ClearExtensive rainfall data analysis: event separation from continuous record, fitting of theoretical distributions, and event-based trend detection
Researchers developed and applied methods for separating discrete rainfall events from continuous records, fitting theoretical probability distributions, and detecting long-term trends in event characteristics, providing tools to better understand how climate change is affecting regional rainfall patterns.
Response of Matching Degree between Precipitation and Maize Water Requirement to Climate Change in China
This study examined how climate change is altering the matching between precipitation timing and maize water requirements across China's monsoon region. Changes in intra-annual precipitation distribution and extreme weather frequency were found to affect crop water availability, with significant implications for food security.
Effect of large topography on atmospheric environment in Sichuan Basin: A climate analysis based on changes in atmospheric visibility
Researchers analyzed 51 years of meteorological station data from the Sichuan-Chongqing region to examine how large topographic features influence the atmospheric environment of the Sichuan Basin, using atmospheric visibility as a proxy for aerosol concentration alongside temperature, humidity, and wind data.
Quantitative Contributions of Climate and Human Activities to Streamflow and Sediment Load in the Xiliugou Basin of China
Researchers analyzed 30 years of data from the Xiliugou Basin in China to quantify how climate change and human activities have affected streamflow and sediment transport. The study found that human activities, particularly land-use changes, were the dominant factor driving decreases in both streamflow and sediment load, with an abrupt shift occurring around 1997.
[Abundances and Morphology Patterns of Microplastics Under Different Land Use Types on the Loess Plateau].
Researchers investigated the abundance and morphological patterns of microplastics across different land use types on the Loess Plateau in China, examining how agriculture, grassland, and other land uses shape microplastic accumulation in soils of this major agricultural production region.
Distribution characteristics of microplastics in soil of Loess Plateau in northwest China and their relationship with land use type
Researchers measured microplastic levels across different land use types on China's Loess Plateau and found an average abundance of nearly 3,000 particles per kilogram of soil. Construction land and cultivated areas had the highest concentrations, while grassland and woodland had lower levels. The study demonstrates that human land use patterns directly influence how much microplastic accumulates in soil across this important agricultural region.
Human Management Decreased Suspended Particle Size in the Loess Plateau Rivers during the 1980s to the 2010s
Researchers analyzed changes in suspended particle size in Loess Plateau rivers from the 1980s to the 2010s, finding that human management interventions including dam construction and reforestation decreased particle size over time. The study documented how anthropogenic river management altered sediment dynamics in one of the world's most erosion-prone landscapes.
Impact of climate change on SARS-CoV-2 epidemic in China
Researchers analyzed the influence of six weather variables on the SARS-CoV-2 epidemic in China, finding that long-term meteorological conditions significantly affect transmission dynamics beyond the short-term effects of physical isolation measures.
Response of microplastic occurrence and migration to heavy rainstorm in agricultural catchment on the Loess plateau
Researchers investigated how heavy rainstorm events affect microplastic occurrence and distribution in an agricultural catchment on the Loess Plateau, finding that rainstorms mobilized microplastics from soil into runoff, with 81.6% of particles smaller than 0.5 mm. Storm-driven transport is identified as an important pathway for moving microplastics from agricultural soils into aquatic systems.
The structure and development of Loess Critical Zone and its soil carbon cycle
Researchers reviewed how carbon moves through the deep layers of the Loess Plateau — a thick deposit of wind-blown sediment in China — finding that soil microbes play an underappreciated role in carbon storage and that current models likely underestimate how much carbon is locked away in these deep soils.
Analysis of hydrochemical characteristics and genesis of water-deficient rivers in China: a case study of the Ciyao River Basin in Shanxi Province
This study analyzed the chemical characteristics and origins of water in the Ciyao River Basin, a water-scarce region in China's Shanxi Province. Researchers collected water samples across wet, normal, and dry seasons and found that the water chemistry was influenced by both natural rock weathering and human activities. The findings provide baseline data for managing water quality in regions where water scarcity makes understanding pollution sources especially critical.
Mitigation of the Ratio of Soil Dissolved Organic Carbon to Available Phosphorus Effectively Improves Crop Productivity under Mulching Measures on the Loess Plateau
This study investigated how different mulching measures affect soil stoichiometric ratios of dissolved organic carbon to available phosphorus in the Loess Plateau, finding that strategic mulching can mitigate nutrient imbalances and support sustainable agriculture in this erosion-prone region.
Review of Managing Soil Organic C Sequestration from Vegetation Restoration on the Loess Plateau
This review examines soil organic carbon sequestration from vegetation restoration on China's Loess Plateau following the Grain-for-Green Project, which has transformed the most severely eroded region into a major ecological restoration success. The review summarizes current knowledge on how different vegetation types and restoration practices affect soil carbon storage.
Effects of Human Activities on Evapotranspiration and Its Components in Arid Areas
Researchers analyzed evapotranspiration changes in arid southern Xinjiang, China from 1982 to 2015, finding that human activities such as land-use conversion significantly altered regional water cycling patterns and the balance between plant transpiration and soil evaporation.

The study provides a framework for monitoring how urbanization affects local ecosystems using remote sensing data.
Optimized Farmland Mulching Improves Rainfed Maize Productivity by Regulating Soil Temperature and Phenology on the Loess Plateau in China
A field experiment on the Loess Plateau found that combining plastic film mulch with straw mulch regulated soil temperature and extended the grain-filling period of rainfed maize, preventing premature senescence and improving yields. The study highlights a trade-off in dryland agriculture: plastic mulch conserves moisture but overheats soil, while novel double-mulching patterns can mitigate the temperature problem while still relying on plastic film.
