The ecological and social problems brought about by China’s rapid urbanization process threaten sustainable development. Taking the cities with high and coarse sediment yield in the middle reaches of the Yellow River as the research objects, this study constructed a complex analytical framework composed of urbanization, ecosystem service value (ESV), and human well-being (HBW) subsystems. The equivalent factor method (EFM) was used to evaluate the ESV. The entropy weight method (EWM) and the comprehensive nighttime light index (CNLI) were adopted to assess the level of urbanization and human well-being. Then, coupled coordination degree (CCD) and grey relational modes were developed to reveal the level and major obstacles of synergistic development. The results showed that, from 2000 to 2020, urbanization, ESV, and HWB increased. The average value of CCD grew from 0.34 to 0.56, with higher coordination levels in the northeast and south. The coordinated development is influenced by multiple factors, with the intensity of the driving factors decreasing in the order of industrial structure, population quality, economic drive, government regulation, and scientific and technological support. The results indicate that it is essential to formulate differentiated regionally coordinated development strategies and establish cross-regional cooperation mechanisms to achieve interactive urban economic development, ecological protection, and well-being improvements in the middle reaches of the Yellow River.

Riparian buffer zones are transitional and ecological intersections between land and water. These areas play a major role in advancing ecosystem protection and restoration. Here, we investigated the spatial and temporal evolution of land use, ecosystem service value (ESV), and landscape ecological risk (LER) in riparian buffer zones between 1990 and 2020 using the Shaanxi section of the Weihe River as a case study using a GIS grid, the unit- area-equivalent-factor method, the landscape ecological risk index, and the natural breakpoint method. We also established four ecological zones using standardized Z-scores. The predominant land categories in the study area comprised cultivated, construction, and grassland, which together accounted for more than 80 % of the total area. The construction land demonstrated the most significant increase of 4,062.33 hm2 2 area, and cultivated land showed most significant decrease of 13,048.56 hm2 2 area, between 1990 and 2020. Next, study-site ESV increased from 28.30 x 108 8 CNY in 1990 to 28.94 x 108 8 CNY in 2020, reflecting 2.26 % growth. High-value areas were principally bodies of water and primarily situated along the Weihe River, extending from west to east along the main channel. The LER of the study area was dominated by the lowest ecological risk, low ecological risk, and medium ecological risk classes, which collectively accounted for more than 70 % of the total area. The main land types in the areas with high ecological risk were forest land and cultivated land. The study area's LER demonstrated a decreasing trend from 1990 to 2020, and the area with the lowest ecological risk and low ecological risk zones increased by 9.97 %. The riparian buffer zone was divided into ecological restoration, reconstruction, conservation, and protection zones based on two factors, namely, ESV and LER. The most dominant of these was the ecological reconstruction zone, which showed a 13.75 % decrease in area share between 1990 and 2020. The ecological restoration zone occupied the smallest area with the largest increase of 56.63 % during this period. In conclusion, this study contributes to ecological zoning and management of the riparian buffer zone along the main channel of the Weihe River. Appropriate zoning is integral to protecting this valuable ecosystem and achieving sustainable development of surrounding human communities.

Based on the perceptions of college student participants in winter and summer, the effects of different vegetation structures within landscapes (single-layer woodland, tree-shrub-grass composite woodlands, tree-grass composite woodland, and single-layer grassland) and concrete squares without plants were investigated, and the skin conductivity level (SCL) and environmental perception recovery score (PRS) associated with landscape types were calculated. The results indicated that seasonal differences in landscape perception significantly affected college student participants' PRS but not their SCL scores, both in winter and summer. Viewing single-layer and tree-shrub-grass composite woodlands in summer, as well as single-layer woodland in winter, enhanced the environmental perception of the college student participants. The restorative effects of the four vegetation types in green spaces were ranked as follows: single-layer woodland, tree-shrub-grass composite woodlands, single-layer grassland, and tree-grass composite woodlands and concrete squares without plants. These findings underscore the importance of considering seasonal variations when choosing plant species for landscaping purposes, with evergreen single-layer woodland being a suitable choice for winter urban landscapes. This provides a scientific basis for assessing landscape perception and preferences in the future.

This study investigates the spatial-temporal evolution and the interconnectedness of land use/cover change (LUCC) and ecosystem service value (ESV). Such analysis can offer theoretical guidance and support decision-making for sustainable land resource development and ecological preservation in ecologically vulnerable cities within the Loess Plateau-Maowusu Desert transition zone. Utilizing Landsat data spanning 2000–2020, the paper examines the synergistic relationship between ESV and land use intensity in Shenmu City through bivariate spatial autocorrelation and the coupled coordination degree (CCD) model. Our findings indicate that the area of construction land in Shenmu City experienced the most significant change between 2000 and 2020, with a dynamism rate of 76.8%. This shift resulted in a decrease in the total ESV, from RMB 10.059 billion in 2000 to RMB 9.906 billion in 2020. The bivariate spatial autocorrelation analysis reveals a significant positive spatial correlation between ESV and land use intensity, while the CCD levels for both demonstrate a fluctuating yet overall upward trend over the 20-year period. The paper uncovers the spatial-temporal evolution of LUCC and ESV in Shenmu City along with their interconnected dynamics. The research outcomes can contribute valuable insights for reinforcing land resource utilization and promoting sustainable regional development within cities in the Loess Plateau-Maowusu Desert transition zone.

为探究城市快速路中央分隔带线性空间布局形式的视觉刺激对驾驶行为的影响,通过图像语义分割技术量化景观构成要素,并用SILAB软件平台构建虚拟仿真场景,开展模拟驾驶试验.测试路段限速值分别为50 km·h-1和70 km·h-1.试验获取了 41名被试对中央分隔带布局形式视觉刺激的眼动和车辆运行指标以及驾驶疲劳的主观评价,以分析不同中央分隔带布局形式视觉刺激下各特征参数的变化规律.采用注视点信息熵作为布局形式视觉刺激度的量化指标,并使用ROC曲线方法为表征不同中央分隔带布局形式视觉刺激的驾驶行为指标确立了舒适性阈值,根据不同中央分隔带布局形式下的驾驶行为指标及阈值,建立了舒适性综合判别模型.研究结果表明:单次扫视时长、注视次数、车道横向偏移距离受布局形式视觉刺激的影响较大;与车速50 km·h-1相比,当车速为70 km·h-1时,扫视频率低,单次扫视时长短,注视次数少,平均眨眼持续时间长;注视点信息熵与视觉刺激度相关;由车辆运行特征分析可知,排列式的中央分隔带布局形式由于景观单调、视觉刺激过低会导致驾驶人出现反应迟缓、疲劳,影响行车安全;规则式布局形式视觉刺激过高,环境的复杂性、新奇性、意外性等特征过于显著,会导致驾驶人难以集中注意力,从而威胁行车安全;而自然式的布局形式不仅能够改善城市快速路景观环境的单调性,还能够提供适宜的视觉刺激.研究成果能够改善中央分隔带布局形式及提高驾驶安全性提供一定的理论依据.
