Abstract
Based on the dates of evaporative capacity with 20 cm diameter in Jiyang County from 1965 to 2010,this paper analyzed the evaporative capacity characteristics.The results showed that evaporative capacity of Jiyang County was decreasing year after year,the average descending range was 1.48 mm per 10 years.There was notable changes of evaporative capacity in the 80s of 20th century.Before 1980 s,the evaporative capacity was higher than average value.After 1980 s,the evaporative capacity was less than average value,and the average difference between this time periods was 424.8 mm.The evaporative capacity were decreasing in spring,summer,autumn and winter.Its decreasing propensity was different,which was closely related to the meteorological factors such as sunlight,temperature,precipitation and so on.关键词
