摘要
本文利用三维土壤－植被－大气耦合的区域气候模式研究了干旱半干旱地区植被状况发生变化的短期气候效应，着重分析植被对海平面气压场、近地层气温和湿度、土壤温度、边界层风速、局地环流以及地面能量平衡和转换关系的影响，结果可为人们制定合理的农业种植制度，开发和利用有限的生物资源，推广植树种草绿化工程建设，改善区域气候环境提供一定的科学依据。
A three - dimensional soil - vegetation - atmosphere coupled regional climate model is used in this paper to strudy the effects of vegetation condition changes on regional shortterm climate in arid or semi -arid area, with stress laid on analyzing the effects of vegetation on sea level pressure, air temperature near surface and soil temperature, wind speed in planetary boundary layer, ciculation, surface energy balance and transition et al. The results obtained can provide climatic bases for developing and utilizing limited plant resources and for improving regional climate environment.
