The peri-urbanization area as a kind of rural-urban interface is changing rapidly ,physical, economlc and social terms. The land use pattern in such area is shifting away from the assumptions of mainstream paradigms to new conceptual landscapes, which leads to a series of problems on economic development and social stabilization. There are many researches on non-agricultural land-use in peri-urbanization area. In this paper both international and domestic research literature is reviewed by dividing six parts. The first part introduces the conception of peri-ur-banization area and its driver factors. Then in the second and the third part, the paper expatiates on the progress in the non-agricultural land-use in peri-urban area on land-use problems in the research area, while the fifth part reviews the integrating ways of non-agricultrual land-use. Finally, recommendations for further study are draw with specific reference to the current and future position of non-agricultural land-use study in peri-urban area. 展开更多
