中文摘要	利用京、津、冀区域内所辖65个气象观测站1954-2002年的观测资料，分析了扬沙天气的气候变化特征。结果表明：京、津、冀区域绝大部分地区是扬沙灭气的主要影响区。高原、平原和匠陵地区是扬沙天气的多发区和易发区，宁晋、邢台一带是扬沙天气的高频区。扬沙的发生时问具有明显的季节变化特征；此区域内的扬沙呈现整体减少趋势，各分区域的变化趋势具有相似性，只是在减少幅度和年代际减少趋势上略有不同。
英文摘要	Although the disasters of blowing sands are slighter than that of dust storms, the blowing sands can cause wind erosion and environmental pollution, aggravate the land desertification, and are disastrous to the environment on which human rely for existence and to the social environment, and the atmospheric aerosols influence the climate change. Based on the available observation data from 65 meteorological stations in the Beijing, Tianjin and Hebei regions during the period from 1954 10 2000, in this paper, the climate change characteristics of blowing sands are analyzed. The results show that most of the areas of the Beijing, Tianjin and Hebei regions are affected by blowing sand weather. The blowing sand weather occurs frequently in the plateaus, plains and hilly regions. The seasonal change characteristics of blowing sands are obvious; the occurrence of blowing sands is in a decrease trend in these regions, however, the decrease amplitude and interdecade trend of blowing sands are slightly different from the different regions. The annual change of blowing sands is bimodal in the north regions but unimodal in the south regions.
