摘要: 宁夏沙坡头地区的气象观测现存的资料已有十三年, 本文对该地区多年来的风向、风速的年、季、月变化状况进行分析, 特别对近几年来起沙风风信状况的观测资料作了详细的分析, 以了解本地区风沙运动的季节性特点和风沙运动与下垫面季节变化的关系, 为铁路沙害的防治提供基本资料。

Abstract: The meteorological data of Shapotou Area for 13 years are available. The paper analyzes the yearly, seasonal and monthly variations of wind direction and wind velocity in the area for recent years, and the observation data of threshold wind in particular. These analyses can help us understand the seasonal characteristics of wind-drift sand and the relation between wind-drift sand movement and seasonal change of underlying surface, and provide some basic information for sand control along railway.
