Analyzing ecological environment change and associated driving factors in China based on NDVI time series data

The ecological environment is the foundation of human survival and development. China’s ecological environment has undergone a historic transition from partial improvement to overall improvement. In this paper, long time series NDVI data (1998–2018) are used to evaluate the ecological environment ch...
