摘　　要：沙棘根系有特殊的结构特点,这些结构特征决定了沙棘保水保土的效力,也直接影响了其周围土壤的理化性和微生物种类、数量、活性等。现通过分析沙棘根系的特点,研究其对土壤理化性的影响,以期对沙棘保持水土的能力进行分析,为沙棘的推广和研究提供实践指导与理论依据。Hippophae rhamnoides have partieuliar root system configuration, which conduce to the capability of Hippophae rharnnoides in holding water and soil, furthermore, which effect physical and chemic quality of near soil and animalcule＇s kinds, quantity and activity in it. This paper surveyed root characteristic of Hippophae rhamnoides and effect on physical and chemic ability of near soil, in order to analyze water and soil reserve of Hippophae rhamnoides, providing practice direction and theory gist for its spread and research.
