The patterns of urbanization control ecosystem dynamics. This paper summarized the mechanism model of impact of urbanization on ecosystem functions, and experimentally studied the quantitative relationships between urbanization level and ecosystem functions in southern urban-suburb-rural area of Xi’an City, a typical research region. Following conclusions were drawn: (1)the population convergence, industrialization and land-use change lead to modification of natural landscape, biophysical processes and habitat, and biogeochemical cycles in the process of urbanization, which have an important impact on the ecosystem functions; (2)in general, urbanization will inevitably lead to the decrease in capacity of ecosystem services, but there were significant different influences of urbanization mainly caused by population grwoth, economic development and landscape transformation separately on ecosystem functions. The landscape transformation of urbanization has more remarkable negative impacts on different ecosystem functions. Empirical analysis shows that: there were more significant negative impacts of urbanization on climate regulation, soil conservation, waste disposal and food production in the northwest valley plains, while the impacts of urbanization on biodiversity maintenance, production of raw materials and cultural entertainment functions are not significant.
