Researches on Destination Marketing System (DMS) now still have problems addressed both in the fundamental theory and operation practice. This paper paid much attention to the operation and evaluation of DMS, in which Tourist Destination Image was introduced to help design a new evaluation module added to the system. In this module, tourist responded to a survey on tourist destination image to be a reference for evaluation. Besides, supplementary means were also designed to make it reasonable for tourists. In this way, solutions for evaluation and adjusting destination promotion through DMS are raised for enterprises and policy makers.
