中文摘要	过去40多年来，洮河流域主要产流区甘南高原的气候和生态环境发生了显著变化，通过对引洮工程的引水区流域上游40多年的实测水文气象数据的统计分析发现，降水和径流总体下降趋势非常明显，20世纪80年代至90年代降水径流减少更多，达35％；而气温则呈上升趋势，但上升幅度没有降水径流的下降幅度大。由于气候升温变暖、草原载畜过量以及过度砍伐森林，导致气候干旱化、山区水土流失加剧、草原植被退化和沙漠化，这一切都将对未来引洮工程发挥效益产生不利影响。
英文摘要	The middle region in Gansu Province is arid and most poverty in China. For solution this problem the China government has been dedicated to plan the Taohe River Water Diversion for Irrigation Project since 1950s. The upper reach of Taohe River is the water-taking region of the Project. But analysis on the past 50 years hydrolog-ical and meteorological data in Taohe River basin showed a slowly temperature-rising and precipitation-or runoff-decreasing trend. In the past 50 years the precipitation has decreased 43 ~67 mm and the temperature has increased 0.8 °C. Especially, the precipitation has been decreased by 10. 2% and the runoff by 35% from 1980s to 1990s. In the past 50 years the multi-annual average total surface and underground water resources quantity was 47. 16 x 108 m3 o a-1 in Taohe River basin. And in 1950s the quantity was 46. 25 x 108 m3 o a-1, but in 1990s the quantity was 33. 2 x 108 m3 o a-1. The decrease of precipitation, runoff and the increase of temperature had resulted in the climate drought and land desertification. Many wetlands or lakes disappeared in Gannan Grassland of Gansu province. All these will influence the Taohe River Water Diversion for Irrigation Project. It has significance to enhance the study on water resources influenced by climate change and present scientific references to this project design and governmental decision-making.
