Effects of Climate and Land Use Changes on Water Resources in the Taoer River

The changes of both climate and land use/cover have some impacts on water resources. In the Taoer River basin, these changes have directly influenced the land use pattern adjustment, wetland protection, connections between rivers and reservoirs, local social and economic development, and so forth. Therefore, studying the impacts of climate and land use/cover changes is of great practical significance. The Soil and Water Assessment Tool (SWAT) model is employed in this study. With historical measured runoff data and remote sensing maps of annual land use classifications, we analyzed the impacts of climate change on the runoff of the Taoer River. Based on the land use/cover classifications of 1990, 2000, and 2010, we analyzed the land use/cover change over the last 30 years and the contribution coefficient of farmland, woodland, grassland, and other major land use types to the runoff. This study can provide a reference for the rational allocation of water resources and the adjustment of land use structure for decision makers.
