Topographic and climatic controls on decadal-scale catchment-basin erosion rates in the northern Chinese Tian Shan

Origin of Late Quaternary Gravel and Drainage Basin Expansion in the Northern Chinese Tian Shan: Insights From Sediment Provenance Analyses

“…Despite of intensive glacial erosion prevailing in the axial part of the northern Chinese Tian Shan during the late Quaternary (Xu et al., 2010; Yi et al., 2004; Zhao et al., 2006) (Figure 2), the topography of the high mountain does not seem to be balanced (Charreau et al., 2017). The rates of erosion at different time scales available now (Charreau et al., 2011; Guan et al., 2022; Guerit et al., 2016; Liu et al., 2011) allow us to discuss the state of landscape evolution in the northern Chinese Tian Shan, although such data are limited. By using hydrological data, the decadal erosion rates of nine drainage basins in the northern Chinese Tian Shan have been estimated to 0.05–0.3 mm/yr with the average rate of ∼0.15 mm/yr (Guan et al., 2022).…”

The estimated erosion rate of 0.05 mm/yr for the whole Urumqi River drainage basin is slightly higher than the rate of ∼0.02 mm/yr at the headwaters of the river (Liu et al., 2011), which has been estimated from the 2‐year river sediment load data measured in the field and the 25‐year daily precipitation data.…”

Prediction of the potential geographical distribution of Cytospora chrysosperma in Xinjiang, China under climate change scenarios

“…Xinjiang is far from the ocean and has a continental arid climate, with large temperature differences between day and night, as well as between summer and winter. The rainfall is generally low, with the annual precipitation in most areas being less than 200 mm (Guan et al, 2022). Overall, there is relatively little forest vegetation in Xinjiang, and the main types of forest vegetation are coniferous forests, scrub forests, broad-leaved evergreen forests, and desert vegetation (Zhang et al, 2021).…”

Impact of Quaternary Glaciations on Denudation Rates in North Pamir—Tian Shan Inferred From Cosmogenic 10Be and Low‐Temperature Thermochronology

“…Studies on the Quaternary denudation in the Pamir (Fuchs et al, 2015;Grin et al, 2018) and the eastern (Chinese) Tian Shan (Charreau et al, 2011(Charreau et al, , 2017(Charreau et al, , 2023Guan et al, 2022;Guerit et al, 2016;Liu et al, 2011;Puchol et al, 2017) shed light on spatial and temporal variations in denudation throughout northern Central Asia (Figure 1), yet denudation within the Kyrgyz part of the Tian Shan, situated between the Pamir and Chinese Tian Shan, has been poorly studied. Available thermochronology data from the Kyrgyz Tian Shan help to constrain exhumation rates averaging over million-year timescales (e.g., Glorie & De Grave, 2016); however, these data are not suitable for evaluating the variability of late-Cenozoic denudation rates following the Plio-Pleistocene onset of Northern Hemisphere glaciations (e.g., Reiners & Brandon, 2006).…”
