Abstract:

The Yellow River Basin bears an important ecological, economic and cultural strategic position in China, and its ecological environment is a vital foundation for ensuring the high-quality development of the Yellow River Basin. In this study, the long-term sequence of Remote Sensing Ecological Index (RSEI) of the Yellow River Basin was used to dynamically monitor and analyze the ecological quality changes in the Yellow River Basin in the past 20 years. The RSEI mean value is 0.497 from 2001 to 2019, increasing 0.04, which shows a trend of overall improvement and slight fluctuations. Moreover, its influencing factors were analyzed from three aspects: natural factors, policy measures and socio-economic factors. The complex natural factors bring difficulties to the governance of the Yellow River Basin, and the socio-economic factors such as continuously increasing population and night light data correspondingly disturbed the ecological environment changes, while the ecological protection policies and restoration measures play a positive role.

Key words: RSEI, Yellow River Basin, ecological environment, dynamic change, influencing factors
