Investigating natural drivers of vegetation coverage variation using MODIS imagery in Qinghai, China
Springer Science and Business Media LLC - Tập 8 - Trang 109-124 - 2015
Lei Zhou, Aifeng Lyu
The climatically sensitive Qinghai province of China has been recognized as a hotspot for studies on the feedbacks of terrestrial ecosystems to global climate change. Thus, investigating vegetation coverage and its natural drivers in Qinghai is an important focus of ecosystem research. On the basis of Moderate Resolution Imaging Spectroradiometer (MODIS) Enhanced Vegetation Index (EVI) time series...... hiện toàn bộ
Rhizosphere organic phosphorus fractions of Simon poplar and Mongolian pine plantations in a semiarid sandy land of northeastern China
Springer Science and Business Media LLC - Tập 7 - Trang 475-480 - 2015
Qiong Zhao, Hongquan Wang, Zhanyuan Yu, Dehui Zeng
The aim of this study was to investigate the role of rhizosphere organic phosphorus (P) in soil P supply in semiarid forests and the effects of tree species on rihizosphere organic P. We examined organic P fractions in rhizosphere and bulk soils of mono-specific Simon poplar (Populus simonii) and Mongolian pine (Pinus sylvestris var. mongolica) plantations in a semiarid sandy soil of Horqin Sandy ...... hiện toàn bộ
Climate change impacts on the streamflow of Zarrineh River, Iran
Springer Science and Business Media LLC - Tập 13 - Trang 891-904 - 2021
Farhad Yazdandoost, Sogol Moradian
Zarrineh River is located in the northwest of Iran, providing more than 40% of the total inflow into the Lake Urmia that is one of the largest saltwater lakes on the earth. Lake Urmia is a highly endangered ecosystem on the brink of desiccation. This paper studied the impacts of climate change on the streamflow of Zarrineh River. The streamflow was simulated and projected for the period 1992–2050 ...... hiện toàn bộ
Uncertainty assessment of potential evapotranspiration in arid areas, as estimated by the Penman-Monteith method
Springer Science and Business Media LLC - Tập 12 - Trang 166-180 - 2020
Ding Hua, Xingming Hao, Ying Zhang, Jingxiu Qin
The Penman-Monteith (PM) method is the most widely used technique to estimate potential worldwide evapotranspiration. However, current research shows that there may be significant errors in the application of this method in arid areas, although questions remain as to the degree of this estimation error and how different surface conditions may affect the estimation error. To address these issues, w...... hiện toàn bộ
Allometric biomass equations of Larix sibirica in the Altay Mountains, Northwest China
Springer Science and Business Media LLC - Tập 11 - Trang 608-622 - 2019
Yuanyuan Li, Qijing Liu, Shengwang Meng, Guang Zhou
Boreal forests are important carbon sinks and have tremendous potential to mitigate climate change. Aboveground biomass of Siberian larch (Larix sibirica Ledeb.) stands in the Altay Mountains, Northwest China was studied and allometric equations that are related to the biomass of aboveground components using diameter at breast height (DBH) or both DBH and height (H) as independent variables for L....... hiện toàn bộ
Seasonal changes in the water-use strategies of three herbaceous species in a native desert steppe of Ningxia, China
Springer Science and Business Media LLC - - 2021
Haiying Hu, Lin Zhu, Huixia Li, Donghui Xu, Yi Xie
Contribution of groundwater to the formation of sand dunes in the Badain Jaran Desert, China
Springer Science and Business Media LLC - Tập 15 Số 11 - Trang 1340-1354 - 2023
Wang Wang, Jiaqi Chen, Jiansheng Chen, Tao Wang, Lucheng Zhan, Yitong Zhang, Xiaojing Ma
Long-term agricultural activity affects anthropogenic soil on the Chinese Loess Plateau
Springer Science and Business Media LLC - Tập 9 - Trang 678-687 - 2017
Xiaoyun Li, Yiquan Wang, Mark E. Reynolds, Xiaoping Li, Xinwei Lu
Anthropogenic activities largely influence the soil quality of agricultural fields and the composition of soil. Samples of typical anthropogenic Loutu soil in the Guanzhong area of the Loess Plateau, Shaanxi Province, China were collected and measured for soil compaction, bulk density, total organic carbon (TOC), active organic carbon (AOC), and soil enzyme activities to investigate spatial variat...... hiện toàn bộ
Parkland trees on smallholder farms ameliorate soil physical-chemical properties in the semi-arid area of Tigray, Ethiopia
Springer Science and Business Media LLC - Tập 16 - Trang 1-13 - 2024
Selam Ljalem, Emiru Birhane, Kassa Teka, Daniel H. Berhe
Proposed agroforestry options should begin with the species that farmers are most familiar with, which would be the native multipurpose trees that have evolved under smallholder farms and socioeconomic conditions. The African birch (Anogeissus leiocarpa (DC.) Guill. & Perr.) and pink jacaranda (Stereospermum kunthianum Cham.) trees are the dominant species in the agroforestry parkland system in th...... hiện toàn bộ
Integrating water use systems and soil and water conservation measures into a hydrological model of an Iranian Wadi system
Springer Science and Business Media LLC - Tập 12 - Trang 545-560 - 2020
Nariman Mahmoodi, Jens Kiesel, Paul D. Wagner, Nicola Fohrer
Water resources are precious in arid and semi-arid areas such as the Wadis of Iran. To sustainably manage these limited water resources, the residents of the Iranian Wadis have been traditionally using several water use systems (WUSs) which affect natural hydrological processes. In this study, WUSs and soil and water conservation measures (SWCMs) were integrated in a hydrological model of the Hali...... hiện toàn bộ
