干旱区生态环境知识资源中心

An experiment was conducted to study the physiological and ecological characteristics of the main sand-fixing tree species in Horqin sandy land in order to explore the adaptabilities of tree species to semi-arid environment. The leaf water potential (LWP) and root distribution of ten sand-fixing tree species were measured and compared, and the preferred species were chosen for restoring degraded sand dunes in Horqin sandy land. These results are useful for evaluating the ability of the drought resistance of these species, and have some important implications for establishing artificial plantations that have high stability.
