摘要
Abstract
Since 1990s,the Yellow River water amount has shown partial dry trend in general. Dry years and partial dry years mostly occurred at Huayuankou Hydrological Station within the 22 years from 1990 to 2011,sometimes normal years occurred. The characteristics of day years and partial dry years in most years were synchronized with Longyangxia Hydrological Station in upper reaches,but in specific years partial dry years oc-curred in lower reaches,meanwhile wet years occurred in upper reaches,which was propitious to multi-year regulation of large-scale reservoirs in upper reaches to supplement water shortage and satisfy agricultural and ecological water demand. Dry period and partial dry period of continuous 9 years from 1994 to 2002 occurred. Compared with the historical continuous dry period of 11 years from 1922 to 1932,the dry degree and duration of the latter was more severe. Therefore water regulation pre-arranged plan should be prepared to prevent longer continuous dry period.关键词
