With the development of construction on socialist modernization and proving of urbanization, the interaction between urban and rural has been increasing seriously. Therefore, urban-rural-integration area becomes the preferred area of city growth, and inconsistency inspired and exposed of development between it and construction land is more fiercely. This paper chooses urban-rural-integration area of Liuzhou as research object, combining DSR model, fully discusses state, driving force and regulatory control of construction land expanding, and analyzes its mechanism of expansion in construction land. The main content and conclusions of this paper comprise some aspects blow:(1) From studying literatures about land use characters of urban- rural- integration area at home and abroad, the paper concludes emphasis and advances researched by scholars on different subjects background about land use problems of urban-rural-integration area.(2) Introducing the development source and characteristic of DSR model, the paper links the model and expansion mechanism, which contains state of expansion, driving force of. expansion, and regulatory control of expansion, and constructs the DSR expansion mechanism model of urban-rural-integration area's construction land.(3) This paper defines extension of urban-rural-integration area of Liuzhou, analyses characters of time and space sides of construction land, and finds that the increasing of construction land is impacted by macroeconomic control of National land significantly; The special distributing shows itself axial and annular.(4) Impacting indexes of construction land in urban-rural-integration area can be divided into politics and planning, population and urbanization level, people's living standers etc. five aspects. Conclusions indicate that: politic and planning impact expansion mainly from farmland preservation and construction land total supply; population and urbanization is the core; economic developing is the root to construction land.(5) Lastly, from strength urban-rural unified management, protecting ecology isolated area and set sustainable development idea etc., politic suggestions on expansion control of construction land in urban-rural-integration area are out forward.
