Summary: This study quantitatively analyzed the effects of flooding on the growth and species diversity of riparian forests along the Yarkant River and the Tarim River in northwest China. The results showed that flooding significantly increased indices for the lower reaches of the rivers and led to the appearance of new plant species. Flooding also improved the regeneration capacity and species diversity of desert riparian forests. These findings provide important information for water resource management in arid regions.

Summary: Trunk internal decay is a common issue in Euphrates poplar trees along the Tarim River, with different patterns and spatial distributions in the middle and lower reaches. Water stress plays a significant role in trunk decay, and tree morphology and height also affect the severity of decay.

Summary: This study focused on the distribution of antibiotics in the riparian zone and their potential contamination risks to surface water and groundwater. The results showed that macrolide antibiotics were prevalent in river water and groundwater, with ofloxacin and chlortetracycline having the highest concentrations. The river-groundwater interaction was found to have a certain interception effect on antibiotics, especially near riverbanks. Environmental risks posed by antibiotics were assessed for algae, daphnids, and fish, with only clarithromycin and chlortetracycline presenting a medium risk to algae.

Summary: This study found that the river-groundwater relationship significantly influences the lateral zonation of plant species composition and diversity along regulated rivers. Different types of river-groundwater relationships result in varied plant distributions, with higher diversity within the groundwater fluctuation zone and lower diversity outside of it. Understanding these patterns can provide valuable guidance for designing appropriate water conveyance schemes.

Summary: The study found that groundwater and root trait diversity jointly regulate underground carbon storage in arid inland river basins. Root trait diversity has the largest impact on fine root biomass, with groundwater affecting it primarily through indirect pathways mediated by root trait diversity.

Summary: This paper selects the Tarim River Basin as a case study to analyze the impact of ecological water conveyance on desert riparian vegetation and hydrological elements. It constructs an ecological environment quality evaluation system and comprehensively evaluates the effect of ecological water conveyance on the damaged desert forest ecosystem. The research shows that ecological water conveyance has played a positive role in groundwater recharge and ecological restoration, providing important scientific reference for the protection and restoration of vegetation degradation in arid watersheds.

Summary: This study examines the irreversibility of river floodplains to recover their status, which may be explained by the dynamics of riparian water-tolerant plant roots. The developed model provides a quantitative tool for predicting the impact of changing flow regimes on long-term river floodplain dynamics.

Summary: The desert riparian vegetation zone is important for river evolution and bank stability due to the effect of vegetation roots on the bank and resistance to erosion. A study on the Tarim river examined the impact of six vegetation species on bank stability. Results show that different vegetation roots can reduce toe erosion and influence bank collapse.

Summary: Tree mortality and regeneration play crucial roles in forest dynamics in arid regions. Water scarcity is the primary limiting factor for long-term changes in tree mortality, with canopy gaps promoting tree regeneration to some extent. The survival of seedlings and saplings is influenced by light availability and soil water at a regional scale.

Summary: Desert riparian vegetation plays an important role in ecological water conveyance and biodiversity conservation. This study analyzed the ecological restoration status of the Tarim River from 2015 to 2021 and found that ecological water conveyance has contributed to groundwater recharge and restored desert forest ecosystems. The overall habitat status and ecological environment quality have improved significantly.

Summary: This study defines ecological water rights based on the elasticity and relative importance of ecological water use in different regions of a basin, and proposes a method for allocating these rights. The application of this method in the mainstream watershed of Tarim River in China shows that it can meet the ecological water demand of vegetation in important areas when the overall available ecological water is 77% of the demand. However, the demand in non-important areas must be reduced.

Summary: Estuarine rivers play a crucial role in allowing seawater to travel upstream and salinize adjacent aquifers. However, the mechanism of riparian saltwater intrusion has received less attention compared to saltwater intrusion at the coast. This study collected time series measurements of river and groundwater freshwater head, specific conductance, and hydraulic gradient to investigate the relationships and fluctuations in both systems. The findings suggest that cyclic flow processes drive the alternation of saltwater intrusion and retreat, with the occurrence of negative hydraulic gradient potentially leading to increased groundwater salinization.

Summary: The Root Distribution Model (RDM) is a framework that combines three known analytical models to predict the spatial distribution of tree root system variables under different environmental conditions. The model is physically based and can be easily calibrated with a single tuning parameter, making it adaptable to a variety of situations.
