1利用图谱特征解析和反演作物叶绿素密度显示文摘地面成像光谱仪可对作物个体及群体信息进行'图谱'同步解析,因此在农业定量化研究中具有巨大的应用潜力。利用可见-近红外成像光谱仪采集不同生育期玉米和大豆的冠层'图谱'数据,在逐步提取影像中光照土壤、阴影土壤、光照植被、阴影植被四种组分光谱的基础上,通过选取的敏感波段构建光谱植被指数和叶绿素密度进行波段自相关分析,探讨各个分量对作物叶绿素密度反演的影响。研究发现:当植被与土壤混合存在时,对叶绿素密度敏感的波段基本在红光与近红外波段;当植被光谱提纯后(剔除土壤光谱),对叶绿素密度敏感的波段范围增大,表现在蓝、绿波段;当阴影叶片光谱剔除后,对叶绿素密度敏感的波段表现为可见光波段增加,近红外波段减少,红边波段决定系数最高。上述变化特征在不同作物中有相同的趋势,为探索地面成像光谱仪'图谱'协同反演作物生化参数进行了有意义的探索。张东彦 刘良云 黄文江 Cobum Craig 梁栋 2013红外与激光工程2013,42,7:7
