摘要: 利用区域气候模式PRECIS(Providing Regional Climates for Impacts Studies)输出的SRES A1B情景的日平均气温资料,预估2011-2100年贵州省稳定通过10℃的农业热量资源变化趋势。结果表明:A1B情景下,2011-2100年贵州省≥10℃初始日期明显提前,终止日期明显延后,持续天数和积温显著增加,热量资源的增加趋势东部高于西部;相对气候基准时段,未来90a的初始日期在毕节、六盘水和黔西南地区提前幅度最大(16~18d),终止日期在大部地区延后14~19d,持续日数在西部增加31~38d,东部增加23~30d,而积温在整个贵州预计升高878~1162℃·d;至2080s时段,4000℃·d等值线预计将从气候基准时段的仁怀—开阳—龙里—普定—晋安—兴义一线向东位移至高海拔地区威宁、赫章境内,而6000℃·d等值线预计将从南、北两方向逐步向贵州中部推进,2080s时段北部等值线将位移至仁怀—遵义—凤岗—沿河一线,而南部将位移至安龙—六枝—惠水—瓮安—雷山—三穗—铜仁一线。

Abstract: The daily mean temperature from regional climate model system PRECIS (Providing Regional Climate for Impacts Studies) under SRES A1B scenario was calculated to project the tendency of agricultural thermal resources in Guizhou province during 2011-2100The results showed that under A1B scenario,the beginning date steadily above 10℃ would advance significantly,while the ending date might delay also obviously,and an evident increment would be performed both in the lasting days and accumulated temperature Meanwhile,the increasing trend of agricultural thermal resources in the east might be higher than in the west during 2011-2100Compared with baseline,in next 90 years,the biggest advancement of beginning date steadily above 10℃ might be showed in Bijie,Liupanshui and southwest Guizhou region (16-18d),and the ending date of most areas would delay 14-19d,in terms of lasting days,the increment of 31-38d and 23-30d might be represented in the west and east,respectively Accumulated temperature in Guizhou province would also be expected to elevate 878-1162℃·d As far as contour change be concerned,4000℃·d  contour might move eastward from Renhuai-Kaiyang-Longli-Puding-Jin′an-Xingyi line in baseline to high altitude region as Weining,Hezhang in 2080s period,while 6000℃·d contour would be expected to gradually advance to the central Guizhou from northern and southern directions,in 2080s period,the northern contour might shift to Renhuai-Zunyi -Fenggang-Yanhe line,and southern contour might move to An′long-Liuzhi-Huishui-Weng′an-Leishan-Sansui  Tongren line
