Abstract:

Ecological protection and restoration has become a core content for the construction of ecological civilization in China. The study of ecological vulnerability is an important basis for evaluating ecological environmental problems, and for performing ecological protection and restoration. To scientifically identify the formation mechanism and ecosystem vulnerability variation in the ecological restoration area of mountains-rivers-forests-farmlands-lakes-grasslands in Tai’an City, and to clarify the direction of ecological protection and restoration, we used the pressure state response (PSR) framework model to evaluate the local ecological vulnerability. We further diagnosed the ecological environment problems in combination with the evaluation results, thus put forward countermeasures for ecological protection and restoration. The results show that the low vulnerability areas account for the highest proportion (37.97%), indicating that the overall local ecosystem is relatively stable. Among the investigated counties, cities and districts, there is higher proportion of vulnerability areas in the Taishan (48.77%) and Daiyue (37.15%) districts and Feicheng (30.97%) city, indicating that the ecosystem of the three counties is unstable. Considering the local situation, we put forward five ecological restoration suggestions, including (1) promote mine ecological restoration, (2) improve forest and grass coverage, (3) comprehensively regulate the watershed system, (4) increase biodiversity and improve ecological security system. The evaluation results and the proposed ecological restoration countermeasures are helpful to the rational layout of the project. It can also facilitate the targeted planning of the construction of ecological civilization in the implementation of the local ecological protection and restoration project of mountains-rivers-forests-farmlands-lakes-grasslands, and provide reference for the implementation of the ecological restoration project of mountains-rivers-forests-farmlands-lakes-grasslands in China.
