The basal diameter, height of aerial stem, leaf length at middle stem, leaf width at middle stem, internode length at middle stem, internodes number and panicle length of 30 plants from every population were recorded. The statistics of morphological characters showed that the distribution trends of the averages of morphological characters are similar among populations. However, the coefficients of variation within population of 7 morphological characters were very different. The CV of internodes was largest and the CV of height was smallest within population. F-statistics showed that the differences of all morphological characters among populations were significant (P.01). But the differences among populations were different between different groups. The cluster analysis proved that all populations could be divided into three types: salty reed, freshwater reed and giant reed.

From the analysis of the magnetic susceptibility,TOC,TN,pigment,organic car-bon isotope ,HI,saturated hydrocarbon and 14C dating etc. of the sediment samples from coresof two boreholes in the Taihu lake,a knowledge of the evolution of paleoenvironment of thelake during the last 14ka is achieved. The results show that the lake has undergone the fol-lowing stages .. The Lake was at a low level ,or even became exposed during 14.3-13.3kaBP,reflecting an arid climate. There existed a transitional stage during 13.3-12.4kaBP,the climate being slightly warm and wet. There are indications of a cold and dry climate around 11.5kaBP,probably corresponding to the Younger Drays event ,comparable with other areas in east China.
