This paper analyzes the spatial and temporal variety regulation of soil moisture and soil moisture characteristic constants on mobiledune in Horqin sandy land.
The results showed that the species of H. ammodendron community was the richest on low-lying land, the second on slow and gentle desert, and the least on semi-mobiledune.
结果表明，以平缓低洼地上梭梭群落的植物种类最丰富，其次是平缓沙地，半流动沙丘上的植物种类最少。
