英文摘要：

Urban planning and urban policies attended to restrain the collective land exploitation for the purpose of urban extension. Lots of rural lands were changed into non-rural land use illegally since the late 1990s. Collective lands had negative effects for urban development, such as urban-rural conflict, low land use efficiency, rural-urban transition etc. Facing with the serious situation, it＇s necessary for urban government to learn how to construct the city based on collective land, which was different from the past experiences.
