Aiming at the material source of "wide, gentle" and "narrow and steep" debris flow gully, based on field investigation and indoor rock and soil mechanical parameter test, this study uses indoor model experiment to study the starting mechanism of loose material in gully under different influencing factors. Through data analysis and fitting, the dynamic reserve model of gully provenance is established, which provides reference and scientific basis for the prediction, early warning and treatment engineering design of similar debris flow gully in earthquake area. The main conclusions are as follows: (1) The incipient erosion processes of deposits with different structural types are different: fine-grained soil appears rills at the front edge after the start of runoff at the rear, and gradually develops into pull grooves, which run through to the rear edge; After the runoff of coarse-grained soil starts, the front edge collapses and slides, showing the characteristics of traceability erosion; The upper fine and lower coarse soil first formed grooves at the boundary of soil layer and gradually extended to the rear edge; The upper coarse and lower fine soil first form a rill at the front edge, and the coarse soil in the back layer slides and scrapes the fine soil at the front edge. (2) At the moment of debris flow starting, coarse particles are mainly started in the form of sliding, jumping and rolling, and the starting and migration forms of coarse particles in fine-grained soil are mainly rolling and jumping; In coarse-grained soil, the coarse particles are mainly started by sliding; The confluence of upper fine and lower coarse soil is dominated by rolling and jumping in the early stage, and sliding in the later stage; The coarse particles in the upper coarse and lower fine soil start mainly by sliding. (3) The greater the rainfall intensity, the greater the runoff, and the stronger the undercutting erosion. The erosion curve tends to increase first and then decrease, and the maximum erosion depth generally appears at the place where the slope changes steeply and gently. (4) Based on the indoor simulation test results and fractal dimension theory, the evaluation model of "wide and slow" channel source dynamic reserves is established and verified.

The distribution of disaster points shows that there are fewer disaster points along the north line and in the scientific research county, while there are more disaster points along the south line and in the scientific research county. During the scientific research, wind sand points and mountain erosion points were found and recorded. Especially in the valleys and gullies around the Himalayas, disasters such as landslide and debris flow are easy to occur, while geological disasters are not easy to occur in the Qiangtang plateau area (plateau surface). The photos of disaster points can reflect the disaster characteristics of a region. They are intuitive data for studying local disaster types, and then have basic significance for local disaster types, distribution and disaster prevention and reduction measures.

This data set is derived from the paper: Ma, L. *, Wang, Q. *, Kerr, A.C., Yang, J.H., Xia, x.p., ou, Q., Yang, Z.Y., sun, P., 2017. Paleocene (ca. 62 MA) leucogenes in southern Lhasa, Tibet: products of syn colonial strategic analysis during slab roll back? Journal of petroleum, 58 (11): 2089-2114. This research achievement is supported by the special project "deep process and resource effect of major geological events in Yanshanian period" (2016yfc0600400) of national key R & D Program "exploration and exploitation of deep resources". This achievement is a part of the research achievements of associate researcher Ma Lin, researcher Wang Qiang and their team in petrology and deep dynamics of the Qinghai Tibet Plateau. The team applied petrological and geochemical methods to reconstruct the collision evolution history of the southern margin of the Himalayan Tibetan Plateau orogenic belt. The Paleocene (63-58 MA) garnet two mica granite and biotite granite assemblage were determined by the applicant in Gangdise. It is found that the two types of rocks have the same sr-nd-hf-o isotopic composition, but the major elements show the characteristics of increasing with the increase of Si Al composition and decreasing with the decrease of Mg Fe composition. At the same time, similar mineral composition evolution is found, including the transformation from mg biotite to iron biotite, the continuous composition evolution of medium feldspar Pei feldspar aofeldspar albite, and the increasing composition of garnet core to edge, It is revealed that garnet two mica granite is the product of high differentiation evolution of Cenozoic lower crust melt, which provides petrological evidence for the high differentiation genesis of I-type leucogranite. The study also reveals that the Gangdise syn collisional anatexis is related to the diachronic collision of the Indo subcontinent. The interaction model of continental collision and oceanic subduction also provides reference and Enlightenment for understanding the abnormal thermal phenomena of the crust and lithosphere in the global large convergent orogenic belts.
