By analysing the spatiotemporal changes and correlations between precipitation (PRE), soil moisture (SM), vapour pressure deficit (VPD) and normalized difference vegetation index (NDVI) in the Yellow River Basin, we explored the different effects of three water elements on vegetation in different climatic regions. Our findings reveal the following: (1) NDVI and the three water elements report an increasing trend in the Yellow River Basin, with NDVI increasing most significantly. 92.1% of the Yellow River Basin showed an increase in NDVI. (2) Vegetation in the Yellow River Basin was most positively affected by PRE, followed by SM and VPD. PRE mainly affected the natural vegetation on both sides of the boundary between the arid and semi-arid regions and the semi-humid regions. SM mainly affected the natural vegetation in the arid and semi-arid regions, whereas VPD mainly affected the crops in the irrigation areas, and the irrigation areas in arid regions were affected the most.

Riparian tree mortality is increasing in the western United States, where altered streamflows are combining with warming climate. Between 2011 and 2013, one third of an extensive stand of <i>Populus deltoides</i> var. <i>wislizeni</i> (Rio Grande cottonwood) died along the middle Rio Grande on the Pueblo of Santa Ana in New Mexico. Mortality coincided with a severe drought that followed a decade of decreasing streamflow, but it was heterogeneous, with adjacent patches of dead and live trees. The goal of this research was to determine the drivers of mortality to provide insights into future risks of die-off and potential management interventions. We compared tree age, competition, tree-ring widths, sediment particle size and climate influences between live and dead forest patches in a nested plot design. Live and dead trees had similar age, stand density and particle sizes of shallow sediments. Tree-ring widths had the highest correlations with July–September streamflow (1932–2013). All trees had declining ring growth since 1992, coinciding with declining late summer streamflow. An accelerated decline in growth began in 2002, corresponding to recent warmer droughts. Trees that died had lower ring growth 3 years prior to death and in the mid-1900s. Dead trees also had coarser deep sediments 2.4–3.7 m below ground, suggesting that reduced water holding capacity was an important factor for mortality. Water management to increase streamflow during the late summer, especially during times of extended drought, could reduce mortality risk in the face of projected increasingly warm droughts.</p>","PeriodicalId":55169,"journal":{"name":"Ecohydrology","volume":"17 8","pages":""},"PeriodicalIF":2.5,"publicationDate":"2024-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143121238","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This work aims to improve understanding of the response of SWP to varied rainfall pulses, and of the water-use strategies of a widespread C₄ shrub (<i>Haloxylon ammodendron</i>, HA) in arid northwestern China. Rainfall manipulation experiments and field measurements on HA were undertaken to explore the response features of SWP and plant physiological status to pulsed rainfall events of varied magnitudes and durations. The physiological state of HA was evaluated by quantifying critical metrics indicative of plant water-use strategies, including leaf water potential, photosynthetic rate and transpiration rate. The response value of SWP increased with rainfall magnitude and was most affected by three vital factors (antecedent SWP, total rainfall and rainfall intensity). Low antecedent SWP amplifies SWP's sensitivity to subsequent events, accelerating its response to smaller rainfalls (&lt;5 mm) compared with larger ones (&gt;15 mm). Small rainfall can increase SWP by 0.5–2 MPa in the 20-cm layer, sustaining plant physiological activities under high antecedent SWP conditions (&gt;−3.5 MPa), with a maximum average rise in photosynthetic rate of 9.20 ± 0.45 μmol CO₂ m⁻² s⁻¹, enhancing HA's water use efficiency to 1.79 ± 0.22 μmol CO₂ mmol⁻¹ H₂O.

In an attempt to evaluate the possible role of rain, dew and fog, the abundance, cover and chlorophyll content of the hypoliths on 10–20 cm × 5–10 cm cobblestones was measured at five slope locations at the hilltop (HT) and the upper parts of the north-facing (NF), south-facing (SF), east-facing (EF) and west-facing (WF) slopes, which were characterised by contrasting abiotic conditions. Within each slope location, 50 and 10 cobblestones were randomly, respectively, collected to evaluate the abundance and cover and to measure their chlorophyll content. In addition, field measurements were conducted to evaluate the ability of rain, dew and fog to wet the hypoliths. Our results indicate that (a) hypoliths were confined to cobblestones lying loosely on the ground; (b) while similar chlorophyll content characterised patches with hypoliths at all slope locations, their abundance and cover were the highest at NF and WF, followed by HT, with SF and EF exhibiting the lowest values; (c) our measurements did not show direct wetting by dew, fog or rain.

Riparian forests are highly vulnerable to hydroclimatic variability, which can significantly affect water availability in the soil on which they primarily depend. Along large rivers, hydroclimatic forcings can vary, resulting in different vegetative responses depending on the local climatic context and site conditions. To explore this, we studied riparian forest greenness along a 512-km river corridor with a 3° latitudinal gradient, analysing the relative contributions of climate (latitude, season, temperature, precipitation) and local hydrological conditions (groundwater). Here, we show that riparian forests along a latitudinal gradient respond differently to hydroclimatic controls, with vegetative dynamics that can be attenuated or accentuated by local site conditions. We combined Sentinel-2 satellite Normalised Difference Vegetation Index (NDVI) data over seven years (2016–2022) with hydroclimatic data to examine riparian forest greenness responses to latitudinal, seasonal and interannual hydroclimatic variability. We found contrasting hydroclimatic controls across the latitudinal gradient, with the northernmost sites predominantly controlled by temperature, while those further south are limited by water availability. In addition, we identified temperature as the primary driver of NDVI throughout the growing season, either positively or negatively. Late season precipitation and high phreatic water availability positively influenced NDVI, emphasising the role of local conditions in governing riparian forest resilience.

Modelling was supported by a large complex database on soil, groundwater and surface drainage water, which was used for establishing the boundary conditions for simulations, as well as for calibrating and validating the model. The model FLOWS provided the water and nutrient fluxes to the surface water, which were passed to the KWV model for their routing along the elementary fields in the experimental area and from these to the ditches and finally to the drainage channel. The modelling approach effectively predicted the water and solute distribution along the soil profile, as well as the losses of water and nutrients to the surface water. The results showed a significant amount of water and dissolved nutrients to flow quickly from the soil uppermost layer to the surface drainage network during both the irrigation season and during rainfall events. During irrigation applications, losses were mostly due to rainfall intensity exceeding the maximum infiltration velocity of the shallow soil layer in the case of sprinkler irrigation and to subsurface lateral drainage in the case of exceeding irrigation water provided by drip irrigation. This makes the Sassu plain a significant contributor of nutrients (nitrate and phosphorus) to the surface water.

This model is the cornerstone of our methodological innovation, allowing for an integrated analysis of the coupling relationship and spatiotemporal evolution of water poverty and ecological resilience. Our first innovation lies in applying this novel model, which provides a nuanced perspective on the dynamic linkages between water scarcity and ecosystem robustness. We reveal that from 2013 to 2022, there has been a significant upward trend in the comprehensive evaluation indices, with water poverty and ecological resilience witnessing a 166.13% and 204.29% increase, respectively. This underscores the substantial improvements achieved in these critical areas. Secondly, our research innovates by offering a detailed spatiotemporal analysis, highlighting the strengthening coupling and coordination degree between water poverty and ecological resilience over the observed period. The case of Wuhan, with a remarkable coupling coordination index of 9.305 in 2022, exemplifies a city that has reached a highly coordinated status, marking a significant advancement in urban environmental synergy. Lastly, our use of the Tobit model to explore the main influencing factors offers new insights into the drivers of the coupling and coordination level.
