| 摘 要： | 本文利用三维土壤－植被－大气耦合的区域气候模式模拟分析植被覆盖状地山谷风环流形成与演变过程的影响。结果表明，植被覆盖状况不仅影响风速大小和环流强弱经，而且对环流的形成和维持也有很大影响。植被覆盖度越大，山谷风环流形成时间越滞后，风速越小，环流强度越弱，维持时间越短。

| Abstract: | In this paper, the effects of vegetation cover condition on formation and evolution of mountain-valley wind are studied by utilizing three-dimensional soil - vegetafion- atmosphere coupled regional climate model. The results show that vegetation cover condition not only have effects on wind velocity and circulation strength, but also on formation and persistence of mountain-valley circulation. The larger the vegetation cover, the later the formation, the less the wind velocity, the weaker the circulation strength, and the shorter the persistence time of the mountain-valley wind circulation. |
