摘　　要：以经济社会较为发达的太湖流域为研究区,基于2007年流域内各省(市)的水足迹投入产出表,分析了3次产业的用水系数、水足迹和净外部水足迹。结果表明,2007年,流域内第一产业的完全用水系数最大,用水主要集中在直接用水方面;第二、第三产业用水主要集中在间接用水方面;2007年太湖流域水足迹为453.30亿m3,净外部水足迹为63.98亿m3,占全流域水足迹的14%。With Taihu Basin as study area,based on the water footprint input-output tables of 2007,water use coefficient,net external water footprint and water footprint of three major industries were analyzed.The results showed that：In 2007,the biggest completely water use coefficient is primary industry and the water use is mainly focused on direct water use ; The water use of secondary and tertiary industries are mainly concentrated in indirect water use ; In 2007,Taihu Basin water footprint is 45.330 billion m3.The net extemal water footprint is 6.398 billion m3and account for 14％ of whole basin water footprint.
