采用IPA( Importance-Per formance Analysis)方法,以重庆市武隆县芙蓉洞为例,从游客角度,对其旅游解说系统的满意度进行研究.通过研究得出以下结论:(1)喀斯特洞穴拥有丰富的科学内涵,游客对导游解说的期望最高,希望导游在解说过程中以洞穴科学为主,将科学性与趣味性结合,以增强吸引力；(2)喀斯特洞穴中的解说牌示是游客自主游览的重要解说媒介,游客的关注度极高,希望其布局在恰当的位置,内容简明、准确、科学,图标符合国际惯例和国家标准,并注意外形与溶洞环境相协调；(3)喀斯特洞穴游客中心的使用频率较高,所处位置、外形、功能、特色服务等均会对游客的第一印象产生较大影响,是增强其整体满意度的重要因素.%Health effects of radon on the human body have always been a hotspot in medical, chemical, nuclear physical and some other researching area. In recent years, the academia have studied on the sources of radon (rocks and groundwater) . the influence factors of radon concentration (geologic factors, cave structure, meteorological parameters inside and outside the cave), radon concentration measurement (measuring object, measuring instruments and methods), the harm of radon, radon prevention and control (to isolate radon infiltration, enhance ventilation to reduce radon, reasonable arrangement of schedule to reduce the inhaled amount, strengthen monitoring) and some achievements have been got, but weak in the following researches such as the formation mechanism of radon in karst caves, establishment of karst cave radon measurement standards and effective dose estimates, controlling techniques of radon in karst caves and health management of show cave staff.
