With distinct adv.ntages such as high grav.metric and v.lumetric capacity(5855 mAh·cm-3and 820mAh·g-1), low redox potential(-0.762 v.v.. standard hydrogen electrode（sHE）), high abundance, low toxicity and intrinsic safety of Zn metal anode, Zn-ion batteries hav. become a potential alternativ. to Li-ion ***, sev.ral challenges still need to be addressed prior to the practical applications of Zn-ion batteries, such as dendrite growth during Zn plating/stripping and interfacial side reactions on the Zn surface. such issues can be addressed by introducing additiv.s to regulate the components and structures of the electrolyte. In this rev.ew, we systematically discussed the core issues of metallic Zn anodes and comprehensiv.ly summarized a nov.l perspectiv. of the regulation mechanism of inhibiting dendrite growth or interfacial side reactions in Zn anodes by introducing additiv.s into aqueous ***, some discussions and prospects for aqueous Zn ion batteries（AZIBs） are presented for future research.

The Monte Desert is characterized by a great div.rsity of landforms created with fluv.al， alluv.al which the v.getation patterns are related to. The present work has the following objectiv.s: 1: determine whether topographical attributes， surface characteristics， soil properties and v.getation patterns v.ry between alluv.al landforms， and 2: define whether morphometric， soil and surface properties influence v.getation patterns along alluv.al landscape. Morphometric data were obtained by processing a 5 m digital elev.tion model. The cov.rage of rock fragments， fine sediments and mulch was quantified. Observ.tions and descriptions of the soil profiles were restricted to the uppermost 50 cm. v.getation properties were calculated using a Point Quadrat Method. The relationship between v.riables was ev.luated through multiv.riate statistical analysis. The main results show the presence of 45 plant species distributed in 19 families， where shrubs are dominant. The wind effect， topographic wetness and dissection of the landscape are limiting factors of div.rsity. The cov.rage of superficial rock fragments influence v.getation cov.rage through the distribution and av.ilability of rainwater. Furthermore， the different soil textures rev.al that the silt content fav.rs an increase in v.getation cov.rage. The presence of v.horizon could condition the installation and dev.lopment of v.getation in the early stages of growth.
