摘　　要：湿地植物群落的监测可为湿地公园的科学管理提供理论指导。本研究以贵州娘娘山湿地藓类沼泽为对象,比较了金发藓沼泽与泥炭藓沼泽植物群落特征,探索了群落优势种种间关系及群落多样性构成机制。结果表明,金发藓沼泽植物群落特征显示了自然恢复的良好成效,群落组成和结构逐步恢复。金发藓与蕨的优势度具有二次曲线关系,即较低优势度的蕨(<40%)促进金发藓的生长,较高优势度的蕨(>40%)抑制金发藓的生长。蕨类植物具有光竞争优势,抑制禾草状和非禾草状植物生长,显著影响植物群落多样性;非禾草状植物在植物多样性维持中具有重要地位。在湿地公园的管理中,合理控制蕨的生长有利于湿地水涵养功能和植物多样性保护。Plant community monitoring can provide theoretical guidance for the scientific management of wetland parks. We compared plant community characteristics between Sphagnum bog and Polytrichum bog and explored the interspecific relationships of dominant species and the mechanism underlying community composition. The results showed that characteristics of plant communities in Polytrichum bog showed a good efficiency of natural recovery,with the recovery of community composition and structure. The dominance of Polytrichum commune had a quadratic curve relationship with that of Pteridium aquilinum,in that P. aquilinum with lower dominance（ less than 40%） promoted the growth of P. commune and higher dominance（ more than 40%） inhibited the growth of P. commune. P. aquilinum had an advantage of light competition,inhibited the growth of graminoid and forb species,and then significantly affected plant community diversity.Forb species played an important role in the maintenance of plant community diversity. In wetland park management,reasonable control of P. aquilinum growth is conducive to wetland water conservation function and plant diversity conservation.
