| 英文简介 | Saline soil was regarded as reserve cultivated land resources in China, accounting for 4.88% of the available land area in our country. The development and utilization of salinization land will affect the change of the terrestrial ecosystem carbon cycle. Under the background of reducing greenhouse gas emissions entering the international policy agenda, land use change has become one of the hot issues of global environmental change research. the different of land utilization type would have different influence on migration and transformation process and carbon stock of soil aggregate and aggregate organic carbon,which will affect the entire terrestrial ecosystem carbon cycle. This topic chosen TuMoChuan plain salinization soil as the research object, research on the influence of land use change on soil aggregate stability, Organic carbon composition(light group of organic carbon, particulate organic carbon, active organic carbon, microbial biomass carbon, soluble organic carbon, free particulate organic carbon, occluded particulate organic carbon, mineral associated organic carbon), in order to uncover soil aggregate stability and different composition soil carbon stock respond to land use changes in semiarid plateau plain salinization soil area. improve people's understanding of soil carbon stability mechanism, to provide the basis data for further explore the influence of the land use change on soil carbon library dynamic process and influence mechanism, provide a scientific basis to optimal allocation of salinization land use form, land productivity and carbon sequestration ability in our country as well. |
