成都山地所山地遥感研究取得系列创新进展

文章来源:成都山地所 发表时间:2017-05-10

  山地是我国自然资源的富集区与涵养地、生物多样性和人文多样性中心,还是自然灾害的多发区和全球变化的指示剂,广袤的山地不仅为遥感研究提供广阔的地理空间,也对实际应用提出了诸多科学和技术挑战。山地崎岖地形及浓缩的环境梯度显著影响了遥感成像过程,定量反演的建模在山区更加“病态”,且产品不确定性难以准确刻画,相关问题已逐渐成为遥感学科的难点、热点和焦点。近期成都山地所李爱农研究员带领团队围绕山地地表遥感辐射传输建模、关键地表参数遥感反演与验证以及山区遥感综合应用开展山地遥感学科建设,并取得系列研究创新进展。

  该团队提出了协同几何特征和特殊地理过程的山地遥感研究新范式,以此为主线,结合国内外最新进展,对山地遥感的相关研究做了阶段总结,新近出版了《山地遥感》专著,书中不仅考虑山地“崎岖地表”的几何形态,还结合山区实际研究对象的特殊时空格局和过程,从地理视角来阐述山地遥感理论、方法及其应用技术,凸显了学科特色。全书共12章,约90万字,内容兼顾了基础性和技术性,是国内外首部围绕山地复杂系统介绍遥感理论与实践的学术著作,为山地遥感学科建设铺垫了新的基石。

  山地遥感作为研究在山地这一特定环境中的遥感基本原理、方法及其应用的科学技术,是遥感科学的重要组成部分,关注其山地特殊性。现阶段,研究内容主要包括:电磁波与山地地表相互作用机理及建模理论,山地遥感影像自动校正与时-空-谱归一化处理方法,山地地表信息遥感反演与同化方法,山地遥感尺度效应与算法/产品验证,山地遥感信息综合应用等。 

  近期,相关研究成果发表在Remote Sensing of Environment、IEEE Transactions on Geoscience and Remote Sensing、Agricultural and Forest Meteorology等领域国际TOP期刊上。
