Qingtu Lake is the tail-streams of Shivang River.The soil particle size distribution,the fractal dimension and the relationships between the fractal dimension of soil particle size and fractal dimension within the distance of 0-500 m of the edge of Qingtu Lake's surface were analyzed.The results showed that:the range of fractal dimension of soil particles in 0-20cm, 20-40 cm soil layer were 2.3708-2.8796 and 2.3590-2.7509 respectively. Fractal dimension of 0-20 cm soil layer had a slowly increasing trend in the range of 0-150 m and reached the maximum(2.8796)at 150 m,then it gradually decreased;Fractal dimension of 20-40 cm soil layer was slowly increasing within 100 m and at 100 m reached the maximum(2.7509);The soil fractal dimension had a significant negative correlation with sand content,and significant positive correlation with proportion content of silt and clay.Both the increase of particle content with diameter<0.05 mm and decrease of particle content with diameter>0.05 mm caused the increase of fractal dimension of soil particle size after the formation of water area.
