Paper title：柴达木盆地灌丛沙丘发育过程植被群落演化特征 Paper abstract： 柴达木盆地是我国风沙活动强烈的地区，广泛发育了灌丛沙丘、新月形沙丘、线型沙丘等风积地貌。在沙漠绿洲过渡带广泛分布的灌丛沙丘是群落演替过程中植被与环境共同作用的结果，其形成和演化一定程度上反应了风蚀与沙漠化的程度。本文以柴达木盆地灌丛沙丘植被群落为研究对象，基于文献研究法、实地考察、影像分析等方法从整体上对柴达木盆地灌丛沙丘进行分析，结果表明：（1）柴达木盆地灌丛沙丘分布面积为约为4000平方公里，占盆地总面积的25%左右，主要分布在柴达木盆地西部、中部盐湖区和东南缘；（2）他们分别是：小灶火和大柴旦以西地区灌丛沙丘，平均高度为8 m，沙丘平均体积200 m3，面积占比为23.93%；小灶火和大柴旦东南至德令哈和都兰地区灌丛沙丘，平均高度3 m，沙丘平均体积25 m3，面积占比为37.19%;德令哈和都兰以东南地区灌丛沙丘，平均高度为2m，沙丘平均体积5m3，面积占比为45%（3）柴达木盆地西部灌丛沙丘处于增长阶段，中部盐湖区灌丛沙丘处于稳定阶段，东南缘灌丛沙丘处于衰亡阶段；以期提供一种全新的角度来研究柴达木盆地灌丛沙丘植被群落特征。 Paper type： Tutor 南维鸽

论文题目：Inverted channels and buried channels in the Qaidam Basin, NW China: Insight from remote sensing and numerical simulation 论文摘要：Fluvial channels are extensively identified on the Earth and other terrestrial planets. Two different types of fluvial channels are found in the Qaidam Basin, NW China. Different channels are indicators of different paleo-environments with the complex fluvial and climate history. The buried channel is formed by aeolian deposition process. The inverted channel is caused by differential wind erosion. In this paper, first we propose a workflow to detect the two channels using Sentinel-1 Synthetic Aperture Radar (SAR) datasets and multi-source datasets on Google Earth Engine, then we propose a numerical model to simulate the evolution of the inverted channel. Due to the different backscattering coefficient of the ground surface materials, we set a threshold of the backscattering coefficient as -18.5 dB to distinguish the two channel and surrounding features. Canny edge detection is used to delineate the inverted channels and buried channels. Based on the distribution and morphological characteristics of the two channels and previous studies on sediment chronology in the Qaidam Basin, we propose the evolution process of the channels and climate change since the Holocene. The inverted channel might form during the hyper-arid period of the early Holocene since 12.6±0.8 ka. The buried channel is formed during the period of the sand accumulation since 4-3 ka. 论文类型：期刊论文 导师姓名：陈宁华
