锡林郭勒盟煤电基地大气环境容量分析及预测

Analysis and prediction of the atmospheric environmental capacity of the Xilinguole League's coal-based electricity region

内蒙古锡林郭勒盟国家大型煤电基地既是我国经济发展和区域能源安全的重要基地,又是近首都生态重要屏障保障区域,该区域的生态环境建设直接关系到国家生态安全。选取锡林郭勒盟煤电基地为研究对象,以研究区内各大气污染物排放数据为基础,对照大气环境功能区划,研究大气环境容量。首先绘制了各主要污染物的区域空间分布图,结合功能区大气质量标准得到了锡林郭勒盟环境容量和承载力的空间分布结果。在此研究基础上,按不同目标情景(低标准、中等标准、高标准)进行了区域大气环境承载力的预测,分析了各区域的环境保护对策。为锡盟国家煤电基地建设和生态保护及区域可持续发展提供科学依据。

Abstract： Coal-based electricity of the Xilinguole League area in Inner Mongolia is not only an important foundation for the country＇s economic development and energy security, but also an ecological protective screen nearby the capital. And the construction of coal-based energy infrastructure in this region directly affects its ecological security. In this study, the atmospheric pollutant emissions from coal-fired power plants Xilinguole League and its air quality were investigated, and the spatial distribution of the atmospheric environmental capacity was analyzed. The spatial distribution of major pollutants was mapped and combined with atmospheric quality standards to obtain the atmospheric environmental capacity. Based on these results for different scenarios （low, medium, or high standards） , the predicted regional atmospheric environmental capacity was calculated, and the regional environmental protection countermeasures were analyzed. These results provide a scientific basis for the conservation and regional sustainable development of Xilinguole League.
