摘要
城市风环境是影响城市污染扩散和人居住环境的一个重要因素。从风环境的角度研究温州城市环境现状;并以温州风环境气象资料为基础,利用城市尺度边界层大气数值模式(RBLM)对三种风速条件下温州城区气流与风速的分布以及污染浓度进行数值模拟。通过分析这三个模拟方案发现鹿城区存在气流辐合区,导致局地污染状况加重;龙湾区污染浓度较大,是造成温州地区污染的主要原因。最后根据试验结果在温州市拟定出排污企业的最佳选址。
The acceleration of urbanization development in the changing social and economic conditions at the same time,also change the urban climate and environment,including urban wind environment affected by a lot.Urban wind environment mainly includes the wind direction and speed,are important factors affect urban atmospheric pollutants transport diffusion.The Angle of wind environment is fromed,study the influence of the urbanization,on the basis of the wind environmental meteorological data in Wenzhou,using the city scale atmospheric boundary layer numerical model（RBLM） simulate air flow and the wind speed distribution and pollution concentration of Wenzhou city about three kinds of wind speed.Analysis the three simulation scheme,airflow convergence zone consist in Lucheng is founded,leading to local pollution is aggravating;Longwan pollution concentration is bigger,is the main cause of pollution in Wenzhou area.Finally,according to the test results,protocol the best location of the pollutant discharging enterprises in Wenzhou city.
