are the complete systems of general concepts, relief claasications,
legends and use of cartography means, providing
the compilation of comparable maps of every scales and
territories. Such system was elaborated at Moscow University;
similar principles are widely used in Russia and other
countries.
The basic maps must give the objective and expressive
image of real relief stressing on reliable features of genetic
importance e.g. relief patterns of tectonic origine. Such
mapping though well elaborated requires now the further
development as participating in the progress of Earth
sciences. The megarelief and global mapping become especially
important. It corresponds to the destinity of lag as
all-World organization. lag is in need of such maps as
means for common vision of the Earth, comparison of its
parts, discussions and further works of the kind. The existing
maps show that they are necessary for investigation of
principal problems of geomorphotectonics; general evolution
of the Earth, deep mechanisms, solution of contradictions
between fixism and neomobilism etc.
As immediate measure there can be recommended the publication
in English of the Geomorphlogical Map of the
World 1:15 mln, eds. N. Bashenina & O. Leont'ev, published
in Russian at 1988. This Map as also similar ones is
well proved. It is not obsolete and can be fast re-published
with non-essential improvementa. The preparation can be
realized by Russian co-authors of the Map. The proper recommendations
and decisions of the Conference on this
work and printing of the Map are necessary. The compilation
of the geomorphological map of Asia (and further Eurasia?)
on initiative by prof. Chen Zhiming also must be
supported.

Route evaluation and selection for a 500 kilovolt
electric transmission line in Malaysia:
an environmental assessment
Department of Geography, University of Malaya,
50603 Kuala Lumpur, Malaysia
This paper describes a methodology for selecting a 500 kilovolt
(kV) transmission corridor using various environmental
and other criteria and applies the approach to a
transmission line siting problem in Peninsular Malaysia.
Two main corridor alignments and varoius sub-alignments
are investigated, each investigation covers diverse physical
and human environments. Corridor selection is based on a
factor scoring technique of environmental characteristic
measured along the alignments. The major factors considerd
are the cost of construction, opration, and maintenance
of the transmission cables and towers (pylons), land
costs and the impact on the human and physical environment.
Routes were ranked on their overall total weighted
296
factor scorces (Otwfs), with the lowest scores being the
most attractive.
One alignment located towards the coast would involve
very high development and environmental costs (highest
Otwfs value), because it cuts across extensive area of
swamps and peatland, rich in flora and fauna. An alternative
route, located towards the inland of the Peninsular, was
best in terms of low development and environmental costs
(lowest Otwfs value). However, it had high human costs
(incurred in relocating settlements, industries, schools
etc.). This assessment is designed to help decision makers
evaluate the nature of the tradeoffs for this tyoe of important
infrastructure projet.

The estimation of relief stability of urban territories

The estimation of relief stability of urban territories upon
action of technogenic loads is actual problem in the modern
applied geomorphology. Ecologic situation of urban
territories is forming as an integral action of synenergetic
natural and technogenic factors whose relations may determine
the range of time-spatial environment changings. As
one of the basic elements of landscape the relief is exposed
to the most significant transformation which in some cases
cause to lower stability of geomorphology systems especially
as a result of disbalanced technogeneous action on geomorphological
systems when the negative endogenic and
exogenetic processes become active and consequently zones
of geoecologic risque arise.
Zoning of urban territories on geoecologic risque rate may
be effectively performed by estimation of relief stability
upon technogenic loads. Under the engineering geomorphology
researching we consider the concept of relief
stability as the ability of all landforms to withstand the technogenic
load keeping its structure and functional character
invariant in some limits. With the aim of thorough
analysis we propose to consider the urban territory as a nature-technogenic
geomorfology system with account of endogenic,
exogenic and technogenic factors of relief making
processes. The author proposes an practical method of relief
stability estimation of urban territories of Kyiv the capital
of Ukraine. When studying the urban natural-technogenical
geomorphologic systems we analyse the functional
connection and interaction of natural and technogenic relief
elements on the basis of historic-geomorphogical,
morpholitological and geomorphodynamic approach.
The historic-geomorphologic analysis of urban territory is
based upon complex usage of historic and archeologic data
to determinate the main stages of urbanization as a time
