| 摘 要： | 基于1961—2010年全国0.5°×0.5°逐日气温格点数据,采用Kriging插值法等方法分析了1961—2010年贵州省积温的时空变化特征。结果表明:50 a间,全省≥0℃和≥10℃的积温呈增加的趋势,并呈现出西低东高的空间格局;随着高程的增加,≥0℃和≥10℃的积温逐渐降低;随着坡度的增加,≥0℃和≥10℃的积温先增加后降低;各农业区≥0℃和≥10℃的积温存在明显的空间异质性。气候变暖和地形是影响贵州省积温时空变化的重要因素。

| Abstract: | Based on 0.5°×0.5° daily temperature dataset in Guizhou Province during 1961-2010, temporal and spatial variations of accumulated temperature were analyzed by Kriging interpolation.The results showed that accumulated temperature for ≥0 ℃ and ≥10 ℃ increased in the past 50 years.Accumulated temperature for ≥0 ℃ and ≥10 ℃ was higher in the east than the west part.Accumulated temperature for ≥0 ℃ and ≥10 ℃ dropped with increased altitude.Accumulated temperature for ≥0 ℃ and ≥10 ℃ firstly increased and then decreased with elevated slope.Spatial heterogeneity for ≥0 ℃ and ≥10 ℃ accumulated temperature existed across the agricultural region.Global warming and topography are the determining factors for temporal and spatial variation of accumulated temperature in Guizhou Province. |
