Abstract Zhuyeze palaeolake is a terminal lake situated in the arid northern China East Asian monsoon margin. In order to examine Holocene palaeoclimatic change margin, Qingtu Lake section (QTL) from sampled high resolution. Palaeoclimatic proxies such as grain size, carbonate, TOC, C/N and δ 13 C of organic matter, were analyzed; eleven 14 samples six optically stimulated luminescence (OSL) dated provide chronological control. We also investigated geomorphic features shorelines this area....
Groundwater plays a crucial role in the formation of Badain Jaran Desert-Sand Dune Lake System, which has been designated UNESCO World Heritage Site 2024. However, region’s wetland ecosystem is significantly impacted by climate change and human activities. This study utilizes GRACE satellite data situ observation to establish groundwater storage anomaly (GWSA) time series for Desert its surrounding areas (BJDCA) from 2003 2022. The analysis reveals spatiotemporal patterns drought...
Abstract Soil erosion is a global environmental problem, and land‐use changes have significantly altered soil processes. However, processes their major influencing factors vary among different landforms. Dongzhiyuan (DZY), that is, the largest tableland in Loess Plateau (LP), has experienced significant previous decades. little known about impacts of on across landforms DZY tableland. LANDSAT images from 1987, 1997, 2007, 2017 were used to extract information DZY. The decreases farmland...
Significant heterogeneity has been observed among different ecosystem services (ES). Understanding the trade-offs and synergies ES delineating ecological functional zones is crucial for formulating regional management policies that improve human well-being sustainably develop maintain ecosystems. In this study, we used Integrated Valuation of Ecosystem Services Trade-offs (InVEST) Carnegie–Ames–Stanford Approach (CASA) models to evaluate spatial distribution patterns nine (food supply, raw...
Automatic glacier extraction from remote sensing images is the most important approach for large scale monitoring. Commonly used band calculation indices to enhance information are not effective in identifying shadowed glaciers and debris-covered glaciers. In this study, we Kolmogorov–Smirnov test as theoretical basis determined suitable distinguish different land cover classes by comparing inter-sample separability reasonable threshold range ratios of indices. We then constructed a...
This article examines Holocene environmental change in Zhuye Lake the marginal area of Asian monsoon, NW China. environment records were obtained for QTH01 and QTH02 sections Lake. The fluctuations grain size, pollen, total organic carbon content C/N ratios record notable variation. early (11.0 to 7.4 cal. kyr BP) was relatively arid, while vegetation coverage sparse primary productivity low. optimal prevailed during mid‐Holocene (7.4 4.7 BP). Vegetation densest highest mid‐Holocene. During...
Carbon sequestration levels in lakes are often underestimated despite being vital for the comprehensive analysis of CO2 budget and significantly influencing inland arid areas. In this study, eddy covariance (EC) technique was used to measure flux six consecutive years during 2012–2017 a small salt-lake (Yindeer Lake) replenished by groundwater southeastern Badain Jaran Desert, China. The results indicate that: (1) Yindeer Lake net sink CO2, which led estimate that Desert can absorb...
Desert ecosystems possess an astonishing biodiversity and are rich in endangered species. This study investigated characteristics of species diversity soil environmental factors three major deserts China’s Alxa Plateau. The included 183 plant belonging to 109 genera 35 families. highest numbers belonged the Compositae, Gramineae, Chenopodiaceae research area belongs semi-shrub small temperate deserts. Species was low, with Shannon–Wiener index (H′) shrub-herb = shrub > herb tree. Pielou...
Notwithstanding the overall improvement in ecological condition of Qilian Mountains, there are localized occurrences grassland degradation, desertification, and salinization. Moreover, timely accurate acquisition desertification information is a fundamental prerequisite for effective monitoring prevention desertification. Leveraging Google Earth Engine (GEE) platform conjunction with machine learning techniques, this study aims to identify extract spatiotemporal dynamics Mountain National...
