摘要

Biosphere-atmosphere exchange of NO, at the Sundarban mangrove forest alongthe northeast coast of the Bay of Bengal, India, showed uptake rates of -0.84 to-1.63 ng N M-2 s-1 during the day and both uptake and emission rates of -0.36 to5.19 ng N M-2 s-1 during the night from September to February. However, during theperiod from March to August, NO, emission ranged between 0.34 and 2.13 ng N m-2 s-1and 0.88 and 3.26 ng N M-2 s-1 in daytime and nighttime, respectively. During thepostmonsoon period, NO, uptake could be attributed to mangrove stomatal activity duringthe day. Mangroves absorbed nitrogen from both the soil and the atmosphere. Seasonaland diurnal variability of NO, and 03 is partly due to plant growth in the postmonsoonperiod. In addition to the NO,-03 photochemical cycle, stomatal uptake of NO, couldalso be an important process for keeping a low-ozone state at the land-ocean boundary ofthe northeast coast of the Bay of Bengal.
