摘　　要：利用植物对生态环境进行监测能综合地判断生态环境变化情况。通过对黔北丹霞地貌区、香纸沟喀斯特地貌区及烂泥沟卡林型金矿区苔类、角苔类植物的比较研究,统计分析种群的分布情况。结果表明,角苔类植物主要生长于生态环境保护较好的区域,扁萼苔科、角苔科为生态环境保护较好区域监测指示科植物,蛇苔属为生态环境保护较好区域监测指示属植物,小蛇苔、蛇苔为生态环境保护较好区域监测指示种植物。Eco-environment monitoring using plants can provide comprehensive information for determination of environmental changes. Through flora investigations of liverworts and hornworts in three substrates including Danxia Landform of north Guizhou province, Xiangzhigou Karst landform, and Lannigou Karlin Gold Mine, a close correlation was found between bryophytes flora and substrates. Hornworts mainly grew in the sites with better environmental protection. Radulaceae, Anthocerotaceae and Conocephalum could be used as indicators of better environmental protection at family and genus levels, respectively. Species of Conocephalum japonicum（ Thunb. ） Grolle and C. conicum （ L. ） Dum. may be used as direct indicators for sites with better environment conditions at species level.
