基于AHP决策分析方法的天水市土地利用现状评价研究

Research and Evaluation on Land Utilization in the City of Tianshui based on the Analytic Hierarchy Process(AHP)

根据天水市土地利用特点,利用AHP决策分析方法建立土地利用现状评价指标体系,并确定各指标的权重。从土地开发利用程度、土地集约利用程度、土地利用综合效益以及土地利用的总体水平四个方面对天水市土地利用现状进行评价研究。研究表明:天水市土地开发利用程度高于甘肃省平均水平,开发潜力比较小;土地集约利用程度和土地利用综合效益均高于甘肃省平均水平;天水市土地利用总体水平高于甘肃省土地利用总体水平;但某些单项因子中,天水市土地利用存在不合理之处。

Land utilization and evaluation systems are shaped on the Analytic Hierarchy Process （AHP）, from which the evaluation norms will be defined. According to the present situation in Tianshui, the study focuses on land utiliza- tion in four respects： land developments, land collection, land synthetically utilization and the overall land utiliza- tion. It shows that the land utilization and development in Tianshui are higher than that of the average in Gansu while the latent capacity is limited. But land collection development and land synthetically utilization the both are higher than the average utilization and development in Gansu. The overall land utilization in Tianshui is higher than that in Gansu. But in some items are not rationally.
