On technology development of landscape and woodlands formation in the green zone of cities(by example of Astana)

The object of the present study is a landscape group, ordinary and mixed, forest plantationsof the main forest species in the green zone of Astana. The purpose of this research is scientific justification for the most economical andefficient methods for growing plantations, based on the study of growth and determination of the survival rate and state, as well as onmaking recommendations on technology of the forest park landscapes. The study revealed that RSE Zhasyl Aimak has over 21 thousandhectares of forest plantations of tree and shrub species, of which only 1170 ha are transferred to the forest area. Coniferous speciesaccount for the Scotch pine, which grows well in this type of soil. The study found that plantations in semi-open green spaces form thebest microclimate conditions conducive to relaxation. According to the control and evaluation of forest crops, the causes of the poorstate of forest plantations were the following: lack of water  43.7%, damage to domestic animals  8.9%, substandard planting material 45.2%, failure to conduct activities  0.7%, poor organization of the event  0.3%, errors in the selection of species  1.2%. Thehighest percentage accounts for the lack of irrigation and non-standard planting material. We believe that the design of planting shouldaccount for the increase the duration of plants watering, especially in these soil and climatic conditions, for introduction of advancedmethods of growing seedlings in nursery gardens, and for strengthening their own control over the quality of planting material whenbuying it from third parties. In this regard, an important aspect of improvement is the selection of an adequate range of woody plantsthat are resistant to the effects of the negative factors that take place in urban areas (human-made pollution, soil compaction, adverseclimatic conditions). It should be noted that plantations should consider not only such properties of trees as environmental sustainability,longevity, sanitary and decorative qualities, but also their functional purpose. It is therefore important in each case to evaluate the impactof the negative factors of urban environment on the growth and development of plants and rocks to select such species that will be mostappropriate for their intended purpose in these conditions. When planting the urbanized territory, it is necessary to study in detail theconditions of plant growth in the suburban environment, develop a regular system of care and select the species with the required environmentalfeatures, as well as valuable aesthetic and architectural properties.
