摘要
塔克拉玛干沙漠石油公路沿线风沙活动是由塔木盆地内热能释放与冷空气入侵相互作用的结果。冷期，盆地内冷高压逆温作用较强，地面热能不足，使得风力和风沙活动强度弱；暖期，盆地内热源剧增，每当热能源饱和遇到冷空气入侵诱导，导致了强风及强风沙活动天气。可见，区内风沙活动及风成景观的塑造过程，主要是在暖干期进行的。
Sand drift activity along the oil transported highway in Taklimakan Desert is resulted from the interaction between internal energy giving off in the desert and external cold air mass intruding. In cold season, the temperature inversion from cold high pressure takes the charge of weaker sand drift activity. In warm season, the thermal sources increase fastly, and when saturated thermal sources meet the invasion of cold air mass, strong sand drift weather appears. So, it can be concluded that sand drift activity and aeolian landform forming are mainly taking place in warm dry period.
