Abstract: Based on the concept of Production-Living-Ecology Space, the Characteristic Towns of Tianjin are classified into three types: production type, life type and ecological type. The integrated development of the Production-Living-Ecology Space still faces the dilemma of imperfect industrial system, insufficient attraction of living space and great threat to ecological space. Based on the CAS theory, the integrated development mechanism of Production-Living-Ecology Space has been analyzed. Taking Shangcang as an example, the elements and characteristics of its Production-Living-Ecology Space were dissected and summarized. The Characteristic Towns of Tianjin should make the best use of resources, improve rural infrastructure construction and public services, and promote the quality of ecological space.

Key words: characteristic towns, Production-Living-Ecology Space, integrated development, rural revitalization strategy
