| 英文简介 | Evapotranspiration (ET) is a central process in the climate system and a nexus of the hydrologic, energy cycles. The actual evapotranspiration (ETa) response to global climate warming is a hot and difficult issue of climate change and hydrologic circulation field. According to the lack of the comparative research from different theory and in different watersheds/regions, this project will use the water balance model in region/basin and station scales to compare the Penman proportional hypothesis theory, Bouchet complementary relationship theory and Budyko water heat coupling theory, and determine the inherent relationship between the ETa and the potential evapotranspiration (ETp) in the main regions/basins of China. Based on the final selected model, the project will calculate and analyze the Spatio-temporal variation of the ETa of China under the Global Warming. The project will analyze the influence of the climate factors on the ETa and the sensitivity of the ETa to the change of the main impact factors. Finally, the project will give the cumulative contribution on the ETa from such changes. It will provide some useful supplement to the China climate change and hydrologic cycle reserch. |
