The Dzierżązna and Ciosenka (Dzierżązna's tributary) drainage basins are characterised by significant variety of land use forms. The southern part of the basin has large proportion of build-up areas, with single-family and single-storey housing prevailing on the outskirts o[ Zgierz. The morphologically diversified Smardzew level is dominated by forest. North of the forest, where more fertile brown soils spread, agricultural land dominates. The middle part of the study area, between Lućmierz and Emilia and Kolonia Jeżewo, with large proportions of aeolian and glaciof1uvial sand, is covered by [orest and agricultural land. Recreational use o[ the forest, with many allotment gardens, is typical [or this area. Also extensive wastelands found here confirm little productivity potential of the sandy soils. The northern part of the basin has a mixed arable-meadow-forest land use, resulting from large diversity of edaphic and moisture conditions. The map of forms and directions of land use at a scale of 1:10 000 based on fieldwork carried out in July 1998 (Fig. l) has enabled to recognise the present state of management o[ the area and processes typical for the suburban area o[ Łódź. The detailed picture o[ land use can serve as a basis for estimation of CN parameter and for evaluation of potential retention of the Dzierżązna drainage basin with the SCS method.

W artykule zamieszczono i opisano mapę form i kierunków użytkowania ziemi w zlewni Dzicrżąznej, wykonaną na podstawie kartowania terenowego przeprowadzonego w lipcu 1998 r. oraz przedstawiono aspekty hydrologicme wynikające z aktualnego zagospodarowania terenu badań.
Głównym celem artykułu była ocena atrakcyjności wizualnej krajobrazu fragmentu doliny Mrogi wraz z jej najbliższym sąsiedztwem w granicach administracyjnych gminy Dmosin. Oceny tej dokonano przy zastosowaniu metody fotograficznej Cymermana i Hopfera (1988), zmodyfikowanej przez Hajnrych (2006). Metoda polegała na ocenie 426 fotografii wykonanych z 72 stanowisk dokumentacyjnych, zlokalizowanych wzdłuż doliny rzeki Mrogi. Na podstawie wyników oceny wydzielono pięć klas atrakcyjności wizualnej krajobrazu. Największy udział mają tereny o niewielkiej i przeciętnej atrakcyjności wizualnej, a obszarów o dużej i bardzo dużej atrakcyjności jest niewiele. Do artykułu dołączono opracowaną na podstawie badań mapę atrakcyjności wizualnej krajobrazu.

The main aim of this paper was an evaluation of the visual attractiveness of landscape of the Mroga valley and its surroundings in the administrative borders of the Dmosin commune. That evaluation was made by a photographic method of Cymerman and Hopfer (1988), modified by Hajnrych (2006). The method was based on an evaluation of 426 photographs taken at the 72 documentation sites located along the valley of Mroga river valley. On the basis of results of the assessment, it established five classes of visual attractiveness of the landscape were established, of which the largest share included areas of low and average visual attractiveness. Areas of high and very high visual attractiveness were few. A map of visual attractiveness of the landscape was made.
After Poland joins the European Union Polish agriculture will face significant structural changes, with the consequent loss of biological diversity. With the aim of taking actions to prevent the degradation of agricultural landscape, in 2002 a common research project "Biodiversity of agricultural landscape of Central Poland and its expected changes in connection with the transformations of agrarian structure after Polish accession to the EU" was started by an international team from the University of Łódź and Justus Liebig University of Giessen, Germany. The principal aim of the research is to assess the current state, expected future changes and threats to biodiversity in agricultural areas of Central Poland. The issue of the protection of agricultural landscapes accords "The national strategy for conservation and sustainable use of biodiversity" announced by the Ministry of the Environment. The investigation will include the following tasks: - to determine the landscape structure of the study area - delimitation of morpholithohydrotopes; - to describe the current land use; - to analyse the floristic diversity of the studied habitats; - to determine the relation of landscape structure, land use and biodiversity; - to study the importance of linear structures in agricultural landscape for floristic biodiversity; - to distinguish areas suitable for the implementation of various protecting measures. The results of investigations will enable to define types of areas with the highest natural values in agricultural landscape, which should be designated as protected areas or covered by agri-environmental schemes. Conclusions from implementation of the new investigation procedure can be adopted for spatial planning at local and regional levels. The results can become a basis for the development of detailed indications of directions of agriculturalland management so that traditional agrarian structure would be preserved in the areas with the highest biological diversity. Adverse changes of agrarian structure and biodiversity that took place in Germany call for urgent implementation of the research project in Central Poland with the aim of taking actions to prevent the degradation of Polish agricultural landscape.

W związku z przewidywanymi zmianami w strukturze własnościowej, obszarowej, kierunków użytkowania ziemi, jakie nastąpią w rolnictwie po wejściu do Unii Europejskiej, Autorzy przedstawiają projekt prac badawczych dotyczących różnorodności biologicznej obszarów rolniczych Polski Środkowej. W Artykule zostały przedstawione cele i proponowane metody badań, charakterystyki trzech wybranych obszarów reprezentatywnych, czynniki wpływające na różnorodność biologiczną, dokonano wstępnej oceny stanu bioróżnorodności oraz wyrażono opinie na temat możliwości ochrony terenów rolniczych.
