1.雨量观测：育林沟不同坡度类型径流小区降水量采用试验场雨量站的资料。 2.泥沙取样及处理：径流、泥沙采用不同的观测设施，有分水箱、径流池，分水箱、径流池在降水结束、径流终止后立即读取径流池水位，根据分水箱、径流池面积、水位计算径流量；将分水箱、径流池泥水搅拌均匀取泥沙样，样品处置采用置换法。 3.土壤含水率：在具有代表性的固定地点，去除表层杂草后，在30cm深度取样，用烘干（称重）法测定。

Rainfall observation: the observation instruments for precipitation include SM1 ordinary rain gauge with diameter of 20cm and dsj2 siphon self recording rain gauge. The precipitation of runoff plots with different slopes is based on the data of rainfall stations in the test site.\n

  1. Sediment sampling and treatment: different observation facilities are adopted for runoff and sediment, including triangular weir, triangular groove, water distribution tank and runoff pool. Sand ocean is collected by triangular weir and triangular groove in the process of runoff generation; the water level of runoff pool is read immediately after precipitation and runoff is terminated, and runoff is calculated according to the area and water level of water distribution tank and runoff pool The sediment sample (500cm3) was taken by mixing water evenly, and the replacement method was used for sample disposal.

  2. Soil moisture content: in a representative fixed site, after removing the surface weeds, samples were taken at a depth of 30 cm and determined by drying (weighing) method.
