- 摘要:
- 在塔里木河中游地区，以典型植被类型选取样地，分层取得0～100 cm土壤样品并以此为研究对象，比较不同样地之间主要理化性质差异及变异性。结果表明：10个典型样地土壤的全氮、全磷含量偏低，全钾含量较高；各样地土壤容重显示出土壤比较紧实，结构性差，孔隙少，且各层之间有一定的差异性。各样境土壤的全氮、全磷、全钾变异系数呈现出的随着土层深入逐渐减小的样态。从该地区典型样地土壤主要理化指标的相关性来看，土壤含水率和土壤主要化学因子之间呈现明显的相关性，土壤容重也与大部分指标呈显著的负相关性，说明塔里木河中游地区，土壤的水分和紧实度存在地区差异和分层差异，对该地区其它理化指标都有一定的影响。
- Abstract:
- In the middle reaches of the Tarim River，the typical vegetation types were selected as plots，and 0-100 cm soil were stratified to obtain samples and as a research object，the difference and variability of main physical and chemical properties in different plots were analyzed.The results showed that 10 typical soil samples contained total nitrogen，total phosphorus content was low，and total potassium content was high;soil bulk density of samples showed the soil relatively tight，poorly structured，less porosity，and between the layers were some differences.Soil total nitrogen，total phosphorus，total potassium showed dropping off state with soil depth deep going.From correlation of soil physical and chemical indicators of tipical samples，showed significantly correlation of soil moisture and other major chemistry factor，soil bulk density and most indicators showed significant negative correlation，indicated there were regional differences and level differences in soil moisture and density in the middle reaches of the Tarim River region，and they impacted other physical and chemical indicators of theregion.
