摘  要:
基于银川平原湿地芦苇群落的一个生长季的调查,建立总生物量、单株生物量与密度指标的关联关系。结果表明:200株/m2左右是银川平原湿地芦苇群落的最适密度;超过这个密度区间之后自疏作用有所体现;生境中的有机质和速效养分含量越低,芦苇密度越大,显示了无性系植株的r型增殖方式;本研究对于芦苇湿地的保护和恢复中的合理密植有一定的指导意义。

摘  要:
Based on the survey in a growing season of Phragamites communis at Yinchuan plain wetland,relationships between total biomass,biomass of individual plant and density index were established.The results indicated that the most suitable density was about 200reeds/m2.When the density was more than this number,self-thinning would occur.The lower the contents of organic matter and available nutrients were in the living environment of the reeds,the higher density of reed plants would be,reflecting the r-proliferation way of the reed clones.The research presented guidance for reed wetland protection and the rational close planting during reed restoration.
