The Study on Ecological Security Evaluation of the Minghu National Wetland Park

Comprehensively analyzing Liupanshui Minghu National Wetland Park ecological safety impact factors including environment, resources, ecology, economy, and society, utilizing the Driver force-Pressure-State-Impact-Response-Management (DPSIRM) framework model to build Minghu National Wetland Park ecological security DPSIRM evaluation index system and employing the mean square error (MSE) method to establish the weight value of evaluation index, using the set pair analysis method to set up evaluation model, this paper evaluates the wetland ecological security in Minghu National Wetland Park from 2017 to 2022. The results show that the natural population growth rate, domestic sewage discharge, per capita water resources, species diversity, sewage treatment rate, and environmental protection investment index are the main influencing factors of the ecological security of Minghu National Wetland Park. The ecological security of Minghu National Wetland Park is gradually improving. From 2017 to 2018, the result of h4 was 0.7576 and 0.7876, respectively. This means that ecological security belongs to the unsafe level. From 2019 to 2022, the result of h3 was 0.5176, 0.5680, 0.6767, and 0.7281, respectively. Its ecological security belongs to the critical safety level. From the perspective of various evaluation factors, the driving force and influencing factors belong to the relatively safe level, while the pressure, state, and management factors belong to the critical safety level, and the response factors belong to the unsafe level. The response factor is the important influencing factor of the ecological security of Minghu National Wetland Park. Through research, scientific references have been provided for the ecological security construction of Minghu National Wetland Park.
