In recent years, with the abnormal global climate change, the problem of desertification has become more and more serious. The vegetation pattern is accompanied by desertification, and thus, the study of the vegetation pattern is helpful to better understand the causes of desertification. In this work, we reveal the influences of hydrotropism on th...

Context 1
... soil water distribution in these areas is uneven, forming a moisture gradient. In response to a moisture gradient, the roots of vegetation will show the characteristics of hydrotropism to get more water for basic life activities (Figure 1). ...

... structure observed in the nature and pattern structure obtained by numerical simulation. Fig (a 1 -d 1 ) shows realistic vegetation pattern structures: (a 1 ) Zambia, spot vegetation structure [4]; (b 1 ) Niger, mixed vegetation structure [27]; (c 1 ) Niamey and Niger, stripe vegetation structure [12]; and (d 1 ) SW Niger, gap vegetation structure [4]. Fig (a 2 -d 2 ) shows corresponding numerical simulation patterns. ...
