actual observations and simulated data of the Aral Sea

This dataset is primarily used to calculate and analyze the one-dimensional vegetation cover in the Aral Sea region, and to examine vegetation ecological changes in the region by integrating data on niche breadth dynamics. In addition, model simulations are employed to characterize changes in one-dimensional vegetation cover and niche breadth, and the simulated results are compared with actual observational data to evaluate model performance and further analyze the ecological changes in the Aral Sea region.
