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。
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 exis-ted across the agricultural region. Global warming and topography are the determining factors for temporal and spatial variation of ac-cumulated temperature in Guizhou Province.
