Abstract:: 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 0.68~0.42 g/kg(0—5 cm),0.65~0.35 g/kg(5—10 cm)and 0.59~0.27 g/kg(10—15 cm), 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 caduciflora is 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, Zizania leaf w(TP) and sediment w(TP) are positively correlated, but the correlation is insignificant.
