英文摘要	Forests influence climate through both the biochemical and biophysical processes, and the impacts of the latter onlocal climate may be much larger than the former. However, the biophysical effects of afforestation in arid regionshave received little attention compared with afforestation in the tropic, temperate and boreal zones. In this study,we combined in situ eddy covarianceflux measurements from a neighboring pairs of forested and background desertsites with the decomposed temperature metric (DTM) method to characterize the impacts of arid forests on surfacetemperature (Ts). A clear-sky,one-dimensionalplanetary boundary layer (PBL)model was usedto estimatetheimpactsof afforestation on state of regional climate. We showed that despite absorbing more net radiation (35.4 W m-2)theriparian forests tended to coolTs(-1.28 degrees C) on annual basis, but with a significant seasonality. Specifically, afforesta-tion may lead to a net cooling effect from March to September and a slightly warming effect in other months. The DTMmethod revealed that evapotranspiration played a dominant role in cooling surface temperature, while surface albedo (alpha)and incoming longwave radiation (L down arrow) acted together to increase forest surface temperature. From June to September, ashallower, cooler and wetter boundary layer was developed over the forest due to high plant transpiration. In othermonths, the PBL was slightly deeper and warmer over the forest than that over the desert. Therefore, the riparian forestswere important in moderating warming trends in arid regions
