Abstract:In order to revealing the influence of acid rain stress in succession species, the hyperspectral traits of three seedlings of Pinus massoniana、Schima superba and Cyclobalanopsis glauca were measured during two years. There were three acid rain stress treatments, include pH5.6、pH4.0 and pH2.5. The hyperspectral information is helpful to reveal the relationship between chlorophyll concentration and spectral reflectance in succession species under acid rain influence. The results indicated (1) Chlorophyll concentration of Pinus massoniana seedling in earlier succession stage showed the increased trend with the increasing of the simulated acid rain density, however the seedling of Schima superba and Cyclobalanopsis glauca, which are in middle and late succession stages showed the Chlorophyll concentration are decreased; (2) Along with the test period, the peak wavelength of red edge for the seedling of Pinus massoniana shifted to longer wavelengths but while Schima superba and Cyclobalanopsis glauca shifted to shorter wavelengths; (3) It may promote the seedling of Pinus massoniana growth and impacted the seedling of Schima superba and Cyclobalanopsis glauca growth with the high density and longer period acid rain stress.
