震后区域气温时空变化分析—以四川省为例 Regional Spatial and Temporal Variation Analysis of the Temperature after the Quake—Case Study of Sichuan Province

Abstract

本文使用克里金插值方法利用四川省1963~2013年的气温数据为基础，对四川省近50年的气温时空变化特征进行分析，并着重分析了1976年和2008年大地震前后区域气温变化。结果表明，过去五十年的整体趋势呈上升状态，温度上升趋势在2003年之后异常迅速。从1975~1977年及2007~2009年气温数据对比结果来看，1976年和2008年地震发生时，气温都发生了突变下降，在1976年气温发生突降后，1977年气温又迅速上升到与1975年的相似水平；而2008年地震发生，气温相对于2007年发生了突降，在之后的几年，气温总体都呈下降趋势，说明了地震会对气温产生了一定的影响。 This article uses the Kriging interpolation method and the temperature data of 1963-2013 in Si-chuan province to analyze spatial and temporal variation characteristics of air temperature in Si-chuan province nearly 50 years. It also emphatically analyzes the temperature change before and after the earthquake in 1976 and 2008. The results show that the overall trend is rising over the past 50 years and the temperature rises exceptionally rapidly after 2003. The temperature drop is mutated from the contrast temperature data when the earthquake occurred. For example, it has a sudden drop in temperature in 1976, then the temperature rise rapidly to similar to the 1975. It has a sudden drop in temperature in 2008 after the earthquake relative to 2007 and the tempera-ture generally has a downward trend in subsequent years, so we get the result that the earthquake has a certain influence on the temperature.
