Review of drought impacts on carbon cycling in grassland ecosystems
Frontiers of Earth Science - Tập 14 - Trang 462-478 - 2020
Tianjie Lei, Jie Feng, Cuiying Zheng, Shuguang Li, Yang Wang, Zhitao Wu, Jingxuan Lu, Guangyuan Kan, Changliang Shao, Jinsheng Jia, Hui Cheng
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 coal
Frontiers 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 management
Frontiers 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 Iran
Frontiers of Earth Science - Tập 16 - Trang 678-695 - 2022
Kazem Rangzan, Mostafa Kabolizadeh, Sajad Zareie, Adel Saki, Danya Karimi
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 Poland
Frontiers 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
Assessing spatio-temporal variations of precipitation-use efficiency over Tibetan grasslands using MODIS and in-situ observations
Frontiers of Earth Science - Tập 10 - Trang 784-793 - 2016
Zhengjia Liu, Mei Huang
Clarifying the spatial and temporal variations in precipitation-use efficiency (PUE) is helpful for advancing our knowledge of carbon and water cycles in Tibetan grassland ecosystems. Here we use an integrated remote sensing normalized difference vegetation index (NDVI) and in-situ above-ground net primary production (ANPP) measurements to establish an empirical exponential model to estimate spati... hiện toàn bộ

Metal accumulation in Asiatic clam from the Lower Min River (China) and implications for human health
Frontiers 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
