♦ ANALYZING URBAN PLANNING
Author: ZHANG Tingwei
ABSTRACT: This article reviews the transformation of the American planning profession since the 1980s, highlighting the global trend of urban planning adapting to external economic and political changes. By remaining grounded in its core principles while responding to changes, urban planning will not only continue to be essential but also gain opportunities for renewal. Under the new circumstances, urban planning should undergo a renewal-oriented transformation by preserving its core while embracing innovation, rather than fading into obsolescence. To achieve renewal-oriented transformation, planners need to dynamically understand the nature of planning, adapt to changes in the scope of their work and service, make good use of new tools, and more importantly, improve planning concepts.

♦ DEEP SOLITUDE: INFORMATION TECHNOLOGY, EVERYDAY LIFE, AND LEFEBVRE’S CRITIQUE - DISCUSSION ON SPACE AND PLANNING IN THE INFORMATION AGE
Author: YANG Yuzhen
ABSTRACT: In the third volume of his Critique of Everyday Life, published in 1981, Henri Lefebvre pioneered the exploration of relationship between information technology and everyday life, imbued with a sense of “aura” and a holistic problem consciousness at a historical turning point. This paper examines Lefebvre’s analysis and judgment on the six aspects of the information technology society, discusses the social value of proximity and planning under this situation, and finally explores the space and planning in the information age. It argues that there is a need to go beyond treating information technology as a practical technology, and that without critical thinking, it is difficult to achieve true creativity and quality development.

♦ IMPACT OF POLYCENTRIC SPATIAL STRUCTURE ON THE INNOVATION PERFORMANCE OF CHINESE CITIES: EVIDENCE FROM 279 CITIES AT OR ABOVE THE PREFECTURE LEVEL
Author: QIAO Yibo; LUO Zhendong
ABSTRACT: This paper builds a panel dataset composed of 279 cities at or above the prefecture level from 2001 to 2016, and uses panel two-way fixed effects model to explore the impact of polycentric spatial structure on the innovation performance of Chinese cities. The polycentricity degree of urban spatial structure is obtained by identifying the LandScan dataset and comprehensively considering the population, distance, and area of each center, and the urban innovation performance is characterized by the number of patent applications per 10,000 people in the city. The research results show that the polycentric spatial structure has a significant positive impact on urban innovation performance, and it is only valid for economically well-developed cities. The results also indicate that, during the sample period, the increase of investment in science and education, population agglomeration, economic development, and improvement of public services can promote urban innovation performance, while the investment-driven urban construction has a certain restrictive effect on urban innovation performance. The paper provides support for the feasibility of polycentric spatial structure in urban planning practice, and also puts forward corresponding policy implications.

♦ EXPLORATION ON INTEGRATED LANDSCAPE APPROACH FOR PARK CITY PLANNING: A DIGITAL PLANNING METHOD FOR THE COUPLED DEVELOPMENT OF ECOLOGICAL NETWORK AND PUBLIC SPACE IN URBAN BUILT-UP AREAS
Author: XU Ning; WANG Pu; ZHANG Xiao
ABSTRACT: In the context of ecological civilization, the completeness of ecological network and the enhancement of public vitality are vital for the high-quality development of park cities. Different from the conventional thought of equating park city construction with incremental development of green space and non-construction land, this paper proposes building a coupling system of ecological network and public space as a global framework for park city construction from an integrated landscape perspective. With the support of a range of digital landscape planning technical methods, the simulation and analysis software such as ENVI, GTB, and ArcGIS are applied to identify, analyze, and evaluate the ecological network and public space in the main city of Nanjing in terms of structure, function, and demand, based on which an integrated landscape planning method for the coupled development of urban ecological network and public space is developed. This method aims to guide the reshaping of urban morphology and the optimization of spatial pattern, achieve the efficient and intensive park city development, and provide scientific basis and practical support for the master planning of park cities.

♦ CONCEPTUAL FRAMEWORK OF INDIGENOUS URBANISM AND PROSPECTS FOR CHINESE PLANNING
Author: WANG Shifu; LIU Lianbi; LIU Zheng
ABSTRACT: While “urbanism” has become a prominent thought, concept, and practice in urban planning, systematic theoretical reflection on its foundations and implications remains insufficient. This study identifies ideas, actions, and results as key perspectives for understanding urbanism based on a review of literature and theoretical analysis related to urban society and planning design. Coupled with urban theory, planning theory, and planning methods, it develops a conceptual model of urbanism and applies it to interpret urban planning practices in China’s urbanization process. The indigenous urbanism in China is characterized by clear top-level guidance, proactive planning interventions, and significant urbanization outcomes. Despite a considerable accumulation of planning method and experience, the localization of urban theory and planning theory remains underdeveloped. Looking forward to the trends and requirements of China’s new urbanization model, this study proposes a concept of “Chinese planning” rooted in indigenous urbanism. Guided by Chinese modernization, it emphasizes outcome-oriented, high-quality development and spatial governance, jointly committed to generating Chinese planning theory and urban theory during the urbanization with Chinese characteristics.

♦ SPATIAL PATTERN OF CHINA’S POPULATION URBANIZATION FROM THE PERSPECTIVE OF POPULATION MIGRATION: A STUDY BASED ON BAIDU MIGRATION DATA
Author: NIU Xinyi; ZHU Yi
ABSTRACT: This paper measures the spatial pattern of China’s population urbanization formed by population migration in the process of urbanization by using Baidu Migration Data. Selecting Baidu Migration Data of two periods, i.e., before the Spring Festival and ordinary days, and using prefecture-level cities as spatial units, the paper analyzes the spatial pattern characteristics and influencing factors by obtaining the distribution and migration direction of the migrant population after comparing the characteristics of intercity travel between the period before the Spring Festival and ordinary days, and using local spatial autocorrelation and other methods. It is found that China’s population urbanization has formed a spatial pattern of north-south differentiation from the perspective of population migration. Southern China is the highvalue clustering region for migrant population, and northern China is the low-value clustering region. The LISA (Local Indicators of Spatial Association) results show a north-south differentiation that is basically consistent with the “Qinling-Huaihe Line”, which is obviously different from China’s socioeconomic spatial distribution characteristics of eastern, central, and western regions. The phenomenon of north-south differentiation in population urbanization is related to the differences in the impacts of the three urban agglomerations, which are the Yangtze River Delta, the Pearl River Delta, and Beijing-TianjinHebei Region, as well as the differences in the intraprovincial urbanization process between the north and south regions. The pattern of prefecture-level cities in southern China is driven by large-scale inter-provincial urbanization in which the population is migrated to the three major urban agglomerations, along with intra-provincial urbanization in which the population is migrated to provincial capital cities. The pattern of prefecture-level cities in northern China is a result of both weakened inter-provincial urbanization in which the population is migrated to the three urban agglomerations and weakened intraprovincial urbanization in which the population is migrated to provincial capital cities.

♦ IMPACT OF HUMAN-SCALE STREET SPACE QUALITY ON WALKING TO SCHOOL BY SCHOOL-AGE CHILDREN: A CASE STUDY OF BEIJING
Author: WANG Xiaoge; HUANG Duoduo; LIU Ye; YAO Yao; XIANG Lili
ABSTRACT: Improving the quality of street space can not only promote children’s physical activity and their health, but also push forward the construction of child-friendly cities in China. Previous studies on the associations between the built environment and walking to school by school-age children are insufficient, and have paid little attention to humanscale street space. Using the traffic survey data of Beijing in 2015 in combination with streetscape and basic geographic information data, this paper identifies the built environment elements that affects school-age children’s choice of walking to school, especially the street space elements at the human scale, and controls the possible deviations caused by residential self-selection. Results show that: street walkability and vitality are significantly correlated with the probability of walking to school by school-age children, and the children with better socio-economic conditions are more likely to walk to school due to the improvement of street space quality; after controlling the residential selfselection deviations, the street space quality still has a significant correlation with the probability of walking to school. This study can provide a scientific basis for the evaluation of street space quality and the construction of child-friendly cities.

♦ SPATIAL FORM CHARACTERISTICS AND INFLUENCING FACTORS OF RAILWAY STATION AREAS: A CASE STUDY OF WUHAN METROPOLITAN AREA
Author: ZHOU Xilin; GUO Ziyu; XIONG Zhijian; LI Chuancheng
ABSTRACT: The space-time compression effect caused by railway construction has promoted the integrated development of urban agglomerations. However, different railway station areas within the metropolitan area differ in developmental characteristics, and there is still little systematic quantitative research on the influencing factors. With passenger railway stations in Wuhan metropolitan area as research subjects, this paper obtains the spatial form indicators of station areas, such as land built rate, building coverage rate, height, and floor area ratio (FAR), and summarizes the spatial form characteristics of station areas guided by high-speed, intercity, and general-speed railroads using the typology analysis method. Then the paper examines the correlation between the spatial form indicators of station areas and the potential influencing factors. The results show that the land built rate has a significantly positive correlation with the annual GDP of districts/counties and the proportion of the tertiary industry, while a significantly negative correlation with the distance between the station area and the administrative center. In addition, the FAR has a significantly positive correlation with the number of years since the completion of the station. Further analysis shows that the impact of GDP on the built rate is much higher than other factors, and a long period of development is an essential requirement for the high-intensity development in the peripheral circle of the station area.

♦ INFLUENCE OF URBAN BUILT ENVIRONMENT ON LAND SURFACE TEMPERATURE AND ITS SPATIAL RELATIONSHIP
Author: ZHENG Dianyuan; HUANG Xiaojun; QI Mingyue
ABSTRACT: The built environment in cities is the main influencing factor of land surface temperature (LST) variation. Taking Beilin District of Xi’an as an example, this paper uses the multi-source spatial data, as well as the multivariate logistic regression and spatial statistical models on a grid scale of 30 m × 30 m to deeply explore the influence of the urban built environment on the surface temperature and its spatial relationship at the micro scale. The results show that: (1) the spatial agglomeration characteristics of LST in Beilin District fall into two main types: “high-high (H-H)” and “low-low (L-L)”, forming a heat island area in the northern part and a cold island area in the eastern part of the study area; (2) the main warming factors for the LST within a city are the normalized difference impervious surface index (NDISI) and building density (BD), and the cooling factors are road density (RD), percentage of water (PW), building height standard deviation (BHS), while the normalized difference vegetation index (NDVI) is less effective in cooling low temperature areas with water bodies and better in high temperature areas without water bodies; (3) the RD and BHS are negatively correlated with the LST, especially in high temperature areas; (4) the urban LST has substantial spatial dependence in space, and there is a significant spatial diffusion effect between the local and adjacent LSTs under the influence of the built environment.
