- Abstract:
-
According to the daily meteorological data of 72 stations in Heilongjiang Province from 1961 to 2012, the change characteristics of the whole year, the four seasons, the interdecadal temperature, the precipitation, sunshine hours and other main agricultural climate resources were analyzed by linear trend coefficient method. Results show that the average temperature in Heilongjiang Province is obviously increasing and the rise rate is 0.35℃/10 a. Winter is the main contribution to the temperature increase, average of every 10 years increased by 0.52℃. The interdecadal change of the whole year and the average temperature of seasons is increasing, and which is the most obvious in 2000s. The annual precipitation of Heilongjiang Province is at the fluctuation with decreasing rate of 2.76 mm/10 a, so the trend is not obvious. But the seasonal variation is obvious, especially the autumn. The interdecadal change of annual and seasonal precipitation is different. Both the whole year and seasonal sunshine hours are decreasing. The annual and seasonal sunshine hours showed a trend of non-uniform reduction with the interdecadal change.
