低温冷害监测评估及风险区划研究进展

Monitoring assessment and risk regionalization on low-temperature damage

概述了我国现有的低温冷害监测评价指标,归纳了确定低温冷害指标的方法,介绍了国内外有关低温冷害风险评估的研究进展。低温冷害在国外的研究大多表现在冷害机理方面,而在冷害环流、冷害时空分布、冷害监测与预警方面的研究所占比例很小。关于低温冷害风险,国内大都从低温冷害出现的风险概率和风险指数着手,研究风险评估。通过对低温冷害的研究,能有效的降低这种灾害产生的风险,为低温冷害的监测评估和风险区划研究的进一步发展提供了有力的依据。

This paper summarizes the existing low-temperature damage monitoring evaluation index inour country, induces the method to determine low-temperature damage index, and introduces thedomestic and foreign related research progress of low-temperature damage risk assessment. Abroadresearch about low-temperature damage focuses on the mechanism of chilling injury and does lessresearch in.circulation, space-time distribution, monitoring and early warning for chilling injury. Andabout the low-temperature damage risk, domestic research of the risk assessment starts mostly fromrisk probability and risk index. Through the study of low-temperature damage, the risk produced fromsuch disasters can be effectively reduced, and provides powerful basis for further development ofmonitoring,evaluation and risk regionalization for low-temperature damage.
