Abstract
[Objective] The research aimed to analyze temporal-spatial distribution and change trend of the temperature in Beibei District. [Method] Based on temperature observation data at 6 ground meteorological observatories in Beibei District front 1951 to 2010, EOF and linear trend method were used to analyze temporal-spatial distribution and change characteristics of the temperature in Beibei District in recent 60 years. [Result] Temperature in Beibei District in recent 60 years overall presented rise trend, and average rise velocity was 0.045 ℃/10a. Temperature rise in autumn was the most obvious, while summer temperature presented decline trend. Average temperature presented gradual rise trend from January to July and gradual decrease trend from August to December. Seen from spatial distribution, temperature in the whole district was higher in the west and lower in the middle. Abnormal spatial distribution of the average temperature in the whole district mainly had consistent higher (lower) type, south-north reverse type and east-west reverse type. [Conclusion] The research provided theoretical basis for effective disaster prevention and reduction in the zone.关键词
