摘　　要：通过对天山天池自然保护区径流小区的定位观测试验,采用数据统计分析的方法,对天山天池自然保护区草地坡地土壤侵蚀规律进行了研究。结果表明,(1)径流深随降雨量、降雨强度、坡度的增加而增大,而侵蚀量与降雨强度的关系比较明显;(2)植被显著地影响着坡地产沙量;(3)坡面径流深与降雨量、降雨强度、坡度之间的关系可以用多元线性回归函数很好地描述;(4)侵蚀量与土壤容重、径流深、降雨量、降雨强度之间的关系也可以用多元线性回归函数很好地描述。Through the located runoff plot observations in the Heaven Lake Nature Reserve of Xinjiang Wei Autonomous Region, soil erosion processes on sloping grassland were investigated. Results show that firstly, runoff depth increases with the increased rainfall amount, rainfall intensity, and gradient. The relationship between sediment and rainfall intensity is apparent. Secondly, grass has great influences on sediment yield on sloping grassland. Thirdly, the relationship among runoff depth, rainfall amount, rainfall intensity, and gradient can be well described by multiple linear regression function. Lastly, the relationship among sediment, soil bulk density, runoff depth, rainfall amount, and rainfall intensity can also be well described by multiple linear regression function.
