中文摘要：

土地利用/覆被的变化（Land Use/Land Cover Change,LUCC）直接体现和反映了人类活动的影响程度,它对水循环过程的影响结果十分显著。本文利用SWAT模型定量解析土地利用/覆被变化对蒸发、径流等水循环要素的影响。研究表明,1995-2000年海河流域的土地利用覆被变化很大,土地利用/覆被变化对SWAT模型水循环模拟结果的影响也是很大。人类活动对于海河流域的影响总体上是流域蒸发量在增加、而地表与地下径流和土壤水量在减少。

英文摘要：

The land use/cover change（LUCC） directly incarnates and represents the influence of the human activities,and produces quite significant effects on the hydrological cycle.The LUCC influence on hydrological cycle factors such as ET,runoff and so on was quantitatively simulated for Haihe river basin.The simulation results show that,a great LUCC change of this basin occurred during the period from 1995 to 2000,and this change produced tremendous effects on the results of SWAT hydrological simulation.A general response of Haihe river basin to the human activities is the increasing of ET,the decreasing of surface runoff and underground runoff,as well as the decreasing of soil moisture content.
