摘　　要：本文通过调查黄龙风景区水体的环境地质特征与微生物群落结构及多样性,并与黄石公园对比分析,探讨了两种特殊地理环境下的微生物群落结构和多样性及其对钙华沉积的影响。结果表明:黄龙沟泉水属于地下冷泉,且景区内覆盖着大量植被,水体中有大量藻类和细菌;黄石公园猛犸象温泉区泉水属于地下热泉,植被覆盖率很低,泉水中微生物多为嗜热菌,藻类较少。黄龙与黄石钙华主要由方解石组成并且微生物参与了钙华的形成过程。微生物对钙华沉积的作用,主要分为模板作用、产物诱导作用和代谢调控作用,对比探讨了特殊地质环境下的微生物对钙华沉积的贡献,指出微生物沉积作用在钙华沉积过程中的重要性,可为黄龙钙华"黑化"防治提供理论依据。This paper analyzes the environmental geological characteristics and microbial community of the water body in Huanglong scenic area.By comparing relevant studies in Yellowstone National Park,the effects of micro‐bial communities on travertine deposition in two special geographical environments were discussed.By comparing Huanglonggou in Huanglong scenic area with the Mammoth Hot Spring area in Yellowstone National Park,it is found that Huanglonggou spring water belongs to underground cold spring with a lot of algae and bacteria,and the scenic area is covered with a lot of vegetation;While the spring water in Mammoth Hot Spring area belongs to un‐derground hot springs with low vegetation coverage,and the microorganisms in the spring water are mostly ther‐mophilic bacteria with few algae.In addition,the main components of Huanglong and Yellowstone National Park travertine both are calcite,and microorganisms are involved in the formation of travertine.The effect of microor‐ganisms on travertine deposition is mainly divided into template effect,product induction effect and metabolic regu‐lation effect.By comparing the effects of microorganisms on travertine deposition in special geographical environ‐ment,the importance of microbial deposition in travertine deposition process was pointed out,which could provide a theoretical basis for the prevention and control of"blackening"of travertine in Huanglong.
