摘要
通过野外调查、定位试验和室内分析 ,探索了新疆和田扬沙、沙尘暴、大风和浮尘产生的原因及发生规律与土壤降尘量的关系及其时空变化特点。结果表明 ,和田地区的降尘受浮尘、扬沙、沙尘暴日数和强度的影响 。
A brief account on the causes and the mechanism of formation of raising sand,sand storm,strong wind,airborne dirt and the quantity of dustfall is given,the relationship among them analyzed,and the changes of quantity of dustfall in time and space explored through the field investigation,location test and physical and chemical analysis.The results illustrate that the dustfall in Hotan is influenced by days and intensities of airborne dirt,raising sand and sand storm and has important effect on the soil.
