Spatial and Temporal Change Pattern and Trend Prediction of Land Use in the Middle Reaches of the Yellow River
The continuous changes in land use patterns have profound impacts on the ecological environment and socio-economic development of the Yellow River Basin. Understanding the dynamic changes in land use in the middle reaches of the Yellow River Basin can provide a scientific basis for achieving sustainable development in the Yellow River Basin. This study is based on four periods of Landsat remote sensing data from 1995, 2005, 2015, and 2023 in the middle reaches of the Yellow River Basin. Obtain the spatial distribution of land use in the demonstration area through Support Vector Machine (SVM) and maximum likelihood method classification, and analyze the characteristics of land use change in the study area from 1995 to 2023 using quantitative indicators such as land use change and transition matrix. The Markov model was applied to predict the land use changes in 2025 and 2030. By establishing the FLUS-Markov model, the land use changes in the study area in 2025 and 2030 were predicted. For the six types of land use changes (forest, grassland, wetland, cultivated land, construction land, and unused land), the results show that: (1) Over the past nearly 30 years, cultivated land and forest land have decreased by 8 600 km2 and 6 400 km2 respectively, while the area of construction land has significantly increased by 7 500 km2; (2) The transfer directions of land use types are diverse, mainly from cultivated land to construction land and vegetation, and the landscape of each land type tends to be balanced in spatial distribution, with coordinated urban development; (3) Between 1995 and 2023, the number of forests, grasslands, and construction land showed an upward trend, while the number of wetlands, cultivated land, and unused land showed a downward trend; (4) In the next 10 years, there will be significant changes in land use in the middle reaches of the Yellow River, as humans require more land for construction.
