【摘要】 应用东北地区1961-2000年水稻产量和温度资料,建立了东北地区水稻延迟型冷害和障碍型冷害发生的气象指标,分析了各地热量条件变化、水稻延迟型冷害发生的气候风险概率和障碍型冷害发生的频率,进行东北地区水稻低温冷害气候风险分区。结果表明, 吉林省东部和黑龙江省北部水稻栽培低温冷害的气候风险最高,黑龙江省三江平原、吉林省东部半山区水稻冷害风险也比较高,黑龙江省中南部和吉林省中北部风险程度居中,吉林省中、西部和辽宁省北部为较低风险区,辽宁省大部为低风险区。更多还原

【Abstract】 Based on data of temperature and rice yield from 1961 to 2000,meteorology indexes for rice chilling damage of prolong-type and sterile- type were built up,heat condition and climate risk probability of the two types of rice chilling damages were analyzed,and climate risk area was subdivided in Northeast China. Results showed that the east of Jilin Province and the north of Heilongjiang Province were the highest-risk areas for rice planting,the Three River Plain in Heilongjiang province and the eastern hilly land of Jilin Province were the higher-risk areas,and the southern and middle region of Heilongjiang and middle of Jijin were middle-risk areas. The western Jilin and northern Liaoning were lower-risk ar- eas. Most of Liaoning province was the lowest-risk area.更多还原
