ABSTRACT In response to the risks posed by urbanization and climate change land availability, China has implemented several significant cover restoration initiatives since 1998. These have notably contributed objectives of 27th Conference Parties United Nations Framework Convention on Climate Change (COP27). However, a systematic evaluation ecological effects vegetation from these been lacking. This study utilized NDVI, NPP, TerraClimate data comprehensively assess spatial temporal variations in Vegetation Ecological Quality Index (VEQI) across analyze its initiatives. The analysis, spanning 2002 2022, various remote sensing sources geostatistical techniques, including Hurst index, multiple regression residual meta‐scale Theil–Sen median trend analysis. results indicate consistent increase China's VEQI over past 20 years. Notably, Natural Forest Resources Protection Project Beijing–Tianjin Wind Sand Source Comprehensive Control played crucial roles efforts. Nationally, interaction between human activities emerged as dominant factor, affecting approximately 56.8% area. Additionally, our projections varied future for trends. While areas with increasing account about 70.66% total area, regions decreasing trends or transitioning decrease represent 29.34%. Based study's findings, we recommend development tailored strategies aligned regional enhancement balance amidst address declining quality. insights highlight complex relationship context COP27, providing valuable guidance advancing sustainable goals protection
