摘要: The use of organic mulch is important for urban green applications. For areas in arid and semiarid regions receiving short high-intensive rainfall, rainfall characteristics, soil slope play an role functioning. These properties were studied. this purpose, simulation experiments using mulching conducted Jiufeng National Forestry Park to analyze the influence under different heavy events. results showed that water content displayed a decreasing tendency with increasing application. Compared bare soil, application 0.25 kg/m2 0.50 kg/m2 led maximum runoff decrease occurred mulch. Higher rate less greater runoff. amount generation decreased by 28-83% 21-83%, respectively, as compared soil. With 0.25-1.00 kg/m2, drainage accounted 56-60% total rainfall. Overall, efficient was found be 0.25-0.50 kg/m2. study are relevant experience
