With the continuous development of society, as a transitional level between rural and urban areas in urban system, towns are facing a series of problems such as ignoring ecological environment, unreasonable planning content and lack of public space. In this paper, from the perspective of "urban catalyst", taking Jingfu town of Santai County as the research object, the concept of catalyst is introduced by investigating the existing problems of the site and respecting the local natural and cultural environment. It has a certain reference value for the activation and development of urban and rural towns to integrate and update the site resources, select the appropriate space of catalyst to promote the activation of surrounding areas, and promote the sustainable renewal of small towns through the framework of catalyst space system.
