| 摘 要： | 在极端干旱的塔克拉玛干沙漠腹地 ,利用地下咸水灌溉建立人工绿地后 ,绿地土壤理化性质与流沙相比 ,变化很大。本文通过分析测定 ,结果表明 :绿地土壤细粒含量增加 :比重、容重降低 ,孔隙度 ,饱和含水量增加 ;在 5 0 cm剖面内盐分含量降低 ,但表层高于下层 ,p H增高 ,养分含量增加 ,肥力提高。不同植被类型和利用方式的绿地土壤理化性质有差异

| Abstract: | Artificial vegetation has been set up and irrigated by saline water in the center of Taklimakan Desert of the extremely anid region. Soil physico-chemical properties of artificial vegetation are very differeent from the drifting sand dunes. The results of testing the soil properties show: the plasmic material, porosity, saturated water content of artificial vegetation soil are add up; specific weight and volume weight are lower, salt content is lower than the drifting sand dunes in the profile form 0 to 50cm, pH and nutrient content increase. There are differences among the soils of different vegetation types and different use methods. |
