AHP Evaluation Study of the Land Use Intensity on Regulatory Plan Management Unit Level of the Small and Medium-Sized City in Guanzhong Area

ABSTRACT

The paper, by taking Pucheng, a typical small and medium-sized city in Guanzhong area, as an example, conducts a study on the scientific determination of land use intensity zoning at the regulatory management unit level by reference to the analytic hierarchy process (AHP) model. Meanwhile, this paper constructs evaluation methods and systems of land use intensity zoning at such level. This evaluation system can be summarized as "four levels and two steps". "Four levels" refer to the total target level (T), total factor level (A), sub factors level (B) and index level (C) respectively. Two steps are first classifying the basic factors through weighing the most underlying factors (namely, the index level) and second calculating the weight of each unit in terms of each factor level to get the weight of each unit under the dominant influence factors and minor influence factors, and establish basic intensity and modifying zones so as to finally determine the ultimate reasonable zoning of land use.
