Abstract EN
Climate change inevitably leads to changes in hydrothermal circulation.
However, thermal-hydrologic exchanging caused by land cover change has also undergone ineligible changes.
Therefore, studying the comprehensive effects of climate and land cover changes on land surface water and heat exchanges enables us to well understand the formation mechanism of regional climate and predict climate change with fewer uncertainties.
This study investigated the land surface thermal-hydrologic exchange across southern China for the next 40 years using a land surface model (ecosystem-atmosphere simulation scheme (EASS)).
Our findings are summarized as follows.
(i) Spatiotemporal variation patterns of sensible heat flux (H) and evapotranspiration (ET) under the land cover scenarios (A2a or B2a) and climate change scenario (A1B) are unanimous.
(ii) Both H and ET take on a single peak pattern, and the peak occurs in June or July.
(iii) Based on the regional interannual variability analysis, H displays a downward trend (10%) and ET presents an increasing trend (15%).
(iv) The annual average H and ET would, respectively, increase and decrease by about 10% when woodland converts to the cultivated land.
Through this study, we recognize that land surface water and heat exchanges are affected greatly by the future climate change as well as land cover change.
