Abstract
Revealing the leaf photosynthetic characteristics and biomass distribution of vascular plant species is crucial to deepen our understanding of the ecophysiological background of growth of these plants as well as to estimate the spatial distribution of net primary production along the successional gradients in a high Arctic tundra ecosystem. This paper shows leaf CO2 gas exchange study on the vascular plants from Ny-Alesund, Svalbard, Norway. Spatial distribution of net primary production is also estimated by combining the leaf photosynthetic characteristics and biomass distribution in a foreland of glacier.
