| 英文简介 | Impacts of climate change and land use change on hydrology and water resources were one of the hot and front issues for global change. Based on theory and method of impacts of climate change and land use Change on water resources at home and abroad, applied statistical analyses method, spatial analyses method, remote sensing and GIS method and model analyses method, land use change were researched, and spatial-temporal variation characteristic and law of land use change were quantitatively analyzed in different period in Shiyang river basin. The variation characteristic of hydrology and meteorology were analyzed and studied, and long term variation trend of system evolution of water resources were researched, which spatial-temporal variation law of hydrology and meteorology were revealed in Shiyang river basin. Using SWAT model, distributed hydrological model of impacts of climate change and land use Change were built in Shiyang river basin. The impacts of climate change and land use Change and its variation scenario on water resources were simulated, and impact mechanism of climate change and land use Change on hydrology and water resources were revealed. The contribution rate and influence degree of impacts of climate change and land use change on runoff volume were quantitatively evaluated in Shiyang river basin, the action mechanism, collocation model,spatial distribution pattern and variation process of water resource were clarified, which would develop hydrology theory in arid area river basin and offered theoretically basis for with reason collocation and optimal use of water resource in arid area. |
