摘要
泥沙测验是水文测验的重要组成部分。本文对泥沙测验的方法和测验仪器的进展作了简述。悬沙测验新技术应用和测验精确度有较多的试验研究;推移质测验技术和仪器多年进展不大;床沙测验则基本没有变化。近年物理测验仪器在泥沙测验中得到应用,很有前景。遥感技术适于大尺度泥沙监测,并不断发展。观测数据实时传输、存储,整编、检索标准化是发展趋势。水文测站布局合理,站网密度控制有效,测验技术自动化、施测简便、提高保证率是未来的发展方向。
Sediment measurement is an important part of hydrometry.In this article,sediment measurement methods and instruments are briefly introduced.The new application and accuracy of suspended sediment measurement technology have been experimentally studied while the technology and instrument of bed load measurement have been made little progress for many years.The technology of bed material measurement has basically remained unchanging.In recent years,physical instruments have been applied in sediment measurement and they are very promising.The remote sensing technology is suitable for monitoring sediment measurement in large areas and is developing constantly.Real-time transmission,storage,integration,retrieval standardization of data are the development trend.The reasonable distribution of hydrological station,effective network density control,automated testing technology,simple methods and raising the guarantee rate are the future direction of development.
