兴文石海天泉洞CO_2影响因素分析

The analysis of CO_2 influence factors in Tianquan cave of Xingwen world Geo-park

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。

A Vaisala CARBOCAP Hand-Held Carbon Dioxide Meter GM70 was used to measure CO2 concentration in Tianquan cave of Xingwen world Geo-park.The study was done in Tianquan cave during July and August,2008.Data sources include the influence factors of distribution of CO2:elevation,tourists,cross section and depth of the cave.Results indicated tourists have strong impacts on the CO2 concentration,while no significant differences could be found among different elevation.Furthermore,significant correlation could be found between the depth of cave,the small cross section and the tourist's construction and the CO2 concentration.Those results indicate that the CO2 concentration in Tianquan cave has no threat to the health of tourists.The results and the data provide a scientific basis for the protection of people's health and the exploitation of cave tourism.
