摘要
分析四川境内41个水文站（区间）1130站年实测悬移质泥沙资料和相应水文站控制流域内土地利用资料，从流域产沙机理出发，建立了经验关系，以用于无泥沙测验资料地区推求河流多年平均含沙量。
The paper analyzes the measured suspended sediment data from 41 gauging stations in Sichuan during 1 130 station-years and the land use data within the controlled catchment areas of corresponding gauging stations. From the pointview of sediment formation mechanism in basin,the empirical relationship is established for the derivation of mean annual sediment content in rivers without sediment data.
