The Yellow River Basin plays an important role in China's economic development and ecological protection. Based on remote sensing ecological index (RSEI) data, climate data, digital elevation data, and night-time remote sensing data, the RSEI index was used as the ecological environment quality evaluation index. such as Theil Sen slope estimation, Hurst index, and Mann-Kendall test were used to evaluate the spatiotemporal changes in the ecological environment quality of the Yellow River Basin from 2001 to 2021. Geodetectors were used to quantitatively detect and analyze the key factors and their interactions in the ecological environment of the basin. The results showed that: Firstly, the overall ecological environment quality in the Yellow River Basin was slightly lower than the moderate level and gradually improved from the northwest to the southeast. The areas with moderate and lower grades accounted for 83.12% of the total area in the basin. The ecological environment quality has shown an upward trend in the past 21 years, which was confirmed by a significance test with a confidence level of 95%. Secondly, the ecological quality within the region showed a phased change of rising decreasing rising, with frequent area transfer between adjacent ecological levels and migration of ecological positions at different levels. The proportion of ecological improvement areas in the past 21 years reached 58.09%, but 51.75% of the regional improvement trend did not pass the significanc...
