Abstract

As the main driving force for the economic development of East China, the economic development of Anhui has been in good state in recent years. In 2019, the GDP of Anhui Province has reached 3711.4 billion yuan with an increase of 7.5% over the previous year. With the rapid economic development, many environmental problems such as resource depletion, vegetation degradation, and air quality decline have gradually increased. The ecological environment is an important foundation for social and economic development. To examine the status of regional ecological security, this study builds a comprehensive evaluation index system based on the “pressure-state-response” (PSR) framework and uses the entropy weight method to determine the index weight. Then the normal cloud model is introduced to dynamically calculate the ecological security status of Anhui Province from 2010 to 2019. The results show that (1) the ecological security status of Anhui has improved significantly and reached a safe status in 2019. (2) The ecological security status of 16 prefecture-level cities has also been improved, and the ecological security status of these cities is at level III and above except Huainan. There are significant differences in internal development, and the ecological security status of the southern region is ahead of the northern and central region. (3) From the perspective of the criterion level, the pressure and response subsystems develop faster, and the state subsystem develops more slowly. Therefore, it is necessary to pay more attention to the impact of the state subsystem on the overall development of ecological security in the future.
