Variations in rare earth elements with environmental factors in lake surface sediments from 17 lakes in western ChinaJournal of Mountain Science - Tập 18 - Trang 1811-1822 - 2021
Ding-ding Du, Liu-qin Chen, Yong-hui Bai, Hai-ping Hu
Numerous lakes in western China are excellent sites for understanding environmental change. However, what dominates rare earth element (REE) variations are still under debate in the lake environmental research. In this study, we selected 28 surface sediment samples from 17 lakes (i.e. large-scale lakes, small water bodies, etc.) in the Qinghai-Tibet Plateau and Xinjiang area. These samples were an...... hiện toàn bộ

This study aims to assess the natural and cultivated plant species in 26 Bedouin farms in Saint Katherine Protectorate (SKP), identify their soil and water characteristics, and assess the suitability of these farms for the cultivation of some wild medicinal plants. The farms were selected to represent wide wadis with deep sand and clay deposits, gorge-like wadis covered with rock fragments of diff...... hiện toàn bộ
Quantitative division of succession and spatial patterns among different stand developmental stages in Changbai MountainsJournal of Mountain Science - Tập 16 - Trang 2063-2078 - 2019
Zhi-wen Gong, Xin-gang Kang, Li Gu
Broadleaf-Korean pine forests exhibit high species richness and distinctive species composition, which are currently becoming more dominant among natural forests in Changbai Mountains of north-eastern China. Understanding the ecological process of restored vegetation is quite important for ecosystem reconstruction. Distinguishing stand development stages and analyzing the dynamic spatial patterns ...... hiện toàn bộ
Relationship between the productivity of Pinus brutia Ten. and site characters, the Taurus Mountains, TurkeyJournal of Mountain Science - Tập 19 - Trang 662-672 - 2022
Emre Kuzugüdenlı
Turkish red pine is an important forest tree species because of its role in the ecosystem whose range includes many countries in the eastern Mediterranean basin. In addition, red pine is a preferred forest tree species due to rapid growth, usage in afforestation in arid areas and the production of non-wood forest products such as resin. The aim of the study was to examine the relationship between ...... hiện toàn bộ
Effect of mixture sowing on biomass allocation in the artificially-planted pastures, Southeastern TibetanJournal of Mountain Science - Tập 16 - Trang 54-63 - 2019
Fan Chen, Hao Xia, Xiao-jing Qin
Artificial planting is an important measure to promote the restoration of degraded grassland and protect the ecological environment. The objectives of the current study were to investigate the allocation pattern between aboveground biomass (AGB) and belowground biomass (BGB) in different seeding types of artificially-planted pastures. We explored the variation in biomass and the relationship betwe...... hiện toàn bộ
Frequency–magnitude of landslides affected by the 27–29 November 2017 Tropical Cyclone Cempaka in Pacitan, East JavaJournal of Mountain Science - Tập 17 - Trang 773-786 - 2020

Tropical cyclone (TC) Cempaka which occurred on 27–29 November 2017 has caused floods, landslides, and strong winds in certain areas of Java Island. Pacitan Regency was the most severely affected by TC Cempaka. The landslide frequency–area distribution curve of event inventory i.e. TC Cempaka can help to understand landslide susceptibility, hazard, vulnerability, and risk. Landslides were identifi...... hiện toàn bộ
Continuum and discrete element coupling approach to analyzing seismic responses of a slope covered by depositsJournal of Mountain Science - Tập 7 - Trang 264-275 - 2010
Hua Zhang, Yang Lu
Numerical analyses of earthquake effects on the deformation, stability, and load transfer of a slope covered by deposits are traditionally based on the assumption that the slope is a continuum. It would be problematic, however, to extend these approaches to the simulation of the slide, collapse and disintegration of the deposits under seismic loading. Contrary to this, a discrete element method (D...... hiện toàn bộ
