Abstract:: The timely and accurate monitoring and evaluation of eco-environmental quality in the Yellow River Basin is the basis of its eco-environmental protection and construction. We took the ten sections of the Yellow River in Inner Mongolia as the research objects, taking the top Ten Kongdi in Inner Mongolia of the Yellow River Basin as the research objects, we used Landsat5 TM and Landsat8 OLI data, to analyze the distribution pattern and change trend of eco-environmental health in the study area from 2000 to 2020 based on ecological remote sensing index. The results showed that:(1)in 2000, 2010 and 2020, the average values of remote sensing ecological index of the Ten Kongdui were 0.31, 0.33 and 0.57, respectively, and the ecological environment quality improved continuously;(2)during the study period, the eco-environmental quality grades of the ten kongdui were mainly from poor to general, and the sum of poor, relatively poor and general areas accounted for 79.45%, 76.54% and 70.16% of the whole study area; the area was constantly decreasing, and the area transferred to good and excellent grade reached to 1 004 km²;(3)in terms of spatial distribution, the eco-environmental quality of lower plain was the best, followed by the upstream hilly area and sandy area of middle reaches. On the whole, although the ecological environment governance in the study area has achieved some results, there is still much room for improvement.
