In den Jahren 1941 bis 1942 während des Aufenthaltes im Riesengebirge malte Otto Dix 12 Landschaftsbilder und 8 Gemälde mit religiösen Sujets. Bereits zum ersten Mal erscheint im Schaffen des Künstlers eine dichte Gruppe von Werken, deren Leitmotiv alt- und neutestamentliche vor der realistisch dargestellten, einfach zu erkennenden Landschaft platzierte Szenen sind. Durch die deutliche Stilisierung zu niederländischen und deutschen Meistern um die Wende vom 15. zum 16. Jahrhundert und zu deutschen Romantikern gehören diese Bilder zu den konventionellsten, traditionellsten und monumentalsten Gemälden des Künstlers. Ihr Erscheinen in dem bisher skandalisierenden und bilderstürmerischen Œuvre des Schöpfers löst bis heute Kontroversen und unversöhnliche Auseinandersetzungen zwischen Forschern seines Schaffens aus. Dieser Konflikt oszilliert um die Frage, ob diese Bilder ein Versuch des Künstlers waren, sich in die offizielle Nazi-Politik einzufügen oder ganz im Gegenteil einen Widerstand dagegen ausdrückten.
Na podstawie obserwacji terenowych oraz analizy materiałów archiwalnych dokonano próby ukazania wpływu elementów środowiskowych i społecznych na przekształcenia krajobrazu dolinnego Jedlicy. Wskazano za czasowe i przestrzenne zmiany wywołane działalnością przemysłową i usługową, które w istotny sposób decydują o wartościach krajobrazu kulturowego dolin sudeckich. Elementy kulturowe, historyczne oraz przemysłowe dokumentują i symbolizują przeszłość gospodarczą Karkonoszy. Obecnie istotnym kierunkiem przekształceń krajobrazu dolinnego regionu sudeckiego jest działalność turystyczno-rekreacyjna, która pozytywnie wpływa na estetykę oraz jego ochronę.

On the basis of field observation and analysis of archival materials the influence of environmental and social factors on transformation of the valley landscape of Jedlica River was presented. The study indicated time and spatial changes caused by both industrial and business activities rendering significantly the values of cultural landscape of Sudety Mountains Valleys. Cultural, historical and industrial elements attest and symbolize economical past of Karkonosze Mountains. At present, tourist and recreation activities, which influence the aesthetics and environmental protection of the Sudety Mountains Valleys, determine important direction of landscape transformation in this region.
Based on results of the bryofloristic investigations carried out in 2006 along tourist roads and around mountain chalets the problem of bryophyte response to the tourist utilization of the summit region of Karkonosze Mts is discussed here. The hypothesis that introduction of cement as building material might have caused the income and spread of subneutral or basiphilous ruderal species in that naturally acidic region was formulated and tested. In result 45 species were found, of which the majority do not occur in natural sites in the Karkonosze Mts. Among them 20 species are convinced to be highly hemerophilous. Most of the found species were eurytopic, only 14 prefered subneutral or basic substrata. Many of them produced sporogonia, what indicates high reproduction potential. It seems that the phenomenon of synanthropisation is limited mainly to places in which cement (as mortar or concrete) has been used. The list of bryophytes found around all the anthropogenic sites and along the tourist roads in the summit region of Polish part of the massif with brief characteristics of their ecological preferences has been included.
Based on geographical and ecological analysis of the present moss flora occurring in two contiguous glacial cirques Śnieżne Kotły (Western Karkonosze Mts.), the occurrence of 20 species representing arctic-alpine and subarctic-subalpine elements is discussed. The majority of (sub)arctic- (sub)alpine elements (70%) occurred sporadically or very rarely (no more than 5 records), which indicates their general threat. Nine historically recorded species of these geographic elements could not be retrieved during the recent survey, however four of the recently found species have not been found during the systematic survey of historical sites on the Czech, southern, side of Karkonosze Mts. This proves that the northern localization of Śnieżne Kotły cirques favours the survival of relict species. The question of relictness with respect to the Düll's phytogeographical characterization is discussed; only in ten of the (sub)arctic- (sub)alpine species the relict character could be considered as granted due to their present distribution range. The full list of the Śnieżne Kotły present moss flora with the brief characteristics of their ecological distribution has been included, first such attempt since 1930.
The expansion of Calamagrostis villosa into Nardo-Caricion rigidae grasslands has been recor-ded in the Giant Mountains over the last few decades. The grasslands above the upper tree line were used for cattle grazing and haymaking practices for at least 300 years and the expansion of C. villosa has been recorded after the cessation of this management. The response of the C. villosa stands to mowing and nitrogen fertilization was studied in an experiment over a two- year period. Mowing resulted in the fast decrease of C. villosa coverage, canopy height and biomass production. The fertilization (30 kg N-ha-1 per year) was not able to compensate for the biomass production of mown plots. On the other hand, fertilization resulted in only a slight increase in biomass production in non-mowed plots. The number of C. villosa shoots decreased rapidly under mowing, was constant under mowing combined with fertilization, and increased in the fertilized plots. The fast negative reaction of C. villosa to mowing probably indicates its high sensitivity to defoliation and nutrient removal. Its expansion seems to be the long-term reaction of Nardus stricta dominated grasslands to the cessation of defoliation practices. Its expansion can also be supported by nitrogen deposition. Obtained results, with regard to defoliation sensitivity, probably indicate the quick reduction of C. villosa in agriculturally exploited grasslands above the upper tree line over the last few centuries.

W Karkonoszach w ostatnich dziesięcioleciach zanotowano rozprzestrzenianie się Calamagrostis villosa na pastwiskach z Nardo-Caricion rigidae. Pastwiska powyżej górnej granicy lasu używano tam do wypasu bydła i sporządzania siana przez co najmniej 300 ostatnich lat, a ekspansję C. villosa stwierdzono po zaprzestaniu tych praktyk. Koszenie powodowało szybkie zmniejszanie się pokrywy C. viliosa, wysokości porostu i produkcji biomasy. Nawożenie w wysokości 30 kg Nxha-1 rocznie nie kompensowało produkcji biomasy w koszonych roślinach. 2 drugiej strony nawożenie powodowało jedynie niewielki wzrost produkcji biomasy nie koszonych roślin. Liczba młodych pędów C. villosa spadała gwałtownie na poletkach koszonych, nie zmieniała się na poletkach koszonych i nawożonych i rosła na poletkach tylko nawożonych. Silnie negatywna reakcja C. villosa na koszenie oznacza prawdopodobnie jej wysoką wrażliwość na defoliację i ubytek składników pokarmowych. Jej ekspansja wydaje się być długofalową reakcją pastwisk z dominacją Nardus stricta na ustanie praktyk defoliacji. Ekspansja ta może być podtrzymywana przez odkładanie się azotu. Uzyskane wyniki odnośnie wrażliwości na defoliację wskazują na szybkie zanikanie C. villosa na pastwiskach powyżej górnej granicy lasu użytkowanych rolniczo przez kilka ostatnich stuleci.
Stężenia nadtlenku wodoru w powietrzu w Karkonoszach mierzono równolegle przy użyciu dwóch technik pomiarowych: fluorescencyjnej i chemiluminescencyjnej. Rejestrowane koncentracje były niższe od 2,55ug/m3, a najwyższe wartości obserwowano w godzinach nocnych. Zmierzone stężenia H2O2 mieściły się w granicach stężeń notowanych w innych górskich częściach Europy.

Hydrogen peroxide concentration in the air over the Karkonosze Mountains, Poland were measured using both the fluorescence method and the luminol chemiluminescence technique. Concentrations of hydrogen peroxide in the air, ranged from the detection limit to 2,55um/m3 with the maximum levels being observed at nights. The H2O2 concentrations are comparable with values measured in ambient air at other European mountainous sites.
An Oligocene basaltoid (basanite), unique in terms of its morphology, geology and biology, located in Mały Kocioł Śnieżny in the west part of Polish Karkonosze Mountains has been characterized. A history of researchern, as well as the results of authors’own examination, consisting mainly of the morphology analysis of the basaltic body and structural analysis results, have been presented. Having thoroughly characterized the complex structure of this sub-volcanic intrusion, the authors rejected the opinion persisting in literature, that two thin veins exist there.
The temperature of standing water is one of the most frequently measured abiotic parameters of lakes. While some of the Tatra lakes have been investigated in modern times, those in the Karkonosze Mountains have never been an object of planned, systematic thermal studies. Our article presents the results of a unique methodology of research on the thermal characteristics of waters of Wielki Staw and Morskie Oko. They yielded full information about the vertical distribution of water temperatures in both lakes in an exceptionally warm month - July 2006. By employing gradient thermal probes, it was possible not only to give a general description of the thermal conditions of the lakes and the current development of stratification, but also to grasp the pattern of momentary fluctuations in the water temperatures of both lakes. The research has proved that the thermal conditions of the two mountain lakes largely result from their individual morphometric diversity. Also, in terms of thermal characteristics, the lakes should not be treated on a par with those of the other geographical regions of Poland; in favourable circumstances, the temperatures of their surface waters can reach values rarely met even among lowland lakes.
Głównym celem niniejszego opracowania jest próba określenia kryteriów do stworzenia mapy krajobrazów dźwiękowych szlaku turystycznego na przykładzie szlaku niebieskiego w Karkonoszach, na odcinku Karpacz Biały Jar – Mały Staw – schronisko „Strzecha Akademicka” – Przełęcz pod Śnieżką – Droga Jubileuszowa. Kolejnymi zamierzeniami są: sklasyfikowanie zjawisk akustycznych według źródła ich pochodzenia oraz opis metody wykonania mapy dźwiękowej a także jej prezentacja.

The hiker following a tourist trail, receive surrounding him geographic environment through many senses. The perception of the environment research confirms that 87 % of our perception of the landscape is visual and 7 % is hearing. But the research on sound perception (soundscape) are poorly developed in polish geographic literature comparing to visual perception (landscape like physiognomy). Definition of soundscape introduced musicologist R.M. Schafer and its component of multisensorical landscape in reason to T. Bartkowski (1985). The soundscape is the subject of research in acoustic ecology which target is to protect silence against noise, to save natural sounds, search and contemplation of soundscapes. The soundscape can be presented on map like an effect of soundwalks (sound physiognomy) and as a supplement of sight. There are difficulties in accurate locating soundscape in space and map because of its big dynamics. That is why more important is to locate it in trail space than to define its borders. The soundscape map of trail will be effect of field observations. It should lead to outline typology and evaluation of soundscape. The basis of typology and evaluation should be to determine positive, negative, natural and anthropogenic sound events. The soundscape map will be base to determinate silence zone protection and unique natural sound event. Evaluation of soundscape must be component of the mulitisencorical landscape of trail.
In 1989 a m easuring overflow was built on a small water-course in the East Karkonosze Mountains in order to determine the dynamics of flow and bedload transport. The data collected in a 0.99 square kilometers basin reveal that the bedload m ass in valley river-beds is considerably bigger than in slope streams. It has been shown that the bedload transport process is different for the naturally afforested areas and in conditions of anthropopressure, in which the material transport increases drastically. The observed minor retention of bedload in river-beds and its fast renewal indicate that big precipitation and ablation stimulate quick bedload transport and renewal of its resources during the settling of the flood wave. Since the measurements commenced, an upward trend of bedload transport has been noticed, which results from the increasing influx of water into the basin as well as from the progressing anthropogenisation of the whole area. It has been noted that the rnain bedload mass is carried out of the basin during intensive summer rainfall, w hen floods are the biggest although they take place rarely: once in a few years. In all, the flowing water has carried from the basin area over 50 tons of river bedload, there of 8.8 tons by the slope stream system.
