摘要

从高光谱遥感角度判别冬小麦旱害和蚜虫危害,可进一步提高遥感监测灾害的准确性。在麦长管蚜的自然危害下,通过控制其生育期水分条件形成的不同程度的干旱胁迫,监测了灌浆末期冬小麦冠层反射率对蚜虫危害和干旱胁迫的反应; 并经一阶微分数据变换,筛选出识别蚜虫虫害和干旱胁迫响应最敏感的光谱波段。实验结果表明: 受蚜虫危害和干旱胁迫后,灌浆末期冬小麦在近红外波段的光谱特征变化比在可见光波段的显著,可见光和近红外波段是识别蚜虫危害和干旱胁迫最敏感的谱段。经一阶微分数据变换发现,自然降水处理(灌水量相当于需水量的＜40%)下的冬小麦光谱曲线的"红边"斜率最小; 受蚜虫危害以及灌水量分别相当于需水量的＞70%,60%~70%,50%~60%和40%~50%水分处理下的"红边"斜率依次变大; 受蚜虫危害冬小麦光谱曲线的"红边"位置波长最短(698 nm),其他不同水分处理结果随着干旱胁迫的加重向波长短的方向发生"蓝移"。因此,"红边"参数也可以作为判别冬小麦蚜虫危害和干旱胁迫的重要参数。

Abstract：

The judgment of the drought threat and aphid harm of winter wheat can further improve the accuracy of monitoring disaster types based on hyperspectral remote sensing data. In this paper, the responses of the reflectance of winter wheat canopy to aphid harm(Macrosiphum avenae(Fabricius))and the drought threat were monitored through controlling the different water treatments under the last phase of the wheat existent in the milk. The most sensitive spectral bands for recognizing aphid pest and drought threat of winter wheat were selected through first derivative data transformation. The experimental results show that, under aphid harm and drought threat,the changes of winter wheat's spectral characteristics in near-infrared band are significantly higher than those in visible light band during the last phase of the wheat existent in the milk. And the most sensitive spectral bands identifying aphid harm and drought threat are visible and near-infrared bands. After the first derivative data transformation,it is found that the slope of the red edge is the smallest when the natural precipitation treatment is less than 40%,and the slopes of the red edge of aphid harm become bigger and bigger when the water treatments of the irrigation amount are higher than 70%,60%~70%,50%~60% and 40%~50% of water requirement, respectively. The red edge wavelength of aphid harm is the shortest,and the wavelengths of different water treatments become shorter with the increase of the drought stress. The red edge parameters can therefore serve as the important parameters for recognizing aphid harm and drought threat of winter wheat.
