Grasslands play a key role in both carbon and water cycles. In semi-arid and
arid grassland areas, the frequency and intensity of droughts are increasing.
However, the influence of a drought on grassland carbon cycling is still
unclear. In this paper, the relationship between drought and grassland carbon
cycling is described from the perspective of drought intensity, frequency,
duration, and timin... hiện toàn bộ
Effects of sub-/super-critical CO2 on the fracture-related mechanical characteristics of bituminous coalFrontiers of Earth Science - Tập 17 - Trang 760-775 - 2023
Zedong Sun, Hongqiang Xie, Gan Feng, Xuanmin Song, Mingbo Chi, Tao Meng, Bole Sun
Injecting carbon dioxide CO2 into a coal seam is an important way to improve
coalbed methane recovery and to store geological carbon. The fracture mechanical
characteristics of bituminous coal determine the propagation and evolution of
cracks, which directly affect CO2 storage in coal seams and the efficiency of
resource recovery. This study applied CO2 adsorption and three-point bending
fracture ... hiện toàn bộ
A review of inexact optimization modeling and its application to integrated water resources managementFrontiers of Earth Science - Tập 9 - Trang 51-64 - 2014
Ran Wang, Yin Li, Qian Tan
Water is crucial in supporting people’s daily life and the continual quest for
socio-economic development. It is also a fundamental resource for ecosystems.
Due to the associated complexities and uncertainties, as well as intensive
competition over limited water resources between human beings and ecosystems,
decision makers are facing increased pressure to respond effectively to various
water-rela... hiện toàn bộ
The capability of Sentinel-2 image and FieldSpec3 for detecting lithium-containing minerals in central IranFrontiers of Earth Science - Tập 16 - Trang 678-695 - 2022

To date, there are very few studies about the spectroscopy of lithium-containing
minerals (LCMs) in the scientific community. The main objective of this study is
to investigate the capability of Sentinel-2 image and FieldSpec3
spectro-radiometer in terms of mapping five important LCMs, including spodumene,
lepidolite, amblygonite, petalite, and eucryptite. Therefore, first the
FieldSpec3 spectro-r... hiện toàn bộ
Geomorphometric relief classification with the k-median method in the Silesian Upland, southern PolandFrontiers of Earth Science - Tập 14 - Trang 152-170 - 2019
Bartłomiej Szypuła, Małgorzata Wieczorek
The aim of this study is geomorphometric relief classification of a temperate
latitude upland area in Central Europe. The Silesian Upland represents
diversified structural relief which contains a fan-shaped configuration of long
thresholds and wide erosion depressions. A 20 m × 20 m digital elevation model
(DEM) provided input data for the analysis. The k-median method was applied to
examine morph... hiện toàn bộ
Metal accumulation in Asiatic clam from the Lower Min River (China) and implications for human healthFrontiers of Earth Science - Tập 13 - Trang 361-370 - 2019
Yue Zeng, Zhongtao Li, Qianfeng Wang, Changcheng Xu, Yunqin Li, Jia Tang
Considering growing concerns regarding polluted estuaries and their adverse
effects on public health, this study aimed to identify concentrations of metal
(Zn, Fe, Cr, Ni, Cd, Mn, As, Cu, and Pb) in Asiatic clams sampled along the
Lower Min River, China. Multivariate methods were used to identify and apportion
pollution sources. Noncarcinogenic and carcinogenic health risk assessments were
perform... hiện toàn bộ
