An virtual numerical experiment to understand the impacts of recovering natural vegetation on the summer climate and environmental conditions in EastAsia

By applying a regional integrated environmental model system (RIEMS), a vir tual numerical experiment is implemented to study the impacts of recovering natural vegetation on the regional climate and environmental conditions. T he results show that recovering the natural vegetation in large scale could have significant influence on summer climate in East Asia. Not only would it be able to change the surface climate, but also to modify to certain ext ent the intensity of monsoon circulation. Although this is a virtual experi ment at an extremely ideal condition, the implication of the simulating res ults is that the on-going nation-wide activities to recover the crop land f or forest and pasture must be managed according to the local natural climat e, hydrological and soil conditions. Only under such a condition, would the recovering of natural vegetation bring about significant climate and envir onmental benefits at regional scale.
