    摘要:

    [目的] 分析云南省公路上常用的水土流失量监测方法,为云南省公路建设期间水土保持措施的布设及防治措施效益的计算提供准确依据。[方法] 采用划分不同的地形地貌单元对公路进行水土流失量监测的方法,以云南省元江至红河二级公路元江段为例,在同等监测条件下,进行了常规监测方法和该监测方法的对比监测。[结果] 采用常规监测方法获得公路建设期间的水土流失量为102 058 t,采用监测方法所得的水土流失量为56 378 t,在对监测结果分析的基础上,可知采用该水土流失量监测方法的精度更高。[结论] 采用划分不同的地形地貌单元对公路进行水土流失量监测,可更好体现云南省公路建设期间水土流失发生的特点。

    Abstract:

    [Objective] This paper put forward soil erosion monitoring method for highway construction in order to provide basis for the layout of soil and water conservation measures and benefit calculation.[Methods] Taking Yuanjiang section on secondary road from Yuanjiang to Honghe in Yunnan Province as an example, a comparative analysis was conducted to reveal the differences between the conventional monitoring methods and the monitoring methods by dividing different topographic units under the same conditions.[Results] By applying the conventional monitoring methods, the amount of soil and water loss during highway construction was 102 058 t, while it was 56 378 t by applying the monitoring methods by dividing different topographic units. The accuracy of the monitoring method of soil and water loss by dividing different topographic units was higher, according to the comparative analysis.[Conclusion] Using different topographic units to monitor soil and water loss, can better reflect the characteristics of soil and water loss during the highway construction in Yunnan Province.
