Abstract: Sedimentary basin and orogenic belt are two important components of continental structure with internal genetic links. The study of the basin-mountain coupling can reconstruct and restore the coupling relationships between the deep lithosphere process, near-surface structure and climate change over time. The Jianghan-Dongting Basin locates in the middle reaches of the Yangtze River, presenting a clear basin and mountain boundary with the Qinling-Dabie Shan to the north, the Mufu Shan to the southeast, the Wuling Shan to the southwest, and the E'xi Mountain to the west, respectively.
The Meso-Cenozoic Jianghan-Dongting Basin was affected by the subduction and collision of the Pacific plate and the Indian Ocean plate on the Eurasian continent, resulting in multiple tectonic evolution processes. There are some big rivers pouring into the Jianghan-Dongting Basin, such as the Yangtze River, Hanjiang River, Ba River, Xiangjiang River, and Yuanjiang River, etc. to serve as the material transport belts linking between the orogenic belt denudation and basin deposition. Therefore, the Jianghan-Dongting Basin has become a multi-source sedimentary basin, which makes it a natural laboratory to explore the geological processes from source to sink. Because the low-temperature thermochronology(e.g. fission-track and(U-Th)/He)can record the recent uplift time of mountains, they are widely used on the bedrock samples and the detrital synorogenic sediments in basins to constrain the surface uplift time of the orogenic belt. Hence, in the first parts of the paper we summarize and sort out the research results of basin-mountain coupling process in the Jianghan-Dongting Basin, evaluate the research results, identify the existing problems, and propose new research directions. After that, we introduce the applications of low-temperature thermochronology on the bedrock within the orogenic belt, basin and river sediments, combined with the actual situation of Jianghan-Dongting Basin, and put forward a new research breakthrough point. It is found that the Jianghan-Dongting Basin is very suitable for the study of low-temperature thermalchronology on detrital minerals. However, it should combine the low-temperature thermochronology results of both orogenic belt and river sediments with the provenance analysis on the same target minerals, building the connection between the exhumation and provenance information on the orogenic belt, thus providing the detailed evolution of mountain-basin coupling process.

摘要： 沉积盆地与造山带是大陆构造的2个重要的组成单元，具内在成因联系。对其耦合关系进行研究，可以恢复和重建岩石圈深部运动过程，了解近地表构造与气候之间的相互作用。江汉和洞庭盆地位于长江中游，与周缘造山带具有清晰的盆山边界，盆内河流水系十分发育，是一个多物源沉积盆地，是探讨从山（源）到盆（汇）沉积过程的天然实验室。文中对江汉盆地盆山耦合的研究结果进行了总结和梳理，介绍了造山带基岩、盆地和河流沉积物低温热年代学的应用方法，提出了新的研究切入点，建议今后在江汉和洞庭盆地开展盆山耦合研究时，将造山带基岩和河流碎屑矿物低温热年代学结果相结合，同时开展同一目标矿物的物源示踪研究，综合分析造山带隆升信息与物源信息，并与周缘构造和沉积学研究结果相互检验，可得到详细的盆山耦合演化过程。
