摘要
2010年7月通过对南明河河流湿地不同地段苔藓植物进行野外调查、标本采集和初步鉴定,记载了苔藓植物共10科14属28种。优势科为真藓科(Bryaceae)、丛藓科(Pottiaceae)和青藓科(Brachytheciaceae)。真藓科(Bryaceae)和丛藓科(Pottiaceae)各占总数的25%;青藓科(Brachytheciaceae)占总数的18%。生活型含矮丛集型(57.15%)、交织型(28.57%)、高丛集型(10.71%)和平铺型(3.57%)4个类型。另外,调查显示苔藓植物种类在南明河从上游到下游呈逐步减少的趋势,推测与下游地区高强度的工业化和城市化过程有关。
By our preliminary investigation in July of 2010,twenty-eight species in ten families and fourteen genera are record from the different parts of the Nanming river wetlands.Bryaceae,Pottiaceae and Brachytheciaceae were dominat families.Bryaceae and Pottiaceae each account for 25 percentage while Brachytheciaceae for 18 percentage.There are four types of life-forms,they are short turfs（57.15%）,wefts（28.57%）,tall turfs（10.71%） and mats（3.57%）.In addition,The bryophytes species upper reaches to lower reaches in the Nanming River is slowly reduced.Industrialization and urbanization process maybe play an important role in biodiversity and distribution of bryophytes in river wetland of Guiyang city.
