This research was conducted in degraded rangeland at the southwestern edge of the Mu Us sandland, Yanchi county, Ningxia, the soil seedbank features and its relation to vegetation was analyzed using similarity analysis and ordination method, the results show that seeds within soil distribute mainly in 0~5 cm soil layer, less seeds in 6~15 cm soil layer in exclosed and non-exclosed rangeland, for seeds in exclosed soil, species richness and diversity index H are higher, while D is lower, exclosure measure, generally speaking, can increase plant species and amount of vegetation and seeds in soil, some annual plants, mesophytes and halophytes appears in the soil or surface.

以毛乌素沙地西南缘宁夏盐池县的退化草场为研究对象，采用相似性分析和排序方法对封育和未封育草场土壤种子库的特征及其与地上植被间关系进行了研究，结果表明无论封育区还是未封育区，土壤种子库中的种子主要分布于0~5cm的土层，6~15cm土层的种子数很少；封育区土壤种子库的物种丰富度大于未封育区，物种多样性则表现为H 值较大，而D值较小，总体上看封育措施可以提高地上植被和土壤中种子的种类和数量，一些一年生植物、中生植物和盐生植物开始出现在地面或土壤种子库中。
