Abstract: Based on the observational data of 3 meteorological stations in Minjiang estuary wetland from 1961 to 2006,the variation analysis of precipitation and temperature was conducted by using linear regression and Mann-Kendall method.The results showed that the annual average temperature from 1961 to 2006 increased obviously with the rate 0.26℃ per 10 years.Abrupt change occurred in 1994.The average temperature of each seasons increased,especially in winter,abrupt change occurred in 1990s and early 21st century.The annual precipitation changed little.To sum up,it was becoming warm-humid from cold-dry in Minjiang estuary wetland during last 46 years,whose advantage was bigger than disadvantage to local ecological system.
