摘 要：It is obvious that the climatic trend in the Western China is warming-drying in recent fifty years,especially in Yellow River Basin. Under the impact of climate change and human s activities,its fragile ecosystem became more *** River is one of the main tributary of the Wei River and second-grade tributary of tYellow River. Jing River originated from the Loess Plateau,and its full length and basin area are 455.1 km and 45421 *** on meteorological,hydrographic and remote sensing data collection of nearly fifty years （1955-2002）,this paper applied the SWAT MODEL （Soil and Water Assessment Tool） to research ecosystem characteristics of Jing River Basin on the conditions of climatic warming-drying trend and aggravated human activities,The impact degree between climate change and human activities to the soil and water resources of Jing River Basin from 1955 to 2002 were 2/3,especially in 70s～80s,land use and land cover change caused by human activities had much influences on the runoff..Aim to increasing water resources to adapt climatic warming-drying trend in Jing River Basin,the land use patterns were extracted.
