空气资源管理的概念起源于美国,随后成为发达国家大多数空气质量控制计划的基础。然而,其在区域大气环境管理中的有效性和定量评价方法却鲜为人知。本研究的目的是构建空气资源禀赋指数,并将其应用于评估2013年至2017年中国在大陆的空气资源禀赋分布情况。ARE指数的量化包括大气扩散系数(A值)和自净能力(B值)两个项,可通过天气研究和预报模式(WRF-CALMET)计算。结果表明,中国约15%的土地面积ARE较高,约20%-25%的中国土地面积被认为是相对较高或相对较低的土地面积,而中国的其余土地面积(40%)被认为是低ARE。在此基础上,基于ARE指数的数据挖掘,建立了复杂网络关联模型,并用于划分高度相关的区域。确定了ARE指数具有较强同步性的6个关键大气污染联合防治(JPCAP)区域,这表明JPCAP可以在每个划定的区域内单独实施。本研究提出的确定区域和区域划分的概念和分析方法,对中国实施JPCAP具有广泛的指导意义。
The concept of air resource management originated in the United States and subsequently became the foundation of most air quality control programs in developed countries. However, little is known about its validity and quantitative assessment methods in regional atmospheric environment management. The aim of this study was to construct an air resource endowment (ARE) index and apply it in a case study for assessing the distribution ofAREacross mainland China from 2013 to 2017. The quantification of theAREindex includes two terms: the atmospheric diffusion coefficient (Avalue) and self-purification ability (Bvalue), which can be calculated via Weather Research and Forecasting modeling (WRF-CALMET). The results indicated that about 15% of China's land area enjoys highARE, around 20–25% of China's land area was considered to have relatively high or relatively lowAREindices, andAREin the rest of China's land area (40%) was considered to be low. Further, a complex network correlation model was created and used to demarcate highly inter-correlated regions based on the data mining of theAREindex. Six key Joint Prevention and Control of Atmospheric Pollution (JPCAP) regions with strong synchronicity in theAREindex were identified, which suggests that JPCAP could be implemented separately within each of these demarcated regions. The concepts and analysis methods proposed in this study for determiningAREand regional divisions can have broad significance for JPCAP implementation in China.
