Effects of Juniperus sabina L. and soil surface environmental conditions on stand structure of Artemisia ordosica Krasch. on fixed sand dune in semiarid area, China

Abstract

We investigated the effect of soil surface environmental conditions on the stand structure of Artemisia ordosica Krasch., which is a deciduous semi shrub and one of the revegetation plant in semiarid area, China. The effect of Juniperus sabina L., which has prostrate life-form and often distributed with A. ordosica was also considered. Individual density, position, size, existence of fruits, and soil surface conditions were measured. The results suggested that both species exclude with each other and the A. ordosica community on the fixed sand dune was influenced by the competition to get the resources with J. sabina rather than the nutrient conditions of soil surface.
