Abstract: Four conventional stations were selected to analyze the characteristics of the climate change from 1961 to 2010 in estuary wetland of Minjiang river during the recent 50 years, as well as its impacts on the wetland. The results showed that the temperature of Minjiang river estuary wetland presented an increasing trend significantly. The precipitation of the wetland considerably fluctuated and increased，but not significantly. The regional thermal index of the wetland showed an increasing trend significantly, and the regional moisture index showed an increasing trend in the mass, but the extent of increase was lesser. Overall, the climate would tend to be warmer and wetter in Minjiang river estuary wetland, but the climate change trend was less obvious. The results provided important references for the conservation, rational exploitation and utilization of the wetland.
