摘  要：
引进了具有经济性、便捷性、可操作性、重现性等优点的模拟降雨试验系统,在云南省坡耕地水土流失综合治理水土保持监测中进行实践和运用,研究坡耕地土壤产汇流规律和侵蚀规律。根据人工模拟降雨试验产汇流情况,统计张毕山、吉科等5个小流域坡地试验小区和坡改梯后梯地试验小区共59场次模拟降雨试验数据,分析坡改梯水土流失综合治理效果。结果表明,坡改梯后梯地土埂发挥了拦蓄雨量作用,强化了降雨入渗,提高了土壤含水量,降低了暴雨地表径流形成,土壤流失量和侵蚀强度得到了明显的缓减,蓄水保土效果较为显著。

摘  要：
A simulated rainfall experiment system was introduced,which was economical,convenient,feasible and reproducible,and it was practiced and applied in soil and water conservation monitoring in Yunnan Province,law of runoff yield and concentration of slope farmland was studied. According to the artificial simulation of rainfall runoff,the statistical simulation data of rainfall experiment terrace and slope residential district a total of 59 performances of small watershed slope terracing after experiment,the effect of comprehensive treatment of soil and water loss was analyzed. The results showed the soil slope to terrace ridge after the ladder played a role of rainfall interception,strengthened rainfall infiltration,improved soil moisture,reduced surface runoff formation. Soil loss and erosion intensity were significantly reduced,and the effect of water storage and soil conservation was significant.
