The characteristic feature of real estate market is local character, which marks that the conditionings of local market have very large influence on housing prices and dynamics of their changes. The study of changes housing prices as a result of outflow of time should, therefore to take into account both general trend and spatial differentiation, resulting with values of localization. The paper presents possibility of use geographically weighted regression to analysis of dynamics of changes housing prices on the area of Olsztyn in years 2003–2009. The simple global model in this aim was built for whole area of analysis and then the models of geographically weighted regression taking into account the spatial dependences weights. The conducted analysis confirmed the usefulness of the GWR method, as tool of spatial analysis of real estate market.

The paper presents the question of the co-existance of the palace in Sztynort and the surrounding park in their natural setting, on the shore of Sztynorckie Lake. The contemporary scenic relations of the landscape interior composed of the lake and the historic building have been lost due to the many years of transformations, often chaotic ones, in the analysed area. The present-day condition of the scenic relations and the manner in which the valuable palace is exposed today have been diagnosed. The negative consequences of the transformation of the shores of Sztynorckie Lake for the landscape values of this special place have been discussed. Some possible actions to be undertaken in order to protect the landscape values of the palace and its grounds have been suggested.

In this paper we have shown the result of 5-years experiment related to direction of floristic composition of sward, designed and commercial mixtures which can be sowing on recreational lawns in Masurian Lakeland. Exact experiment microfields founded on 14 May 1998 with split-plot method, three times repeted, on antropogenic soil, formed from loamy sand. Floristic composition was estimated on a basis of botanical and weighting analyses every year in autumn. It was shown that species composition of mixtures on recreational lawns changed dynamically. In the first year of experiment Lolium perenne (leadnig species) was dominated species of sward but after frosty winter has been withdrawn. The most durable were Festuca rubra (leadnig species) and Poa pratensis (co-component). The other co-component of mixtures: Festuca ovina, Festuca heterophylla, and Agrostis capillaris were in sward in small part. Among different variants the most profitable floristic composition had mixture no 11: Poa pratensis Alicja, Festuca rubra Nimba, Festuca rubra Adio, Agrostis capillaris Igeka and commercial mixture Johnson “Wimbledon”.

During the years 2001–2004, the yield and morphology of fruit of 4 Belarus varieties of common sea buckhorn: Podarok Sadu, Botaniczeskaja, Otradnaja, Trofimowskaja and the Baltic form that was not a variety obtained from local seeds were investigated in the Experimental Garden of the University of Warmia and Mazury in Olsztyn. The bushes used for the investigation were five years old. On the basis of the conducted tests it was established that the yield, mass, length and width of the fruit of cultivated varieties of common sea buckhorn are related to the individual characteristics and complex of specific climate-soil conditions. The climate – soil conditions of Olsztyn were favorable for development of Belarus varieties of common sea buckhorn. The maximum yield was obtained in 2003 when the highest yields were produced by Otrodnaja variety (20.07 kg per bush) and Podarok Sadu variety (17.07 kg per bush). In 2004 the yields of fruit were the lowest (average for the varieties 1.37 kg per bush).

This article presents the functions of transport networks. These mainly include service, transfer, integration and acceleration functions. Management of networks fulfilling so many functions requires an appropriate information base. The article examines which information and database systems are used to support decision-making while managing national and provincial roads. Each of the managers gathers similar data, although their scopes differ. GIS technology makes it possible to visualize selected data and phenomena. The possibility of obtaining information on the spatial location of road network attributes allows gathering of thematic geo-information systems, which help in making decisions related to transport network maintenance and management.

The development and expansion of ecotourism can be enhanced considerably by attractive landscape areas situated in close neighbourhood of big towns and cities as exemplified by Wierzenica and its surroundings situated near Poznań. The village is associated with the patron of the Poznań Agricultural University. The study presents an assessment of the natural value of meadow communities which are found in the Główna River valley near Wierzenica. In addition, on the basis of literature data, floristic peculiarities of the nearby forests which form part of the Zielonka Primeval Forest were described. When evaluating the cultural significance of this region, the authors relied on their own observations, information obtained from interviews with inhabitants of the village and literature data. Moraine hillocks, picturesque small valleys, ditches and ravines as well as beautiful tree alleys harmonise perfectly with the existing monuments as well as the preserved original design of the village. The natural peculiarities of the area include: common oak trees (Quercus robur) with 500–630 cm circumference, a pine tree ravine, white poplar (Populus alba), while the occurring diversified site conditions contribute to the development of meadow communities of high index of floristic variation ranging from 1.96 to 3.51. Despite the fact that nearly 98% of plants were classified as plants of mezzohemorobe and euhemorobe sites and the synanthropisation index reached 78.6%, the natural and scenic as well as the cultural value of the Główna River valley allow and encourage various forms of ecotourism.

Biological diversity decreases as a result of human activities. Progressing degradation of the natural environment made the EU member states cooperate in order to finance projects aimed at protecting the most valauble areas. EU funds enable to pursue economic and social cohesion policy, as well as to restructure and modernize national economies.These funds are also used for the purposes of agricultural landscape planning and protection. These are, among others, the European Agriculture Guidance and Guarantee Fund (EAGGF), Sector Operational Program for Restructuring and Modernization of the Food Sector and Rural Development, Integrated Operational Regional Development Program,Cohesion Fund and Community Initiative INTERREG III and LIFE Fund supporting a network of protected areas Nature 2000. EAGGF is based upon the Sector Operational Program and Rural Development Plan. One of the instruments of the Rural Development Plan is the National Agricultural and Environmental Program, composed of agroenvironmental packages. Agricultural and Environmental Programs are important tools for implementing EU directives in the field of nature protection.

One of the most outstanding European landscape architects of the 19th century – Peter Joseph Lenné (1789–1866), during his 50-year long professional activity aimed at combining all elements of landscape. This study presents the landscape planning project, improving the attractiveness of agricultural land, designed by Lenné for the Radaczewo estate (the Zachodniopomorskie province). The design prepared in 1825 covered the area of almost 1000 ha. The area comprised arable land, gardens, pastures, tree plantings, water bodies, etc. –structures and elements which merge and form a unique mosaic in the local landscape. Attention is drawn here to the irregular outlines of individual fields and crops – so different from the contemporary, rectangular shapes and divisions. Advantages and disadvantages of the solutions adopted in Radaczewo, along with an analysis of the preservation status of this object constituted the subject of this study.

Abstract

The paper presents definitions of landscape according to different criteria. An attempt was also made at characterizing the agricultural landscape considering its basic components, i.e. cultivated fields and green use land. The major threats to functioning of contemporary agriculture and areas of conflict between development and protection of agricultural landscape were identified. Additionally, a proposal for systemic and local solutions aimed at preventing of liquidating those threats was presented. It was concluded that landscape formed by agriculture is characterized by spatial variability resulting from the form of use and differentiated contents of biocenoses, which in turn results in seasonal differences in color and height depending on the species of crop and its development phase. Additionally it varies and is volatile over time; colorful and interesting from lavish development of plants in the spring until harvest and later generally monotonous, gray and unattractive.

This paper investigates the use of Rough Set Theory for supplementing databases on the real estate market. The proposed simplified procedure may pose an alternative for statistical methods, and it produces reliable results over a short period of time. The procedure of supplementing incomplete data has been developed based on the principles of Rough Set Theory and the valued tolerance relation. The above combination produces optimal results because it accounts for varied methods of entering property attributes.

Considerable area of riparian forests in the middle valley of the Warta River (nearby Radzewo village) was transformed to meadows and pastures. Some tree species, connected with those sites, i.e. black and white poplars, were cut off, died or are dying. The key conditions responsible for natural regeneration of this two species undergo rapid changes as a result of disturbances in flooding water flow related to establishment (in 1986) of retention reservoir in Jeziorsko and artificial draining of this area. The ecological niche, previously suitably for poplars is filled up by invasive North American species of Acer negundo (boxelder or ashleaf maple). The seeds of this maple were probably brought with floods from nearby places. Mass appearance of young generations of Acer negundo is a result of easy generative propagation of this species. The last living female trees of black poplar are now under threat and only protection ex situ of seeds (stored in traditional way or in liquid nitrogen) will make possible to regenerate this population in the future.
A village and former manor house and park establishments in Szymonowo are located 9 km south of Małdyty, in the vicinity of Lake Ruda Woda. They cover a total area of 6.32 ha. The manor house, built in the 19th century, is situated in the park. Until 1928 the whole estate was owned by Count Finck von Finckenstein. In the years 1945 – 1946 the estate in Szymonowo was taken over by the State and a children’s home was established there. The shape of the landscape park resembles an equilateral triangle. Main alleys run from the manor house towards two ponds and along the line connecting both ponds on the western side. As concerns the former establishments, the park architecture and some alleys have survived until today. An old-growth forest, dominated by Acer platanoides L., Ulmus laevis L., Fraxinus excelsior L., Tilia cordata Mill., Picea abies L. Karst, is also well-preserved. Near the manor house, to the north-west, there are monument oak-trees (Quercus robur L.) whose breast height is 380 to 450 cm. Along the western boundary of the park there are tree lines composed mainly of Norway spruces and small-leaved limes. Only some of the walkways have survived.
