semi-arid environments
作者：
Highlights：
• We systematically presented a study on the influences of spatial diffusion and nonlocal delay on the vegetation patterns.
• It was found that the non-local water absorption intensity of vegetation roots can induce the phase change of vegetation pattern.
• The isolation between vegetation patches will be increased as that nonlocal water absorption intensity is enhanced.
• We revealed that increasing the feedback intensity of soil water diffusion or nonlocal strength within a certain range is helpful to increase the vegetation density.
