摘　　要：湖冰是气候变化的指示器,其中湖冰物候与短期或长期的全球变暖、大气变化、大洋涛动等相关性显著。湖冰物候期的提取是分析湖冰对全球气候响应规律的基础,也是研究全球气候变化的重要组成部分。传统以人工或气象站点观测的湖冰物候事件的方法无法满足研究需要,遥感技术尤其是多光谱遥感提供了强有力的技术支撑。本文以湖泊冰物候事件为基础,总结了湖泊冰物候定义的四种方法;再由遥感湖冰监测的机理,指出湖冰的反射光谱特征,在此基础上综述多光谱遥感监测湖冰物候的方法,并对比几种方法的优劣。本文是利用多光谱遥感技术提取湖泊冰物候的重要依据,为遥感在湖泊冰物候变化监测和气候变化响应研究中的应用奠定了基础。Lake ice is an indicator of climate change, in which the phenology of lake ice is significantly correlated with global warming, atmospheric change and ocean oscillation in the short or long term. The extraction of lake ice phenology is the basis of analyzing the response of lake ice to global climate, and it is also an important part of studying global climate change. The traditional methods of observing lake ice phenological events by artificial or meteorological stations cannot meet the needs of research nowadays. Remote sensing technology, especially multispectral remote sensing, provides powerful technical support. Based on the lake ice phenological events, this paper summarizes four methods for the definition of lake ice phenology. Then, based on the mechanism of monitoring lake ice by remote sensing, the reflection spectrum characteristics of lake ice are pointed out, and the methods of multi-spectral remote sensing monitoring lake ice phenology are summarized, and the advantages and disadvantages of several methods are compared. This paper is an important guide for the extraction of lake ice phenology by using multispectral remote sensing technology, which is the basis of the application of remote sensing to the monitoring of lake ice phenological changes and the study of the response to climate change.
