GREEN SYSTEM OF SMALL HICTORIC NOVHOROD-SIVERSKYY TOWN
O. Zibtseva, V. Kucherina 
Abstract. Small towns make up more than 75% of Ukrainian cities and they are their least studied category. Sustainable urban development requires knowledge about the current state of the cities, including their green space systems. The purpose of the study is to analyze the green space system of small historic town of Novhorod-Siverskyy in Chernihiv region according to the latest inventory (the 1991 year). It was established that for the time of Independence there were 13.6% of town territory under urban green plantations. Green plantings of special purpose were predominated, the quantity of which was 50.6% of the total. 52.2% of them composed urban forests, 29.5% were protective plantations on slopes of ravines and gullies, 12.2% were street plantations. Green plantations of limited use completed 44.2% (of which 87% were plantations of individual and social housing), and green public spaces were only 5.2% and were represented only by parks. The provision by green plantations amounted to 209.3 m2 per capita, including green space of public use was 10.9 m2 per capita. Such quantity fully complies with national norms and international standards.

More than 75% of Ukrainian cities are small towns. Implementation of the concept of sustainable non-exhausting urban development requires knowledge about the current situation of green spaces in small towns, the study of which was given the least attention. Currently, precise information about the state of the green plantations in small towns, as a rule, is absent.
The purpose of the study is to describe the green space system of small historic town of Novgorod-Siversky according to the latest inventory and to compare its ecological potential for sustainable development with international standards.
The indicator of the provision of green space per capita is used. The analysis is based on the data of the last inventory (the 1991 year), state norms and international standards.
Novgorod-Siversky town of Chernihiv region is one of the northernmost historic small town in Ukraine.. In 2001 the population was 15175 people, in 2010 - 14025 and in 2016 - 13652 people (that is, the negative demographic dynamics).
A couple of decades ago, the town has a powerful recreational potential, which now unfortunately lost. According to the latest inventory of green plantations (1991 year), the green zone of the town equals 2003 ha, including 293 ha (14.6%) within the townty. Of these, 15.3 ha were parks.
Among the urban green plantations, at the time of inventory, were dominated the green plantations of special purpose (50.6% of the total) - the situation is atypical for small cities, in which, as a rule, green plantations of limited use are prevail. Among the 148.4 ha green plantations of special purpose: 18.1 ha were streets plantings, 77.5 ha of urban forests and 43.8 ha of protective plantings on the slopes of ravines and beams. There were 129,6 ha (44,2%) of green plantations of limited use, including 112,3 ha – of individual and social development; 17.3 ha – of enterprises and organizations. 
Outside the town there were 1710 ha of green space, including 1530 ha of state-owned forests, of which 205.0 ha – a forest park. Thus, the complex green zone of the town was quite developed.
In accordance with the State Building Regulations, the norm of green space per capita should be 7 m2/person. Provision by green spaces of common use per capita is 11.76 m2/person, which is fully in line with the current standards. In addition, there were 55 m2/person of urban forests (within the town) and 146 m2/person of forest parks. The total quantity of green plantations is 209.3 m2/person and corresponds to international standards. 
It was established that for the time of Independence there were 13.6% of town territory under urban green plantations. Green plantings of special purpose were predominated, the quantity of which was 50.6% of the total. 52.2% of them composed urban forests, 29.5% were protective plantations on slopes of ravines and gullies, 12.2% were street plantations. Green plantations of limited use completed 44.2% (of which 87% were plantations of individual and social housing), and green public spaces were only 5.2% and were represented only by parks. The provision by green plantations amounted to 209.3 m2 per capita, including green space of public use was 10.9 m2 per capita. Such quantity fully complies with national norms and international standards.
In the future, it is planned to trace the dynamics of urban green space structure and provision by green plantations (per capita) based on the data of modern inventory.
