Characteristics and Mechanism Analysis of Impacts of Different Land Management Types on Soil Carbon Sequestration

Abstract

As an important means to effectively optimize land use, land remediation projects need to be systematically analyzed for their qualitative and quantitative impacts on soil carbon retention. In this study, three types of land remediation project areas, namely sandy land, saline-alkali land, and abandoned residential land in Shaanxi Province, were selected as research objects, and the impact of land remediation years on soil carbon retention capacity was analyzed. The results of this study indicate that due to differences in basic soil properties and engineering implementation technologies, different types of land remediation have different effects on soil carbon retention characteristics. Aeolian sandy land, abandoned homesteads, and saline-alkali land remediation have certain effects on soil carbon retention.
