摘要：During the FOREMMS (5 FP IST) project,performed in selected EU countries,including candidate country – Poland (Niepolomice Forest),the hyperspectral images made by AISA airborne spectrometer (at 13.08.2003) and results of laboratory (spectrophotometry method) measurements of pigments concentration in Scotch Pine (Pinus sylvestris L.) needles,were used. Samples of Scotch Pine needles were collected from common trees,selected and cut on the FOREMMS monitoring plots. Ranges of the selected 32 spectral channels of AISA spectrometer were specially selected to ensure the correspondence with absorption and reflectance characteristics of pigments i.e.: chlorophyll a,b and carotenoids. The study shows usefulness of high–resolution AISA images as a valuable source of data for estimating “pigments indexes” purposes,especially for estimate concentration of chlorophyll in pine needles. Laboratory analyses demonstrated decrease of chlorophyll content in Scotch Pine needles (all three generation of needles) during growth of tree stand. All of chlorophyll indexes calculated from AISA image had decreasing trend along with the age of needles generation. For mSR705 index this regularity was strongest (Pearson’s correlation coefficient = 0.65). As a result of spatial GIS analyses,the digital map representing concentra?tion of chlorophyll in Scotch Pine needles in Niepolomice Forest,was generated.
