In this study the urban system of the governorate of Lattakia has been examined
through the applicability of measurements of the equality of spatial distribution patterns of
cities (Demangeon Index and Lorenz curve), and those of Primacy and cities
size
distribution patterns (the Law of Primate city of Mark Jefferson, 1939, the Index of
Primacy of Stewart, and the hierarchical order of city through the Rank-size Rule - George,
K. Zipf, 1949). It has been identified on the size of the imbalance equilibrium in the system
urban cities through Urban Isostastic Index. The results of the study showed a clustered
patterns of the spatial distribution of urban centers according to the value of Demangeon
Index (0.42) and unequal distribution of urban population to the cities (75% of urban
population are distributed on 15% of cities). It showed also a great domination of the
primate city of Latakia on the urban system where the population volume was (6.1) time
bigger than the volume of the next cities according to Primacy Index; a great decrease of
the real value of the next cities comparing with the theoretical value of Law of Primate
City (16.4%) against (67%), and disability to applying the Rank-size Rule.
