• 中文摘要： 本文係依據1976年臺灣各地區氣象資料，分析大氣穩定度、混合層高度，以及混合層間之平均風速，並推算各地區之環境擴散指數。 從分析結果顯示在分析大氣穩定度時，使用於較長期之擴散式者以Pasquill法為佳，短期者以Stoner法較宜，但須檢討風速儀之靈敏度及安裝環境之代表性“ 在環境擴散指數分析結果，嘉義及鹽寮（宜蘭附近）等地區之擴散潛勢較差。
• 英文摘要： Analysis of the atmospheric stability, mixingheight and the average wind velocity under themixing layer was made according to the meteor-ological factors in 1976, which were obtainnedfrom several observatories in Taiwan area. Also,the environmental dispersion parameters in everyregions over Taiwan area were calculated withthe above data. The results show that the long-term disper-sion was suitable to Pasquill method, and theshort-term was available to Stoner equation inthe analysis of atmospheric stability. But theinstrument sensitivity and installation locationof anemometer must be considered. In this paper, the dispersal parameters ofChinsan, Taipei, Hsinchu, Wuchi, Chiayi, Tainan,Kaohsiung, Yenliao, Hwalien and Hengchun areobtainned from this investigation. Comparingthese results, it could be understood that theenvironmental dispersion potentiality in Taiwanarea was excellent, except Chiayi and Yenliao.
