唐河流域发源地带山川植被覆盖面积较少,中游地处起伏不平的岗丘,间有大片平原,耕地较多,土质松软,每遇暴雨,水土流失严重,河水混浊。通过水文测验(泥沙测验),可以进一步掌握泥沙的运行规律,给治山治水、兴修水利、水土保持、城市供水、发展工农牧业生产提供准确的资料。 The origin area of ​​the Tanghe River Basin has a relatively small area of ​​vegetation covered by mountains and valleys. The mid-stream is located in a rolling hill with a large area of ​​plains with more arable land and softer soil. Each time a rainstorm occurs, soil erosion is severe and the river is cloudy. Through hydrology test (sediment test), we can further grasp the law of operation of sediment and provide accurate information for water treatment, water conservation, soil and water conservation, urban water supply and the development of industry, agriculture and animal husbandry.
