通过分析沙漠公路不同时段和地段风沙危害的特点 ,找出了从北向南风沙危害强度趋于减弱 ,公路及防沙体系受害程度逐渐降低的规律。注意到防沙体系所受风沙危害类型和程度在公路东西两侧和不同地貌部位差异明显。并且查明随着时间推移 ,公路受害面积扩大 ,重型沙害所占比例明显增长的公路沙害发展状况。 By analyzing the characteristics of sandstorm hazards in desert highway at different periods and locations, we find out that the damage intensity of sandstorm from north to south tends to weaken, and the damage degree of highway and sand control system is gradually reduced. It is noticed that the type and degree of sandstorm damage to the sand control system are obviously different on both east and west sides of the highway and in different landforms. And identify the development of highway sand hazard with the increase of the area affected by the highway and the significant increase in the proportion of heavy sands over time.
