Naturalized Decorations for HSCT Ward Environments at Peking University First Hospital

The haematopoietic stem cell transplantation(HSCT)ward serves as a temporary residence for patients following their surgical procedures,necessitating adherence to rigorous aseptic standards.However,the current atmosphere within these wards frequently contributes to feelings of depression among patients.Research indicates that a restorative environment has the potential to alleviate negative emotional states in individuals.This study utilized the HSCT ward of Peking University First Hospital as a case study to examine the decorative preferences.This investigation was conducted through a questionnaire that was informed by the patients’inherent preferences and insights derived from research on restorative environments.The results indicated that the incorporation of floral decorations,particularly those resembling sunflowers,in ward corridors,communal activity areas,and walls can significantly enhance patients’sense of hope.Additionally,it is essential to improve the environmental visual experience in the nurses’lounge and demonstration rooms for medical staff.

Optimization of Wetland Plant Selection and Configuration in Urban Water Environment Ecological Restoration Projects

In urban water ecological restoration projects,the selection and configuration of wetland plants are crucial for water quality improvement,ecological diversity enhancement,and landscape beautification.Different plants have different characteristics,and a scientific and rational selection and optimization of plant species is needed.This paper proposes an optimized plant selection and configuration scheme for urban water ecological restoration based on the ecological characteristics and pollutant removal performance of wetland plants.It analyzes the diversity,removal mechanisms,and configuration modes of wetland plants,taking into account ecology,aesthetics,and cost-effectiveness,to provide scientific evidence for wetland plant configuration and support water environment management decision-making.

Effects of Forest Restoration Techniques on Community Diversity and Aboveground Biomass on Area Affected by Mining Tailings in Mariana,Southeastern Brazil

Currently there is an urgent and special attention in actions to restore tropical forests.In this study,we evaluated the effect of different restoration methods on aboveground biomass(AGB)stock,tree community diversity and structure,in areas affected by the Fundão tailings dam collapse in Mariana,Minas Gerais state,Brazil.We measured and compiled data of the AGB,community diversity and structure attributes in 36 plots distributed in six restoration treatments and six replicas:planting of native tree seedlings with fertilization and pH correction(PSf)and without fertilization and pH correction(PS);seeding of native trees with fertilization and pH correction(SDf)and without fertilization and pH correction(SD);natural regeneration with fertilization and pH correction(NRf)and without fertilization and pH correction(NR).No significant differences in substrate properties and AGB between treatments.Although biomass storage between treatments was not statistically different,there is a clear pattern showing higher values active restoration method.The Pielou index ranged from 0.520(SDf)to 0.943(NR),except for SDf all the others treatments had values higher than 0.76.This result suggests floristic heterogeneity,without ecological dominance in the plant community.Overall,active restoration had important implications for the forest restoration where natural regeneration is limited.

Investigating the influence of street environment characteristics on perceived restoration benefits:A case study in Shenzhen

Nowadays,crowded environment and high-speed life pace are likely to bring mental stress and fatigue to citizens.How to apply achievements of the restorative environment into urban planning and environmental design has received more attention in recent years.Earlier research does not provide detailed information about the specific components of the physical environment that support restoration.This study explores which characteristics of the street environment and psychological factors of the street environment have an impact on subjective restoration.The streets were sampled from Shenzhen.Each street was represented by a single photo.The photo was quantified in terms of the different objective street components and also rated on psychological variables related to restoration.The rating on the psychological variables,being away,fascination,coherence,scope,the likelihood of restoration,and preference were provided by people of various ages and occupations.The results show that:1)the proportion of natural elements have the greatest impact on street restoration benefits and preference,and its impact is robust;2)the two characteristics of street safety and quiet are important to street restoration benefits and preferences;3)fascination and being away have a greater impact on restorative benefits of streets,followed by coherence,and the scope of the street has no significant effect on restorative benefits.The study could provide evidence for policy-makers and urban design and planning interventions.

Eco-environment Restoration and Regional Differentiation Characteristics Based on “Building Terrace and Returning Slope Farmland to Forests and Grass”

Based on the scientific and technological achievements in the past decade in the Loess Hilly-gully Region and the successful demonstration experience in Yan'an Yangou watershed, we summarize the characteristics of eco-environment restoration pattern based on "building terrace and returning slope farmland to forests and grass". According to the data on land use, slope farmland and the agricultural population in 1999, we calculate the area of new terrace that needs to be built, the area of garden plot that needs to be extended, vegetation restoration area and investment demand in counties (cities, districts). Establishing and using some indicators, such as basic farmland extension indicator, garden plot extension indicator, vegetation restoration index and investment demand density, we conduct type classification and analysis of regional differentiation characteristics in 55 counties (cities, districts). The results show that in the Loess Hilly-gully Region, 691 600 hm2 of new terrace needs to be built, 792 000 hm2 of economic forests and orchards need to be extended, 5 410 200 hm2 of vegetation needs to be restored, and the total investment demand is 15.82 billion yuan; in terms of geographical distribution, obviously there are two key areas for eco-environment restoration (one is located in the border area between northern Shaanxi and northwestern Shanxi, and the other is located in the eastern Gansu and southern Ningxia area); the classified regional guidance policies should be formulated as soon as possible, and the limited funds should be concentrated in the key areas.

Planting position and shade enhance native seedling performance in forest restoration for an endangered malagasy plant

The critically endangered tree Schizolaena tampoketsana is confined to a few diminished and degraded forest fragments on the Malagasy highlands. This habitat is vulnerable to loss due to frequent fires in the surrounding grassland that threaten to spread into the forest. One of these fragments is the focus a conservation project and here the managers aim to conserve S. tampoketsana by restoring its forest habitat to its former extent as evidenced by remnant woody plants. To inform this activity the survival and early-stage growth of seedlings of four locally native tree species were compared under contrasting conditions of proximity to the remaining forest and shade. After 12 months, seedlings of three species(Baronia taratana, Eugenia pluricymosa, Uapaca densifolia) survived better and experienced improved growth in height in grassland close to the existing forest rather than distant from it, and two survived better with shade rather than unshaded. A number of mechanisms could explain these results including reduced exposure to desiccating sunlight and winds and better soil and greater water availability close to the forest. The seedlings of one species(Nuxia capitata) survived well under all conditions. This study suggests that reforestation in these dry highlands is most feasible adjacent to remnant forest fragments and in microhabitats that minimize water loss, though young plants of some tree species may be capable of surviving in harsher conditions.

Environmental effect of vegetation restoration on degraded ecosystem in low subtropical China

Results indicated that the vegetation recovery on degraded lands significantly ameliorates surrounding environment, increases species diversity, improves soil structure, raises soil fertility, enhances productivity, and promotes regional agricultural production and social economic development dramatically. Through the combining engineering and biological measures, the restoration of degraded ecosystem in low subtropical area is possible and economical. The restoration experience in Xiaoliang, Wuhua and other sites are valuable for other degraded subtropical area was introduced.

Impact of coal resource development on eco-environment and its restoration in west of China

West China has rich mineral resources, especially in coal resources with very good mining conditions. Coal resource development is the one of important tasks in the Chinese “West Development”. Thus, the impact of coal resources development on eco-environment and its restoration is worth studying. This study shows that there are many environmental problems such as land damage, coal wastes, damage of hydro-geological condition and pollution of water resource, airborne effluents (industrial exhausts and methane emission from underground), dust, waste, water. Land damage and land desertification are the most important environmental issue in west China. Therefore, the stress of environmental restoration should be desert presentation and disturbed-land reclamation. To control environmental damages and rehabilitate the eco-environment, environmental restoration techniques are also discussed.

Numerical analysis on mechanical difference of sandstone under in-situ stress,pore pressure preserved environment at depth

Deep in-situ rock mechanics considers the influence of the in-situ environment on mechanical properties,differentiating it from traditional rock mechanics.To investigate the effect of in-situ stress,pore pressure preserved environment on the mechanical difference of sandstone,four tests are numerically modeled by COMSOL:conventional triaxial test,conventional pore pressure test,in-situ stress restoration and reconstruction test,and in-situ pore pressure-preserved test(not yet realized in the laboratory).The in-situ stress restoration parameter is introduced to characterize the recovery effect of in-situ stress on elastic modulus and heterogeneous distribution of sandstone at different depths.A random function and nonuniform pore pressure coefficient are employed to describe the non-uniform distribution of pore pressure in the in-situ environment.Numerical results are compared with existing experimental data to validate the models and calibrate the numerical parameters.By extracting mechanical parameters from numerical cores,the stress-strain curves of the four tests under different depths,in-situ stress and pore pressure are compared.The influence of non-uniform pore pressure coefficient and depth on the peak strength of sandstone is analyzed.The results show a strong linear relationship between the in-situ stress restoration parameter and depth,effectively characterizing the enhanced effect of stress restoration and reconstruction methods on the elastic modulus of conventional cores at different depths.The in-situ pore pressurepreserved test exhibits lower peak stress and peak strain compared to the other three tests,and sandstone subjected to non-uniform pore pressure is more prone to plastic damage and failure.Moreover,the influence of non-uniform pore pressure on peak strength gradually diminished with increasing depth.

生态修复目标司法确认的类型化构造

生态环境修复目标决定了生态环境修复责任的配置程度。司法确认生态环境修复目标的实践中存在损害前状态和功能的适用不合理、可接受风险水平被基本弃用和具体指向笼统模糊等问题,其原因在于司法中恢复原状思维的影响难以消弭以及现实危害的规制被过度关注。司法应当将生态环境修复目标划分为基线水平、人体健康可接受风险水平和生态环境可接受风险水平,然后根据生态环境的特质确认适宜的修复目标。对于价值较高的生态环境应当将其修复到基线水平,对于价值特殊的生态环境,即便在经济不合理的情况下,也应当将其修复到基线水平。对于人类密切相关的受污染生态环境应当将其修复到人体健康可接受风险水平。当生态环境可接受风险水平较为宽松之时可以考虑将其作为修复目标进行适用。

生态环境修复制度法典化的法理分析与规范设计

生态环境修复是生态环境质量改善的核心,也是生态环境损害救济的核心。生态环境修复制度具有环境法基本制度应具备的特质,并应当成为《生态环境法典》中的一项基本制度。生态环境修复制度在我国立法中已有一定的发展,在宏观尺度与微观尺度上皆有建构,并可具体化为法律义务、法律责任和法律措施,进而通过行政机制或司法机制实施。生态环境修复制度的法理基础在于国家环境保护义务和损害担责原则。国家义务的设立宗旨在于回应公民对良好生态环境质量的诉求、保障公民的环境权益;损害担责原则则是对国家义务的补充,旨在强调一般个体和组织对生态环境必须有合理的关照。在《生态环境法典》的编纂中,生态环境修复制度应立足国家义务本位,兼顾损害担责原则的实现,建构具体规则,完善制度内容,以体系化的规范体现于法典的对应章节中,继续强化其改善生态环境质量和救济生态环境损害的主导作用。
