摘　　要：基于太湖流域1992~2013年夜间灯光数据(DMSP-OLS),快速提取流域城镇建成区信息,并分析太湖流域不同时期城市建成区空间扩张特征。采用相关系数法、Spearman秩次相关系数法、Kendall秩次相关系数法及修正的Mann-Kendall(MMK)法分别对太湖全流域及各水利分区1951~2013年特征降水量进行演变规律及趋势性诊断分析。基于城市空间扩张分析成果,将太湖流域1979~2013年降水数据划分为2个时间段,即1979~2000年和2001~2013年,对比分析了不同城镇化时期内降水演变规律。Based on the DMSP-OLS data of Taihu Lake Basin from 1992 to 2013,the information of urban built-up areas in river basins was quickly extracted,and the spatial expansion characteristics of urban built-up areas in different periods of Taihu Lake Basin were analyzed. The correlation coefficient method,Spearman rank correlation coefficient method,Kendall rank correlation coefficient method and modified Mann-Kendall( MMK) method were used to diagnose and analyze the evolution and the trend of the characteristic precipitation in the Taihu Lake Basin and each water conservancy division from 1951 to 2013 respectively. Based on the analysis results of urban spatial expansion,the precipitation data from 1979 to 2013 in Taihu Lake Basin were divided into two periods from 1979 to2000 and 2001 to 2013. The precipitation evolution in different urbanization periods was compared and analyzed.
