WRF-CMAQ模型在工业园区规划环评的应用

Application of WRF-CMAQ model in planning environmental impact assessment of industrial park

随着我国社会工业的逐渐发展,工业园区建设需求日益涌现。大气环境影响评价是工业园区规划环评的重要内容之一。在具体的环评中,要结合实际情况,科学选择评价方法,保障大气环境影响评价的有效性。随着中尺度大气模式的不断发展,新一代中尺度天气研究和预报模式WRF因其完全开放、可移植性强、更新快等特点在国内外得到了广泛应用。WRF-CMAQ模型对大气污染物及PM2.5主要化学组分的模拟效果较好,可以反映PM2.5及其组分的时空变化特征。采用WRF-CMAQ模型,对某工业园区规划环评的大气开展了预测工作,并根据预测结果提出了园区优化改进措施。

With the gradual development of social industry in China,the demand for industrial park construction is emerging day by day.The atmospheric environmental impact assessment is one of the important contents in the EIA of industrial park planning.In the specific environmental impact assessment,the assessment method should be scientifically selected to ensure the effectiveness of the environmental impact assessment.With the development of mesoscale atmospheric model,the new generation of mesoscale weather research and Forecast Model WRF has been widely used at home and abroad because of its open,transplantable and quick update.The WRF-CMAQ model can simulate the air pollutant and the main chemical components of PM2.5,and can reflect the temporal and spatial variation characteristics of PM2.5 and its components.The atmosphere of a planned environmental impact assessment of an industrial park was predicted by using the WRF-CMAQ model,and the improvement measures were put forward according to the predicted results.
