Changes of Spectral Reflectance of Pinus densiflora Forest and Relations to Some Factors in Spring at Au Ore Region in Zhaoyuan County,Shandong Province
Abstract:Changes of the characteristics of spectral reflectance of Pinus densiflora forest and their relations to Au, Ag, Cu, Pb contents in pines, chlorophyll contents, degree of haggardis to pines and other ecological factors in spring such as topographic factor and soil composition as well, at Taishang Au ore region in Zhaoyuan County, Shandong Province were analysed. There were differences of spectral reflectance between Au ore and background region in spring. The “blue-shift”in Au mine area was very obvious. The relations among characteristics of spectral reflectance and Au, Ag, Cu, Pb contents in pines were very significant. The characteristics of spectral reflectance were interrelated, to some extent, to chlorophyll contents and degree of injury, but less closely related to some main ecological factors of Pinus densi flora forest.
