AHP Evaluation Study of the Land Use Intensity on Regulatory PlanManagement Unit Level of the Small and Medium-Sized City inGuanzhong Area

摘要

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