Green areas planning is an example of the man's activities that should not be considered apart from the other activities and disciplines, dealing with the man's environmental management. Their development is directly proportional to the evolution of civilization as well as the settlement development. The relationships between green areas planning and ecology, architecture, town planning, spatial planning and economy seem to be abvious at the present time. According to research results, incomparable or false input data cause the main barriers and difficulties of green areas planning and design even at the initial stage. Green areas development performs on two linked planes: theory and practice. A study tool is their common denominator and makes possible an adequate description of cultural landscape as well as its projection and modelling. Terms used for the facts description must strictly correspond with a nature of these facts, and should be gradually verified together with any changes of the facts. Such a verification has to influence the identification and evaluation of the green areas quality. Strictly defined terms can be conductive to green areas development both an the theoretical and practical planes. Polarization of the green areas evaluation, lack of one common definition and understanding of a term green areas in the Polish law or polarization of the attitudes towards town planning paradigm (green city, compact city) have brought to light a wide need of solving this dilemma. A term structure is used in different scientific descriptions or spatial studies and plans, and has a minimum of three meanings; firstly - as a process of urban landscape creation, secondly - as a method of urban landscape description, thirdly - as a method of urban landscape modeling. Structuralization in the meanings presented above can be used in the process of green areas planning and development. Crucial tasks of the green areas structuralization are listed below: identifying directions for perceiving the existing green areas, elaborating a principle of green areas modeling, contributing to a green areas sustainable development. A theoretical base of structuralization has its roots in different theories like systems theory, changes theory or classification theory considered in the light of urbanization theory as well as in the knowledge of green areas development, worked out up to now. A group of structuralization methods consists of: classification, taxonomy, evaluation, delimitation, qualifications, stratifications, SWOT and others. Thanks to theoretical and methodical principles of structuralization the green areas composition can be examined. A structure of green areas in the urban landscape planning and design can be considered in two ways: firstly - as a theoretical construction and mental images, secondly - as a physical state of existing greenstructure. These theoretical concepts and ideas are used for green areas identification. A complex inventory of existing green areas should precede their identification in urban area and structuralization seems to be very useful in this process. Structuralization has its own order the facts cognition: on the strategic stage, on the operational stage, on the implementation stage. The main goal of this work is to formulate theoretical premises that can positively influence urban landscape through improving green areas planning and design in the Polish physical and local planning. Studies of the green areas structuralization have shown some new possibilites: more precise the green areas identification, elaboration of a standard for studies of green areas, assimilation of two terms pattern and system as a different way of green areas description. Green areas understood as a typical system of closed, semi-closed and open cities can be considered as an indicator of the intensity of urban landscape changes. Thus green areas can play role as a specific element of a defensive system that protects the urban landscape harmony against an.
