The development of the concept of land use rate, and its advantage and disadvantage under the new situation were analyzed. The profound meaning of the land use rate was elaborated roundly in the extent, profundity and intensity of utility. Then the essence of the land use was distinguished, and the land use rate models were selected to assort and comprehensively evaluated the land use degree on county regional scale.

As a result, the land of high use-degree was focusing on the three areas: the first is Situan villages, which is the science and technology center of Quzhou County, the next is Hanlin highway belt, and the last is diffusion zone of Quzhou town, in which the agricultural cropping with high yield and high input efficiency.
