Research on Evaporation Characteristics and Their Variation Tendency in the Source of the Yangtze River and the Area Around

By analyzing a series of evaporation data from 10 meteorological stations and gauging stations, such as stations on the Tuotuohe River, in the source of the Yangtze River and the area around during the period from the year they had been established to 2000, this paper gives characteristic values of evaporation and their variation regularity within a year and inter years, and studies the variation tendency of evaporation in the area.
