The systematic and multiyear studies of Wolin cliff coast
give good opportunity to establish regularities of presentday
morphodynamics and its trends within this morphogenetic
environment.

Termination of Pleistocene glaciation and Holocene
environmental changes in the High Tatra Mountains,
Poland

Late Pleistocene and Holocene changes in both glacial and
other geomorphic processes have been studied in the High
Tatra Mountains. These efforts are based on the interpretation
of glacial forms and deposits, peat bog palynological
studies, and lacustrine sediments analysis. Distinct links
between alpine glacial forms, geomorphic processes and lacustrine
sedimentation exist. The main argument for defining
the time of the full retreat of Late- Vistulian (Wiirm)
glaciers are lacustrine sediments of alpine lakes of the High
T atra. Successive stages of valley glaciers retreat from terminal
position are topographically marked by a system of
eight recessional moraines. Lacustrine sediment record reflects
climatic and floristic changes. Three stages of the development
of the Tatra environment have been distinguished:
1. the stage of recession of valley glacier tongues - period
probably lasted ca. 4 ka, i.e. to the alpine Gschnitz stade,
2. the stage of Gschnitz-Daun-Egesen recession has been
reconstructed based on the sediments of dead-ice depressions
and lacustrine deposits in the valleys free from the ice,
3. the early Holocene stage of warming and glacier decay
in majority of the Tatra valleys lasted until alpine oscillation-Venediger.
Small glaciers were preserved only in the
uppermost parts of the mountains (above 2000 m a.s.l.).
Relict rock glaciers are common features at altitudes ranging
from 1450 m to 1950 mm. Boundary conditions for
their development (existence of alpine discontinuous permafrost)
existed in this altitudinal belt during the Younger
Dryas and probably were active until the Venediger phase.
Subbotom profiles of the Holocene lake basins provide additional
information regarding the relationship between
non-glacial changes in the environment which was under
the influence of periglacial climate. The data collected in
several lakes indicate that lake sedmientation rates differ
significantly from
- ca. 0.1 mm/yr to 1.29 rnm/yr, Generally, the Holocene
cores showed that calm, slow sedimentation of organic silts
predominated during the first phase of the Holocene, i.e.
in the Preboreal and Boreal. Massive mineral sediments
were formed in the period preceding the radiocarbon date
- ca. 8300 BP. The high sedimentation rate is correlated
with global event-the Joux phase (8700-8300 BP). During
the Atlantic period, lasting until
- ca. 5000 BP, sedimentation was calm. The Subboreal
period manifested in a more vigorous processes of the Tatra
environment (mineral gravel-sandy inserts in the cores)
predominated. The last, large scale reactivation of slope
geomorphic processes occurred during the Little Ice Age.

Environmental problems: ecological conditions
in coal mining areas in Primorsky Territory, Russia
Pacific Institut of Geography,
Radio st., 7, Vladivostok, 690041, Russia
Solving the problems of environmental nature, restoration
of disturbed territories and prediction of developing situations
is an actual need for the territories of economic development.
The coal mining poses environmental problems.
In this regard, zones of transition from the land towards
the sea in the Russian Far East are poorly known, the most
vulnerable and unstable to the anthropogenic loads.
The ecological conditions including qualitative and quantitative
changes inside environmental systems give rise to a
series of problems, which are conditionally divided as follows:
- geologic and geomorphological; land; soil; water; atmospheric;
biotic; landscape and recreational.
The analysis of environmental problems allows distinguishing
hydrodynamic processes of the anthropogenic nature
as well as territories concerning limitation on types of
man's economic activity. Anthropogenic processes of catastrophic
nature have evolved on the vulnerable, in view of
their natural features, minor Artem-Tavrichanskaya, Shkotovskaya,
Rettikhovskaya, Pavlovskaya depressions.
The environmental situation is conditionally taken as favorable,
normal, tense, critical and catastrophic. Recommendations
are given for solving the environmental problems
of coal fields.

Some particular features of the Albanian Karst
Geographic Studies Center, Rruga M. Toptani No. 11, Tirana, Albania
The Albanian karstic landscape, depending on a complex
of factors, is so particular as it orients the morphogenese.
We see this type of relief in all big natural regions, from
the sea level to the highest altitudes but the intensity, the
density of the forms and the sizes are different. The typical
karstic morphology is seen at the altitudes 600-2000 m
especially at the naked carbonatic rocks by the vegetation
and the soils, with low steepness of the slopes.
