Introduction
In the past decades, development policies in the country have caused negative
effects on regions. These policies have caused the mass evacuation of rural
settlement and the imbalance hierarchy of settlements. The reflect of these policies
are visible in the rapid and uneven growth of large cities and eliminate loops linking
between cities and rural settlements from the highest levels, to lower ones. Survey
the development on the rural community in past shows that the rural sectors faced
with the basic difficulty in the socio-economic and ecological aspects in national and
local levels, so that the continuity of this situation confronts them with problems
such as intensifying of regional in equalities, massive evacuation of human and
financial resources in villages, declining in per capital food production and emerging
food crisis, accumulation of population in urban communities, extension of
marginalization, unemployment and social damage. Present study with the purposes
of 1) prevent the rising trend of rural migration and make order of settlement pattern
in activity and population, 2) creation and establishment hierarchy in the settlement
of Damavand and 3) offer variety activities in rural settlements, consider these
questions:

development of settlements. However, the boom may be made by only one of the
basis strengths. For example in some parts, some rural such as Sarbandan and Jaban
in Abarshive district, Vadan in Jamabroud and Sadat Mahale in Abali district are
located adjacent to the communication paths. These villages, with use this features
and create service centers, have reached to a higher level of development.

positive features and capabilities. These settlements can be pointed by rural villages
in the south part of the Mehrabad and villages in the central part of the Abarshive
and Jamabroud district.
Conclusion
Proper utilization of the natural, social, economic and physical factors has caused
boom economic activity, attract population and prevent irregular migration. These
conditions will make hierarchical order of rural settlements based on their power and
capabilities. Lack of proper communication between rural and urban settlements in
Damavand district have caused poor performance and low-density of rural
settlements. If good communication of manufacturing and service facilities exist
between adjacent settlements, it will help to link rural and urban settlements together
to get the better performance. In addition to, the complementary relationship
between activities of agriculture, industry and services provide the grounds of
further development. Finally, according to descriptions provided in settlements
classified; in order to access available services and facilities of rural settlements in
the district and promote the level of that, 4 System villages are suggested in this
essay.
