It aims to research on tourism souvenir design under the background of characteristic town construction featuring the "trinity" of industry，culture and tourism. We firstly look into the construction of three respective examples of typical Chinese characteristic towns: Qingtian town, Longquan town and Baishanzu summer resort. Then we analyze and compare the difference between characteristic town souvenir. Design and traditional tourism souvenir design. Finally we put forward some new ideas of developing tourism souvenirs based on the combination of historical traditional industry and the "trinity". It points out that the elements of industry, culture and tourism should be taken into consideration when converting traditional tourism souvenirs into characteristic town souvenirs.
