摘要
森林是陆地生态系统的主体,而森林覆盖率、森林蓄积量及森林生物量是森林资源重要的特征参数,亦是林业调查的主要指标。合成孔径雷达(SAR)以其独特的成像机制、全天候全天时的成像特点以及较强的穿透能力,在森林资源调查发挥着巨大的作用。文章主要概述了合成孔径雷达技术特点及其在森林覆盖率、森林蓄积量及森林生物量等林业调查中的应用现状,并探讨了目前存在问题及未来发展趋势。
Forest is the main body of terrestrial ecosystem, and forest coverage rate, forest stock and forest biomass are important characteristic parameters of forest resources and main indexes of forest investigation.Synthetic aperture radar(SAR) plays an important role in forest resources investigation with its unique imaging mechanism, all-weather and all-day imaging characteristics and strong penetrating ability.In this paper, the characteristics of synthetic aperture radar(SAR) technology and its application in forest investigation, such as forest coverage rate, forest stock and forest biomass, are summarized.
