Keyword:  土壤性状植被类型黄河三角洲;
Abstract: 黄河三角洲是海陆交互作用形成的退海地,土壤形成时间相对较短,地面植被演替频繁,整个生态系统比较脆弱.黄河三角洲植被演替的过程也是植物适应环境、改造生境的过程,对土壤盐分和水分的忍耐力决定了植物适应生境的能力.详尽分析了不同植被类型和不同土地利用方式与土壤性状的相互关系,以揭示黄河三角洲生态系统演进过程中土壤特征的变化规律,反映植被演替与土壤演替的相关关系.结果发现:不同植被类型下土壤中盐分、有机质、N、P等含量及土壤的机械组成都表现出一定的规律性,说明人类对土地的利用方式受土壤性质的制约,不同的土地利用方式反过来也会对土壤产生影响.
