Scenarios of land cover in Eurasia under climate change
FAN Zemeng, BAI Ruyu, and YUE Tianxiang
The method for surface modelling of land cover scenarios (SMLCS) has been improved to simulate the scenarios of land cover in Eurasia. On the basis of the observation monthly climatic data observed from 2127 weather stations in Eurasia during 1981-2010, the climatic scenarios data of RCP26, RCP45 and RCP85 scenarios re

Implications of diurnal variations in land surface temperature to data assimilation using MODIS LST data
FU Shiwen, NIE Suping, LUO Yong, and CHEN Xin
Based on the Beijing Climate Center’s land surface model BCC_AVIM (Beijing Climate Center Atmosphere-Vegetation Interaction Model), the ensemble Kalman filter (EnKF) algorithm has been used to perform an assimilation experiment on the Moderate Resolution Imaging Spectroradiometer (MODIS) land surface temperature (LST)

Spatiotemporal variations of aridity index over the Belt and Road region under the 1.5℃ and 2.0℃ warming scenarios
ZHOU Jian, JIANG Tong, Su Buda, WANG Yanjun, TAO Hui, QIN Jiancheng, and ZHAI Jianqing
Aridity index reflects the exchanges of energy and water between the land surface and the atmosphere, and its variation can be used to forecast drought and flood patterns, which makes it of great significance for agricultural production. The ratio of potential evapotranspiration and precipitation is applied to analyse

Evaluation of Tropical Rainfall Measuring Mission (TRMM) satellite precipitation products for drought monitoring over the middle and lower reaches of the Yangtze River Basin, China
CHEN Shaodan, ZHANG Liping, ZHANG Yanjun, GUO Mengyao, and LIU Xin
Drought is one of the most frequent and widespread natural disasters and has tremendous agricultural, ecological, societal, and economic impacts. Among the many drought indices, the standardized precipitation index (SPI) based on monthly precipitation data is simple to calculate and has multiscale characteristics. To e

Population, urbanization and economic scenarios over the Belt and Road region under the Shared Socioeconomic Pathways
JING Cheng, TAO Hui, JIANG Tong, WANG Yanjun, ZHAI Jianqing, CAO Lige, and SU Buda
The countries throughout the Belt and Road region account for more than 60% of the world’s population and half of the global economy. Future changes in this area will have significant influences on the global economic growth, industrial structure and resource allocation. In this study, the proportion of the urban popul

Impacts of climate change and LULC change on runoff in the Jinsha River Basin
CHEN Qihui, CHEN Hua, ZHANG Jun, HOU Yukun, SHEN Mingxi, CHEN Jie, and XU Chongyu
The climate change and Land Use/Land Cover (LULC) change both have an important impact on the rainfall-runoff processes. How to quantitatively distinguish and predict the impacts of the above two factors has been a hot spot and frontier issue in the field of hydrology and water resources. In this research, the SWAT (So

Correspondence between the large volcanic eruptions and ENSO events over AD 1525–2000
FANG Xiuqi, ZHENG Xue, and ZHANG Xing
ENSO is an interannual mode which may be affected by external forcing, such as volcanic eruptions. Based on the reconstructed volcanic eruptions chronology and ENSO sequences, both 195 large volcanic eruptions (VEI≥4) and 398 ENSO (El Ni?o and La Ni?a) events were extracted from 1525 to 2000. An analysis of the corresp

Multi-scale temperature variations and their regional differences in China during the Medieval Climate Anomaly
HAO Zhixin, WU Maowei, LIU Yang, ZHANG Xuezhen, and ZHENG Jingyun
The Medieval Climate Anomaly (MCA, AD950-1250) is the most recent warm period lasting for several hundred years and is regarded as a reference scenario when studying the impact of and adaptation to global and regional warming. In this study, we investigated the characteristics of temperature variations on decadal-cente

Glacial changes in the Gangdisê Mountains from 1970 to 2016
LIU Juan, YAO Xiaojun, LIU Shiyin, GUO Wanqin, and XU Junli
Based on the revised First Chinese Glacier Inventory (FCGI), the Second Chinese Glacier Inventory (SCGI) and Landsat OLI images for 2015-2016, we analyzed the spatial-temporal variation characteristics of glaciers in the Gangdisê Mountains from 1970 to 2016. The results showed that there were 3953 glaciers with a

Alternate erosion and deposition in the Yangtze Estuary and the future change
ZHU Boyuan, LI Yitian, YUE Yao, YANG Yunping, LIANG Enhang, ZHANG Chuncai, and BORTHWICK Alistair G. L.
The morphological changing trend of the Yangtze Estuary, the largest estuary of Asia, has become a focus of research in recent years. Based on a long series of topographic data from 1950 to 2015, this paper studied the erosion-deposition pattern of the entire Yangtze Estuary. An alternation between erosion and depositi

Impacts of climate change and agricultural activities on water quality in the Lower Kaidu River Basin, China
BA Wulong, DU Pengfei, LIU Tie, BAO Anming, CHEN Xi, LIU Jiao, and QIN Chengxin
In the context of climate change and over-exploitation of water resources, water shortage and water pollution in arid regions have become major constraints to local sustainable development. In this study, we established a Soil and Water Assessment Tool (SWAT) model for simulating non-point source (NPS) pollution in the
