Abstract
Based on the background of the mid-upstream basin of Luanhe River that mainly consists of mountainous topography,rapidly-varied terrain,multi-type of land utilization and physiognomy and complicated eco-environment,the impacts from the land utilization types and the variations of the precipitations in various sub-basins in the river basin on the runoff variations of all the sub-basins are analyzed on the basis of the multivariable linear regression model for studying the impacts from land utilization types on the runoff variation of the river basin.The result shows that the impacts on the runoffs of Baohe and Liuhe River Sub-basins located on the downstream of Luanhe River are quite significant,while the runoff variations of all the sub-basins along the mid-upstream basin of Luanhe River are mainly impacted by the area variations of the grass-lands,water areas and forest lands therein.Therefore,there are larger differences among the drivings from the precipitations and all the land utilization types in the different sub-basins on the runoff variation of the river basin,which must be individually discussed and analyzed during the planning and design of the water conservancy project concerned.关键词
