| 摘 要： | 对3种不同环境条件下沙冬青人工种植试验和种群特征进行了研究,结果表明：不同生境下生长状况相比,荒山条件下沙冬青生长状况最好,固定沙丘其次,流动沙丘最差;出苗率和存活率荒山条件下的出苗率最高,固定沙丘出苗率其次,流动沙丘出苗率最差;不同生境的沙冬青种群在不同的坡位其分布格局不同,在整个荒山地区及固定沙丘地区的中部,沙冬青种群呈均匀分布,而在固定沙丘地区的上部和下部以及整个流动沙丘地区呈集群分布;荒山与固定沙丘在高度上与流动沙丘相比存在极显著差异。

| Abstract: | Ammopiptanthus mongolicus was planted on three different environmental conditions, and population characteristics were studied. The research results are as follows： compared to growth conditions in different habitats, the barren hills is the best, and the fixed dunes secondly, the moving dunes worst; as the rate of emergence and the rate of full stand of seedlings, the barren hills is the highest, the fixed dunes secondly, the moving dunes worst; The distribution patterns of Ammopiptanthus mongolicus population in different habitats are different in different slope positions. Ammopiptanthus mongolicus population is uniform distribution in whole barren hills area and in the middle area of fixed dunes, while in top and bottom of the fixed dunes area and the whole moving dunes is cluster distribution; there is a highly significant difference between barren hills and fixed dunes with moving dunes in height. |
