坡地降雨入渗及产流是径流形成的主要环节,国内外水文科技工作者在这方面做了大量的分析和实验研究工作,取得了许多成果。黄土地区处于我国西北内陆,气候干燥,降雨产流影响因素极为复杂,且水文、气象资料条件甚差,因而开展室内控制条件下的水文实验是探讨本地区坡地降雨入渗产流微观机理的重要途径之一。我国在室内水
Rainfall infiltration and runoff on sloping land are the main links in the formation of runoff. Hydrological scientists at home and abroad have done a lot of analysis and experimental research in this respect and achieved many successes. The loess area is located in the inland of northwestern China with dry climate. The influencing factors of rainfall and runoff are extremely complicated, and the conditions of hydrological and meteorological data are very poor. Therefore, the hydrological experiment under the condition of indoor control is to study the microscopic mechanism of rainfall infiltration and runoff in the slope area One of the important ways. My country is in indoor water
