| 摘 要： | 分析夏玉米农学参数、红边参数以及两者之间的相关性,结果表明:可利用红边位置(REP)来反演叶片绿度值(SPAD),利用归一化的吸收深度(ND672)、吸收特征面积(Area672)和红边宽度(Lwidth)来分别反演叶绿素a、叶绿素b、叶绿素a+b以及叶绿素a/b含量;利用一阶微分光谱最大值(FD_Max)和Area672来反演类胡萝卜素含量和类胡萝卜素含量/叶绿素a含量.从而,构建了以红边参数为自变量的农学参数的反演模型,为生产上利用遥感技术大区域,无破坏、实时快速地监测夏玉米的生长状况以及进行营养诊断提供了重要的技术依据. |

| Abstract: | The correlation analysis of agronomy parameters and red edge parameters was present.The results indicated: the REP could be used to retrieve SPAD;ND672 for chlorophyll-a;Area672 for chlorophyll-b and chlorophyll-(a b);lwidth for the ratio of chlorophyll-a and chlorophyll-b;FD_Max for carotenoid;Area672 for the ratio of carotenoid and chlorophyll-a.Thereafter,the regression models of retrieving agronomy parameters,based on red edge parameters obtainable from remotely sensing data,were also established,respectively.Red edge parameters could be considered as a sensitive indicator for summer maize nutrition status,they could provide an important technology to promptly monitor crop growth and accurately diagnose nutrition status by non-destruction means on a large scale. |
| Keywords: | summer maize red edge parameter agronomy parameter retrieval model |
