城市大气环境分区管控方法与实践:以保山市为例

Method and Practice of City Atmospheric EnvironmentalSubarea Control:a Case of Baoshan City

采用NCEP再分析资料和地面气象观测数据,利用中尺度天气数值模式WRF和空气质量模式CALPUFF对保山市大气环境布局敏感性和扩散性能进行评价,开展管控分区划定,提出分区管控策略,探讨其在不同领域的应用思路。结果表明:模式能够有效模拟识别出大气环境布局敏感区和弱扩散区,布局敏感区主要分布在各县城的上风向、输送通道等区域,弱扩散区主要分布在保山市南部的山谷河谷地区;将大气环境管控分区划分为优先保护区、重点管控区和一般管控区三级,各分区需根据自身属性特征实施差异化的大气环境管控策略;大气环境分区管控的实施和应用有利于推动产业转型升级,促进环境空气质量改善,形成国土空间保护和开发相协调的空间格局。

Based on the NCEP reanalysis data and the ground weather observation data,the WRF and CALPUFF models were used to evaluate the atmospheric environmental layout sensitivity and diffusion performance of BaoshanCity.The result helped to demarcate control zones,put forward subarea control strategy,and discuss its application in different fields.It showed that the layout sensitive area and weak diffusion area of atmospheric environment could be simulated and identified effectively by the models.The layout sensitive areas were mainly distributed in the upwind and transportation channels of each county.The weak diffusion areas were mainly distributed in the valley in the south of Baoshan.The air environmental control zones were divided into priority protection zones,key control zones and general control zones,and each zone should implement differentiated management strategies according to its own attributes and characteristics.The implementation and application of atmospheric environmental subarea control were conducive to promoting industrial transformation and upgrading,improving ambient air quality,and forming a spatial pattern in which the protection and development of national space are coordinated.
