摘　　要：对塔里木盆地3个主要城市4种生态功能区空气负离子浓度监测。结果表明:(1)和田与喀什空气负离子浓度分别为303个/cm3和289个/cm3,明显低于库尔勒市(382个/cm3);(2)不同生态功能区间空气负离子浓度差异显著(F=27.061,P=0.000<0.001),顺序为林地(393个/cm3)>水体(375个/cm3)>生活区(291个/cm3)>商业区(241个/cm3);(3)各功能区空气负离子浓度日变化均表现为清晨和傍晚高于午间。方差分析表明林地、水体午间空气负离子浓度与清晨和傍晚的差异不显著,生活区和商业区差异显著;(4)不同天气状况下各功能区空气负离子均表现为雨天>晴天>阴天>沙尘(浮尘)。Air negative ion concentration in different ecological functional zones （ forest, water body, scenic spot, commercial zone and habitation zone） were monitored in different weather conditions in eight main urban of Xinjiang. Results showed that ： （ 1 ） Air negative ion concentrations in Hetian city and Kashi city were lower than those of in Kuerl city. （2）The difference of air negative ion concentration among individual ecological functional zones were significant（F =51. 960,P =0.000 〈0. 001 ）. Its order was forest （431 ions/cm3） 〉 scenic spot （398 ions/cm3） 〉 water body （397 ions/cm3） 〉 habitation zone （313 ions/cm3） 〉 commercial zone （270 ions/cm3 ） ; （ 3 ） In all of ecological function zones, air negative ion concentrations at noon were higher than those of at morning and at dusk. ANOVA analysis showed that differences in air negative ion concentration between noon and mor0ing and dusk were not significant in forest, water body and scenic spot, but the difference were significant in habitation zone and cgmmercial zone ; （ 4 ） Air negative ion concentration under different weather condition of individual ecological functional zones showed rainy day 〉 sunny day 〉 cloudy day 〉 dusk and sand day.
