Ecosystem resilience comprehensively reflects the cushioning and self-regulating ability of ecosystems. Studying the spatio-temporal evolution characteristics of China's ecosystem resilience is of great significance for China's ecosystem health assessment and policy of ecosystem protection. Nevertheless, in previous studies, there have been a few studies on the spatio-temporal evolution characteristics of the ecosystem resilience at the county level in China. Based on the ecosystem resilience assessment structure, this study had been measuring the spatio-temporal evolution of China's ecosystem resilience from 2000 to 2015 based on long-term sequence land use/cover change, vegetation coverage index, and climate data. The study results show that:(1)In 2000, 2005, 2010 and 2015, China's ecosystem resilience was 0.208, 0.201, 0.185 and 0.188, respectively. China's ecosystem resilience has generally declined from 2000 to 2010, and the self-regulation of ecosystems have been weakened, but improved slightly in 2015;(2)The high-level counties of ecosystem resilience during the study period are mainly distributed in Sichuan, Yunnan, Guizhou and Chongqing in the southwest of China, other counties including Taihang Mountain, Wushan, Xuefeng Mountain, Nanling and Wuyishan are also high-level counties of ecosystem resilience; and low-level counties of ecosystem resilience are mainly distributed in the northwest of China. The results of this study have vital implications for the policy of land use making and spatial planning of national land.
