关于土壤侵蚀的计量,在我国迄今仍没有一套系统、通用的方法,特别是对于长江上游的乌江流域,以往的许多工作中主要是采用长江流域规划办公室的《关于水土流失等级划分标准表》作为评价土壤侵蚀的指标,在宏观上解决了乌江流域的水土流失评价和计量问题,对水土流失治理工作起了一定的作用。由于该“标准”涉及面广,不可能将各个地区的特点都表征出来,在某一地区、流域应用此“标准”评价水土流失状况时,其计量结果较
So far, there is no systematic and universal method for soil erosion measurement in our country. Especially for the Wujiang River valley in the upper reaches of the Yangtze River, many works in the past mainly adopted the “Standard Table for Classifying Soil and Water Loss Levels” of the Yangtze River Basin Planning Office As an indicator to evaluate soil erosion, it has solved the problem of soil and water loss evaluation and measurement in the macro-level and played a certain role in soil erosion control. Due to the wide scope of the “standard”, it is impossible to characterize the characteristics of each region. When a “standard” is applied to assess the status of soil and water loss in a certain area, the measurement results are more significant
