摘 要：在科尔沁沙地的流动沙丘上采用不同的人工措施，即铺设秸秆栅栏沙障、草方格和栽植差巴嘎蒿，对沙丘的固定作用进行了研究。结果表明秸秆栅栏、草方格和栽植差巴嘎蒿都可显著增加沙丘植物的多样性和生物量，但草方格和栽植差巴嘎蒿好于秸秆栅栏沙障；沙地固定过程中，植被的演替顺序有沙蓬---差巴嘎蒿----狗尾草----黄蒿的趋势；植物生物量的形成与土壤湿度关系密切，应用试验数据建立了生物量(Y)与土壤湿度(X)的回归关系方程。

摘 要(英文)：Various measures, which were to erect stalk barrier, to set up checkerboard, and to plant Artemisia halodendrom, had been adopted for moving sand dunes control. After three years, the investigation indicted that those measures had increased significantly the plant diversity and biomass in plot, and the efficiency of checkerboard and Artemisia halodendrom were better than that of the stalk barrier. In the process of moving-sanddune fixed, the successive trends of vegetation was Agriophyiium quarrosum→Artemisia halodendrom→Setaria viridis→Artemisia scolaria; the formation of plant biomass was closely related to soil moisture of 0-20cm depth. And with the investigation data, a regress equation had been built between plant biomass (Y) and soil moisture (X) as follow.
Y =-13.7X2+72.5X-11.42 R2=0.824
