Abstract: The subject of this research is the peculiarities of formation of sustainable architectural environment using green photobioreactors – a technical devices that ensures specific conditions for the life cycle of microalgae. In global practice, this direction is known as “Algaetecture”. The authors define “Algaetecture” as a set of measures and means for the formation of environmentally sustainable urban environment, based on the integration of green photobioreactor systems into the structure of open and closed urban spaces. The research demonstrated that the spatial characteristics of objects containing photobioreactor systems are directly associated with the conditions for the life cycle of microalgae. Modelling of the shape for enduring the life cycle of microalgae is one of the leading factors in the formation of volumetric planning characteristics of buildings, development of landscape design of the vicinity, and architectural solution of the photobioreactor systems themselves. As a result, the author determines the main methods of creating urban environment that maximize the efficiency of based on photobioreactors green systems that are integrated into the building. This includes: consideration of local climate peculiarities in development of spatial characteristics of the buildings, namely for redistribution of solar radiation; use of various techniques for the formation of multilayered, weather-adaptive façade envelopes and roofs of the buildings; ensuring the interface between the architecture of external photobioreactor systems and interior environment of the buildings for creating the inside light and heat comfort; formation of the vicinity open spaces and surfaces of the building that contains photobioreactors, as a unified system that regulates insolation and wind streams; combination of different photobioreactor systems and microalgae cultures, including in the one particular architectural object. Based on the acquires results, the author offers solutions for the volume, surfaces and territory of a building that includes photobioreactor systems, considering the specificity of the monsoon climate of Southern Primorye. The recommendations are elaborated on the development of the architecture of photobioreactor systems for the facades of buildings depending on their expansion into the main sectors of the horizon.

Abstract: This article explores the prerequisites for sustainable development of island territories of the Gulf of Peter the Great that retained their autonomy from continental Vladivostok – AskoldIsland, Popov Island, Reyneke Island, Rikord Island, Putyanin Island. A brief overview is provided on the development of islands in prerevolutionary and Soviet period, as well as at the turn of the XX – XXI centuries. It is noted, that the initial period of islands territorial development (late XIX – early XX centuries) is characterized with sustainable natural resource management based on consideration of the local landscape, natural and climatic conditions. Computer modeling of the annual course of wind and insolation regime of island territories is conducted for elaboration of the advanced models of sustainable natural resource management. This allowed determining comfort and discomfort landscape areas of the indicated islands for the three main seasons – winter, spring-summer, and summer. Typical terrain contributes to localization of the comfort and discomfort zones. At the same time, comfort and discomfort zone would be specific for each of the three seasons, which should be considered in arranging various types of recreation activities. Based on the results of studying the peculiarities of socioeconomic development of the islands and their landscape-climatic specificity, the author highlights three groups of islands and suggests models of sustainable development for each group: 1) Model of full-scale economic-recreational development with restoration of the collapsed ecological framework  (Popov Island and Putyanin Island); 2) Model of autonomous development with restoration of the collapsed ecological framework (Reyneke Islan); 3) Model of economical development (Askold Island, Rikord Island). The author develops the schemes of territorial development of the islands, and suggests projects on formation of sustainable environment of rural localities and tourist routs.

Abstract: This article examines the peculiarities of formation of the sustainable urban environment in the conditions of rugged terrain and monsoon climate common for the city of Vladivostok, based on restoration of its natural hydrological cycle. The authors provide a brief overview of the current state of research on the topic of restoration and preservation of the natural hydrological cycle in urban environment; analyze the impact of the landscape-climatic factors upon the formation of hydrological cycle in the territory of Vladivostok; assesse the initial state and anthropogenic transformation of the natural carcass and water-collecting fabric of the landscape in the course of urban development of the south of the Muravyov-Amursky Peninsula. The research method contains the systematization of theoretical knowledge and design practices in the field of formation of the sustainable urban environment in the conditions of water system renovation the analysis of interaction of the urban planning pattern with the landscape and water system of the territory in accordance with the cartographic data of various years; on-side survey of and experimental design for the Obyasnenie River in Vladivostok. As a result, for the initial natural landscape of Vladivostok, are determine the three types of section of water-collecting fabric based on the seasonal variation of their contribution into the water content of the river system. The authors develop the index map of the water and landscape subsystems of the natural carcass of Vladivostok. Their correlation with the transport carcass and industrial zones allowed identifying the problematic territories and renovation reserves of the water system. In conclusion, the authors formulate the key directions in restoration of the natural hydrological cycle in urban territory as the foundation for formation of the sustainable urban environment within the region.
