Spatial Variations in Methane Content and Their Main Controlling Factors of the Deep‐Buried Coalbed in the Nalinhe–Hengshan Area, Ordos Basin

Energy Science &Engineering, Volume 14, Issue 7, Page 3422-3433, July 2026.
Ash yield is the primary geological factor controlling the spatial variations in the total gas content of the deep‐buried coalbed methane in the Nalinhe‐Hengshan area, Ordos Basin. However, porosity dominates the differential enrichment of the free gas content of the deep‐buried coalbed methane in the Nalinhe‐Hengshan area, Ordos Basin.

Estimating the Geomagnetically Induced Currents in the 1,000 kV Power Grid Over North China During the May 2024 Geomagnetic Storm: Accounting for Anisotropic Earth Conductivity

Space Weather, Volume 24, Issue 7, July 2026.
Abstract Geomagnetically induced currents (GICs) pose a significant threat to the safe and stable operation of power systems, making accurate risk assessment under extreme geomagnetic storm conditions essential. This study focuses on the mid‐latitude North China power grid and estimates substation GICs in the 1,000 kV network during the geomagnetic ...

A Genomic Catalog of Migratory Microbiomes from Wild Birds across China's Habitats

Advanced Science, Volume 13, Issue 26, 8 May 2026.
ABSTRACT Migratory birds play an important role in the spread of antimicrobial resistance (AMR); however, gaps in surveillance data from vital regions along migratory flyways across China limit the detection of emergent threats. Here, we assembled 340 metagenomes from 52 bird species covering 11 provincial administrative districts in China, presenting ...

Spatial Distribution and Conservation Prioritization of Medicinal Gymnosperms in China Using an Optimal Set‐Cover Approach

Ecology and Evolution, Volume 16, Issue 5, May 2026.
The study identified 41 priority conservation grids and 8 critical conservation gaps not covered by national reserves for medicinal gymnosperms. We proposed a practical, multi‐dimensional framework for their conservation. ABSTRACT To elucidate the geographical distribution patterns and hotspots of medicinal gymnosperms in China, providing a scientific ...

Machine Learning‐Driven Classification and Production Capacity Prediction of Tight Sandstone Reservoirs: A Case Study of the Taiyuan Formation, Ordos Basin

Energy Science &Engineering, Volume 14, Issue 5, Page 2514-2538, May 2026.
On the basis of core and log data, a Bayesian‐Optimized Random Forest model achieved 92.76% accuracy in classifying tight sandstone reservoirs. A gray relational analysis‐derived evaluation index shows > 80% consistency with actual gas zones. ABSTRACT Tight sandstone gas (TSG), an unconventional oil–gas resource, has heterogeneous reservoirs ...
