摘　　要：高密度城市和建筑群可对气候产生重要影响,例如热岛效应、空气污染和暴雨等。科学准确地评估城市对气候的影响并据此提出规划改善对策已成为建设生态城市和宜居环境必不可少的重要内容。本文对可用于城市气候评估的模型进行了归纳总结,发现以CFD耦合模型和WRF为代表的中尺度气象模型具有优势,前者更适合建筑、城市设计和详规尺度;后者更适合城市总规尺度;利用GIS平台将气候评估结果与城市信息数据库进行叠加分析或者绘制城市气候图可以更好地对接规划实践需求。Buildings in high density cities hinder wind and cause urban heat island effect, ai r pollution and rai nstor m. Scientif ically and accu rately evaluati ng the i nf luence of cities on wind and proposing improvement counter measures have been a necessar y par t of building the ecological cities and livable environment. The ar ticle summarizes wind evaluation models, finding that CFD and WRF coupling models have advantages, and the for mer is more suitable for urban design and detailed planning scale, the latter is more suitable for master planning scale; and that integrating wind evaluation results with urban infor mation databases by GIS platfor m can provide better guideline for urban planning practice.
