摘要

Spatio-temporal variability of Gross Primary Productivity (GPP) remains a challenge despite its importance in the global carbon budget. In this paper, we have attempted to model the Gross Primary Productivity of Indian mangroves with the aid of in situ measurements of biophysical and biochemical parameters using SCOPE model and the results are compared with the GPP outputs derived Vegetation Photosynthesis Model (VPM). Soil Canopy Observation, Photochemistry and Energy fluxes (SCOPE) model is used for simulation of GPP, using in-situ biochemical measurements of chlorophyll content (C b) and maximum carboxylation rate (V ). The simulated values of GPP from the model ranged between 0.0 to 2.6 umol m~2s~' for summer season, 0.0 to 10 umol rrrV for post-monsoon and 0.0 to 6.6 umolm~2 s~(-1) during winter season. Estimated GPP using in-situ measurements and satellite- based Vegetation Photosynthesis Model (VPM) during summer ranges from 0.0 to 6.7 umol m2 s',0.0 to 9.4 umol nv2 s~(-1) in post-monsoon and during winter 0.0 to 6.8 umol m~(-2) s~(-1) from Pichavaram mangrove forest, Tamilnadu. Correlation coefficient between SCOPE GPP and VPM GPP for summer, post-monsoon and winter were 0.88, 0.84 and 0.79 respectively.
