The definition of eco-physical basis of a sustainable development was based on the analogies reveal between the mankind development on various levels of system-territorial integrality and the ecological processes dynamics of “different physics”. There were esteemed ethnogenesis conceptions by L. Gumelev, ecosystem self-adjustment by V. Dolnik, demographic transition by S. Kapitsa, cities dynamics by G. Forester. It was identified that the basis of ethno-, eco-, demo- and urbanistic system is an integral self-replicating thermodynamical model, which can exert in course of consistent shift of phases and phases transit. Development phases shift is stipulated by the alternating change of an attitude between the demography capacity parameters and the population quantity on certain territory. The categories “ethnic homeostasis”, “stable population” and “urban territories balance” depict the core of “ecological balance” phenomenon, under the condition of self-adjusting interaction of the population and environment. The sustainable development is a fluctuating process in a normal changes spectrum, which depends on population-environment ecosystem development phase.

An estimation of urbanization process in the ecological space of population displacement, staring from separate cities and ethnoses to the whole mankind, illustrated certain parallels between the ecological and physical interactions. It is discovered that the ecosystem self-adjustment mechanism defines the urban territories development as an ecological city planning system. In this aspect, land invasion becomes a goal-directed and predicted process, which undergoes management influence. This process has the goals with certain parameters – sustainable development in the ecological balance spectrum. This balance is described in terms of a proportion 1:1, between the population quantity and the environment (with a permissible variation 10% in spectrum). The proportion 1:1 is a fundamental dimensionless constant of strong interaction in physics. Weak interaction is observed during demographical transition, when a human life-time synchronization and a duplication of mankind leads to malfunction of growth and hazard of “radioactive” disintegration of complicated structures. As to the gravitation. Gravitational inhomogenuities, which have given an impulse to the stars and planetary systems creation, competed with each other. Just like that the cities compete for the territories invasion. Attractiveness – as a some kind of “magnetism” of territory in the ecological aspect reflects itself in a growth of quantity (in a natural or mechanical way). An exhaustion of growth possibilities “rejects” the population and leads to quantity reduce. The defined analogies give evidences that:

• urban ecosystems are only metastable, it is only enough to support their integrity and overcome the tendency of stochastic disintegration. They should exist in an oscillatory regime. It may give a chance to slow down an accelerating process of development and coordinate growth rates of all components;
• in the ecosystem context, urbanization phenomenon expresses its “super gravitation”, which is reflected by means of ecological influence onto four fundamental physical interactions (strong, weak, electromagnetic and gravitational).

The definition of urbanization eco-physical basis (more than a half of world population lives in cities) will give a chance to forme scientifically validate policy of sustainable cities, regions and countries development. Based on the abovementioned, the national and local strategies of environmentally safe, balanced and sustainable development is proposed to develop in view of potential of natural regions, which have a demographic stock capacity. These regions were found during the study of possibilities, directions and parameters of sustainable development of Ukraine. The ecological age of its regions, as eco-urban city systems, are defined on the basis of comparison with the population demographic parameters of their capacity (calculated by the method of the author). These defined the possible regionalization of the territory and helped to suggest a transformational model of resettlement planning, which ensures the spatial terms of environmentally sustainable, balanced and safe development of the country for which the question of stabilization of the population provides the guideline features in its national security.
