| 英文摘要 | Land-Use/Land-Cover Change (LUCC) affects farmland productivity by changing the quality of land resource and pattern of land-use. Based on meteorological data and land-use/cover observation dataset obtained from the dynamic serving system of National Resources and Environment Database (NRED), this paper calculated the Photosynthetic Thermal Productivity (PTP) of farmland, and analyzed impact of recent LUCC and climate fluctuation on PTP. Results showed that under the influence of LUCC, PTP distribution had an extensive and unbalanced change. LUCC increased China's total PTP by 26.22 million tons, while climate fluctuation increased it by 169.92 million tons. The ratio between LUCC and climate fluctuation was 1:6.48. Due to the direct effect of LUCC, PTP increased in the following regions: Northeastern Plain, Inner Mongolia, and Xinjiang province. This increase was primarily driven by plantation reclamation. PTP decreased in the Huang-Huai-Hai Plain, the Yangtse Rive delta, the Zhujiang delta, the Southeastern coastal provinces, the southeastern Sichuan basin and the Xinjiang oasis. The decrease was mainly caused by urban expansion. |
