摘要：	岩溶洞穴空气CO_2变化影响次生沉积物沉积和溶蚀,它关系到洞穴旅游景观的稳定性及洞穴环境的舒适性,是岩溶作用发生的关键因素,进行洞穴空气CO_2变化的机制研究对于理解岩溶作用发生规律和现代洞穴合理保护具有重要意义.本文基于对我国南北地理分界区域河南西部鸡冠洞2011年12月至2016年5月近5年连续洞穴CO_2、水文地球化学指标、洞内外温度及湿度、大气降水和游客量等数据监测,并结合2016年5月19~20日洞穴CO_2等指标的昼夜的系统监测,分析了鸡冠洞洞穴空气CO_2时空变化特征和昼夜变化特征及其影响因素,结果表明:1在空间尺度上,越靠近洞口通风效应越强,洞穴空气p CO_2越低,越接近大气的p CO_2;洞穴结构及外界环境变化尤其是气候变化导致的土壤中p CO_2变化也会对鸡冠洞空气p CO_2变化产生影响.2在长时间尺度,鸡冠洞洞穴空气p CO_2夏季明显高于冬季,对比分析发现旅游活动和岩溶作用是其主要的影响因子.3在短时间尺度上(昼夜变化),鸡冠洞洞穴空气p CO_2变化主要受旅游活动的影响,建议景区在进行旅游开发的时候要考虑高峰期游客人数对CO_2的影响及岩溶景观的合理保护.
