Soil organic carbon density and carbon storage of Pu-Ding based on GIS
Based on the soil profile data of the second soil census in Pu-Ding,with the support of GIS,combine with Pu-Ding soil map and land use map,soil bulk data and soil organic matter data,estimated and analyzed soil organic carbon density and the reserves of Pu-Ding.The results show that Pu-Ding carbon storage is 1326.75 * 104 t,the average carbon density is 12.29 kg/m2.The carbon density of the South is lower than the north in the study area,the soil carbon density mainly between 0 to 40 kg/m2,between 10 ～ 20 kg/m2 to achieve the maximum ratio of the area.With the increase of elevation and slope,the distribution of carbon storage in the study area show a similar normal distribution curve,in general,the soil organic carbon is relatively poor in the Pu-Ding.
