Title: Peri-urban ecosystem research: Chinese perspectives 


Globally, rapid urbanization, along with economic development, is dramatically changing the balance of biogeochemical cycles and impacting ecosystem services. A key feature of the urban ecosystems is that nutrient stocks, carbon (C), nitrogen (N) and phosphorus (P), are being enriched, through human bio-concentration. Furthermore, these nutrients are not being returned to support primary production in rural/peri-urban environments. In contrast to natural and rural agricultural landscapes, urban environmental systems are also highly engineered and biogeochemical cycling of nutrients within them is spatially segregated. To accommodate these distinctions we propose the concept of the Peri-URban ecosystem (PURE). Through the merging of conceptual approaches that relate to Critical Zone science and the dynamics of successional climax PURE serves the symbiotic interface between rural/natural and urban ecosystems and allow re-coupling of resource flows. Thus, PURE provides a framework for tackling one of the most pressing societal challenges posed by urbanization, namely, securing food supply in rapidly urbanizing centers while progressing

global sustainability goals for both urban and rural environments.
