Measurement and Evaluation of Ecological Protection Level in the Yellow River Basin
Strengthening the ecological protection level of the Yellow River Basin is the only way to promote the high-quality development of the Yellow River Basin and realize the harmonious coexistence between man and nature.Based on the data of nine provinces and regions in the Yellow River Basin from 2006 to 2020,a comprehensive evaluation index system of ecological protection level in the Yellow River Basin was constructed from three dimensions,such as ecological status,ecological pressure and ecological response,and the entropy method was used to calculate the ecological protection level.The results show that the ecological protection level of the basin is on the rise from 2006 to 2020,but the difference is obvious among provinces.The ecological protection level in the upper reaches is obviously higher than that in the middle and lower reaches,Qinghai and Sichuan are in the leading position,and Ningxia has the lowest ecological protection level.Finally,some suggestions are put forward to improve the level of ecological protection,including to strengthen the ecological protection in the downstream area,strengthen the ecological management and restoration,and improve the efficiency of resource utilization.
