摘要
对盐池中部沙地植物资源特征和生物多样性调查分析，结果表明：盐池中部沙地可分为缓坡沙地，硬梁地和低湿滩地3种。植物种类有105种，隶属29科，83属。在这3种沙化土地类型中，多度分布特征基本一致，即个体数量稀少的种和个体数量极多的种在群落中较少，中等多度即2～8个／m^2的种数量较多。物种的丰富度、均匀性、多样性变化基本一致，由高到低依次为硬梁地、缓坡沙地、低湿滩地，其计算结果与现场直观目测情况基本相吻合。在此基础上，并提出相应的保护措施。
Through investigation and analysis of plant resource characteristics and biodiversity in Yanchi middle sandy land, the results show： There are three kinds of sandy land in middle Yanchi, which are slight-slope sandy land, hard ridge and low, damp beach land; there are 105 plant species, which belong to 29 Family, 83 Genus; In the three sandificated land types, characteristics of abundance distribution are almost the same, that is to say, there are not many species with a very little number or with a very large number; most species have middle abundance distribution of 2-8/m^2 ; the change of species abundance, uniformity and diversity are almost the same, with hard ridge, slight-slope sandy land and low, damp beach land from high to low; this calculated result coincides with the observed fact. Finally, some protection measures and suggestions on how to conserve biodiversity in the area are put forward.
