Spatial organization of facilities depend on the analyzing of the
distribution of the networks of establishments and service centers in cities
with focus on the study of complementarity and comparability of the
place, place settlement (place distr
ibution and density), service areas,
wider access of shopping service, in addition to a good coordination
(administrative, technical and consumptive) forming the place service
construction. This should all lead in the end to the best geographic
distribution of the networks of facilities and service centers within a
comprehensive and complete system in cities at present and in the future.
Good geographical distribution of service location must reduce the
consumers' time and create the largest possible social and economic set of
activities. There must be justice in distribution, and equal access to the
services, in addition to satisfactory quality for the population in quantity
and variety, in a way that corresponds with the natural, social,
demographic, economic and constructive conditions of the place (like city
size, shape, functions, location, the population and their qualifications,
the opening times during which the city can provide the service to the residents, the percentage of service consumers and their class, the nature
of the organizing plan of the city and the use of the land there, the road
net, and means of transport and others.)
The establishments, service centers, facilities and the services are
distributed to suit in quantity and variety with the residential districts and
territories. The central part of the city contains most service activities,
because it forms the easiest way of getting transport, and this identifies
the great importance in place in organizing services in the city. The
smallest the city is, the better the access to services.
It is necessary here to distribute the service establishments among the
city quarters, regions, places of work, social and scientific centers, and
locations of access to means of transport. It must emerge from the
consumers' preferences and their interests, the state capacities, and the
constant need to develope the planning of residential services in the city
The landslides and avalanches formations represent serious
danger on the constructions. They interfere with Tectonic conditions
to constitute a constructive system in some cases. Therefore appear
the importance of this study, which focused on the
tectonic role of
these phenomenon in Al Bassit area, NW. Syria, where different
deposits, mostly volcano- sedimentary of Ophiolitic complex. The
field executed studies and their analysis have permit to determine
the lithological and tectonic factors which have affecting the region.
Also the study of slope slip and characterizations have been studied
and an important comparative tables are proposed to study globally
and locally these landslides, and serve as a model for future studies
to prevent the risks of these slips.
