摘　　要：利用2004年秋冬季全国联网资料，给出中国19个典型区域大气气溶胶的光学厚度（AODλ-_500nm）、Angstrom混浊系数（β）和Angstrom波长指数（α）．结果表明，在青藏高原，海北、拉萨，AOD平均分别为0．09、0．12，β平均分别为0．05、0．13，α平均分别为1．09、0．06，东北地区，海伦、三江，AOD平均分别为0．14、0．15，β平均分别为0．04、0．06，α平均分别为2．32、1．58，北部的荒漠地区，阜康、沙坡头、鄂尔多斯，AOD平均的范围为0、17～0．32，β平均的范围为0．09～0．19，α平均的范围为0．68～1．28．森林生态地区，长白山、北京森林、西双版纳，AOD平均的范围为0．19～0．42，β平均的范围为0．12～0．19，α平均的范围为1．11～1．25．农业生态地区，沈阳、封丘、桃源、盐亭，AOD平均的范围为0．34～0．68，β平均的范围为0、18～0．38，α平均的范围为0．97～1．39东部沿海地区以及湖泊，胶州湾、上海、太湖，AOD平均的范围为0．49～0．68，β平均的范围为0.21～0．29，α平均的范围为1．24～1．37．内陆城市，北京、兰州，AOD平均分别为0．47、0．81，β平均分别为0．20、0．45，β平均分别为1．66、0．89．并对19个站点气溶胶的光学特性及其变化特征进行了分别论述。Atmospheric aerosol optical depth （AODλ-500nm ）, Angstrom turbidity coefficient （β） and Angstrom wavelength exponent （α） are obtained using the CERN sun hazemeter network from Aug to Dec, 2004. The results are as follows： At the Tibetan Plateau, Haibeiand Lhasa, the mean of AOD is 0.09, 0.12; the mean of β is 0.05, 0.13; the mean of α is 1.09, 0.06, respectively. At the Northeast of China, Hailun and Sanjiang, the mean of AOD is 0.14, 0.15; the mean of β is 0.04, 0.06; the mean of α is 2.32, 1.58, respectively. At the desert region of North China, e.g. Fukang, Shapotou and Eerduosi, the range of averaged AOD is from 0.17 to 0.32; the range of averaged β is from 0.09 to 0.19; the range of averaged α is from 0.68,to 1.28. At the forest areas, e, g. Changbai Mountain, Beijing forest and Xishuangbanna, the range of averaged AOD is from 0.19 to 0.42; the range of averaged β is from 0.12 to 0.19; the range of averaged α is from 1.11 to 1.25. At agriculture areas, e.g. Shenyang, Fengqiu, Taoyuan and Yanting, the range of averaged AOD is from 0.34 to 0.68;, the range of averaged β is from 0.18 to 0.38; the range of averaged a is from 0.97 to 1.39. At the littoral areas and the lake of East China, e.g. Jiaozhou Bay, Shanghai City and Tai Lake, the range of averaged AOD is from 0.49 to 0.68; the range of averaged β is from 0.21 to 0.29; the range of averaged α is from 1 .24 to 1.37. At the inland cities, Beijing City and Lanzhou City, the mean of AOD is 0.47, 0.81 ; the mean of β is 0.20, 0.45 ; the mean of a is 1.66, 0.89, respectively. The variations of aerosol properties at nineteen stations are explained in the paper.
