Supplementary data for LUCC simulation and landscape ecological risk assessment in the Tarim River Basin

This dataset contains two supplementary tables supporting the study on multi-scenario LUCC simulation and landscape ecological risk assessment in the Tarim River Basin. Table S1 presents the parameter sensitivity analysis of the landscape ecological risk index (LERI). We adjusted landscape metric weights and land vulnerability values within reasonable ranges to test the stability of ecological risk results. The outcomes show slight fluctuations in average risk value and high-risk grid quantity under moderate parameter adjustments, accompanied by extremely high spatial correlation coefficients. Uniform scaling of vulnerability values only changes absolute risk values without altering the spatial pattern of ecological risk, which proves the LERI system is robust and effectively alleviates the subjectivity of parameter assignment. Table S2 displays the confusion matrix and classification accuracy indicators of the intPLUS land use simulation model validated with the 2020 actual land use data. Producer’s accuracy, user’s accuracy for each land use type, overall accuracy and Kappa coefficient are listed. The model achieves excellent overall simulation performance. Slightly lower accuracy of water bodies and construction land is attributed to fragmented small patches and frequent conversion with surrounding unused land, which is a typical feature of arid inland river basins and does not affect the reliability of subsequent scenario simulation results.
