Urban planning motivations and sustainable development of the territory

Urban development aims to ensure a growth of the population's welfare, on the one hand. On the other band, it has to secure the ecological equilibrium and keep the historical and cultural "memory" of the territory. Urban activity is induced by motivations. Motivations are imprinted in corresponding territory structures called cityscape patterns. Motivations can conflict with each other, main conflicts being between: 1. economy and ecology, 2. the social and the private, 3. aesthetics and information, 4. the material and the spiritual. The conflicts are caused by contradictions concerning the landscape and its spatial design. The basis of sustainable development is the landscape. The basis of the landscape is the Earth's crust Surface and relief The landscape features depend on the relief in the following way. The landscape ecological value depends on its biological productivity and increases from the top to the lowland. On the contrary, the ecological resistance increases from the lowland to the top. As a result, the following sustainable development criteria can be formulated for town planning. 1. In urban activities, all motivations should be realized. If at a given time the shares of the motivations realized are equal, we call such a development sustainable. 2. Proportions in the elemental landscape urbanization intensity must correspond to their values and resistance. 3. The historical and cultural landscapes should keep their uniqueness, authenticity and integrity.
