摘要
使用每 10年为 1个年代段 ,对湖北省气温和有效积温资料进行分析。结果表明 ,80年代以来 ,湖北省气候变化的特点是冬季变暖夏季变凉。水稻生育期间有效积温变化是山区以减少为主 ,平原地区以增加为主。 1980年以后水稻生育期内有效积温的年际波动比 1980年以前大 ,在气候偏冷年份将导致有效积温严重不足 ,水稻生育期延长 ;在气候偏暖年份 ,则出现生育期缩短 。
By analysing temperature and effective accumulated temperature (EAT) of Hubei province, it is discovered that climate variation in Hubei Province is warmer in winter and cooler in summer since 1980's. The change of the EAT in rice growth period(RGP) mainly decreases in mountains and increases in plains; it leads to prolong(reduce) RGP in mountains (plains). The yearly fluctuations of EAT in RGP after are 1980 greater than before; which causes EAT serious shortage and RGP prolonged in cooler year and RGP reduced and rice quality no good in warmer year. \;
