摘要
选择塔里木河下游喀尔达依断面,离河道不用距离的6个不同剖面进行粒度测试,并在相同距离进行植被调查,探讨土壤的粒度组成,及其与该地区地表天然植被种类及覆盖程度的关系.最终得出研究区表层土壤粒度随着地表林地面积的锐减发生较明显的粗化现象.为当地的农业土壤改良和防止土地沙化提供一些科学性的参考.
In the granular test,six different profiles of Kaerdayi Section of the lower reaches of Tarim River were selected and at the same distance,the vegetation was investigated,the soil particle composition and the relationship of the types and extent of the natural vegetation in the area were explored.Final results of the study showed that the surface soil particles were obviously coarsening along with the quick reduce of the woodlands.This research provided scientific reference for local agricultural soil improvement and the prevention of desertification.
