Abstract: Due to the unique geographical location， socio\|economic and population structure， environmental problems in urban\|rural fringe differed from those in the traditional countryside， where agriculture was the dominant industry， and the local residents were the majority of population. As industries were transferred to urban\|rural fringe from center city， the total population and the proportion of migrant workers increased greatly， and the industrial pollution load in these area also became much higher than in traditional countryside. Compared with traditional countryside， domestic wastewater and refuse in rural\|urban fringe were much higher， and accordingly increased the difficulty of environmental management. The present paper took Huaxin Town， a typical rural\|urban fringe in Shanghai as a case， to analyze the causes of environmental problems in this area from both industrial development and industry\|worker migration. Contiguous stretches were suggested to solve the environmental problems in the rural\|urban fringe.

Key words: rural\|urban fringe, urbanization, rural environment problem, new duality frame
