土壤水分是调节陆地生态系统碳、水、能量循环的重要变量。然而，许多不一致的结论已经报告了关于土壤水分对变暖的反应。在这项研究中，我们进行了一项荟萃分析，以检查土壤水分对包括几种生态系统类型在内的全球变暖地点的实验变暖的反应。结果表明，在大多数生态系统类型中，与对照处理相比，变暖处理使土壤水分下降。森林中土壤水分的减少幅度最大，而草地和农田中的土壤水分减少幅度居中，两者均大于灌木林和苔原生态系统中的土壤水分减少幅度。一些生态系统的土壤湿度也有所增加（或没有变化）。这些结果表明，在大多数生态系统中，土壤干燥的趋势，这可能对各种陆地生态系统过程以及对气候系统的反馈产生了深远的影响。
Soil moisture is an important variable for regulating carbon, water and energy cycles of terrestrial ecosystems. However, numerous inconsistent conclusions have been reported regarding the responses of soil moisture to warming. In this study, we conducted a meta-analysis for examination of the response of soil moisture to experimental warming across global warming sites including several ecosystem types. The results showed that soil moisture decreased in response to warming treatments when compared with control treatments in most ecosystem types. The largest reduction of soil moisture was observed in forests, while intermediate reductions were observed in grassland and cropland, and they were both larger than the reductions observed in shrubland and tundra ecosystems. Increases (or no change) in soil moisture also occurred in some ecosystems. Taken together, these results showed a trend of soil drying in most ecosystems, which may have exerted profound impacts on a variety of terrestrial ecosystem processes as well as feedbacks to the climate system.
