| 摘 要： | 以川中丘陵区坡地防护林林地降雨量、径流量、泥沙含量等因子测定为切入点,借助侵蚀产沙数学模型,系统分析了不同防护林类型的降雨侵蚀力与产沙、降雨强度与产沙、次降雨下产流与产沙、地表径流与产沙以及不同防护林类型产流产沙的关系,同时通过对比分析,阐述了防护林体系中不同类型的产沙侵蚀过程和水土流失规律,为川中丘陵区坡地防护林结构的调整、控制水土流失和提高防护功能具有指导作用。 |
| 关 键 词： | 川中丘陵区 坡地防护林 侵蚀 产沙 |

| Abstract: | The rainfall, runoff, soil content in water on the hilly area of the central Sichuan basin have been stud- ied in paper, debited the mathematic mode forecasting the sand and soil eroding. There has been analyzed connec- tion to the differing forests types with by the numbers and synthetically. What's more, parallel synthesis the law of the loss about the sand and soil. It is studying the sand and soil loss that make protect the sand and soil on the hilly area of the central Sichuan basin, so the law can help farmers to change the protect forests in the future. |
| Keywords: | hilly area of central Sichuan basin protecting forests on slope erosion quaint of soil and sand |
