| 英文摘要 | Mosses have been recognized as a useful tool for biomonitoring atmospheric deposition and assessing regional environment. this study was carried on whether the same moss growing in areas with identical regional atmospheric deposition while under different growing environments would have the same indicating signals. similar variations in mean delta c-13 and delta n-15 signatures were found between mosses collected from five habitats, with an increasing sequence from mosses under canopies to epilithic mosses, indicating that habitats were potentially regulating delta(13) c and delta n-15 values of mosses. dryer habitats (lower water availability) and input of more aerosol n were the main reasons for higher delta(13) c and delta n-15 values of mosses at open sites (especially for epilithic species), while more negative values of mosses under canopies were attributed to their wetter habitats and less uptake of aerosol n. additionally, delta n-15 values not delta c-13 varied linearly with canopy thickness from -7.84%. (1 in) to -4.71 +/- 0.7%. (4 m), suggesting 615 n was more sensitive for indicating canopy retention. consequently, isotopic data of mosses under different environments could not be compared for atmospheric deposition research with each other even collected at the same site. moss 613 c and 615 n were affected not only by regional atmospheric n sources but also by their growing environments. 615 n of epilithic haplocladiurn microphyllum at open sites can be taken as confident bio-indicator of atmospheric n deposition, which would deepen the application of stable nitrogen isotope of bryophytes in atmosphere-plant system study.
