Based on the Matter Element Extension Theory to Analysis Land Intensive Use during Urbanization in Guanzhong Region

Abstract

Accelerating urbanization is China's "The Fifth" period of economic and social development of an important part of the overall strategy.Urbanization construction process speeded up in Guan- zhong region in recent years.At the same time, many problems appeared, Guanzhong area of farmland for construction land increased year by year, while the Guanzhong area in northern and central located in the Loess Plateau and the Weihe Plain, is the most serious soil erosion in China, the ecological envi- ronment of the most vulnerable areas. Urban sprawl compressed natural environment space, and destr- oyed undermined the balance of the ecosystem.To under the premise of ensuring food security and ecological security, only to improve land use efficiency. It adopts the PSR framework model to build urbanization index system of intensive use of land.It used the matter-element extension theory to evaluate, designed to evaluate land use efficiency and benefit, To find out the problems existing in the current land use and seek the most effective use way of land and to achieve sustainable land use.
