Abstract

Abstract:

Based on the daily average temperature data from 1970-2019 at 11 meteorological stations in the Great Khingan forest area of Inner Mongolia, we analyzed the temporal and spatial variation characteristics of accumulated temperature under the background of climate change. MK mutation test and wavelet analysis were used to study the changes of the initial date, termination date, continuous days and accumulated temperature under different boundary temperatures. The results showed that the first day of positive accumulated temperature was advanced and the last day was postponed; the negative accumulated temperature showed the opposite trend. In terms of time, the variation range of accumulated temperature at different boundary temperatures was different, but as a whole, it showed an increasing trend due to the change of continuous days, and the variation trend of each station was basically the same as that of the whole stations. The positive accumulated temperature mutated around 1994, rose significantly in the later period and passed the 0.05 level significance test. There were multiple mutation time points in the negative accumulated temperature in 1980s. The cyclical changes of each accumulated temperature fluctuated significantly within the 2 a scale. Spatially, latitude and altitude had obvious effects on the variation of accumulated temperature, and the overall accumulated temperature decreased from south to north, and the accumulated temperature in Aershan decreased due to the influence of altitude.

Key words: the Great Khingan forest area, boundary temperature, accumulated temperature, continuous days
