摘要
利用实测资料,分析了江西省近43年来(1961-2003年)夏秋季高温干旱出现的站次、发生频率及时空分布特征。研究发现:夏秋季高温干旱累计站次与晚稻产量呈显著的负相关关系。当高温干旱累计≥120站次时,晚稻减产显著,发生频率高达85.7%;高温干旱累计≥77站次时,每增加10站次,晚稻减产8.09kg/hm2。
The occurrence frequency, spatial and temperal distribution of high temperature and drought in summer and autumn during 1961 - 2003 in Jiangxi Province were analyzed. It was found that the late rice yields were negative related with the accumulative times of the high temperature and drought in summer and autumn. The late rice yield would significantly reduce when accumulative times of the high temperature and drought over 120 stations or times with the occurrence frequency by 85.7 %. When the high temperature and drought were accumulated over 77 stations or times, the late rice yield would decrease by 8.09 kg/hm^2with increase of each 10 station or time occurrences of the high temperature and drought.
