    Abstract

    Land use/cover change (LUCC) is one of global environmental change hot issues. The study of land-use changes in the Yiluo River Basin is significant to ecological protection and high-quality development of the Yellow River Basin. Based on long-term LandsatTM satellite remote sensing images, R language string diagram visualization model and linear model redundancy analysis(RDA analysis), this paper analyzed the temporal and spatial change characteristics of land use, land cover flow rate, directionand internal driving factors in the Yiluo River Basin from 1990 to 2020. The results showed: (1) From 1990 to 2020, the land change in the Yiluo River Basin showed a trend of change in forest land firstly decreasing and then increasing, arable land first increasing and then decreasing, construction land increasing as a whole, and water area decreasing as a whole. (2) In terms of quantity Every 10 years from 1990 to 2020, the total amount of change in cultivated land and forest land is the largest, followed by construction land, and the amount of change in water, grassland and unused land are very small. (3) 1990—2000, 2000—2010, 2010—2020 The mutual conversion activity of land use types and the degree of land-use change showed an upward trend, reaching the highest in 2010—2020. (4) From 1990 to 2020, the center of gravity of forest land shifts to the northeast as a whole, and the center of gravity of cultivated land migrates to the south. The change in the center of gravity of forest land and cultivated land is related to the policy of returning farmland to the forest. The construction land is generally centered around the main urban area of Luoyang City, which is related to the direction of social and economic development and urban development; (5) In terms of the driving force, rapid economic development is the main driving force for the change of land use area in the Yiluo River Basin. The promulgation and implementation of the policy of returning farmland to forest is the main reason for the change of forest land and cultivated land area. The results of this study can provide a scientific basis for the ecological protection and sustainable development of the Yellow River Basin.
