It is a key issue for regional high-quality development to explore that the spatial-temporal correlation mechanism between ecological pressure and landscape ecological risk in coastal areas.Based on the Zhejiang coastal zone,we evaluated the relationship between the Ecological Pressure Index(EPI)and the Ecological Risk Index(ERI)by using Bi-variate Spatial Auto-correlation model and Coupling Coordination Degree Model,and constructed a structural equation model to analyze the coupling mechanism.The results showed:(1)the temporal characteristics of EPI in Zhejiang coastal zone fluctuated and increased from 2000 to 2020.The spatial pattern of EPI was higher in the north and lower in the south,forming a triple core spatial pattern,such as the coasts of Hangzhou,Ningbo,and Wenzhou.(2)The levels of ERI have deepened from 2000 to 2020.The ERI exhibited a distribution pattern characterized by higher levels in the central and southern coastal zones and lower levels in the northeastern zones.(3)There is a local spatial autocorrelation relationship between EPI and ERI in Zhejiang coastal areas.Specifically,the areas of Taizhou Bay,Yueqing Bay,and Wenzhou Bay have Low-High agglomeration,poor coupling and coordination,and ERI lags behind EPI.By contrast,the Hangzhou Bay area is highly concentrated with good coupling and coordination,and the development of EPI and ERI tends to be synchronized.(4)The ecological pressure of Zhejiang coastal zone has a significant positive correlation with landscape ecological risk.Based on the types of bay,we provided the classification guidance to achieve effective governance of the coastal zone.
