“…Each set of characteristics has a corresponding range of habitability and population densities. In arid (desert) areas, people tend to live at oases or migrate upstream along the river network, driven by drought events exacerbated by severe evaporation and the drying out of downstream reaches (Ling et al, 2013; Xie et al, 2017). In the northeast plains, several water resources and fertile black soil provide suitable agricultural conditions, but the higher latitude and cold temperatures result in lower population density due to insufficient natural heat energy (Gao, 2012).…”

Human civilization prospers along rivers worldwide. Here, we investigated human-river relations by revealing the linkage between water and habitability for human settlements, and socioeconomic and cultural development across China. We found that human-water co-occurrence relationships are self-similar over subbasins for different scales of stream-order in the river networks. According to the earlier complete demographic census conducted during the reign of the Qing Dynasty ( 1776), there has been a general tendency for inhabitants to live close to rivers, characterized by population density associated with habitability cored by water under a near-natural state, which still remains to date (2019) even after long-term population growth and human interventions. Throughout history, we have extended the linkage of human settlements to humanistic attributes with river networks, derived four different modes of human aggregation towards rivers, and elucidated the geographical diversity of river density, population density, cultural prosperity, and clusters of ethnicity, particularly the Western and the Northeast culture established in the arid (desert) areas, the Huaxia culture in the alluvial plains, the Loess/Nomadic/Southwestern Ethnic culture in the plateaus, and the Qi-Lu/Wu-Yue/Linnan culture in coastlands across the whole country. This work is also of significance to understanding long-term human-water relationships at a global scale.

“…OHR (102°50'0"-103°48'0" E, 38°26'45"-39°10'0" E), situated downstream from Shiyang River Basin (SRB) in northwestern China (Fig. 1), belongs to the cross belt of the Chinese Eastern Monsoon Region, Qinghai-Tibetan Alpine Region with dry climate [25]. The precipitation is about 115 mm per year and is mainly concentrated in July to September, while the potential evaporation is about 2,644 mm per year.…”

Arid and semi-arid regions, where precipitation and water resources are scarce and the ecosystem is bitterly frail and very sensitive to anthropogenic interference, constitute approximately 41% of the total global land area [1-3]. Besides, about 44.46% of arid and semi-arid regions have seen rising temperatures and reduced precipitation in the past 100 years [4]. Deserts and oases are the main landscapes in the arid and semi-arid regions, with deserts as the landscape matrix, and oases as the landscape mosaic [5-7]. Oases are the foundation of human activities and economic development, supporting more than 95% of the population in the arid and semi-arid regions of China even though they only occupy less than 5% of the total area [3, 8]. An oasis not only provides valuable fertile soil and living space for human beings in the barren desert, but also adjusts

“…maxim, Peganum harmala, Artemisia arenaria, and Agriophyllum squarrosum are the native vegetation in this region [28]. Wetlands along rivers (or floodplain), were reclaimed for crop productions as early as Han Dynasty (2000 years ago) [29]. Currently, they are agricultural oases with high productivities and well-developed irrigation networks consisted of rivers, reservoirs, canals, and wells.…”

A lot of timeseries satellite products have been well documented in exploring changes in ecosystems. However, algorithms allowing for measuring the directions, magnitudes, and timing of vegetation change, evaluating the major driving factors, and eventually predicting the future trends are still insufficient. A novel framework focusing on addressing this problem was proposed in this study according to the temporal trajectory of Normalized Difference Vegetation Index (NDVI) timeseries of Moderate Resolution Imaging Spectroradiometer (MODIS). It divided the inter-annual changes in vegetation into four patterns: linear, exponential, logarithmic, and logistic. All the three non-linear patterns were differentiated automatically by fitting a logistic function with prolonged NDVI timeseries. Finally, features of vegetation changes including where, when and how, were evaluated by the parameters in the logistic function. Our results showed that 87.39% of vegetation covered areas (maximum mean growing season NDVI in the 17 years not less than 0.2) in the Shiyng River basin experienced significant changes during 2001–2017. The linear pattern, exponential pattern, logarithmic pattern, and logistic pattern accounted for 36.53%, 20.16%, 15.42%, and 15.27%, respectively. Increasing trends were dominant in all the patterns. The spatial distribution in both the patterns and the transition years at which vegetation gains/losses began or ended is of high consistency. The main years of transition for the exponential increasing pattern, the logarithmic increasing pattern, and the logarithmic increasing pattern were 2008–2011, 2003–2004, and 2009–2010, respectively. The period of 2006–2008 was the foremost period that NDVIs started to decline in Liangzhou Oasis and Minqin Oasis where almost all the decreasing patterns were concentrated. Potential disturbances of vegetation gradual changes in the basin are refer to as urbanization, expansion or reduction of agricultural oases, as well as measures in ecological projects, such as greenhouses building, afforestation, grazing prohibition, etc.
