| 摘 要： | 粒度分析是沉积物研究的主要内容,在辨识物源背景、指代沉积环境、推断气候变化等方面具有重要意义。近60年来,随着中国沙漠科学的不断发展,粒度分析在揭示中国主要沙漠的粒度特征、各类沙丘的粒度特征、沙漠化防治和古环境重建等方面得到了广泛运用,并取得了大量研究成果。与此同时,中国沙漠粒度研究也存在试验方法和参数指代意义不够明晰、沉积环境的系统耦合模型缺乏、沉积物研究的时空延展不足等问题。在今后的研究中,应进一步拓展研究的时空范围、明确参数指代意义、构建系统耦合模型,并与其他沉积物指标相结合,实现多角度多尺度多维度的沙漠粒度分析研究,使粒度分析在中国沙漠研究中发挥更加重要的作用。 |

| Abstract: | Grain size analysis is one of the main sediment research contents. It has critical significance and comprehensive application in identifying source background, studying sedimentary environment, and inferring climate change, etc. In the last 60 years with the development of desert science in China, grain size analysis has been widely used in revealing characteristics of grain size of the main desert and various kinds of dunes in China, in the prevention and control of desertification as well as the reconstruction of the ancient environment. Nonetheless, grain size analysis in China has some shortages, for example, the test method need to be improved, and the meaning of the indication parameters is not clear enough. Additionally, the issues such as the lack of system coupling model of sedimentary environment and limited spatiotemporal extension in sediment research should be aroused attention. The future researches should focus on expanding the spatial-temporal range of the particle size study, clearing the significance of the parameters and combining it with other sediment indicators to construct the system coupling model so as to realize multi angle and multi dimension analysis of desert grain size and to make particle size analysis play a more important role in the study of the desert in China. |
