Urban Environment Design: New Methodological Approaches Based on the Biosphere Compatibility Paradigm (Part 2)

Постановка задачи. Новые вызовы современности существенным образом влияют на методологию градостроительства. Актуальной научной задачей, требующей выявления закономерностей функционирования городских элементов планировочных структур (жилых районов), следует считать разработку новых принципов жизнедеятельности города, регламентирующих биосферную совместимость городов и развитие человеческого капитала. Результаты. В работе получили развитие методологические основы градостроительного планирования, проектирования и оценки вариантов проектных решений жилых планировочных единиц города (квартала, микрорайона, жилого района) на принципах парадигмы биосферной совместимости городов и поселений, развивающих человека. Предложена концептуальная модель функционально-планировочной организации территории - иерархия функций города. Разработан алгоритм оценки вариантов проектов планировки жилых районов на основе индекса обеспеченности городскими функциями. Для каждой из функций города определен необходимый и достаточный состав индикаторов оценки проектных решений. Обсуждается перспектива количественной оценки социального благополучия населения жилых районов биосферосовместимого города как безальтернативного условия формирования комфортной городской среды. Вывод. Выполненная численная оценка проектного решения и сравнительный анализ уровня благоприятности жилого микрорайона с использованием принципов парадигмы биосферной совместимости показывают, какие изменения требуются в составе градостроительных решений не только для достижений качества материальной среды жизнедеятельности, но и для развития человека во всех отношениях. Statement of the problem. New challenges of our time significantly affect the methodology of urban planning. The development of new principles of city life, regulating the biosphere compatibility of cities and the development of human capital, should be considered an urgent scientific task that requires identifying the patterns of functioning of urban elements of planning structures (residential areas). Results. The paper develops the methodological foundations of urban planning, design and evaluation of design options for residential planning units of the city (quarter, neighborhood, residential area) on the principles of the paradigm of biosphere compatibility of cities and man-made settlements.. A conceptual model of the functional and planning organization of the territory-the hierarchy of city functions is set forth. An algorithm for evaluating variants of residential area planning projects based on the index of urban function provision has been developed. For each of the functions of the city, the necessary and sufficient composition of indicators for evaluating design decisions is identified. The article discusses the prospect of quantifying the social well-being of the population of residential areas of a biosphere-compatible city as an alternative condition for the formation of a comfortable urban environment. Conclusion. The numerical evaluation of the design solution and a comparative analysis of the level of favorability of a residential neighborhood using the principles of the biosphere compatibility paradigm show what changes are required in the composition of urban planning solutions not only to achieve the quality of the material environment of life, but also for human development in all respects.

Networked Compact City Policy Status and Issues—Hierarchy and Human Mobility in Tokyo, Japan

As a policy to promote compact cities, Japan formulated the Location Normalization Plan (LNP) in 2014. By this plan, each municipality is promoting the establishment of Urban Function Induction-encouraged Areas (UFIA) in which life service facilities are to be provided. The role of the UFIA in the region might differ depending on the city scale and the UFIA hierarchy. For this study, using the Tokyo Person Trip survey, we specifically examined the mobility of people and clarified differences in the hierarchical nature of UFIA to ascertain the current status and issues of UFIA. Consequently, we obtained the following information for the realization of compactness. (1) The actual conditions of traffic characteristics and facilities differ depending on the UFIA hierarchy. Moreover, considering these hierarchies during the study of UFIA is important. (2) Sub-core UFIA in cities with a large population have a narrow usage area and a high ratio of traffic-sharing between walking and bicycling, which might engender the construction of compact living areas. (3) However, sub-core UFIA in cities with a small population have a high ratio of traffic-sharing of automobiles and a wide usage area, which presents challenges for compact city realization.

The development of new principles of city life, regulating the biosphere compatibility of cities and the development of human capital, should be considered an urgent scientific task that requires identifying the patterns of functioning of urban elements of planning structures (residential areas). Results. The paper develops the methodological foundations of urban planning, design and evaluation of design options for residential planning units of the city (quarter, neighborhood, residential area) on the principles of the paradigm of biosphere compatibility of cities and settlements that develop people. A conceptual model of the functional and planning organization of the territory- the hierarchy of city functions - is proposed. An algorithm for evaluating variants of residential area planning projects based on the index of urban function provision has been developed. For each of the functions of the city, the necessary and sufficient composition of indicators for evaluating design decisions is identified. The article discusses the prospect of quantifying the social well-being of the population of residential areas of a biosphere-compatible city as an alternative condition for the formation of a comfortable urban environment.Conclusion.

Urban Region Function Mining Service Based on Social Media Text Analysis

Urban region functions are the types of potential activities in an urban region, such as residence, commerce, transportation, entertainment, etc. A service which mines urban region functions is of great value for various applications, including urban planning and transportation management, etc. Many studies have been carried out to dig out different regions’ functions, but few studies are based on social media text analysis. Considering that the semantic information embedded in social media texts is very useful to infer an urban region’s main functions, we design a service which extracts human activities using Sina Weibo ( www.weibo.com ; the largest microblog system in Chinese, similar to Twitter) with location information and further describes a region’s main functions with a function vector based on the human activities. First, we predefine a variety of human activities to get the related activities corresponding to each Weibo post using an urban function classification model. Second, urban regions’ function vectors are generated, with which we can easily do some high-level work such as similar place recommendation. At last, with the function vectors generated, we develop a Web application for urban region function querying. We also conduct a case study among the urban regions in Beijing, and the experiment results demonstrate the feasibility of our method.

The Role of Land Use Transition on Industrial Pollution Reduction in the Context of Innovation-Driven: The Case of 30 Provinces in China

With the world calling for environmental protection, China has to follow an innovation-driven development path in order to achieve its own high-quality and sustainable development. During this period, the problem of inefficient land use resulting from rapid progress in urbanisation is difficult to ignore. This study uses data from 30 provinces in mainland China to analyse the environmental protection effects of land use transition towards innovation-driven development, using spatial econometric models and entropy method. The results show that the innovation-oriented land use transition in four dimensions, human capital, material capital, urban function and government, is conducive to reducing industrial pollution emissions in the region, but this effect does not have a spillover effect. The results of this study provide some insights into the “triple-win” (environmental protection, innovation and land-use optimisation) approach to economic development in China.
