摘要
研究流域泥沙有利于分析泥沙来源、泥沙运动及河床演变等,采取有针对性的治理措施对控制泥沙非常有利。为此,根据分形理论,通过MS2000激光粒度分析仪分析了松花江流域晨明、古城子、哈尔滨、佳木斯、南岔、铁力、延寿七个水文站泥沙粒度分布的分形性。结果表明,松花江流域7个测站泥沙粒度的分维值在2.201~2.391之间,所对应的相关系数均在0.858以上,基本保持了良好的统计自相似性,分维值与泥沙颗粒组成、传统粒度参数的相关关系基本符合经验数据。
The research of basin sediment is beneficial to analyze sediment sources,sediment movement and fluvial process,and using targeted measures can better control the sediment.According to the fractal theory,MS2000 laser particle size analyzer was adopted to analyze the fractal characteristics of sediment particle size distribution of seven hydrologic which located in Songhuajiang River including Chenming,Guchengzi,Harbin,Jiamusi,Nantsa,Tieli,Yanshou stations.The results show that the fractal dimension value of basin sediment granularity is between 2.201-2.391 of the 7station,the corresponding correlation coefficient is above 0.858.The conclusion keeps a well statistical self-similarity basically.The correlation between fractal dimension value and sediment particle size distribution and the traditional size parameters is in line with empirical data.
