Paper title：Under the Coupled Regulation of Ecological Vulnerability and Economic Development: PM2.5 Pollution Characteristics and Health-Economic Responses in the Qinghai Plateau Paper abstract：Air pollution (especially PM2.5) severely threatens global health and the economy, with impacts tied to regional social development and geography. As an ecologically fragile plateau region, Qinghai faces complex PM2.5 pollution due to unique geographical conditions and economic development, while existing studies lack province-wide, health-oriented, economy-indexed quantitative assessments of source-specific pollution. This study coupled receptor, atmospheric numerical, machine learning, and health-economic loss models to clarify Qinghai’s PM2.5 characteristics and health-economic responses. Dust (soil and industrial dust) was identified as the primary PM2.5 contributor and sole province-wide driver of health-economic losses. Regulated by the ‘Qaidam Transport Channel’, dust forms a ‘west emission-east accumulation’ pattern, with regional population density and economic level amplifying its health burden. Scenario projections show controlling PM2.5 to 10-12 μg/m3 by 2035 yields economic benefits. The study clarifies that fragile ecology-dust intrusion-economic development superimposition, topographic-driven diffusion differences, and high population exposure collectively increase health burdens. Thus, prioritizing ecological protection for PM2.5 source reduction (based on green economy) is critical to safeguarding residents’ health in this fragile region.
