摘要

Data acquired during soil resource inventory of central Western Ghats, India, were supplemented with other available environmental data to estimate/map soil organic carbon (SOC) stock at the regional level. The study area consists of three major physiographic units: low coastal area, Western Ghats escapment, and the southern part of the Deccan Plateau (Peninsular Plateau). For an area (approximately 88 000 km2) stretching between Goa and the Palghat Gap, a model was developed linking SOC stock to the different environmental parameters known to control SOC levels, particularly type of land cover. Forests of different status, presenting varying stages of degradation, still occupy 43 000 km2 in this area. This can explain the higher SOC stock (0.44 Pg) estimated compared to figures published earlier.
