        摘要 利用1961—2015年山東省17個(gè)氣象站點(diǎn)和山東省周邊12個(gè)氣象站點(diǎn)的日平均氣溫資料和該區(qū)域的DEM(數(shù)字高程模型)數(shù)據(jù),采用混合插值方法和線性傾向估計(jì)方法,對山東省≥0 ℃初、終日、持續(xù)日數(shù)和積溫的時(shí)空變化特征進(jìn)行分析。結(jié)果表明,山東省≥0 ℃初日的空間分布呈現(xiàn)南部早、北部晚、山區(qū)早和平原地區(qū)晚的特征;≥0 ℃終日的空間分布呈現(xiàn)南部、沿海地區(qū)晚和中部、北部地區(qū)早的特征;≥0 ℃持續(xù)時(shí)間的空間分布為南部、沿海地區(qū)長,中部山區(qū)、內(nèi)陸及北部地區(qū)短;≥0 ℃積溫空間分布特征為由西南向東北逐漸降低。近55年來山東省17個(gè)氣象站≥0 ℃初日均呈現(xiàn)提前趨勢,平均氣候傾向率為2.74 d/10 a,且除煙臺外,其他站點(diǎn)的提前趨勢均達(dá)到顯著水平;≥0 ℃終日的變化未呈現(xiàn)明顯的規(guī)律,且所有站點(diǎn)的變化趨勢均未達(dá)到顯著水平;≥0 ℃持續(xù)時(shí)間和積溫均呈現(xiàn)增加趨勢,其氣候傾向率分別為4.33 d/10 a和65.86(℃·d)/10 a,且除菏澤、兗州、日照、青島、煙臺和威海的≥0 ℃持續(xù)時(shí)間的變化未達(dá)到顯著水平外,其余站點(diǎn)≥0 ℃持續(xù)時(shí)間和積溫的變化趨勢均達(dá)到顯著水平。

        Analysis of Spatiotemporal Variation Characteristics of Heat Resources at above 0 ℃ in Shandong Province Based on GIS

        Abstract The daily average temperature data from 17 meteorological stations in Shandong Province and 12 meteorological stations around Shandong Province from 1961 to 2015, and the digital elevation model (DEM) data were used to analyze the spatial and temporal variation characteristics of heat resources of above 0 ℃ in Shandong Province. A combination of the multilinear regression analysis and the inverse distance weighted method was used to analyze the spatial distributions of heat resources of above 0 ℃. The method of linear regression was used to identify the presence of trends of heat resources of above 0 ℃. The results showed that: The spatial distribution of the beginning date of above 0 ℃ was come early in the south and the coastal areas, but late in the north and the inland areas of Shandong Province. The spatial distribution of the ending date of above 0 ℃ was come late in the south and the coastal areas, but early in the middle and the north of Shandong Province. The duration of above 0 ℃ was longer in the south and the costal than in the north and the mountainous area of the central of Shandong Province. The spatial distribution of the accumulated temperature of above 0 ℃ was high in the southwest areas and low in the northeast areas in Shandong Province. During the past 55 years, the time series of the beginning date of above 0 ℃ showed negative trends for 17 meteorological stations with the average rate of -2.74 d/10 a, and except for Yantai station, the advance trend of other stations reached a significant level.The time series of the ending date of above 0 ℃ did not show obvious regularity, and the trend of change of all stations did not reach a significant level.Both the duration and accumulated temperature above 0 ℃ showed an increasing trend, and their climatic tendency rates were 4.33 d/10 a and 65.86 (℃·d)/10 a, respectively,and except for the changes of the duration above 0 ℃ in Heze, Yanzhou, Rizhao, Qingdao, Yantai and Weihai did not reach a significant level,the change trend of the duration and the accumulated temperature above 0 ℃ in other sites reached a significant level.
