摘　　要：以位于松嫩平原西部连环湖的子湖泊小尚泡湖底沉积物为研究对象，对小尚泡沉积物粒度分形特征展开研究．研究结果显示：小尚泡的粒度指标具有分形特征，分形维数在2．365—2．529之间变动．小尚泡沉积物粒度分维值与中值粒径、峰态指标为负相关关系，而与分选系数为正相关关系．The sediments from Xiaoshangpao lake of Lianhuan lake in Songnen Plain fractal charaeteristies of grain sizes in sediments of Xiaoshangpao lake are analysed. West is studied. The The results show that the grain sizes of Xiaoshangpao lake have fractal characteristics. The fractal dimension of sediments ranges from 2. 365 to 2. 529. The fractal dimensions of the sediments in Xiaoshangpao Lake display a negative correlation with the median grains and kurtosis. The fractal dimensions of the sediments in Xiaoshangpao Lake display a positive correlation with the sorting coefficients.
