Abstract The second Chinese glacier inventory was compiled based on 218 Landsat TM/ETM + scenes acquired mainly during 2006–10. widely used band ratio segmentation method applied as the first step in delineating outlines, and then intensive manual improvements were performed. Shuttle Radar Topography Mission digital elevation model to derive altitudinal attributes of glaciers. boundaries some glaciers measured by real-time kinematic differential GPS or digitized from high-resolution images...
The Gorkha earthquake (magnitude 7.8) on 25 April 2015 and later aftershocks struck South Asia, killing ~9000 people damaging a large region. Supported by campaign of responsive satellite data acquisitions over the disaster zone, our team undertook image survey earthquakes' induced geohazards in Nepal China an assessment geomorphic, tectonic, lithologic controls quake-induced landslides. Timely analysis communication aided response recovery informed decision-makers. We mapped 4312 coseismic...
An analysis of the spatiotemporal evolution ecological quality and its driving factors in Lanxi urban agglomeration is important for ensuring environmental protection high-quality, sustainable development region. We used moderate resolution imaging spectroradiometer (MODIS) remote sensing images to construct a index (RSEI) using principal component (PCA) reflect agglomeration. The spatial temporal characteristics future changes RSEI study area from 2000 2020 were explored Sen Mann–Kendall...
Abstract The Tibetan Plateau interior area (TPIA), often termed the Qangtang Plateau, is distinguished by many dome-like mountains higher than 6000 ma.s.l. These provide favourable conditions for development of ice caps and glaciers extreme continental/subpolar type. According to historical topographic maps (1959–80) recent Landsat images (2004–11), continuous retreat was observed glacierized part this decreased 9.5% (0.27% a –1 ) with respect total glacier 8036.4 km 2 in 1970s. Glaciers...
Abstract Glacial lake outburst flood hazards in the Himalayan region have received considerable attention recent years. Accurate volume estimation for glacial lakes is important calculating peak discharge and simulating evolution. Longbasaba lake, a potentially dangerous moraine-dammed located on north side of Himalaya. Its depth was surveyed using SyQwest Hydrobox™ high-resolution echo sounder, 6916 measurements were collected September 2009. The maximum average depths 102 ± 2 48 m,...
Abstract. Multi-temporal glacier inventories provide key information about the glaciers, their characteristics, and changes are inevitable for modelling investigating geodetic mass changes. However, to date, no consistent multi-temporal inventory whole of Karakoram exists, negatively affecting monitoring spatio-temporal variations in glaciers' geometric parameters related applications. We used a semi-automatic method combining automatic segmentation manual correction produced (KGI) compiled...
To assess changes in glacial lakes the Chinese Himalaya, 2 inventory phases were conducted on basis of 278 aerial survey topography maps from 1970s and 38 Advanced Spaceborne Thermal Emission Reflection Radiometer (ASTER) images 2000s. In past 30 years, number has decreased, 1750 to 1680 (a decrease 4.0%), whereas average area expanded 166.48 215.28 km2 (an increase 29.7%). Between 3400 6000 m, lake areas at rates 2–84% almost all 100-m elevation bands, dominant expansion different...
The southeastern Tibetan Plateau, where monsoonal temperate glaciers are most developed, has a huge number of glacial lakes. Based on Landsat Operational Land Imager (OLI) images, 192 lakes with total area 45.73 ± 6.18 km2 in 2016 were delineated the Yi’ong Zangbo River Basin. Glacial areas less than 0.1 accounted for 81.77% number, and located above 4500 m elevation comprised 83.33%. Dramatic glacier melting caused by climate warming occurred, resulting formation expansion increase...
Since the 1980s, with rapid economic development and increased attention given to ecological protection, China has launched a series of ecological-restoration programs restore local environment through afforestation natural forest protection. The evaluation vegetation restoration is an important part evaluating effectiveness restoration. Loess Plateau area where problems are concentrated, it key construction in China. This paper takes as research area, using remote sensing geographic...
Abstract. The existence of glacial lakes in the southeastern Tibetan Plateau (SETP) is a potential hazard to downstream regions, as outburst such has result disastrous lake floods (GLOFs). In present study, we conducted comprehensive investigation Bienong Co, moraine-dammed SETP. First, basin morphology was determined, and volume estimated, showing that maximum depth ∼181 m ∼102.3×106 m3. These scenarios included possibility GLOFs being triggered by ice avalanches (Scenarios A1–3) from...
Glacier surges, a primary factor contributing to various glacial hazards, has long captivated the attention of global glaciological community. This study delves into dynamics Kyagar surging and associated drainage features its Ice-dammed lake, employing high temporal resolution optical imagery. Our findings indicate that surge on began in late spring early summer 2014 concluded during 2016. resulted transfer 0.321 ± 0.012 km3 glacier mass from reservoir zone receiving zone, leading formation...
Lake ice, one of the most direct lake physical characteristics affected by climate change, can reflect small-scale environmental changes caused atmosphere and hydrology, as well large-scale such global warming. This study uses National Oceanic Atmospheric Administration, Advanced Very High Resolution Radiometer (NOAA AVHRR), MOD09GQ surface reflectance products, Landsat Tier 1 which comprehensively used RS GIS technology to ice phenology (LIP) in Qinghai Lake. Over past 38 years, freeze-up...
The advancing of glaciers is a manifestation dynamic glacial instability. Glaciers in the Tien Shan region, especially Central Shan, show instability, and have been recently detected. In this study, we used Landsat TM/ETM+/OLI remote sensing images to identify region from 1990 2019 found that 48 advanced. Among them, thirty-four exhibited terminal advances, 14 experienced advances on tributary or trunk. Ten experiencing identified as surging glaciers. These are distributed western part Halik...
With climate warming and intensification of human activities, the eco-environmental problems lakes in middle high latitudes become increasingly prominent. Qinghai Lake, located northeastern Tibetan Plateau, is largest inland saltwater lake China. Recently, problem Cladophora blooms has been widely concerning. In this study, area floating (hereafter FCBs) Lake from 1986 to 2021 was extracted using Floating Algal Index (FAI) method based on Landsat TM/ETM+/OLI Sentinel-2 MSI images, then...
Abstract Third Pole natural cascade alpine lakes (NCALs) are exceptionally sensitive to climate change, yet the underlying cryosphere-hydrological processes and associated societal impacts largely unknown. Here, with a state-of-the-art cryosphere-hydrology-lake-dam model, we quantified notable high-mountain Hoh-Xil NCALs basin (including Lakes Zonag, Kusai, Hedin Noel, Yanhu, from upstream downstream) formed by Lake Zonag outburst in September 2011. We demonstrate that long-term increased...
As an essential data-driven model, machine learning can simulate runoff based on meteorological data at the watershed level. It has been widely used in simulation of hydrological runoff. Considering impact snow cover high-altitude mountainous areas, remote sensing and atmospheric reanalysis data, this paper we established a model with random forest ANN (artificial neural network) for Xiying River Basin western Qilian region The verification measured showed that NSE (Nash–Sutcliffe...
Deep eutectic solvents (DESs), a new class of green solvents, have emerged as promising candidates for electrolytes due to their exceptional electrochemical stability. However, the DES always exhibits unacceptable polarization cells its high viscosity and low ionic conductivity, which limit practical application in batteries. In this work, cell is effectively reduced level comparable that pure aqueous by increasing entropy via disorder‐making strategy solvation structure. Theoretically,...
