摘　　要：根据2003、2009和2015年江苏太湖平原地区的水质数据分析其变化情况,并采用Spearman秩相关方法探讨了城镇用地对河流水质的影响。结果表明:江苏太湖平原地区城镇化进程迅速,且大部分为农用地转换而来;该地区河流水质整体呈现好转趋势;城镇用地占比与DO、TN质量浓度的相关系数在2015年最大,其中与DO质量浓度相关系数达到-0.633,城镇用地对水质整体状况有较大影响,且在2015年影响最大。According to the water quality data of Taihu Plain in Jiangsu Province in 2003,2009 and 2015,the changes were analyzed,and the influence of urban land on river water quality was discussed by Spearman rank correlation method.The results showed that the urbanization process in Taihu Plain of Jiangsu Province was rapid,and most of them were converted from agricultural land.The river water quality in the region showed an overall improvement trend.The correlation coefficient between the proportion of urban land and DO,TN concentration was the largest in 2015,and the correlation coefficient with DO concentration reached-0.633.Urban land had a great impact on overall situation of water quality,and the impact was the largest in 2015.
