| 摘 要： | 利用重庆市1984 ～2013年12月～次年2月的逐日最低气温资料,在考虑海拔高度的影响下,模拟分析了极端冻害在重庆市晚熟柑橘适宜区的时空分布规律以及风险等级.结果表明,在重庆市晚熟柑橘适宜区,极端冻害多出现在12月下旬,发生的程度一般为轻度冻害,发生的面积约占适宜区总面积的1/4左右,发生的概率一般低于4％,东北部的梁平、忠县、奉节、云阳等地和中部的垫江、长寿以及西部的合川、江津、渝北等地冻害发生的风险较低.重庆市长江沿岸海拔400m以下的大部地区,适宜晚熟柑橘栽培,但部分地区仍需要做好冻害防御.

| Abstract: | By using the daily minimum temperature during December to February from 1984 to 2013 in Chongqing, based on effect of altitude, spatial and temporal distribution and risk levels of simulate analysis of extreme freezing injury of late-maturing citrus in winter were completed. The results showed that extreme freezing injury of late-maturing often occurred in late December, and a lesser degree of occurrence, the percentage of total suitable area was 25%, and probability was less than 4%. Low-risk areas included Liangping, Zhongxian, Fengjie and Yunyang etc in Northeastern Chongqing and Dianjiang, Changshou in centre region of Chongqing, and Hechuan, Jiangjin, Yubei in Western Chongqing. Latematuring citrus were suitable in most areas below the altitude of 400 meters along the Yangtze River in Chongqing, defense of freezing injury was premeditated yet. |
