| 摘 要： | 选择了青海湖沙区的防沙区、流动沙丘及天然草地,对土壤的全N、全P、全K、pH值、有机质及土壤机械组成的分布特征开展研究,初步取得以下结果：治理区与流动沙丘的养分含量均较低。湖东、沙岛、鸟岛区的有机质含量属于强变异,沙岛的含磷量存在强度变异,其它指标均属于中等变异。生态监测站的天然草地有机质、含氮量及含磷量均高于克土、湖东、沙岛与鸟岛。青海湖沙区土壤呈碱性,各防沙区的沙土pH值均高于草地。鸟岛与克土的流动沙丘（0～30 cm）分别是细沙、中沙含量最高,克土的草方格内（0～30 cm）的粒度分布为中沙含量〉细沙〉粗沙。湖东种羊场的草方格与沙岛治理区（0～30 cm）的均表现为细沙〉中沙〉粗沙。生态监测站的围封天然草地（0～25 cm）粒径〈0.05 mm的土壤颗粒占绝大部分。

| Abstract: | The study selected areas of desertification combating around Qinghai Lake,and investigated soil nutrient,salt,pH value and soil mechanical composition,and made the preliminary results,the controlling area and mobile dune had lower soil nutrient.The organic matter in Sand Island,east Qinghai Lake,and Bird Island were strength variance.The content of P in Sand Island was strength variance,other indexes were intermediate variance.The contents of organic matter,N,P of grassland were higher than Ketu,East Lake,S... |
