摘要
胡杨作为塔里木河流域的建群种与生态恢复的指示器,是遏制土地荒漠化和保护群落稳定结构的天然屏障。仅依靠人工调查对荒漠河岸林进行监测已不能满足当下维系塔里木流域生态环境,高光谱遥感成为当下胡杨种群监测识别的重要手段。就沙漠干旱地区胡杨叶片色素高光谱遥感监测的主要研究成果做出了概括,并经过对有关论文内容的总结与数据的梳理,明确了胡杨叶片色素高光谱遥感的科研前沿领域和技术进展动向。以此为基准,整理和分析了胡杨树叶色素高光谱遥感技术的主要方法,以及高光谱处理、波段参数和模型建立等方法的使用。明确了胡杨叶片色素高光谱遥感的发展方向,为胡杨林的有效保护提供参考。
Populus euphratica,as a constructive species and an indicator species for ecological restoration in the Tarim River Basin,has the effect of preventing wind and sand fixation and improving soil.It is a precious forest resource unique to desert areas.Only relying on manual surveys to monitor them can no longer meet the current needs of saving the ecological environment of Tarim.Hyperspectral remote sensing,as a remote sensing technology that can obtain spectral information of surface vegetation,has become an important means for monitoring and identifying Populus euphratica populations.This article reviews the research progress of Populus euphratica pigment hyperspectral remote sensing monitoring and identification.Through the statistics of published literature in this field and the analysis of main institutions,teams and data sources,the research hotspots and trends of Populus euphratica leaf pigment hyperspectral remote sensing monitoring are clarified;On this basis,sort out and analyze the main analysis techniques and methods of Populus euphratica leaf pigment hyperspectral remote sensing,including spectral processing technology,application based on single band and model construction method.It provides a theoretical basis for the future development of Populus euphratica leaf pigment hyperspectral remote sensing and the effective protection of Populus euphratica forest.
