土地利用协调度压力-状态-响应评价模型

【目的】为科学、定量地评价土地利用协调度,为政府加大宏观调控力度和土地高效利用提供科学依据。【方法】从人地关系的角度入手,采用层次分析法和熵值法结合计算指标权重,建立一个评判指标体系———土地利用协调度的"压力-状态-响应"(Pressure-State-Response,PSR)评价模型,再根据柳州市2008～2012年土地利用数据评价柳州市土地利用协调度。【结果】模型的评价结果与柳州市的发展趋势相一致。【结论】PSR模型可科学、定量地评价研究区域的土地利用协调度。

Design of PSR Evaluation Model Based on the Coordination Degree of Land Use

[Objective]The purpose of this article is to scientifically, quantitatively evaluate the land use coordination degree, strengthen the macro-control of land utilization and provide scientific basis for efficient land utilization.[Method]Relations from a human perspective combined with the calcu-lation of the index weight using AHP and entropy method, a scientific evaluation index system：land use coordination degree of pressure-state-response （ Pressure-State-Response,PSR） evaluation model is established. According to the land use in Liuzhou from 2008 to 2012 years, coordination degree of land use for Liuzhou city is evaluated.[Result]The results from evaluation model is consistent with the development trend of Liuzhou.[Conclution]PSR model applied to the land use is a feasible sci-entific, quantitative method for the evaluation of regional land use coordination degree.
