Abstract:

Characteristics of sunlight, temperature, extreme lowest temperature and precipitation of Minjiang river estuary wetland during years and its impacts on the wetland were analyzed, based on meteorological data from 1971 to 2004 of 4 conventional stations in the wetland. The results showed that from 1971 to 2004, annual temperature and seasonal temperature were significantly increased with the highest rate in winter and the lowest in summer. The sunlight hours decreased and the extra lowest temperature and precipitation of year and all the four seasons except spring increased, but all with not significantly trends. Furthermore, Changes of sunlight hours and precipitation were obvious. Climate change among years had different positive and negative impacts on the eco-environment. The results provided important references for the conservation, rational exploitation and utilization of the wetland.
