采用GM70手持式二氧化碳测试仪等测量仪器,对兴文石海洞乡天泉洞内CO2浓度进行测量。根据对天泉洞2008年7、8月CO2浓度的实测数据资料,从高程、洞道横断面大小、洞道深度、游客等影响因素对CO2浓度分布的影响进行分析,给出了洞内CO2的分布特征。研究发现:高程对CO2浓度影响较小;洞道越深、洞断面越小,CO2浓度越大;游客对溶洞内CO2浓度贡献很大;目前洞内CO2浓度还不足以威胁到游客的身体健康。得出的结论和实测数据为保护游客身体健康和洞穴旅游开发管理提供了科学依据。
Using GM70 hand-held carbon dioxide tester and other measuring instruments, Xingwen Stone Cave Village Tianquan hole CO2 concentration measurements. According to the measured data of CO2 concentration in Tianquan Cave during July and August in 2008, the influence of CO2 concentration distribution on the elevation, the cross-sectional size of the tunnel, the depth of the tunnel, the tourists and other influencing factors is analyzed. Distribution characteristics. The results show that the elevation has little effect on the CO2 concentration. The deeper the cave, the smaller the hole cross section and the larger the CO2 concentration. The tourists contribute a lot to the CO2 concentration in the cave. At present, the CO2 concentration in the cave is not enough to threaten the health of tourists . The conclusions and measured data provided scientific basis for the protection of tourists’ health and the development and management of cave tourism.
