摘要

Land development and urbanization have increased significantly in Taiwan over the last two decades because of the increasing population and economic development. The ungauged Ta-Chou basin, which is representative of drainage basins undergoing these changes, was chosen to investigate the effects of land-use change on surface runoff. Supervised classification of Landsat MSS and SPOT satellite images was used to show land-use change from 1972 to 2000. During this period, the area of impervious land increased by approximately 220%, and the area occupied by rice paddies decreased by about 55%. Results from a distributed rainfall-runoff model reveal that the observed land-use change causes increases in both peak discharge and total runoff. For design storms having return periods ranging from 10 to 200 years, peak discharge increased from 6 to 10% and total runoff increased from 10 to 17%. The methods outlined may be used to investigate the effects of land-use change on runoff response in ungauged basins elsewhere.
