This paper will define the conditons of recreational site asthe external and objective conditions tobe offered by recreational site, wich include resource development pattern, resource characteristic, accommodation facility, various recreational itineraries available and transportation situations. Due to the fact that the models for resource characteristics vary a lot, this paper will first utilize quantified model Ⅲ and cluster analysis method from multi-variate analysis methods to conduct classification, then quantified model Ⅰ will be used to examine the extent of impact that can be exerted by conditions of recreational site to recreational demand. Besides, this paper will also make use of the forty-two spots of sightseeing and recreational sites around Taiwan to perform empirical analysis, and the results indicate that the conditions of recreational site exercise tremendous effect on recreational demand, and the resource developement pattern and resource characteristic are most prominent.
