中文摘要：

为了进一步研究福建土楼优秀的生态特性,深入研究其室内热环境,土楼民居内部的风环境模拟测试是必不可少的前提步骤.依据福建圆形土楼民居的当地夏热冬暖地区气候环境,提取其典型建筑类型的空间原型,利用PHOENICE分析软件,对在封闭和开敞两种状态下圆形土楼民居内部院落的风环境状况进行了模拟,分析内院空间的通风性能.结果表明：封闭状态下的内院风环境较为稳定,开敞状态下的内院空间通风状况良好,为营造良好的室内热环境提供了适宜条件;福建土楼民居应合理利用自然通风的各种技术措施,适当加入导风板、兜风结构设计等改造设计,实现传统民居的可持续发展.

英文摘要：

To further study the ecological characteristics of the Earth Houses in Fujian with an in-depth study on the indoor thermal environment,the wind environment simulation testing is an essential prerequisite step.Depending on the local climate of the subtropical region,and extracting of the prototype space for a typical building type using analysis software—PHOENICE,Earthen residential buildings,both in closed and open states a circular,were simulated wind environment,analysis of the ventilation performance space in Internal courtyard.It is conclusded that closed state of the wind environment is more stable than the open states and it is a good optimal condition to create a good indoor thermal environment.Fujian Earthen Houses should be rational use of natural ventilation technical measures,To achieve the sustainable development of traditional houses,we can add appropriate air deflector,a drive transformation of the design structure design.
