气候变化和人类活动是影响西南岩溶区土壤水分时间变化趋势的两个主要因素，但它们各自对土壤水分变化趋势的贡献仍不确定。基于线性回归趋势分析、Mann-Kendall突变检测和残差分析等方法，定量分析了气候变化和人类活动对西南喀斯特地区土壤水分时空变化趋势的贡献。结果表明：1982 - 2015年，研究区土壤水分经历了一个干化趋势。突变年份为1999年，2000 - 2015年土壤水分下降趋势比1982 - 1999年明显。人类活动和气候变化分别占土壤水分干燥趋势的59%和41%。由于地貌特征的空间异质性，气候变化和人类活动对土壤水分变化趋势的贡献表现出区域差异。实施绿色工程以来，虽然区域植被恢复效果显著，但植被恢复对土壤水分的负面影响不容忽视。本研究定量分析了气候变化和人类活动对土壤水分变化趋势的相对影响，为西南喀斯特地区土壤水资源的可持续利用提供了理论参考。
Climate change and human activities are two dominating factors affecting soil moisture temporal variation trends, whereas their individual contributions to soil moisture trends still remain uncertain in the karst areas of Southwest China. Based on the linear regression trend analysis, Mann–Kendall mutation detection, and residual analysis methods, we quantified the contributions of climate change and human activities to soil moisture temporal variation trends in the karst areas of Southwest China. The results showed that the soil moisture in the study area experienced a drying trend from 1982 to 2015. The mutated year was 1999, and the soil moisture decreasing trend was more evident from 2000 to 2015 than from 1982 to 1999. Human activities and climate change accounted for 59% and 41%, respectively, of soil moisture drying trends. Owing to the spatial heterogeneity of geomorphic features, the individual contributions of climate change and human activities to soil moisture trends exhibited regional differences. Although remarkable regional vegetation restoration was found since applying the Grain for Green Project, the negative impact of vegetation restoration on soil moisture cannot be neglected. This study is a quantitative analysis of the relative impacts of climate change and human activities on soil moisture trends, and our findings provide a theoretical reference for the sustainable use of soil water resources in the karst areas of Southwest China.
