摘  要：
以滇东南岩溶湿地为研究对象,在普者黑湖滨湿地设置典型样地,采用典型样带法布点方式,探讨岩溶湖滨湿地在湖岸—湖心过程中沉积物全磷的空间变化规律以及与湿地挺水植物茭草全磷的关系。结果表明:(1)普者黑湖滨湿地沉积物w(TP)空间变化规律明显,水平方向总体按照湖岸—湖心方向依次递减,且变化范围分别为0.68~0.42g/kg(0—5cm),0.65~0.35g/kg(5—10cm)和0.59~0.27g/kg(10—15cm);垂直方向沉积物w(TP)均以表层最高,并依次向下层递减;(2)湿地植物茭草茎中TP含量沿湖岸—湖心方向总体呈现递减的变化规律,茭草叶对TP的吸收量明显高于茎的吸收量,且叶中w(TP)约为茎含量的1.35倍;(3)湿地植物茭草茎w(TP)与沉积物w(TP)均呈现出显著性相关性,茭草叶w(TP)与沉积物w(TP)均呈正相关,但相关性不显著。

摘  要：
The research site was the karst wetland in southeastern Yunnan,the typical sample sites were set in Puzhehei lakeside wetland by using the layout mode of typical sample method.The spatial variation of total phosphorus sediments in the process of lakeside—the middle of lake in karst wetland and the relationship of total phosphorus in wetland aquatic plant Zizania latifolia are discussed.The results show that:(1)the spatial variation of sediments w(TP)in Puzhehei lakeside wetland is obvious,from the horizontal direction,as a whole,it decreased regularly in accordance with lakeside—the middle of lake,from the vertical direction,and the ranges of w(TP)are 0.68~0.42g/kg(0—5cm),0.65~0.35g/kg(5—10cm)and 0.59~0.27g/kg(10—15cm),respective;the sediment of w(TP)is the highest on the surface,and decreases regularly to the lower level;(2)as a whole,the TP content in the wetland plant Zizania caduciflora shows the changing rule of decline,and absorption of TP about Zizania caduciflorais obviously higher than in stems,and the leaves of w(TP)are about 1.35 times of the stem;(3)the wetland plant Zizania caduciflora stem w(TP)and sediment w(TP)show a significant correlation,Zizanialeaf w(TP)and sediment w(TP)are positively correlated,but the correlation is insignificant.
