摘　　要：针对云南省内较少关注的水面面积<30km2的小湖泊开展了调查工作,以调查所得的水质数据为基础,采用多因子分析方法和Arc GIS的统计分析方法,对云南省内的20个小湖泊的水质进行综合评价,并以评价结果为基础,结合Arc GIS的统计分析工具,进一步对云南省小湖泊的水质空间分布特征进行探索研究。结果发现,云南湖泊空间分布呈现出相对集中的特征,小湖泊水质状况也呈现集中分布的特点。滇东南片区的湖泊形成一个冷点区域,即滇东南三个湖泊的水质均较差。滇西北的大理和丽江区域形成一个热点区域,以茈碧湖为代表的湖泊水质总体保持较好。Yun - Gui plateau lake region is one of the five largest lake regions in China. Yunnan province has the most of the lakes among four provinces and cities in Yun - Gui plateau lakes. Much attention has been paid to those lakes with the water surface larger than 30km2 in Yunnan province. However, the small lakes have been neglec- ted. A survey on small lakes in Yunnan has been conducted. Based on the water quality data of twenty small lakes obtained during the survey, the water quality of these investigated lakes has been evaluated. Meanwhile, the spatial distribution of water qualities of these lakes was explored. Multivariate analysis based on SPSS 21.0 was borrowed to assess the water qualities of lakes. The statistic tools based on ArcGIS software were applied to explore the spatial distribution of water qualities of small lakes in a provincial scale. The results showed that Cibi Lake has the best water quality than other lakes. The water quality of Datunhai Lake ranks the last. The spatial distribution of small lakes in Yunnan was clustered geographically. The water qualities of these lakes indicated a clustered distribution as well. Three lakes in the south - eastern Yunnan formed a cold area, which meant that the water qualities of these lakes were all bad. However, Dali and Lijiang areas in the north -west Yunnan produced a hot spot, which indica- ted a cluster of all good water qualities of small lakes near each other.
