英文摘要	The Carbonate rock weathering Carbon Sink (CCS) and Silicate rock weathering Carbon Sink (SCS) play a significant role in the carbon cycle and global climate change. However, the spatial-temporal patterns and trends of the CCS and SCS from 1950 to 2099 have not been systematically quantified. Thus, Supported by long-term hydrometeorological data under the RCP8.5, we use the accepted Suchet and Hartmann models to determine the following. First, we found except for the difference in their weathering rates, the SCS covers 37.2 million km(2) more area than the CCS. The CCS Flux (CCSF) and SCS Flux (SCSF) are 5.36 and 1.22 t/km(2)/yr, respectively. Similarly, the Full CCS (FCCS, 0.3 Pg/yr) is more than the Full SCS (FSCS, 0.08 Pg/yr). Furthermore, the CCS (7.01 kg/km(2)) and SCS (3.95 kg/km(2)) are in a state of overall increase. In addition, the mid-to-high latitudes of the northern hemisphere are aggravated by warming (0.03 degrees C) and humidity (0.65 mm), while the decrease in runoff in the mid-latitudes of the southern hemisphere reduces karstification. Specifically, by 2099, the CCSF in the mid-latitudes of the southern hemisphere will decrease by 5.72%. Instead, the CCSF in the northern hemisphere and lower latitudes of the southern hemisphere will exhibit a gentle upward slope. Particularly, the peak regions of the global FCCS (65.63 Tg/yr) and FSCS (33.01 Tg/yr) are the tropical zone. In conclusion, this study contributes a high-resolution and long-time series CS datasets for the CCS and SCS. We provide data and a theory for solving terrestrial carbon sink loss.
