Characteristics of CO₂ Flux over a Mangrove Forest of Southern Thailand in Rainy Season

Abstract

An experiment was conducted to find out the characteristics of CO₂ flux in a mangrove forest of Thailand during the rainy season. The relaxed eddy accumulation method was applied to the measurement of the CO₂ flux over the forest. The CO₂ flux increased with solar radiation, and the daytime downward CO₂ flux was -0.5-1.0mg m^-2s^-1 for the global radiation 400-800Wm^-2, which is about the same magnitude as the typical values obtained in other tropical or temperate forests. The soil respiration was an order of magnitude smaller in the mangrove forest compared to other forests.
