根据葫芦岛市日光温室内、外的气象观测资料,分析了日光温室内最低气温与室外最低气温的关系,定义了日光温室蔬菜生产低温寡照灾害的指标,以此构建了低温寡照灾害风险评估模型,并从灾害风险概率、灾害频率等角度综合评估了葫芦岛市日光温室蔬菜生产低温寡照灾害的风险水平。结果表明:绥中县是葫芦岛市日光温室蔬菜生产低温寡照灾害的低风险区,市区为中风险区,兴城和建昌是高风险区;日光温室蔬菜生产受低温灾害影响的风险要明显高于寡照灾害,在1981~2013年期间,葫芦岛市平均每年出现日光温室低温灾害10.6次、寡照灾害1.8次;低温寡照灾害类型以轻度灾害为主;低温灾害仅在冬季出现,1月出现次数最多;寡照灾害在各月均可能出现,以5月和11月出现次数较多。
根據葫蘆島市日光溫室內、外的氣象觀測資料,分析瞭日光溫室內最低氣溫與室外最低氣溫的關繫,定義瞭日光溫室蔬菜生產低溫寡照災害的指標,以此構建瞭低溫寡照災害風險評估模型,併從災害風險概率、災害頻率等角度綜閤評估瞭葫蘆島市日光溫室蔬菜生產低溫寡照災害的風險水平。結果錶明:綏中縣是葫蘆島市日光溫室蔬菜生產低溫寡照災害的低風險區,市區為中風險區,興城和建昌是高風險區;日光溫室蔬菜生產受低溫災害影響的風險要明顯高于寡照災害,在1981~2013年期間,葫蘆島市平均每年齣現日光溫室低溫災害10.6次、寡照災害1.8次;低溫寡照災害類型以輕度災害為主;低溫災害僅在鼕季齣現,1月齣現次數最多;寡照災害在各月均可能齣現,以5月和11月齣現次數較多。

According to the meteorological observation data in solar greenhouse and open field of Huludao city , we analyzed the relationship between the minimum air temperature in solar greenhouse and the outdoor minimum air temperature , defined some inde-xes for the evaluation of low-temperature and few-sunshine disaster in vegetable production in solar greenhouse , constructed several models for the risk assessment of low-temperature and few-sunshine disaster , and comprehensively assessed the risk level of low-temperature and few-sunshine disaster in vegetable production in solar greenhouse of Huludao city from the view points of disaster risk probability, disaster frequency and so on .The results indicated that:as for low-temperature and few-sunshine disaster in vege-table production in solar greenhouse of Huludao city , Suizhong county was a low-risk district, the urban area was a middle-risk dis-trict, and Xingcheng and Jianchang county were two high-risk districts.The risk level of low-temperature disaster in vegetable pro-duction in solar greenhouse was obviously higher than that of few -sunshine disaster.During 1981~2013, averagely 10.6-times low-temperature disaster and 1.8-times few-sunshine disaster appeared in solar greenhouse of Huludao city within a year .The type of low-temperature and few-sunshine disaster mainly was mild type .Low-temperature disaster happened only in winter and mostly in January.Few-sunshine disaster happened in all months of vegetable growth stage , and appeared mostly in May and November .
