| 英文摘要 | Highlights What are the main findings? A significant global shift occurred around the year 2000: The rate of vegetation greening accelerated significantly after this point, coinciding with a reversal in soil moisture trends from general drying (1982-1999) to wetting (2000-2020). Notably, this post-2000 wetting trend was most pronounced in temperate and tropical climate zones compared to cold and arid regions. The drivers of soil moisture are complex, and vegetation's regulatory role is growing: The primary factors controlling soil moisture vary by season, climate zone, and soil depth. For instance, for rootzone soil moisture, vegetation (LAI) is dominant in winter and spring, while solar radiation becomes the primary driver in summer and autumn. Crucially, the overall influence of vegetation (LAI) on soil moisture has significantly strengthened over time, generally contributing to a wetting trend. Although vegetation is not the absolute dominant factor in all seasons, the growth of its influence is particularly pronounced in specific periods: for rootzone soil moisture, its influence increased the most during winter and summer, while for surface soil moisture, the increase was most significant in winter. This highlights the increasingly important regulatory role of vegetation in the global water cycle. What are the implications of the main findings? Improved prediction models are needed for water resource management: The finding that vegetation's role in regulating soil moisture is growing stronger means that traditional climate-only models may be insufficient. These results provide a scientific basis for improving global models by better incorporating the dynamic effects of vegetation greening, leading to more accurate predictions of soil moisture and better management of water resource risks under climate change. A deeper understanding of Earth's ecohydrological processes: This research clarifies the complex, intertwined relationship between the climate, plants (biosphere), and water (hydrosphere). Understanding that factors like the timing of peak vegetation growth (POS) can directly influence soil moisture provides a more nuanced view of terrestrial ecosystems, which is fundamental for assessing ecological responses to global environmental changes.Highlights What are the main findings?

However, the seasonal and climate zonal variations in soil moisture dynamics at different depths, driven by both climate and vegetation, remain insufficiently explored. This study provides a comprehensive analysis of the global patterns in rootzone and surface soil moisture and leaf area index (LAI) across different seasons and climate zones, utilizing satellite observations from 1982 to 2020. We investigate how climatic factors and LAI influence soil moisture variations and quantify their dominant contributions. Furthermore, by employing key vegetation phenological indicators, namely the peak of growing season (POS) and the corresponding maximum LAI (LAIMAX), we assess the feedback effects of vegetation phenology on soil moisture dynamics. The results indicate that the greening trend (as reflected by LAI increases) from 2000 to 2020 was significantly stronger than that observed during 1982-1999 across all seasons and climate zones. Both rootzone and surface soil moisture shifted from a decreasing (drying) trend (1982-1999) to an increasing (wetting) trend (2000-2020). From 1982 to 2020, the LAI induced moistening trends in both surface and rootzone soil moisture. In arid and temperate zones, precipitation drove rootzone soil moisture increases only during the summer. Among all seasons and climate zones, solar radiation induced the strongest surface soil drying in tropical summers, with a rate of -0.04 x 10-3 m3m-3/Wm-2. For rootzone soil moisture, LAI dominated over individual climatic factors in winter and spring globally. In contrast, solar radiation became the primary driver during summer and autumn, followed by precipitation. For surface soil moisture, precipitation exhibited the strongest control in winter, but solar radiation surpassed it as the dominant factor from spring through autumn. In the tropical autumn, the sensitivity of rootzone and surface soil moisture to POS (and LAIMAX) was highest, at 0.059 m3m-3d-1 (0.256 m3m-3/m2m-2) and 0.052 m3m-3d-1 (0.232 m3m-3/m2m-2), respectively. This research deepens the understanding of how climate and vegetation regulate soil moisture across different climate zones and seasons. It also provides a scientific basis for improving global soil moisture prediction models and managing water resource risks in the context of climate change. |
