采用多种指标详细揭示１９９１／１９９２柑桔大冻的区域差异性以及对生物、人为、前期气候和当时低温等多方面致灾原因进行了深入细致的分析，此次冻害区域分布与１９５５、１９６９年类似，即鄂西南轻或未冻（０～２级）、峡外过渡区中等冻害（２～４级）、其它广大地区重冻（３～４级）．局部如鄂西北西端、大别山南至汉口以北严重受冻（４～５级）。１９９１年是大年，结果多，树体损耗大，前期罕见高温干旱，土壤板结，无法施还阳肥，树势弱；“柑桔热”下在不适宜区大量引种；管理粗放，未按抗寒栽培等等，且低温来得早，升降温幅度大，平流、辐射、融雪三方面降温效应叠加造成年极端低温出现，给我省柑桔业致命打击。本文根据此次冻害暴露的许多敏感问题进行了讨论并提出对策。
Using a variety of indicators to reveal in detail the regional differences of 1991/1992 citrus frozen and in-depth and detailed analysis of the causes of biological, anthropogenic, pre-climatic and then low temperature and other aspects of the disaster, the distribution of frost damage and 1955, 1969 The year is similar, ie mild or unfrozen (0 ~ 2 grade) in southwestern Hubei Province, moderate freezing damage (Grade 2 ~ 4) in transitional area outside Xia Gorge, and other regions (grades 3-4). Part of western Hubei, such as the western end of the Dabie Mountains to the north of Hankou severely frozen (4 ~ 5). 1991 is the New Year, the result is more, the tree body loss, rare high temperature and drought in the early stage, the soil compaction, can not be applied to Yangfei, tree potential is weak; “Citrus fever” in a large number of inappropriate introduction area; Cold cultivation and so on, and the cold comes earlier, the rate of increase and decrease of temperature, advection, radiation, snow melt three superposition of cooling effect caused by the emergence of extreme low temperature, citrus industry in our province fatal blow. This article based on the many sensitive issues of exposure to frost injury were discussed and proposed countermeasures.
