Item Dynamika zmian powierzchni leśnych na terenie gminy Suchy Las w okresie 1940-2000(Wydawnictwo Poznańskiego Towarzystwa Przyjaciół Nauk, 2007) Macias, Andrzej; Michalczyk, AleksandraThe article presents the results of a research on the dynamics of change in the woodland area of Suchy Las commune in the 1940–2000 period. The commune was chosen because of its interesting spatial division resulting from the existence of the Biedrusko military ground within its limits. A comparison was made of the level of afforestation of the commune as provided by its topographic maps from the years 1940, 1960, 1980, and 2000. An analysis was also made of the number of woodland complexes as well as the extent of deforestation and afforestation. Throughout the study period the commune was divided into two characteristic spatial units. The lasting separation of functions and totally different land-use patterns has made them develop radically dissimilar landscapes. Over the study period the commune’s total woodland area grew from 23.75 ha to 43.5 ha, but in the military ground it increased from 24.45 ha to 42.04 ha, while beyond it there was a decline from 2.3 ha to 1.46 ha. The military ground in Suchy Las commune greatly restricts the possible uses of land there and reduces the area of potential investment by more than a half, but on the other hand such an extensive green space (the woodiness index for this part of the commune equals 36.1%) is its great natural wealth, enhances its landscape attractiveness, and facilitates natural vegetation growth. By contrast, the area outside the military ground features very sparse woodland (the woodiness index for this part of the commune is a mere 1.2%), which is due to the necessary concentration of many functions in a small area. The economic development of the commune may lead to further loss of woodland in this part.Item Działalność naukowo-dydaktyczna Prof. UAM dr hab.

Adama Mickiewicza, 2010) Macias, Andrzej; Dryjer, MartaForests on the urban areas are of a great importance for the biodiversity of this territory. Moreover, they play numerous functions in the environment and constitute, at present, on important element of the ecological urban system. Nevertheless, the changes of the forest areas in the city of Poznań have never been discussed so far. This article presents the results of research of the changes of forest areas in Poznań within the administrative borders of Poznań in 2004. It was performed for the period 1830–2004 for six selected moments in which topographic maps of this area were prepared i.e. 1830, 1888, 1940, 1960, 1979 and 2004 During this period forest area increased by 2367 ha. The effect of numerous afforestations and deforestations is that forest area which was not subject to these treatments from 1830 to 2004 constitutes only 481 ha (14.6% of forest areas of Poznań). Four periods of dynamics of changes of forest areas were distinguished. During the last one, taking place presently, forest area has decreased slightly. In the case of Poznań, maintaining forests is significant from the point of view of their importance not only for functioning of green wedges but also the whole environment of this city. Therefore, one of the directions of spatial development of the city of Poznań should be maintaining and increasing forest areas as the element of the implementation of sustainable development principles.Item Wpływ człowieka na tereny biologicznie czynne w mieście na przykładzie klinów zieleni w Poznaniu(Wydawnictwo Poznańskiego Towarzystwa Przyjaciół Nauk, 2016) Witczak, Łukasz; Macias, AndrzejThe purpose of this paper is to identify the factors of destruction of the urban green system as exemplified by the green areas in the city of Poznan. The conclusions are drawn with respect to an analysis of the land use changes and field work. The objective of this research was to identify poor practices in urban development and suggest a solution to alleviate the negative changes.
