摘要：为探究我国西南山区霜冻日数变化规律,以贵州省为例,利用1960—2013年全国0.5°×0.5°逐日最低气温格点数据,运用克吕格插值、变异系数和趋势倾向率等方法对全省1960—2013年霜冻日数时空变化特征进行了分析.53年间贵州省霜冻日数呈下降趋势.贵州省南部和东北部多年平均霜冻日数较少,西部和西北部较多.全省中西部霜冻日数变异系数较小,南部和东北部较大.霜冻日数与经度、纬度、高程之间的相关性不强.霜冻日数与高程、纬度呈正相关,与经度呈负相关.
In order to explore the variation of the frost days in southwest mountainous region. Based on 0.5~x0.5~daily temperature dataset from 1960 to 2013, this paper analyzed the spatial and temporal variations of the frost days in Guizhou province from 1960 to 2013 by the method of Kriging interpolation, variation coefficient and trend rate. A decline trend could be found for frost days in Guizhou province from 1960 to 2013. Frost days in south and northeast parts were relative low while were relative high in west and northwest parts. Variation coefficients of frost days in central and west parts were relative low while were relative high in south and northeast parts. There was a weak correlation between frost days and longitude, latitude and elevation.There was a very significant positive correlation between frost days and elevation and latitude while there was a significant negative correlation between frost days and longitude.
