ANALYSIS OF CARBON AND NITROGEN STORAGE OF DRY TROPICAL FOREST ECOSYSTEM USING SATELLITE REMOTE SENSING AND GIS TECHNIQUES

摘要

Tropical forests are recognized as rich, diverse and highly productive ecosystems of the world. The present study was carried out to assess Carbon and nutrient storage ofa dry tropical forest ecosystem in Barnawpara Sanctuary, Raipur district of Chhattisgarh through satellite remote sensing techniques and GIS. The total storage of nutrients in vegetation (OS+US+GS) varied from 105.1 to 560.69 kg ha~(-1) in Nitrogen and 7310 to 4836 kg ha~(-1) for Carbon in different forest types. They were highest inDense mixed forest and lowest in Degraded mixed forest. The study also showed that NDV1 and carbon storage was strongly correlated to Shannon Index and species richness thus it indicates that the diversity offorest type play a vital role in carbon accumulation. The study also developed reliable regression model/or the estimation of C & N storage in dry tropical forests by using NDVI and different vegetation indices, which can be derived fromfine resolution satellite data.
