The aim of the study. Research the tourism and recreational activities of residents and visitors of the city of Lviv regarding the ecological state of green zones which perform a number of important functions, including social and environmental, which is to ensure that the residents of the city have the most favorable environmental conditions. Method. It is analized that within the Lviv urban ecosystem a green zone is allocated, that is, a system of territories with green plantations in unoccupied open spaces within a city or suburban area which have ecological, economic, recreational and aesthetic importance. The tourist and recreational use of the green zone has a significant negative impact on its condition. Results. The tourist and recreational activity of the residents of the Lviv urban ecosystem within the green zones is shown in walks, with pets included, mostly on unauthorized trampled trails, in organizing picnics, usually with the burning of fires, sports games and sunbathing and other, however, it is somewhat different depending on the type of green area and its affiliation with the nature reserve. Accordingly, the green areas of the Lviv urban ecosystem are exposed to such environmental effects as trampling of grass, which in turn leads to compaction of soil, compaction of the layer beneath, death of descending plants; collection of individual plants (usually flowers), which reduces the possibility of their self-renewal; mechanical damage to the green planting - a broken branch, kerf or notch on the trunk which cause infection of the trees with diseases and pests; contamination of the territory; burning of the upper layers of soil through unauthorized arrangement of fires, etc. Scientific novelty. Here is described the ecological consequences of the impact of tourist and recreational activities, which are quite large in local terms. Practical importance. It is stated that within the limits of the greenzones of the Lviv urban ecosystem, it is forbidden to damage and destroy trees, grass cover and equipment, consider a camp fire, arrange unauthorized rest places, passage and parking of transport, walk animals. But in order to reduce the negative impact of tourism and recreational activity on the state of the green zones of the urban ecosystem of Lviv, it is also necessary to introduce a system of management of the green zones of the city, which is, to create an interested administration.The wellestablished actions of the administration contribute primarily to the demarcation of the territory of the green areas, as well as to reduce the negative demonstration of recreational use of green areas.

Active Recreation

Natural environment potential encompasses such components as e.g. climate, relief, biota, waterways, all of these significant for the recreational activity carried out in nature. Such activity is increasingly more popular with city dwellers who, encouraged by new lifestyle trends, try to engage in active recreation on weekdays and at weekends. Existing environmental potential in urban areas may determine to a great extent the opportunity and nature of recreational activities of city inhabitants. Szczecin spans across a large area (over 300 km²) and enjoys versatile natural environment, with predominance of water and green areas (25% and 20% respectively). Green areas include forests with great landscape, recreational and specialist values, which allows the citizens (approx. 400 000 inhabitants) to engage in various forms of recreational activities. However, half of this area remains unkempt or not properly maintained which results in concentration of recreational traffic in the other areas, now hosting better leisure facilities though still not sufficient to meet the needs of the city’s population. The accumulation of tourist and recreational infrastructure over a limited area causes an over-concentration of recreational traffic, contributing to excessive exploitation of natural environment (as estimated, capacity norms are being exceeded 15-16 times). At the same time, even though there are several initiatives in operation aimed at integrating Szczecin’s green areas, the city still lacks a coherent, sensible system of developing and using Szczecin’s wooded areas which would benefit the citizens, as well as sustain the ecological balance of its forests. It can be thus concluded that the huge recreational potential of Szczecin’s wooded areas is used only in part. Key words: recreation, natural potential, woodland.

Recently, the number of published works devoted to the processes of synanthropization of fauna, is growing like an avalanche, which indicates the extreme urgency of this theme. In our view, the process of forming devices to coexist with human and the results of his life reflects the general tandency of the modern nature evolution. Urbanization is characteristic for such a specific group of animals like amphibians, the evidence of which are numerous literature data. Many researchers use this group to assess the bioindicative quality of the environment. For this aim a variety of indicators are used: from the cellular level of life of organization up to the species composition of the group in different territories. At the same time, the interpretation of the results is not always comparable for different areas and often have significantly different interpretations by experts. Urban environment, primarily due to the contamination is extremely aggressive to amphibians. As a consequence, the urban populations of amphibians may be a change in the demographic structure, affecting the reproductive ability of the population, the disappearance of the most sensitive species or individuals, resizing animals, the appearance of abnormalities in the development, etc. At the same time play an important amphibians in the ecosystems of cities, and some species in these conditions even feel relatively comfortable. Therefore, it is interesting to understand the mechanisms of self-sustaining populations of amphibians in urban environments. To assess the impact of natural and anthropogenic factors on the development of amphibian populations were used cognitive modeling using the program Vensim PLE. Cognitive map of the model for urban and suburban habitat conditions were the same. The differences concerned the strength of connections between individual factors (migration, fertility, pollution) and their orientation. In general, factors like pollution, parasites, predators had negative impact on the population, reducing its number. The birth rate, food and migration contributed to raising number of individuals. Some of the factors affected on the strength to of each other as well: the majority of the factors affected the structure of the population, had an influence on the fertility. Thanks to it the model reflects the additive effect of complex of factors on the subsequent status of the population. Proposed and analyzed four scenarios differing strength and duration of exposure. In the first scenario, a one-time contamination occurs and not subsequently repeated. The second and third scenario assumes half board contamination, 1 year (2 scenario) and two years (scenario 3). In the fourth scenario, the pollution affected the population of amphibians constantly. In accordance with the results of simulation, much weaker than the natural populations respond to pollution - have them as an intensive population growth and its disappearance at constant pollution is slow. Changes to other parameters of the model showed that this pollution is the decisive factor -only the constant action leads to a lethal outcome for the populations. All other components of the model have a corrective effect on the population dynamics, without changing its underlying trand. In urban areas due to the heavy impact of pollution maintaining the population is only possible thanks to the migration process – the constant replenishment of diminishing micropopulations of natural reserves. This confirms the assumption that the form of existence metapopulations lake frog in the city. In order to maintain the number of amphibians in urban areas at a high level it is necessary to maintain existing migration routes and the creation of new ones. Insular nature of the placement of suitable habitats in urban areas causes the metapopulation structure of the types of urbanists. Therefore, the process of urbanization is much easier for those species whicht are capable of migration in conditions of city. In the initial stages of settling the city micropopulationis formed by selective mortality of the most susceptible individuals to adverse effects. In future, maintaining the categories of individuals is provided mainly due to migration processes metapopulisation form of the species of existence is supported). It should be noted that the changes in the previous levels are always saved in future. In the case of reorganizations of individuals we of morphology can assume the existence of extremely adverse environmental conditions that threaten the extinction of the micropopulations.

Gelendzhik is the resort town, there aren't a lot of industrial enterprises here. The main pollutant is transport. The work purpose is the assessment of a condition of the artificial landings of a pine located along the Federal highway "Don" and landings, which is nearly the sea coast. Researches were conducted to a standard technique of the General vital state (A. S. Bogolyubov). The assessment of a condition of pines was carried out during 6 years: from 2010 to 2015. For carrying out research we used 6 experimental grounds on the Markotkhsky spine and 2 control grounds within the town. We investigated 24 trees on each platform, middle age of the trees were 30 - 40 years. Results. 1. The condition of trees in the pine forests located in immediate proximity with the Federal highway "Don" (No. 1, 2, 3) is unsatisfactory. As even weak influences of the majority of atmospheric gaseous pollutants (sulphurous gas, nitrogen oxides, etc.) give effect of a necrosis and hloroz of pine needles, the condition of pines is connected with technogenic pollution. So near the Federal highway "Don" the air environment is strongly polluted by exhaust gases. Information of 2012 confirm that negative influence of the route on Markotkh's vegetation decreases at reduction of load of the route. 2. On the sites located above on a slope (No. 4,5,6) thanks to remoteness and the wind mode intensity of influence of pollutants is lower and a condition of pines the quite satisfactory. 3. Trees on the sites located near the sea (No. 7,8) are in a good shape. Small deterioration of a state is noted in very droughty years. Conclusion. Results of six years' research show that the condition of the plantings which are in close proximity with the road worsens. It is explained by increase in intensity of the movement on the road, especially during a resort season. Gelendzhik is the city with a good ecological shape, but the damage to environment is already caused. If not to take measures, we can lose a unique part of the nature in the future, recreate it will be impossible. Measures of reduction of negative impact of exhaust gases were offered. Results of researches are transferred to ecological department of the City administration of Gelendzhik.

Historic centers have become first-line tourist destinations. In order to achieve sustainable development, it is essential to get to know the opinions of the host community on the impact of tourism, the positives, as well as the negatives. This paper aims to understand the residents’ opinions and perceptions of destinations as the historic cities. This research looks into the residents’ opinions on the impact of tourism in the historic city of Toledo, Spain. The results of a quantitative survey among 442 residents in the city of Toledo are presented. The study is a revision of the literature and analysis and explanation of an empiric study’s results. Descriptive statistics have been used, as well as factor analysis and non-parametric tests to analyze data. The main results point out that residents have a positive vision of tourism development, rather than negative. The economic importance of tourism and its ability to create jobs stand out. However, they also think that the historic center is being turned into a museum for tourists. Analyzing their opinions according to certain demographic and socioeconomic characteristics, some major differences come up, such as that the inhabitants of residential areas have a more positive opinion than those who live in the historic center. Understanding the perspective of the residents can help the managers and planners of the tourism in the city to play down the potential negative impact of tourism and to achieve support from the host community in regards to tourism.

Trees are essential elements of an urban space. The presence of trees in urban areas is not only appreciated as physical attribute, but beyond this, it serves a fundamental function in balancing and conserving urban ecosystem. Especially in tropical countries like Indonesia which receive high levels of solar radiation, trees contribute to the protection of urban areas from the impact of excessive micro-climatic conditions. But, the presence of trees sometimes resulted in the accidents for the residences because of broken branches and human injuries. This situation leads the city to prepare a tree inventory system, which is beneficial in giving the information about tree conditions and thus the information that would be useful for tree maintenance activities. The tree inventory on application for the city of East Jakarta was built for this purpose, comprising a tree inventory and easy access to the database. The application connects the database source with the GIS map, so that the users could retrieve information for each kind of data.

Using Shanghai F1 as an example, this research seeks to examine the impact of mega-events on host city image from the perspective of international students. Leisure facilities and service were the most positive image impact perceived by the respondents, followed by affective city images as well as opportunities and convenience. International students tended to disagree that F1 would result in any crime and security problems and were unsure about any negative impact on environment and daily life. Some of the image factors were significantly related to intention to work in the city or the willingness to recommend the city.

Freight Vehicles

The impact of freight transport in cities is significant, and as such correct planning and management thereof help reduce their enormous negative impact. Above all, the special large vehicles have a greater impact than the remainder of freight vehicles, so a special attention should be paid to them. The vehicles which supply or pick up large amounts of goods at specific points throughout the city are an example of this type of vehicles. The aim of this paper is to minimize the cost of this freight transport type from a social, economic, and environmental viewpoint. To this effect, an optimization model has been proposed based on bilevel mathematical programming which minimizes the total system costs. City network model data are obtained on the lower level such as vehicle flow and travelling times, which are then used on the upper level to calculate total system costs. The model has been applied to a real case in Santander (Spain), whose final result shows the size and typology of the fleet of vehicles necessary to have the least impact on the city. The greater the vehicles size is (i.e., using fewer trucks), the less the cost of the freight transport is.
