中文摘要：

对四川褔宝丹霞地貌地区苔藓植物进行了调查,采用重要值、多样性指数对其进行了物种多样性的研究,发现：12个样地内苔藓植物共35科55属108种,其中灰藓科是最优势的科.对该区12个样地进行了4个α多样性指数的运算,结果表明：位于转龙山的样地3,种数和Dahl丰富度指数都是最高的,样地10的Shannon多样性指数最高,说明样地10中苔藓植物群落的复杂程度高,群落所含信息量大.样地9的种数、丰富度和多样性都是最低的.总体来说,岩石基质生境（石壁、河滩）的α多样性高于土壤基质生境（毛竹林、阔叶林）.

英文摘要：

The investigationof bryophytesin FubaoDanxialandform districtin Sichuan was carried out with importance value and diversityindex tostudy its species diversity. It resulted that there were 35families,55 genus andl08speciesin 12 local quadrats, among which hypneceae was the most dominant. Through calculation of α diversityin 12 quadrats in the area, results were as followed. Quadrat3had the highest number of species and Dahlrichness index;quadrat 10had the highest Shannondiversity index. These indicatedthe high complexity and large information amountofbryophytecom- munityin quadrat 10. On the contrary, the species number, richness anddiversitylevels are the lowest in quadrat 9. Comparison of α diversity of bryophytesshowed that the diversity index of bryophytes were mainly affected by quad- ratspecies. Meanwhile, the altitude, human disturbance etc. had effects on the distribution of bryophytes. Inthe anal- ysis of bryophytes diversity in different habitats , the results showed that the diversity of rock habitat was higher than the diversity of soil habitat.
