Ważnym problemem w planowaniu przestrzennym jest kształtowanie ekologicznego systemu miasta. Funkcje ekologiczne przypisywano terenom otwartym, przeciwstawiając je terenom zabudowanym. Stwierdza się jednak, że niektóre typy terenów z zabudowę jednorodzinną wykazują wyższe walory ekologiczne od obszarów zaliczanych do terenów otwartych. Mogą więc one stanowić element systemu ekologicznego miasta. Warunkiem wysokich walorów obszarów z zabudową jednorodzinną jest duża wielkość działki i właściwy sposób ich zagospodarowania, co może być określone w planie miejscowym.

Ecological functions of the town are usually attributed to the so called green areas as opposed to the housing areas. However, the ecological values of many types of open areas are in reality not so high. Simultaneously, there are many data pointing out to the high values of areas built up with onefamily housing, at any rate for some of their types. To appraise the ecological values, the appraisal of the vegetation values may be used wich is an index of the state of other environmental elements, creates these elements and has its share in creation of a biotope for the fauna. Essential features of the vegetation cover _ apart from the size of the biomass, abundance of species and share of native species is the differentiation of vertical structure (measured by means of the number of layers) and the presence of high trees. From the point of view of creating the microclimate, an essential feature of each type of the area is the character of the active surface (surface exposed to the sun's rays), and particularly the relation of the articifial surfaces to the natural ones. Within the areas of onefamily housing, seven types of the ecological system have been distinguished and called landscapevegetation complexes. In the present research, the areas included to three the most frequent types (onefamily housing on forest plots, on large building plots of suburban character and on small building plots) are compared with some types of so called open areas. The enclosed drawing shows the character of the active surface in various types of the landscape-vegetation complexes. In the areas of onefamily housing, this character is frequently more natural than in some types of open areas. A similar reglarity has been stated in the analysis of the abundance of the vertical structure of vegetation and of the geometrization degree of the landscape. This may be an indication that some types of the onefamily housing may be a valuable element of the ecological system of the town. From this point of view, the size of building plots and the way of their developing is of essential importance. These both features may be designated in the plan of physical development.

Kwidzyn is one of the first towns in Poland to develop a comprehensive and long-term strategy of sustainable development based on Agenda 21. It has been translated into the creation of the concept of the management of the ecological system of the town. Such a system maintains the ecological balance, enhances the structure of the natural environment, diversifies the landscape and affects the life quality of local population. The article summarizes the conceptual design of the system.

Kwidzyn jest jednym z pierwszych miast w Polsce, które opracowało wielowątkową i długofalową strategię zrównoważonego rozwoju, nawiązującą do Agendy 21. Szło o stworzenie koncepcji zagospodarowania systemu ekologicznego miasta. System taki warunkuje utrzymanie równowagi ekologicznej, wzbogaca strukturę środowiska przyrodniczego, urozmaica krajobraz oraz decyduje o jakości życia mieszkańców. Artykuł w skrócie opisuje opracowanie projektowe systemu.

The article presents an overview of selected approaches to the functioning of the natural environment in the city, particularly in the areas of urban greenery , in the context of its utility and value to humans. Starting from the concepts of ecological functions and the potential of natural environment, it indicates the significance of the concept of ecosystem services and the possibilities for its application. The author presents the latter approach as the most comprehensive and taking into account the economic value of natural resources. Some practical conclusions related to the possible applications of the ecosystem services concept in managing the sustainable development of the city are also presented.

Healthy Cities Program was introduced by the World Health Organisation to implement the Health to everybody scheme on the local level. The program aims to improve urban environmental conditions and the health of city-dwellers. The Polish network of healthy cities was created in 1991, and it was incorporated in 1993. It now comprises 38 cities (including Cracow, Szczecin and Wrocław; Warsaw is not a member).

Program „Zdrowe miasta” został wprowadzony przez Światową Organizację Zdrowia w celu realizacji na poziomie lokalnym planu „Zdrowie dla wszystkich”. Ideą programu jest dążenie do poprawy warunków środowiskowych w mieście oraz stanu zdrowotnego mieszkańców. Polska sieć zdrowych miast powstała w 1991 r., od 1993 jest Stowarzyszeniem Zdrowych miast Polskich, posiadającym osobowość prawną. Obecnie liczy 38 miast (m.in. Kraków, Szczecin, Wrocław; Warszawa nie należy).

The article presents a significance of the evaluation of urban trees and benefits of ecosystem services gained from the presence of trees in cities. There was discussed a historical outline of implementing new methods of trees evaluation from cities of each continent and Poland, the country where already 40 years ago has been used a term „infrastructure” with a reference to the natural environment. It underlines also the importance of know-how development in monetary value of multiple utilities generated by trees when it comes to temperature regulation, carbon dioxide absorption, atmospheric air purification, reducing the flow of rain water and other benefits from shaping ecological education and stimulating grassroots initiatives in protecting and growing trees in urban areas. In the article were analyzed the differences between polish term „to make a charge” for removing trees and the term „trees evaluation” which is a tool used abroad to protect urban trees.
