| 英文摘要 | Photosynthetic capacity is often quantified by the Rubisco-limited photosynthetic capacity (i.e. maximum carboxylation rate, V-cmax). It is a key plant functional trait that is widely used in Earth System Models for simulation of the global carbon and water cycles. Measuring V-cmax is time-consuming and laborious; therefore, the spatiotemporal distribution of V-cmax is still poorly understood due to limited measurements of V-cmax. In this study, we used a data assimilation approach to map the spatial variation of V-cmax for global terrestrial ecosystems from a 11-year-long satellite-observed solar-induced chlorophyll fluorescence (SIF) record. In this SIF-derived V-cmax map, the mean V-cmax value for each plant function type (PFT) is found to be comparable to a widely used N-derived V-cmax dataset by Kattge et al. (2009). The gradient of V-cmax along PFTs is clearly revealed even without land cover information as an input. Large seasonal and spatial variations of V-cmax are found within each PFT, especially for diverse crop rotation systems. The distribution of major crop belts, characterized with high V-cmax values, is highlighted in this V-cmax map. Legume plants are characterized with high V-cmax values. This V-cmax map also clearly illustrates the emerging soybean revolution in South America where V-cmax is the highest among the world. The gradient of V-cmax in Amazon is found to follow the transition of soil types with different soil N and P contents. This study suggests that satellite-observed SIF is powerful in deriving the important plant functional trait, i.e. V-cmax, for global climate change studies. |
