- 为探索创新科技城对局地气候舒适性的影响,利用WRF数值模式,对成都市双流区待建创新科技城的位置与面积规划进行敏感性试验。结合当地主导风向和实际项目需求,设计了不建设创新科技城、创新科技城占地面积9 km2、12 km2和16 km2 4种面积敏感性试验,以及创新科技城位于双流地区中部、北部、南部、西部和东部5个方位的位置敏感性试验。通过对比下垫面修改前后模拟结果的2米气温、2米湿度、10米风速等气象要素以及两米人体舒适度指数,认为创新科技城建设面积约12 km2,且位于双流地区中部最合适。
- Abstract:
- WRF value pattern is adopted for sensitively testing the position and area of innovative and scientific city which under construct in Shuangliu,Chengdu for the sake of exploring the impact that Innovative and scientific city on local climate comfort.Considering the local dominant wind direction and the practical project demand, four area sensitivity tests are designed which including not to build innovative science city,constructing innovative science city which covers an area of 9,12 and 16 kilometers square.Five position sensitivity experiments are designed which including innovative science city is located in the central, northern, southern,western and eastern parts of Shuangliu area.By comparing meteorological factors such as the temperature and humidity of 2 meters high,wind speed of 10 meters high of simulated results when underlying surface is modified before and after. we suggest that the Innavative scienceCity has the most suitable setting when the constructed area is approximately 12 square kilometers and the location is in the middle of Shuangliu.
