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。
Abstract:
 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 200 reeds/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.
