Gramineae and Compositae by the shifting sand to the fixed sandy land, the species of which changed greatly, that indicated they were playing a great role in the recovery of the sands. Asclepiadaceae plants could serve as a indicative plants to distinguish between the types of shifting sand and other sand; Portulacaceae and Bibgnoniaceae plants, which appeared only in the fixed sandy land, has become a landmark to determine the fixed sand plants. In addition to artificially plant Caragana spp. and Artemisia spp.

豆科和藜科植物作为流动沙地的先锋物种，表现出较强的适应能力；禾本科和菊科植物由流动沙地到固定沙地，其种类变化较大，表明其在沙地恢复中发挥着巨大的作用；萝摩科植物可作为区分流动沙地和其它沙地类型的指示性植物；马齿苋科和紫薇科植物仅在固定沙地中出现，已成为判断固定沙地的标志性植物。

In this paper,the erosional and depositional stability of the Lanjiang sand bar in the Longkou Bay is studied by making a comparison between water depth data in different periods,and the erosion and deposition mechanisms of the Lanjiang sand bar are discussed by analyzing the formation process of sand bar and the sediment movement around sand bar.
