Changes in soil organic carbon and nitrogen capacities of Salix cheilophila Schneid along a revegetation chronosequence in semi-arid degraded sandy land of the Gonghe Basin, Tibet Plateau [PDF]

Solid Earth, 2014
The Gonghe Basin is a sandified and desertified region of China, but the distribution of soil organic carbon (SOC) and total nitrogen (TN) along the cultivation chronosequence across this ecologically fragile region is not well understood. This study was

Biological soil crust development affects bacterial communities in the Caragana microphylla community in alpine sandy areas

Frontiers in Microbiology, 2023
IntroductionBiological soil crusts (BSCs) constitute a substantial portion of primary production in dryland ecosystems. They successionally mature to deliver a series of ecosystem services. Bacteria, as an important community in BSCs, play critical roles

Numerical Simulations of Hydraulic Fracturing in Carbonate‐Type Hot Dry Rock Reservoirs Based on the Coupled Thermo‐Hydraulic‐Mechanical‐Damage (THMD) Model

Energy Science &Engineering, Volume 13, Issue 12, Page 5821-5834, December 2025.
ABSTRACT Hydraulic fracturing technology is widely used in Enhanced Geothermal System (EGS) projects to induce fractures and enhance the permeability of thermal reservoirs. The hydraulic fracturing process of hot dry rock (HDR) is actually a multiphysics coupling process that couples the heat transfer field, seepage field, stress field, and damage ...

Methods for geothermal resource assessment of hot dry rock: A case study in the Gonghe Basin, China

Energy Exploration & Exploitation, 2022
Hot dry rock (HDR) geothermal resources are renewable energy source. Many of the findings of HDR resource evaluations have been used in energy planning and EGS design. However, to assess the amount of HDR resources in different locations, a consistent classification scheme and evaluation methods are still lacking.

Developments in Permafrost Science and Engineering in Response to Climate Warming in Circumpolar and High Mountain Regions, 2019–2024

Permafrost and Periglacial Processes, Volume 36, Issue 2, Page 167-188, April/June 2025.
ABSTRACT Research in geocryology is currently principally concerned with the effects of climate change on permafrost terrain. The motivations for most of the research are (1) quantification of the anticipated net emissions of CO2 and CH4 from warming and thaw of near‐surface permafrost and (2) mitigation of effects on infrastructure of such warming and
