武汉市黄陂区古树名木资源特征调查与保护建议

为了摸清武汉市黄陂区内古树名木的资源特征情况，采用资料查询、知情人走访、现场考察的方法，对黄陂区内古树名木的种类、数量、胸径、树龄、海拔分布等22项特征因子进行调查。结果表明：黄陂区总计拥有古树名木867株，包括26科36属40种，古树群落3处，其中：Ⅰ级古树30株，Ⅱ级古树71株，Ⅲ级古树766株；朴树最多，为269株，其次为枫香树150株，柿139株。古树名木资源的分布主要集中在木兰乡、王家河街、六指街、蔡家榨街、蔡店街、姚集街，不同区域的生长情况差别明显，祁家湾街、罗汉寺街的古树生长环境较差，不同树种海拔分布差异较大。

室外装饰材料在靖港古镇景观恢复中的价值评价分析

古镇的开发使其历史文化景观遭到了严重的破坏,其中对室外装饰材料的影响尤为明显。以靖港古镇为研究对象,采用问卷调查和灰色关联分析法,从定性与定量的角度分析评价了室外装饰材料特性及影响因素在靖港古镇景观恢复中的价值高低和整体表现。根据得分高低判断出各种材料在靖港古镇景观恢复价值中的优劣,得分前五名的材料是木材、石材、砖、瓦和植物,较低得分的是混凝土、油漆、金属、玻璃和塑料。     

Wind Tunnel Test and Numerical Simulation of Wind Induced Loads on Complex Shaped High Rise Buildings

Taking a complex shaped high rise building as a case, the wind tunnel test with rigid model was carried out for wind load study. Meanwhile, with Fluent 6.1 software, the CFD numerical simulation had been performed with the RSM and the Non equilibrium Wall Functions. It was found that the results of the two methods were in good agreement. There were mainly positive pressures on the windward surface and negative pressures on the roof, the leeward surface and the side. Especially, negative pressure was higher in the leeward region at the building corner. And at the wind angle of 180°, the wind speed amplification effect was remarkable which was similar to those of canyons.
