Spatiotemporal evolution of the resilience of the coastal complex ecosystem in the East China Sea from 2001 to 2020
The coastal zone is a region characterized by frequent natural,social,and economic interactions.However,excessive and intensive development poses a significant threat to the ecological environment of this area.Understanding the resilience of these ecosystems is crucial for effective ecological protection.Therefore,this study aims to comprehensively evaluate the spatiotemporal evolution of the resilience of the coastal zone complex ecosystem in the East China Sea region.By integrating multiple data sources,we construct an evaluation system that considers the baseline state of the complex ecosystem,the coupling and coordination relationship between social and economic development,resource and environmental endowment,the sustainable development potential of the complex ecosystem,and the range and intensity of human activities'impact on the environment.We quantitatively evaluate the resilience of the coastal zone complex ecosystem from 2001 to 2020 and analyze the influencing factors of its spatiotemporal evolution characteristics and spatial differentiation.The results indicate that:(1)From 2001 to 2020,the resilience of the complex coastal ecosystem in the East China Sea showed a fluctuating downward trend,with significant spatial heterogeneity and a noticeable coastal-land gradient.(2)Forests play a crucial role in maintaining the resilience of the regional complex ecosystem.(3)Factors reflecting the distribution and intensity of human activities have an increasing impact on the resilience of the complex ecosystem.This research provides theoretical support and practical references for the protection,restoration,and sustainable utilization and management of coastal zone complex ecosystems.
