摘　　要：对作物冷害指标、风险及损失评估、监测和预报,以及近年来业务化应用的研究成果进行总结和归纳,比较了这些领域新老研究方法的优缺点。重点介绍3S技术和作物模型在这些领域的应用。探讨了遥感温度反演与冷害监测相结合的可行途径,作物模型用于区域冷害损失评估所需的尺度转换及相应冷害模块添加等问题。明确了新技术与冷害研究相结合过程中需要重点考虑和解决的关键技术难题。可为冷害研究的技术革新提供参考。The advances in the study of cold damage indicators, cold damage monitoring, risk and loss assessment, cold damage forecast and business application were summarized in this paper. Comparison was carried out to their advantages and disadvantages of the traditional and new research methods in these areas. The application of 3S tech- nology and crop model in cold damage research was mainly introduced. The possible ways that combined remote sensing with cold damage monitoring was investigated in cold damage research. These issues were discussed such as crop model scale conversion and cold module adding at regional cold damage loss assessment. The challenges and difficulties in further research were also proposed. The results could provide reference for technical innovation of cold damage research.
