| 摘 要： | 对毛乌素沙地固定沙地不同地形（沙丘的顶部、迎风面、底部）中的沙地柏生物量进行比较,分析了土壤养分状况、土壤粒径与生物量关系。结果表明：迎风面的氮、有机质含量比较高,能够促进生物量的提高;天然沙地柏（土层深度〈50 cm）土壤颗粒组成均是以50-100μm的颗粒为主,生物量与土壤颗粒之间可相互影响。

| Abstract: | The biomass of Sabina vulgaris in different terrain of fixed dune was compared in Maowusu sandy land, and the relationships between the soil nutrients and biomass and the ones between the soil particle size and biomass were analyzed. The results showed that the content of nitrogen and organic matter in the windward side was relatively high, which can enhance the promotion of biomass. The soil particles （soil depth 〈 50 cm） of Sabina vulgaris were based on 50 - 100 um particles, the biomass can interact with soil particles. |
