摘要: 玉米是辽宁省第一大粮食作物,研究玉米低温冷害与霜冻灾害的发生规律及风险评估,对防御与温度有关的灾害和保证玉米安全生产意义重大。本文利用1961-2010年辽宁省49个气象站的日平均气温、日最低气温及玉米观测资料,对玉米低温冷害和霜冻灾害风险评价指标进行选取与量化,从灾害的危险性、暴露性和脆弱性方面对灾害的发生风险进行综合分析,并对玉米低温冷害和霜冻灾害进行风险评估及区划。结果表明:辽宁省玉米低温冷害的高风险区主要位于西丰和昌图东部地区,中风险区主要位于辽北和辽东大部地区,其他大部地区则为低风险区或次低风险区。辽宁省玉米霜冻灾害的次高和中等风险区位于建平、西丰及抚顺的清原与新宾地区,低风险区位于环渤海一带及辽南地区。在气候变暖背景下,对辽宁地区玉米低温冷害和霜冻灾害仍需重视。

Abstract: Maize is an important crop in Liaoning province with the largest planting area and highest yield comparing to the other grain crops.Studies of regularity and risk on maize cold damage and frost damage are of vital importance for defending the disasters related to temperature and insuring the maize production security.Based on the daily temperature, the minimum temperature, maize planting area, maize yield at 49 weather stations of Liaoning province, the evaluation indexes and its value of maize cool damage and frost damage were determined.Then the integrated analysis of maize cold damage and frost damage was conducted from the respect of disaster hazard, disaster exposure and disaster sensitivity.Finally, the risk assessment and regionalization of cold damage and frost damage were investigated.The results show that the high-risk region of maize cold damage is located in Xifeng and east of Changtu.The middle-risk region is in the north and east of Liaoning province and the other places are attributed to low-risk region.For maize frost damage, the high-risk region is located in Jianping, Xifeng, Qingyuan and Xinbin, while low-risk region is in coastal areas and south of Liaoning province.In conclusion, under the background of climate warming, the more attention is still required on maize cold damage and frost damage.

Key words: Maize, Cold damage, Frost damage, Risk regionalization
