. The aim of this research is to develop more rational proposal to improve the green area on the territory of Biysk city park in terms of its recreation, protective, sanitary and hygienic, aesthetic and research purposes. The inventory of green plantations was carried out according to the method of V.S. Theodoronsky, I.O. Bogovaya by enumeration survey of growing stand on the park area. The inventory results of green areas and the assessment of green plantations health are shown in this work, the land-use planning and landscape gardening compliance of the area were examined too. According to the results of the study, the causes are established and the methods are set for the green plantations redesign of the park area. The list of arboreal and herbaceous plants and landscape design solutions were chosen by taking into account the environmental conditions of the Altai Territory.


Introduction
A modern city, regardless of its size and location, has industrial zones. Green spaces in these zones are designed to optimize the microclimate, increase the sanitizing effect and improve the urban environment from the effects of emissions. For industrial landscaping, the compositional relationship with the external environment is of great importance, which is determined by the functional purpose and location in urban development. The development of landscaping and landscaping projects in special-purpose territories should take into account the general situation, the volume of emissions from the enterprise, and the degree of their impact on human health. The creation of plantings on the territories of industrial enterprises is one of the main measures for their improvement and, consequently, for improving the working conditions of workers and employees of enterprises [1].
Greening of industrial enterprises is aimed at: reducing the impact of harmful emissions (dust, gases, etc.) on employees in the enterprise; improving the environment by equalizing the temperature and humidity of the air, protecting against the effects of winds, etc.; creating comfortable places for short-term outdoor recreation for employees; reducing the surface area and enriching the overall appearance of the enterprise territory [2].
The purpose of the research is to develop a more rational proposal to improve the situation with green spaces in the Biysk park in terms of recreational, protective, sanitary, aesthetic and research functions.
To achieve this goal, the following tasks are set: research of the reconstruction object, analysis, development of recommendations for eliminating negative phenomena in the existing green spaces, as well as creating the most favorable landscape organization in the Biysk park.

Methods and types of the Earth's remote sensing
The object of the study was the park, which belongs to JSC "Biysk Linen Company", located in the Altai Territory in the city of Biysk. The linen company produces and sells: short and long linen fiber of various numbers, linen yarn for the production of tarpaulins and technical fabrics; linen yarn for carpet production; linen twine, etc. The area of the park located next to the flax plant is 2.8 hectares. The territory of the plant is separated from the park by a fence made of concrete slabs with a height of 3 m.
The inventory of green plantings was carried out according to the method of V. S. Teodoronsky, I. O. Bogova [3,4] by a continuous list of plantings available on the object and assigning them an individual inventory number, as well as determining plant species and their biometric indicators.
A partial reconstruction is planned. In total, 55 specimens of wood species are subject to removal: ash maple (Acer negundo L.) 14 pcs., Scots pine (Pinus sylvestris L.) -21 pcs., hanging birch (Betula pendula Roth) -1 pc. and wrinkled rose (Rosa rugosa Thunb.) -19 pcs. The main reasons for the removal of plantings are non-compliance with the norms and rules of landscaping of the park next to the industrial enterprise.
The territory of the park was divided into four functional zones: quiet recreation, cultural and entertainment and children's recreation. In the quiet recreation area along the path, a hedge of brilliant dogwood (Cotoneaster lucidus Schlecht.) is designed. Plantings of rough elm (Ulmus glabra Huds.) are recommended to carry out sanitary pruning, remove withered and wind-broken branches. The road and path network is an asphalt surface with a width of 5 m.
It is also recommended to install gazebos on the site for visitors to relax. They will be accessed by concrete slab paths to maintain a unified style of the park.
The cultural and entertainment area is located closer to the river, in the eastern part of the territory. Along the paths, a hedge of brilliant dogwood (Cotoneaster lucidus Schlecht.) is also designed. Of the existing plantings, there are: balsamic poplar (Populus balsamifera L.) -6 pcs., common pine (Pinus sylvestris L.) -4 pcs., Siberian spruce (Picea obovata Ledeb.) -3 pcs., hanging birch (Betula pendula Roth) -3 pcs., ash maple (Acer negundo L.) -6 pcs., two white willows (Salix alba L.) and two wrinkled roses (Rosa rugosa Thunb.). It is recommended to plant on this site one copy of Siberian mountain ash (Sorbus sibirica Hedl. . The benches are recommended to be repaired and painted. The fountain is proposed to be cleaned of debris and restored, and the finishing tiles replaced with new ones. It is also planned to restore the gazebo and replace the embankment fence. On this site there is a destroyed building, which is proposed to be dismantled and instead place a portable summer cafe in the form of a tent. Here, visitors to the park will be able to hide from the scorching sun, as well as buy cold drinks and ice cream [5]. The children's recreation area is located in the south-west of the territory. Here it is necessary to uproot old-growth tree and shrub vegetation. In the vacated territory, it is recommended to set up two playgrounds with a sand surface: one for children from 1 to 3 years old, the other -from 3 to 12 years old. On these sites, it is planned to install children's entertainment complexes, slides and sandboxes. The playgrounds will have benches for recreation and child care. The paths to the playgrounds are made with an asphalt surface for harmony with the rest of the park. Here are preserved such trees as: hanging birch (Betula pendula Roth) -10 pcs., common pine (Pinus sylvestris L.) -10 pcs., rough elm (Ulmus glabra Huds.) -8 pcs., ash maple (Acer negundo L.) -1 pc. To create a group, we plant 9 pieces of Hungarian lilac (Syringa josikaea Jacg. fil.) to the existing remaining plantings. To create shade on the playground, the existing plants are planted with berry apple (Malus baccata (L.) Borkh.) -2 pcs. and Manchurian walnut (Juglans mandshurica Maxim.) -2 pcs. It is recommended to create a group between the paths, near the playground, from the following tree and shrub vegetation: gray spiraea (Spiraea × cinerea)-2 pcs., Manchurian walnut (Juglans mandshurica Maxim.) -1 pc., low almond (Prunus tenella Batsch) -3 pcs., Hungarian lilac (Syringa josikaea Jacg. fil.) -2 pcs., Wangutta spiraea (Spiraea × vanhouttei) -2 pcs., white turf (Swida alba L.) -2 pcs. These plants are very decorative. The Manchurian nut (Juglans mandshurica Maxim.) is decorative in the shape of the crown, leaves, inflorescences, and fruits. The bark on young trunks is light gray, wrinkled, dark gray with age, almost black. Spiraea gray (Spiraea × cinerea) is decorative in the summer color of the leaves: dull green, lighter below, the autumn color of the leaves is yellow. The flowers are white, the petals are oblong-rounded, longer than the stamens. Inflorescencessimple loose shields, densely covering the shoots. White turf (Swida alba L.) is decorative all year round: young shoots are bright coral-red, old wood is red -or olive-brown, with a beautiful bark pattern. The low almond (Prunus tenella Batsch) has a peak of decorative effect during the flowering period. Decorative properties: crown shape, color of shoots, leaves, flowers, fruits. It is for the spring abundant flowering that almonds are used in plantings on the site [6].
It is also recommended to install a gazebo on the site for a more private rest, in which guests of the park can admire groups of trees and shrubs, relax in the shade during the hot period of time. A concrete slab path will lead to the gazebo. A hedge of brilliant dogwood (Cotoneaster lucidus Schlecht.) along the path visually separates the playground from the volleyball court, which is located on the adjacent plot [7]. The sports and recreation area is located in the south-east of the territory. Here it is recommended, after leveling the soil, to install a volleyball court. The surface of the site is poured out of sand, since this is the territory of the embankment and sand covering is a more economical option. Existing plantings: rough elm (Ulmus glabra Huds.) -7 pcs., hanging birch (Betula pendula Roth) -13 pcs., ash maple (Acer negundo L.) -1 pc., Siberian spruce (Picea obovata Ledeb.) -9 pcs. Siberian spruce (Picea obovata Ledeb.) is located on the edge of the bank and the root system does not allow the spruce to linger on the surface and the trees begin to fall into the river. To prevent the destruction of the shore, it is recommended to plant a white willow (Salix alba L.). To the existing plantings of rough elm (Ulmus glabra Huds. Along the path there is a group of tree and shrub vegetation to distinguish the path from the gazebo. The following species are used here: berry apple (Malus baccata (L.) Borkh.) -1 pc., virgin cherry (Padus virginiana (L.) Mill.) -1 pc., Manchurian walnut (Juglans mandshurica Maxim.) -1 pc., Siberian mountain ash (Sorbus sibirica Hedl.) -1 pc., white turf (Swida alba L.) -2 pcs., Spiraea Vangutta (Spiraea × vanhouttei) -2 pcs., gray spiraea (Spiraea × cinerea) -2 pcs., Thunberg's barberry (Berberis thunbergii) -1 pc.
Landscaping and landscaping activities will change the balance of the object's territory, which shows the ratio of planning elements and the spatial structure of the object (Table 1).

Conclusions
The data in Table 1 show that after the reconstruction, the density of plantings in the park is 80 %. Thus, the density of trees is 71 pcs. per 1 ha (198 pcs. per 2.8 ha), with a normal
