The development and utilization of hot spring resource has been proceeded for hundred years in Taiwan, but their target was mainly focused on tourism and recreation. The characters of hot spring including high temperature and abundance minerals were not seriously considered. However, it has been widely applied in foreign countries, such as Japan, German and Hungary etc, Where their people could not only enjoy the healthy promotions and by-products from hot spring resource, but acquire much more economic benefits. Therefore, considering the abundance natural hot spring resource and great economic potential, the assessment and analysis in development of hot spring industrials has become the major issue in these days. The current study will collect the domestic and international hot spring information regarding category, classification criteria, and standards of examination techniques, and following categorize the hot spring water characteristics and associated applications. The investigations in Taiwan nineteen hot springs classification of hot spring water characteristics and establishing the scientific denomination standards of hot spring water characteristics will ascertain the various development foundation of hot spring industry. Furthermore, based on the classification results of hot spring water characteristics the study will review and examine the hot spring standards of Taiwan Hot Spring Laws to expect the laws more inclusive. Based on the classifications of hot spring water characteristics, this study will investigate the hot spring major application in rehabilitation and health care, enzyme-producing thermophilic bacteria, hot spring water activation and utilization, medicinal and biological techniques, and hot spring water purification and recycle, as well as other diverse uses. The results of current study will complete a comprehensive evaluation report of hot spring resources applications and the report will be a pilot study of hot spring industry innovation technology. Analysis and Assessment of health promotion and rehabilitation will be the major focus of this study. ]Based on the foundations of classifications of hot spring water characteristics, and hot spring industry innovation technologies, the current study will investigate the marketing development experience of domestic and international hot spring industries in order to master the total values of Taiwan hot spring industrial output, and by-products or technologies from hot spring resources, as well as complete a comprehensive evaluation report of future total values of hot spring industrial output, economic benefits, and government guidance mechanisms. The current will also draft the government verification guidance mechanisms of hot spring industry, complete hot spring water diverse applications and the intermediate- and long- term technical development strategies and information consulting platform in order to be the future fundamentals of both government and privates promoting hot spring industrial development.
