中文摘要: |
在分析前人对叶绿素含量监测方法不足的基础上,利用TM(Thematic Mapper)遥感影像探讨了估算冬小麦不同生育期叶片叶绿素相对含量的可行性。并基于遥感变量与地面实测叶绿素相对含量的相关关系分析结果,建立了冬小麦在拔节期和孕穗期叶片叶绿素相对含量的遥感定量估算模型,为利用遥感技术进行冬小麦的长势监测提供了依据。 |
英文摘要: |
Based on the analysis of previous methods of monitoring chlorophyll content,this paper discussed the feasibility of estimating chlorophyll relative content in leaves of winter wheat at different stages by using the TM(Thematic Mapper) images.According to the correlativity between remote sensing variables and measured chlorophyll relative content,the mathematical models were established to estimate chlorophyll relative content at heading and booting stages by remote sensing,which laid a foundation for monitoring the growing state of winter wheat by using remote sensing technology. |
