  3. Spatial distribution and time scales of atmospheric diffusion over beijing area are revealed by means of a random walk simulation model and practical meteorological data with a specified emission source from the city. results show a southward transport pattern for wintertime while a northwest transport of pollutants in summer. the area is the least evidently influenced by the emission source in spring, while the largest in autumn. the time spent for instantly emitted material removing from the model domain varies from winter - spring to summer - autumn. the former was shorter one of less than 20 hours ; the latter was longer one of approximately 30 hours. distribution of occurrence probability for different removal times was not symmetry. reducing slowly at the end of longer removal time, probability exists for pollutants remaining in this area a long time

    結果表明，冬季示蹤物偏南夏季偏西北的輸送明顯春季擴散影響范圍最小秋季最大。示蹤物從200km200km模式區域輸出的平均時間去除時間明顯分為冬春季和夏秋季兩組，前者較小，平均在20h以下，後者較大，平均約30h 。不同去除時間出現的頻率分佈是非對稱的，在長去除時間一側，出現頻率下降緩慢，顯示污染物有在該區域內長時間滯留的可能。
