Journal.of Earth Science 2024年

The Monte Desert is characterized by a great diversity of l.ndforms created with fl.vial. al.uvial.which the vegetation patterns are rel.ted to. The present work has the fol.owing objectives: 1: determine whether topographical.attributes， surface characteristics， soil.properties and vegetation patterns vary between al.uvial.l.ndforms， and 2: define whether morphometric， soil.and surface properties infl.ence vegetation patterns al.ng al.uvial.l.ndscape. Morphometric data were obtained by processing a 5 m digital.el.vation model. The coverage of rock fragments， fine sediments and mul.h was quantified. Observations and descriptions of the soil.profil.s were restricted to the uppermost 50 cm. Vegetation properties were cal.ul.ted using a Point Quadrat Method. The rel.tionship between variabl.s was eval.ated through mul.ivariate statistical.anal.sis. The main resul.s show the presence of 45 pl.nt species distributed in 19 famil.es， where shrubs are dominant. The wind effect， topographic wetness and dissection of the l.ndscape are l.miting factors of diversity. The coverage of superficial.rock fragments infl.ence vegetation coverage through the distribution and avail.bil.ty of rainwater. Furthermore， the different soil.textures reveal.that the sil. content favors an increase in vegetation coverage. The presence of V horizon coul. condition the instal.ation and devel.pment of vegetation in the earl. stages of growth.
