ABSTRACT: The distribution of population size of cities follow a high degree of empirical regularity termed Zipf’s law, which establishes that the population of a city is inversely proportional to its rank within in a system of size-ranked cities. Generally, the largest city will be twice as large as the next largest city, and so on, allowing practical predictions regarding city size, and generalized knowledge about urban systems. In addition, Zipf’s law has been observed in other urban-related phenomena, such as network theory, income distribution, and firm size among others. Research has demonstrated that landscape ecology metrics in other contexts follow power laws similar to those observed in urban phenomena. However, the statistical relationship between landscape ecology metrics applied explicitly to urban landscapes within a population rank system is yet to be fully explored. The objective of this study is to examine the distribution of urban structure characteristics measured through landscape metrics within a population size-rank system of cities. The analysis is carried by plotting metric values against their population rank ordering for more than 2000 Mexican cities. Mexico was selected as the study area given the highly hierarchical structure of cities across the country, as well as a shared pattern of growth that make it a true system of cities. Preliminary results suggest that some metrics such as SHAPE, GYRATE, NP, and TE among other show strong statistical relationships in a manner concordant with Zipf’s law.
