苔藓植物作为湿地公园的植物组成成分之一,开展其群落构建的研究,可为湿地生态系统管理和生物多样性维持机制提供重要理论依据。贵阳湿地和苔藓植物资源丰富,以贵阳市3个典型湿地公园为对象,研究苔藓植物的物种分布特征和环境因子,采用双向指示种分析(TWINSPAN)和典范对应分析(CCA)方法对苔藓植物群丛进行数量分类和排序。结果表明,贵阳市3个典型湿地公园有苔藓植物17科28属66种,其中,丛藓科(Pottiaceae)、灰藓科(Hypnaceae)、青藓科(Brachytheciaceae)为优势科;3个湿地公园苔藓植物β多样性差异较小,物种相似度高,丰富度低。苔藓植物分布的生境类型主要为石生与树生;生活型以交织型和丛集型为主。苔藓植物群丛类型可以分为13类,均有各自的特征,其物种组成和群落特征能较好的反映群丛类型与环境之间的关系,3个湿地公园的生境具有相似性。CCA分析结果表明,影响湿地公园中苔藓植物群丛分布的首要环境因子是海拔,其次是空气湿度,再次是郁闭度,光照也有一定影响。

A numerical model based on measured fictive temperature distributions is explored to evaluate the residual stress fields of CO_(2)laser-annealed mitigated fused silica damage *** proposed model extracts the residual strain from the differences in thermoelastic contraction of fused silica with different fictive temperatures from the initial frozen-in temperatures to ambient *** residual stress fields of mitigated damage sites for the CO_(2)laser-annealed case are obtained by a finite element analysis of equilibrium equations and constitutive *** simulated results indicate that the proposed model can accurately evaluate the residual stress fields of laser-annealed mitigated damage sites with a complex thermal *** calculated maximum hoop stress is in good agreement with the reported experimental *** estimated optical retardance profiles from the calculated radial and hoop stress fields are consistent with the photoelastic *** results provide sufficient evidence to demonstrate the suitability of the proposed model for describing the residual stresses of mitigated fused silica damage sites after CO_(2)laser annealing.
