Abstract

Abstract: Based on the Pressure-State-Response (PSR) model, an ecological security evaluation system was constructed to evaluate the evolution trend of ecological security in Zhejiang Province from 2013 to 2022. The results indicated that the comprehensive index of ecological security in Zhejiang Province exhibited an upward trend, from the extremely unsafe state in 2013 to the relatively safe state in 2022, and the ecosystem of the whole province was in a relatively stable state. The three indexes of resource and environmental pressure, ecosystem status and human response all showed positive contributions to the ecological security pattern of Zhejiang Province. The improvement of some indicators was close to the bottleneck, and the follow-up improvement of ecological security status was facing considerable pressure. Based on the evaluation results, some countermeasures and suggestions were put forward, so as to provide decision-making reference for rapid and appropriate response to various risks and challenges and comprehensive maintenance of ecological security in Zhejiang Province.

Key words: ecological security, Pressure-State-Response (PSR) model, analytic hierarchy process, Zhejiang Province
