通过坡面径流小区研究不同条件下的水土流失过程是森林水文研究的重要方法之一。目前,不仅在乌江中下游,而且包括南方山区的坡面水文计量,其资料不全,应用范围也有地区性。为此,我们在设计和修建合理可行的坡面径流小区的基础上,应用观察数据对不同地类条件下的产流进行比较和评价,为正确计量板桥河小流域综合治理后的水土流失奠定了基础。 It is one of the important methods to study soil and water loss under different conditions through slope runoff plot. At present, not only the mid-lower reaches of the Wujiang River, but also the slope hydrological measurement in the mountainous areas of the southern part of the country, the data are incomplete and the scope of application is also regional. Therefore, based on the design and construction of a reasonable and feasible slope runoff plot, we use observation data to compare and evaluate the runoff in different land types. In order to correctly measure the soil and water loss after the comprehensive management of Banqiao River catchment, Foundation.
