The aim of this paper is to identify and describe the landscape and geochemical zones on the southern slopes of Kilimanjaro. Characterization of individual zones was carried out based on a literature synthesis and author own study. The article contains description of four main zones and eight subzones. The Kilimanjaro’s altitudinal vegetation zones...

W latach 2006 i 2018 zostały przeprowadzone badania właściwości fizycznych i chemicznych poziomów próchnicznych gleb Pola Mokotowskiego w Warszawie. Wykazały one utrzymującą się zasobność w składniki odżywcze oraz optymalne warunki retencji wody dostępnej dla roślin. Pogorszeniu uległa struktura i układ gleby, w efekcie czego doszło do zaburzenia w...

Resumen: Los servicios ecosistémicos en las ciudades y áreas suburbanas circundantes son uno de los principales factores que garantizan la calidad de vida. El objetivo de la investigación fue analizar el tipo de uso del suelo seleccionado (bosque, área urbana verde), servicios ecosistémicos seleccionados (regulación del clima, recreación) en 27 ciu...

The aim of this study was to evaluate the temporal and spatial land use and ecosystem services changes in the area of urban sprawl on a local scale. For the study a suburban area of Warsaw was selected, which is bordered by a large forest complex-Kampinos Forest, enshrined in Kampinos National Park. In the first stage of the study, change in land c...

Ecosystem services (ES) in cities and surrounding suburban areas are one of the major factors which guarantee quality of life. Most studies directly referring to urban ecosystem services are conducted on a local scale or for selected cities. There are few studies which focus on temporal changes of the provision of ecosystem services across a large...

Przedmiotem badań była ocena sekwestracji węgla, jako popularnego wskaźnika regulacyjnych świadczeń ekosystemowych, przy użyciu dwóch baz pokrycia terenu – Urban Atlas (UA) i Corine Land Cover (CLC). Badania objęły zachodnią strefę miejską i podmiejską Warszawy z fragmentem Kampinoskiego Park Narodowe- go (gminy Stare Babice, Izabelin, Łomianki i d...

This paper discusses recreational use of protected land with the example of Las Kabacki, a forest located in the southern part of Warsaw, in the vicinity of the district of Ursynów. The area has been excluded from traditional forest cultivation since 1938. From 1980 onwards it has enjoyed the status of a reserve due to its natural resources and sce...

The purpose of this study is to present opportunities for using landscape metrics to evaluate geodiversity on individual landscape levels. The research area is located to the west of the Płock Urban and Industrial Agglomeration in Poland. Within this area, hierarchically organized regional units were delimited (Richling, Malinowska, Szumacher 2013)...

The concept of catena in landscape surveys is used to demonstrate the surroundings of landscape units, their vertical structure and inter-unit processes, as well as the mosaic nature of the landscape. Furthermore, it reflects the structural and functional heterogeneity of the surveyed area, at the same time indicating types of links between landsca...

The subordinated position of soil in the geosystem allows it to be used as an indicator of the landscape balance. Examples where soil plays such an indicative role are presented in this paper. The theory of the “geochemical landscape” has been used as the theoretical-methodological basis. Soil properties indicating direction, intensity and quality...

The main objective of this paper is to represent the hierarchical structure of an environment by using two concepts: typology and regionalization. The Płock Region (1,766.95 sq. km) and transect crossing this area (796.2 sq. km) is the research location. It was divided into 710 individual landscape units (319 in the transect border). The existing p...

Visitor's access to understorey vegetation in park forest stands results in the impoverishment of plant species composition and a reduction in habitat quality. The phenomenon of biotic homogenisation is typical in urban landscapes, but it can proceed differently depending on the scale, a detail that has not been observed in previous studies. This r...

Functions of Urban Greenspace and Ecosystem Services The concept of ecosystems services has become an important model for linking the functions of ecosystems to human welfare. The aim of this paper is to identify ecosystem services generated by green areas within the urban area, classify and value them. "Ecosystem services" refers to components of...

The concept of ecosystems services has become an important model for linking the functions of ecosystems to human welfare The aim of this paper is to identify ecosystem services generated by green areas within the urban area, classify and value them. "Ecosystem services" refers to components of nature, directly enjoyed, consumed, or used to yield h...

The goal of this paper is to present interdisciplinary environmental studies in urban park. Simple measures are proposed here for evaluating the status of vegetation and its habitat. When systematically applied, these measures could be a basis for sustainable management of the park greenery. Studies performed in Skaryszewski Park in Warsaw are as a...

The paper presents the results of interdisciplinary workshop concerning space perception, carried out in Warsaw and the Tatra Mountains in 2006. The research had qualitative character. In urban research indirect perception was under study, whereas mountain part involved both direct and indirect perception. The main aims of the workshop were to: (1)...

The goal of this paper is to present European parks form the point of view of their natural environment and ecological functions which they fulfill in the city. Parks situated in valley landscapes have been used as the object of study, since these types of parks predominate in Europe. These are: Hyde Park in London, Clara Zetkin Park in Leipzig, Ti...

The goal of the study was to identify and estimate the ecological functions of urban parks using the geoecological methods. In the work were analysed: dependence between parks' origin, position in the city and natural landscape's components. The Hyde Park in London, Tiergarten in Berlin, Clara Zetkin Park in Leipzig and Łazienki Królewskie in Warsa...

Observations carried out within the area of the Łazienki Park in Warsaw indicate the existence of the following regularities: - at the mesoscale: natural exchange of matter between the components of landscape and its spatial units has been preserved; this means that the pollution deposited on the autonomous surface is a constant threat to the super...
