| 英文简介 | Lake in arid land, which plays an incredible role in maintaining of the regional ecosystem balance, is an important part of the arid ecosystem and is highly sensitive to climate change and environment evolution. In the context of climate change, intense human activity leaded lakes to shrink and even dry up, followed by environmental degradation and serious desertification. As a result, frequent dust storms occurred. This project is aimed to understand the mechanism of eolian dust from the playa of Ebinur lake and its diffusion characteristics in the atmosphere boundary layer, three key questions are urgent to be answered, i.e., how do the key parameters that affect the eolian dust change? What is the spatial pattern of key processes that control the dust emission from the playa? And what are the main features of dust spread in the atmosphere? Within the selected Ebinur lake playa, quantitative studies will be implemented through statistical analysis, positioning observations and model simulations to gain the land surface parameters and aerodynamic parameters and their variation, to understand spatial differences of the process that control the dust generation near the surface, and to define the pathways and range of dust suspended in the atmospheric boundary layer. This project will identify the main factors influencing the occurrence of eolian dust, reveal regional differences of eolian dust generation in complex underlying surface thoroughly, and interpret dust release characteristics and its diffusion characteristics scientifically, and increase understanding and awareness of the important dust source in the evolution process of lakes in arid land. Meanwhile, results of this project could provide a reference for tail-end lake area to take effective measures to defense eolian dust, as well as provide a scientific basis for construction and management of ecosystems in the tail-end lake area. |
