本数据集为取样时段为2012年7月19日~2012年8月17日。取样点位置为黑河上游葫芦沟小流域原红泥沟出口附近，在取样点处挖了一个深度为2m的土壤剖面，然后在深度为60cm、90cm和140cm处各放置一个土壤水收集器。当土壤收集器收集到土壤水后，利用50ml一次性注射器抽取不同深度的管子就可取到不同深度的土壤水。此数据集包含三个不同深度土壤水的DOC值、氨氮值、二氧化硅含量以及阴阳离子值。

The sampling point was located near the outlet of hongnigou in hulugou small watershed in the upper reaches of Heihe River. A soil profile with a depth of 2m was excavated at the sampling point, and then a soil water collector was placed at the depth of 60cm, 90cm and 140cm respectively. When the soil water is collected by the soil collector, different depths of soil water can be obtained by using a 50ml disposable syringe to extract different depths of pipes. The data set contains doc value, ammonia nitrogen value, silica content and Cation Anion value of soil water at three different depths.
