Environmental assessments typically require fine- or high-resolution datasets, example of which the Environmental Change Network (ECN) provides. This study has therefore taken advantage of the free access to the datasets to investigate temporal characteristics of precipitation and soil water chemistry, and relationship between the concentration of selected chemical variables in precipitation and soil water at 0–10 cm and below 10 cm depths based on data availability. The aim was to determine whether observations from the ECN data support results from the previous hypothesis on dominant run-off mechanism at the study area. Method of analysis involves inferential statistics and wavelet transform plot of selected physico-chemical variables for six (2010–2016) years. Results showed that most of the selected chemical variables exhibited low coefficient of determination in the relationship of their concentration in precipitation and soil water. Relatively linear relationships, however, occurred in the values of conductivity, Cl⁻, Ca²⁺, alkalinity and Mg²⁺ between the 0–10 cm and below 10 cm depths, indicating mixing of soil water at both soil zones. Inference from the results suggests a possible significant role of pre-event water or geological influence on soil water chemistry. The study affirms the hypothesis that saturation overland flow dominates areas underlain by Halstow soil series in the area.

降水与土壤水的化学关系：以英格兰西南部一个集约化管理的草地生态系统为例

环境评估通常需要精细或高分辨率的数据集，例如环境变化网络（ECN）提供的示例。因此，本研究利用了免费访问数据集的优势，以研究降水和土壤水化学的时间特征，以及在0–10 cm深度和10 cm以下的深度中，降水和土壤水中所选化学变量的浓度之间的关系。数据可用性。目的是确定来自ECN数据的观察结果是否支持先前关于研究区主导径流机制的假设。分析方法涉及推断的统计数据和选定的六个物理化学变量的小波变换图（2010-2016年）。结果表明，大多数选定的化学变量在降水量和土壤水中的浓度关系中显示出较低的测定系数。但是，电导率Cl出现相对线性关系⁻，Ca ²⁺，碱度和Mg ²⁺在0-10 cm深度和10 cm以下的深度之间，表明两个土壤区域的土壤水混合。从结果推断出事前水或地质影响对土壤水化学的可能重要作用。该研究证实了以下假设：在该区域内，Halstow土系所覆盖的区域中，饱和的陆上水流占主导地位。
