中文摘要：

利用光谱指数和回归分析等方法进行叶绿素含量的反演，比较了归一化植被指数、比值植被指数、叶绿素吸收指数、三角植被指数和叶绿素指数反演叶绿素能力的差异，分析了光谱宽度对叶绿素指数反演叶绿素含量的影响，实现了森林叶片叶绿素含量的定量化反演。

英文摘要：

Spectral indices and regression analysis methods were used to retrieve foliar Chlorophyll concentration. Both of which were based on the spectra and chlorophyll variables of six main tree species in huazhong agriculture university. The ability of normal difference vegetation indice,simple ratio indice, Chlorophyll absortitaion indice, triangular vegetation indice and chlorophyll indice in retrieve chlorophyll concentration were comparied. Then the band width of chlorophyll indice on retrieve precision was discussed.
