“…Therefore, the proper description of surface-groundwater water interaction in CLM4.5 will be the priority work in the future. Recently, Zeng et al [2016] conducted a 60 m simulation with CLM4.5 over five cross sections of Heihe River and studied the eco-hydrological effects of stream-aquifer interaction. Maybe we can learn some knowledge from its extremely high pixel simulation and parameterize it with CLM4.5 for basinscale modeling.…”

Both anthropogenic water regulation and groundwater lateral flow essentially affect groundwater table patterns. Their relationship is close because lateral flow recharges the groundwater depletion cone, which is induced by over‐exploitation. In this study, schemes describing groundwater lateral flow and human water regulation were developed and incorporated into the Community Land Model 4.5. To investigate the effects of human water regulation and groundwater lateral flow on land processes as well as the relationship between the two processes, three simulations using the model were conducted for the years 2003–2013 over the Heihe River Basin in northwestern China. Simulations showed that groundwater lateral flow driven by changes in water heads can essentially change the groundwater table pattern with the deeper water table appearing in the hillslope regions and shallower water table appearing in valley bottom regions and plains. Over the last decade, anthropogenic groundwater exploitation deepened the water table by approximately 2 m in the middle reaches of the Heihe River Basin and rapidly reduced the terrestrial water storage, while irrigation increased soil moisture by approximately 0.1 m3 m−3. The water stored in the mainstream of the Heihe River was also reduced by human surface water withdrawal. The latent heat flux was increased by 30 W m−2 over the irrigated region, with an identical decrease in sensible heat flux. The simulated groundwater lateral flow was shown to effectively recharge the groundwater depletion cone caused by over‐exploitation. The offset rate is higher in plains than mountainous regions.

“…For recycled water, on the one hand, it is good for environmental protection to decrease waste water discharge. On the other hand, recycled water as a new technology will undoubtedly have potential risks for users for various reasons [15][16][17][18]. Therefore, recycled water use is an action that is good for society but harmful to oneself.…”

Abstract:In order to explore the influence mechanism of traditional Chinese culture values on urban residents' acceptance of the reuse of recycled water, this paper selects interdependent self-constructional indicators representing the dependency relation between people as the representative of traditional culture values. In this paper, interdependent self-constructional indicators are introduced based on a technology acceptance model (TAM), in order to establish a hypothesis model. Following this, the writer conducts a study that shows the influence on the acceptance of recycled water through the formation of interdependent self-construction. Finally, the influence mechanism of traditional cultural values on citizens' behavior regarding the reuse of recycled water is determined. To start with, the writer verifies the reliability and validity of data from 584 samples, and then tests the goodness-of-fit between the sample data and the hypothesis model by AMOS21.0 (software). On this basis, the writer analyzes the direct and indirect influence through the hypothesis model and finds that the interdependent self-constructional intensity will accelerate the acceptance process of recycled water technology by positively influencing a change in the residents' attitudes to recycled water. The conclusion shows that traditional Chinese cultural values have a certain influence on urban residents' acceptance of the reuse of recycled water. Meanwhile, the writer clarifies the influence's mechanism.

“…Since the implementation of ecological restoration, the normalized difference vegetation index (NDVI) in the downstream Heihe River basin has significantly increased and the temporal variation in environmental factors, especially water availability (e.g. runoff and groundwater) has been reported as the major driving factor of vegetation recovery Zeng et al, 2016). While large-scale remote sensing data (e.g.…”

“…Every year, approximately 300 billion m 3 of water is delivered using concrete channels, which were built perpendicular to the river to expand the range of the river impact and to deliver water for irrigation. The influence of ecological water conveyance may reach as far as 2000 m from the river (Si et al, 2005;Zeng et al, 2016). While most of vegetation in the downstream Heihe River has been restored (Lü et al, 2015), nearly 20 % of its oasis area covered by desert riparian forests remains degraded despite better downstream water conditions and the rising of groundwater table (Y. .…”

Abstract. Desert riparian forests are the main restored vegetation community in Heihe River basin. They provide critical habitats and a variety of ecosystem services in this arid environment. Since desert riparian forests are also sensitive to disturbance, examining the spatial distribution and temporal variation of these forests and their influencing factors is important to determine the limiting factors of vegetation recovery after long-term restoration. In this study, field experiment and remote sensing data were used to determine the spatial distribution and temporal variation of desert riparian forests and their relationship with the environmental factors.
