Spatial distribution characteristics of natural ecological resilience in China.

High-intensity exploitation of land resources and the natural environment can upset the balance of ecosystems, causing multiple ecological problems and affecting regional sustainable development. Recently, China has carried out integrated regional ecosystem protection and restoration governance. Ecological resilience (ER) is the foundation of and key to achieving sustainable regional development. Based on the significance of ER in ecological protection and restoration efforts and the necessity of conducting large-scale studies, we conducted relevant research on the ER in China. In this study, we selected typical impact factors to construct an assessment model of ER in China and quantitatively measured its large-scale spatial and temporal distribution characteristics, while also exploring the relationship between ER and land-use types. The country was zoned according to the ER contributions of each land-use type, and ER enhancement and ecological protection were discussed based on the characteristics of different regions. The ER in China shows clear spatial heterogeneity and spatial agglomeration, roughly represented by high and low ER in the southeast and northwest regions. The mean ER values of woodland, arable land, and construction land were all greater than 0.6, with more than 97% of the ER values at levels of medium or above. The country can be divided into three regions based on the degree of ER contributions of various land-use types, each with different ecological problems. This study provides a detailed understanding of and explores the important role of ER on the regional development process, and provides support and reference for regional ecological protection and restoration as well as sustainable development.
