Résumé partiel
Rainfall redistribution in the canopy,especially the stemflow enrichment effect,is an ecological process mechanism for xerophyte shrubs to adapt to arid habitats.The study of the process and pattern of rainfall redistribution in the canopy of typical shrubs in the Mu Us sandy land(Hedysarum mongolicum,Caragana intermedia and Artemisia ordosica)has important theoretical significance for elucidating the ecological and hydrological mechanism of shrub pattern maintenance under the background of soil drought.Rainfall characteristics and morphological factors are the key factors that determine canopy rainfall redistribution and enrichment efficiency.The rain redistribution pattern and its influencing factors of the canopy of different species of shrubs,the stemflow and its collection rate of rainwater,and the influence of soil moisture were carried out respectively.The main research results and conclusions are as follows:1.Rainfall redistribution of three types of shrubsBy observing the redistribution phenomenon of rainfall by typical shrubs in the Mu Us sandy land(Hedysarum mongolicum,Caragana intermedia and Artemisia ordosica),the redistribution characteristics of the three shrubs under different rainfall and intensity were analyzed,To compare the adjustment effects of different shrubs in the redistribution of rainfall.
