| 英文简介 | This project intends to carry through the space analysis of Lop Nor “drought rings”, to reconfirm Lop Nor scope quantitatively, to divide relative periods of Lop Nor drying process, by means of radar detection techniques; By time-space information comprehensive analysis and environment evolution model with the data assimilation method, realizes the space-time representation of Lop Nor drying process. Based on the unique penetrating power of radar remote sensing and field survey, fully investigates the ancient hydrological network in Lop Nor region, to reappear the water system network structure in different periods; By remote sensing interpretation, field survey and dating analysis, extracts the information of river and lake landform and their evolution, to reconstruct Lop Nor change history in geological periods; Extracts climate and environment change information containing in typical plant cones, to reconstruct the modern climate and environment change sequence with high resolution, and to invert the paleo-climate and paleo-environment characteristics. Aiming at the key locations recording climate and environment mutations in Lop Nor drying the process, combined with the regional climate, environment and dating data in the past, carries through the correlation analysis of extreme climate and environment events. By “Attribution analysis of space-time representation and influence factors on Lop Nor drying process”, reveals the process and mechanism of environmental change of arid zones, and provides theoretical support for sustainable development of arid zones. |
