In recent years, with the intensifying contradictions of our people and the deepening of the agricultural structure adjustment , the protectorate agriculture has become to improve agricultural efficiency , an important way to promote the efficient use of resources and the development direction . Protection of land- use characteristics of the research is the prerequisite and basis for the smooth and healthy development of agriculture protectorate . From the theoretical analysis on the basis of the analysis of the concept of protected areas and their production characteristics , characteristics of the land use of the protected area : the multidimensional characteristic protected area land use , land productivity protectorate unnatural formation process intensive efficiency characteristics and protection of land- value - added channels and substance . The introduction of the concept of land equivalent ratio , to open contrast from three aspects of output, output value , net income of expression protected area land utilization to improve and protect the land- value-added indicators : protected areas yield equivalence ratio protectorate output value equivalence ratio The protectorate revenue equivalence ratio . Quzhou County , Hebei Province , vegetables protected as the research object , using the \draw protected Vegetable relative to open field production , the output value , net income equivalent ratio , and cluster analysis . On this basis , the study established a the land appreciation protectorate protectorate net income when compared to the relationship between open field premium through in open premium assessment , calculation of the protection of land appreciation and protection of land price . The correct valuation protection artificial value-added protection development predict important theoretical significance and application value .
