龙门石窟藻类类群调查分析

摘要

对龙门石窟潜溪寺、宾阳南洞、药方洞、西方净土变龛四个洞窟内淡水藻类的主要类群及分布情况进行了调查．结果显示，这些洞窟内的藻类包括蓝藻、绿藻、硅藻3个门中的6个科7个属，并对藻类的成因及其溶蚀岩石的机理进行了分析．研究结果将为以后生物病害防治办法的研究提供基础资料．%A preliminary investigation was made on the dominant communities and distribution of treshwater algae in the Hidden Stream Temple, the South Binyang Cave, the Remedy Cave and the Western Pure Land Change Niche in the Longmen Grottoes. The results showed that 7 genera of algae that belong to 6 families of Cya- nophyta, Chlorophyt and Bacillariophyta were found. The cause of algae breeding and the mechanism of karstifica- tion were also analyzed. These results will provide fundamental documents for research on the prevention and con- trol of biodeterioration in the future.
