Urban planning aspects of stability theory of ecological town planning systems

Abstract

The study of the problems of sustainable development of the ecological and urban planning system " population ↔ environment" of various levels of its functional and spatial integrity (local, regional, national, world-wide) reveals a number of fundamental provisions that establish the conceptual foundations of a new direction in urban planning science that potentially exists in certain individual works.The development of urban planning aspects of the stability theory is based on the fundamental concept of the physico-mathematical stability theory that is more developed at the present time and the research findings, which established the cyclical nature of the multilevel processes of wave development of the "population ↔ environment" system. The urban planning stability theory studies the nature of the vibrational development of urbanization processes accelerating in a multi-level ecological space.The paper reveals a number of similarities and fundamental differences in the states of stability and the dynamic pattern that are inherent in the development of living and inanimate natural systems. Regarding the differences in state of equilibrium: equilibrium is the goal of development for living systems within a certain cycle and the level of their spatial integrity. For inanimate systems equilibrium is the initial state.Concerning the differences in the stability of the location of the "center of mass": the "center of mass" should occupy the highest possible position (in the range of ecological equilibrium) for living systems; for the inanimate-to take the lowest possible position. When developing the urban develo-pment aspects of stability theory were used such concepts of physical and mathematical stability theory as: asymptotic stability; stability "in time" according to Lyapunov; stability "in space" ("stable − unstable node", "stable − nonstable focus ", "stable center"). Marked concepts are important for the analysis of multi-level processes of accelerating development of the ecological and urban planning system; forecasting the direction of its further changes; determination of focuses and parameters of application of urban planning regulatory influences; adapted sustainable development management.

Sustainable Design in Architecture (The Case Study of the Educational Process at Universities in Poland and Ukraine)

“…The accumulated material regarding the practical use of these and other concepts [5,6], as well as relevant contemporary urban planning and architectural solutions, especially during the rapid development of scientific and technical progress, requires their analysis and generalization, which is what this study is dedicated to [7,8]. Its overall goal is to present a comprehensive picture of modern urban planning and architecture in a sustainable environment, at different hierarchical levels of spatial integrity (city, building, interior), taking into account various determinants, such as ecological, economic, social, aesthetic, ethical [9,10]. Architecture in a balanced environment is not only a requirement of the present but also a postulate of the future, which determines the current world trends of urban planning, architecture, and construction [11,12].…”

“…The study of sustainable, environmentally balanced 1258 Sustainable Design in Architecture (The Case Study of the Educational Process at Universities in Poland and Ukraine) urban areas development issues, such as Ecological Urban Planning Systems (EUPS) 'population ↔ environment' in different levels of their spatial integrity, revealed several principles that outline the conceptual foundations of a new direction in the theory of urban planning -'wave urbanism' [16,17]. Within this direction the Department of Urban Planning of the Kyiv National University of Construction and Architecture (KNUCA) is forming an ecologically oriented 'Sustainable Urbanism' Scientific School, which is based on:  perception of urbanization as a natural link with the ecosystem self-regulation law 1 , which, as it turned out, is a manifestation of the fundamental law of sustainable development of open systems  the law of conservation of energy [8,16,18];  consideration of urban planning activity as a constructive space environment of 'homo sapiens' species existence [16];  apprehension of the environment as a theory of a big unification of various interactions for the sake of sustainable development and successive overcoming of growth limits in conditions of limited resources of the planet [8,9,10,16,17,19,20].…”

“…It was found that the EUPS dominant aspect of sustainable development is defined by a triad of complementary principles, namely:  'Variability of the unchanging' 2the spatial and energetic foundations of human development, such as the surface area and biological capacity of the planet, which determines the balancing and harmonization of the population interaction with the environment in the multi-level environmental space of urbanization processes deployment;  multi-level unity of urban processes oscillatory development of dynamic structures, which, with evolutionary acceleration, contribute to increasing the local EUPS potential;  inverse change in EUPS components parameters at the combined spatial levels of the urban planning object integrity (city ↔ region ↔ country ↔ world), which causes the self-organization processes at the level of cities (regions, countries) and self-regulation at the level of regions (countries, world) [9,16,19].…”

“…Consideration of the triad of sustainable development fundamental principles and the power of positive feedback joint action, make it possible to determine the adaptive management urban planning principles of urban areas sustainable development, using the potentials:  'Mosaic nature of asynchronous development' of territories, which is determined by the different levels of EUPS development and the presence of separate areas at earlier stages of development, that is, those that have a reserve of demographic capacity (the author developed and tested the methodology for calculating this capacity);  'Spatial kaleidoscope inertia' of changes in urban areas, the effect of which is determined by the rate of acceleration/dynamics deceleration of the wave process of the EUPS functional components development in the multi-level environmental space of the population interaction with the environment [9,16,17].…”
