东湖地区几种特征植物绿素的光谱特征

通过测量武汉东湖地区部分特征植物(桃树、槐树、冬青树)光谱数据及叶绿素浓度数据,在消除环境对数据的影响后进行分析,确定这些植物受叶绿素浓度影响较大的特征波段,并发现相同叶绿素浓度下桃树、槐树、冬青树光谱特征的一些差异。对所研究植物的各特征波段进行了多波段处理,建立不同波段反射率比值因子与叶绿素浓度的经验回归模型,分析各模型对叶绿素浓度的反演精度,优择出不同植物各自的最佳经验模型及几种植物共同的最佳经验模型。

Research on the Relation between Chlorophyll Content and the Spectral Characteristics of Some Representative Plants in East Lake Area in Wuhan

The spectral reflectance and chlorophyll content of the three representative plants (peach,Sophora japonica,ilex tree) were measured in East Lake area in Wuhan to reveal the relation between chlorophyll content and spectral characteris- tics of the plants in this study.The results showed that the wavebands influenced by chlorophyll Content of the three plants were identified and the differences of spectral characteristics between peach,Sophora japonica and ilex trees were found when the three plants had the same chlorophyll content.The regression models between reflectance and chlorophyll content were established in various wavebands by multiband technology and the optimal models of three plants were selected based on the precision analysis of the models.
