Answer]: BNote that the question is about the "Ambient Air Quality Standard" (GB3095-2012); One of the differences between the old and new standards of the "Ambient Air Quality Standards" is that the new standards distinguish the ambient air functions into two categories:

The first category of areas is nature reserves, scenic spots and other areas that need special protection; The second type of area is residential area, commercial and traffic mixed residential area, cultural area, industrial area and rural area. The old standard distinguishes the ambient air quality function into three categories: the first section is a nature reserve, a scenic spot and other sensitive areas that need special protection; The second-class areas are residential areas, mixed commercial and transportation residential areas, cultural and residential areas, general industrial areas and rural areas determined in the town planning; The three types of zones are specific industrial zones.
