The continuous and intense human activities have greatly changed the structure, path and driving force of the natural water cycle evolution, which conversely influences the water security of human being. With the process of global

Relief degree of land surface (RDLS) is one of the key indicators in the fields of suitability assessment of human settlements (SAHS) as well as resources and environmental carrying capacity (RECC) evaluation at the regional scale

The edge of the Qinghai-Tibet Plateau is characterized by high topographic relief, significant tectonic motion, extreme precipitation, and densely populated active debris flow gullies. It is essential to scientifically categorize

Scientifically assessing the interaction between urbanization and eco-environment in the Tibetan Plateau is critical for optimization of urbanization speed and quality, and for the restoration and improvement of the eco-environmen

The activities of local people and tourists have great effects on the ecological environment on the Qinghai-Tibet Plateau. Different kinds of activities may cause different impacts on ecology and environment. To effectively protec

In the big data era, data of population migration on the Internet has exerted great influence on conducting researches on the patterns of inter-regional population inflows and outflows. This study, based on Tencent's daily migrati

Spatial interaction is a critical basis of understanding human processes on the land surface. Together with spatial dependence, it embodies the uniqueness and relatedness of geographical space, as well as the impact on the embedde

Since the reform and opening-up in 1978, the morphology of urban built-up land (UBL) has been changed significantly due to the rapid socio-economic development in China. Moreover, this change shows an unbalanced variation over spa

Based on the latest hydroclimatic reconstructions in peer-reviewed scientific journals, we summarize the multi-scale pattern on hydroclimatic changes and assess whether or not the variability of the 20th century is unusual in the

The forcing temperature in spring is the main factor that determines the flowering time of woody plants in the Northern Hemisphere. Global warming has reduced the number of chilling days in winter, which probably alters the therma

Drought is one of the most severe natural disasters that have widespread impacts on eco-environment and agriculture. Great efforts have been made on the study of the non-stationarity of hydrometeorological processes, while few rep

The natural river system, which is inherently interconnected, is an essential resource for human and economic society. Beyond water, and the flows of substance (e.g. sediment, contaminant), energy (e.g. streamflow velocity), and i

To understand the non-equilibrium morphological adjustment of a river to environmental changes, it is essential to (i) identify accurately how previous water and sediment conditions have impacted the current morphological adjustme

Under the influence of the changing relationship between the Yellow River and the Huaihe River, the lower reaches of the Huaihe River had gradually drained into the Yangtze River since 1570 AD, and finally became a tributary of th
