水土流失的分析研究,是我们当前考查工作极关重要的问题。但在过去一段工作中,由于我们缺乏经验,一般的来说,多系情况多,分析研究少。为了克服这一缺点,把工作提高一步,兹节录第二查勘队报告一部份供大家参考。 The analysis of soil and water loss is a crucial issue for our current examinations. However, in the past period of work, due to our lack of experience, there are generally many cases of multi-departmental analysis and few studies. In order to overcome this shortcoming, we will take one step forward in our work and record some of the reports of the second survey team for your reference.
