Exceptional increases in fluvial sediment fluxes in a warmer and wetter High Mountain Asia

Science, Journal Year: 2021, Volume and Issue: 374(6567), P. 599 - 603

Published: Oct. 28, 2021

Rivers originating in High Mountain Asia are crucial lifelines for one-third of the world’s population. These fragile headwaters now experiencing amplified climate change, glacier melt, and permafrost thaw. Observational data from 28 headwater basins demonstrate substantial increases both annual runoff sediment fluxes across past six decades. The accelerating mid-1990s response to a warmer wetter climate. total flux is projected more than double by 2050 under an extreme change scenario. findings have far-reaching implications region’s hydropower, food, environmental security.

Dual Influence of Climate Change and Anthropogenic Activities on the Spatiotemporal Vegetation Dynamics Over the Qinghai‐Tibetan Plateau From 1981 to 2015

Earth s Future, Journal Year: 2022, Volume and Issue: 10(5)

Published: May 1, 2022

Abstract Climate change and human activities have already caused degradation in a large fraction of vegetation on the Qinghai‐Tibetan Plateau (QTP). Many studies report that climate variability instead overgrazing has been primary cause for large‐scale cover changes QTP, example, Lehnert et al., 2016, https://doi.org/10.1038/srep24367 . However, it remains unclear how (mainly livestock grazing) regulate dynamics under change. This paper takes AVHRR/GIMMS Normalized Difference Vegetation Index (NDVI) as an indicator to analyze growth status zones which highly sensitive The spatiotemporal between 1981 2015 were analyzed. dual effects examined by correlation analyses data from 87 meteorological stations economic statistical QTP. Results show that: (a) central southwestern QTP with high altitudes was improving due warm‐humid trend. An increase temperature reduction harsh frigid at global warming resulted expansions vegetated areas, NDVI showing concordant increase. (b) degraded areas mainly confined northern eastern population densities. In comparison gently changing regimes, anthropogenic such chronic concentration valleys less exerts much stronger pressure vegetation. study indicates pressures are more intensive than impact critical conservation sustainable management

Dynamic Simulation of Land Use/Cover Change and Assessment of Forest Ecosystem Carbon Storage under Climate Change Scenarios in Guangdong Province, China

Remote Sensing, Journal Year: 2022, Volume and Issue: 14(10), P. 2330 - 2330

Published: May 11, 2022

Exploring the spatial distribution of land use/cover change (LUCC) and ecosystem carbon storage under future climate scenarios can provide scientific basis for optimizing resource redistribution formulating policies sustainable socioeconomic development. We proposed a framework that integrates patch-generating use simulation (PLUS) model integrated valuation services tradeoffs (InVEST) to assess spatiotemporal dynamic changes in LUCC Guangdong based on shared pathways representative concentration (SSP-RCP) provided by Coupled Model Intercomparison Project 6 (CMIP6). The results showed patterns were similar SSP126 SSP245 scenarios, but artificial surface expanded more rapidly, increase forest slowed down SPP245 scenario. Conversely, SSP585 scenario, sharply resulted continuous decrease land. Under three population, elevation, temperature, distance water highest contributing driving factors growth cultivated land, grassland, surface, respectively. By 2060, terrestrial ecosystems increased from 240.89 Tg 2020 247.16 243.54 respectively, which 17.65 15.34 Tg, respectively; while it decreased 226.54 due destruction accounted 81.05% total storage. Overall, an important recommendation this study is be controlling population economic growth, balancing urban expansion ecological conservation, as well increasing area.

Ecological security assessment and pattern construction in arid and semi-arid areas: A case study of the Hexi Region, NW China

Ecological Indicators, Journal Year: 2022, Volume and Issue: 138, P. 108797 - 108797

Published: March 25, 2022

Ecological security assessments are used to reflect the regional ecological situation because they can provide a basis for construction of patterns (ESPs). Using land use/land cover (LULC) data, status Hexi Region was analyzed. On this basis, source extracted, resistance surface established, and corridor node were identified, constructed ESP Region. The results show that: 1) During 2000–2015, approximately 70% study area's index values <0.1. ecosystem levels higher in southeast lower northwest. 2) total area sources 6828.75 km2, it is less distributed west; interconnection degree among low; patch fragmentation obvious. 3) A 134 corridors with length 15572.8 44 nodes identified. distributions had spatial consistency mainly concentrated central southern parts Qilian Mountains. method assessment based on LULC data be popularized applied evaluation regions having lack research or difficulty obtaining data. This guiding significance optimization elements improvement ESPs other arid areas.
