Organic Carbon Storage and Spatial Distribution of Forest Soil in Jiangxi

Abstract:

Organic carbon of forest ecosystems is an essential part of the global organic carbon, which plays a dominate role in forest soil organic carbon research. It was estimated that the forest soil organic carbon density, carbon storage and its abundance index of 11 cities in Jiangxi province according to soil survey data for the second time and forest resources survey data in Jiangxi province during 11th five-year plan. Results showed that organic carbon storage of forest soil in 0-20cm and 0-100cm in Jiangxi province was 401.04×10⁶t and 1025.73×10⁶t respectively, in which yellow soil organic carbon density was higher than that of the red soil. Soil organic carbon storage in forest ecosystems was consistent in 0-20cm and 0-100cm of forest soil in eleven cities of Jiangxi province, among them Ganzhou was the highest in R_a20 while Yichun was the lowest one. In addition, it was inconsistent in the abundance index trend of forest soil organic carbon storages, Shangrao was the highest in R_a20, Yichun was the highest in R_a100, while Nanchang was the lowest one both in R_a20 and R_a100. It was the inverse relationship between total GDP and forest soil organic carbon storage..
