【摘要】 办公人群的工作节奏和生活压力不断增大,久坐行为和精神高度集中导致身心健康问题呈高发趋势。绿地是缓解心理压力的有效资源,但参差不齐的建成环境品质导致办公人群的身心健康无法得到及时有效的恢复,恢复性环境优化成为城市健康发展的重要举措。本文以合肥市四个办公街区内的20个小型公共绿地作为研究样本,分析绿地复合环境因素,从“绿地异质性—职业异质性”双视角下分别探讨办公街区绿地恢复性环境的一般规划框架以及职业异质化绿地的规划重点,并形成体系化的优化设计策略。首先,在绿地异质性视角下,利用社群属性、物质环境特征及心理感知感官维度三组变量构建“个体—绿地”两水平回归模型,探讨其对远离性、延展性、魅力性及兼容性感知的影响。结果表明:(1)四类恢复性感知呈现“高魅力性/兼容性—中远离性—低延展性”的绿地异质性,揭示了绿地间恢复性感知的差异现状。(2)社群属性、心理感知感官维度和物质环境特征对恢复性感知分别起到基础性、强化/削弱性和关键性作用,且呈现交互作用机制。(3)绿地恢复性环境的一般规划框架应以认知恢复性感知的差异现状为基础,掌握变量作用机制并以三组有效解释变量为依据制定复合干预策略,降低异质性,以呈现较为优质的恢复性环境。其次,在职业异质性视角下,采用描述性分析、方差分析、多元线性回归模型及单变量方差分析等方法探讨感知感官维度对工程设计类、金融财经类、信息科技类和教育文化类人群恢复性感知和偏好的影响规律,旨在创造职业异质化绿地。结果表明:(1)自然性是最常感知的维度,而社会性和庇护性的感知较低。除了社会性外,其他感官维度均与庇护性感知存在显著差异。(2)通过对社会、庇护、眺望、平静安逸、文化和物种丰富性的合理组合,更易实现各职业人群较佳的心理恢复。(3)职业同质性表现在人群均倾向于提升各感官维度的环境品质,而恢复性感知的职业异质性表现在对空间性、眺望性、平静安逸性和文化性的不同规划重点上。此外,自然性、庇护性、平静安逸性、文化性和物种丰富性对人群的绿地偏好是不可或缺的,尤其对信息科技类人群具有明显的提升效果。最后,在异质性双视角下形成绿地的总体规划过程,从“绿地”和“职业社群”层面提出相应优化策略。本文拓展了办公街区小型公共绿地恢复性环境的研究范围,同时强调了职业差异的重要性,为精细化、异质化绿地的发展提供了新的研究成果与指导。更多还原

【Abstract】 The pace of work and the pressure of life of the office population are increasing,and sedentary behavior and high mental concentration lead to a high incidence of physical and mental health problems.Green space is an effective resource to relieve psychological pressure,but the uneven quality of built environment leads to the physical and mental health of office workers can not be timely and effective recovery,restorative environment optimization has become an important measure for healthy urban development.This paper takes 20 small public green spaces in four office blocks of Hefei city as research samples,analyzes the compound environmental factors of green spaces,discusses the general planning framework of restorative environment of green spaces in office blocks and the planning focus of occupational heterogeneous green spaces from the dual perspectives of"green space heterogeneity-occupational heterogeneity",and forms a systematic optimization design strategy.Firstly,from the perspective of the heterogeneity of green space,a two-level regression model of"individual-green space"was constructed using three sets of variables:community attributes,physical environment characteristics and psychological perceived sensory dimensions,to explore its impact on the perception of being away,extent,fascination,and compatibility.The results showed that:(1)the four types of restorative perception presented the heterogeneity of"high fascination/compatibility-medium being away-low extent",which revealed the difference status of restorative perception among green spaces.(2)Community attributes,psychological perceived sensory dimensions and physical environment characteristics play a fundamental,strengthening/weakening and critical role in restorative perception,respectively,and present an interactive mechanism.(3)The general planning framework of green restorative environment should be based on the difference status of cognitive restorative perception,grasp the mechanism of variable action,and formulate compound intervention strategies based on three sets of effective explanatory variables to reduce heterogeneity and present a relatively high-quality restorative environment.Secondly,from the perspective of occupational heterogeneity,descriptive analysis,analysis of variance,multiple linear regression model and univariate analysis of variance were used to explore the influence of perceived sensory dimensions on the restorative perception and preference of people in Engineering Design,Finance and Economics,Information Technology and Education and Culture,aiming to create a green space of occupational heterogeneity.The results show that:(1)Nature is the most commonly perceived dimension,while social and refuge are less perceived.Except for social perception,all other sensory dimensions were significantly different from refuge perception.(2)Through a reasonable combination of social,refuge,prospect,serene,culture and species richness,it is easier to achieve the better psychological recovery in all occupational groups.(3)Occupational homogeneity is manifested in the tendency of people to improve the environmental quality of each sensory dimension,while the occupational heterogeneity of restorative perception is manifested in different planning priorities for space,prospect,serene and culture.In addition,nature,refuge,serene,culture and species richness are indispensable for people’s green space preference,especially the Information Technology group has a more obvious enhancement effect.Finally,the overall planning process of green space is formed from the perspective of heterogeneity,and corresponding optimization strategies are proposed from the level of"green space"and"professional community".This paper expands the research scope of the restorative environment of small public green space in office blocks,emphasizes the importance of occupational differences,and provides new research results and guidance for the development of refined and heterogeneous green spaces.更多还原
