Abstract:
Objective Based on the Pressure-State-Response (PSR) model and Environmental health indicators (EHIs), the comprehensive environmental health risk index of the Yangtze River economic belt is assessed to evaluate the comprehensive environmental health risk of the study area from 2016 to 2020. Methods Reference to the results of the Second National Pollution Source Census, a comprehensive environmental health risk assessment system was established. Twenty three representative indicators covering the four directions of economy, society, environment and health were selected. The above indicators were standardized using the range method, and each indicator was weighted using the entropy weight method. Results From 2016 to 2020, the comprehensive risk of environmental health in the Yangtze River Economic Belt showed a downward trend. The comprehensive health risk index decreased from 0.5450 to 0.3255, and the risk level has changed from "medium risk" to "low risk". Conclusion The overall environmental health of the Yangtze River Economic Belt has been improving, but it is still necessary to note that with the economic development, the regional pressure risk index has been rising rapidly, and corresponding measures should be taken to maintain the balanced development of economic and environmental health.
