基于AHP方法的土地利用现状评价与分析

An Evaluation and Analysis of Land Use Based on AHP

以湖北省咸宁市为例,应用AHP方法进行土地利用现状评价。根据咸宁市的特点,建立土地利用现状评价指标体系,利用AHP方法确定各指标的权重,采用综合评价方法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总体水平等方面对咸宁市的土地利用现状进行评价。结果表明:咸宁市土地开发利用程度低于湖北省平均水平,土地开发利用的潜力较大;土地集约利用水平远低于全省平均水平,土地利用的集约程度亟待提高;土地利用综合效益略高于全省平均水平,土地综合利用效益较高;土地利用总体水平略低于全省的平均水平,还有较大的提升空间。

With Xianning City in Hubei Province as an example, this paper applies the method of AHP to evaluate the present condition of land use. According to the characteristics of the city, the paper establishes indices system for present land use evalua- tion, calculates weights of indices using the method of AHP, and appraises the present land use of the city in terms of land devel- opment and use, intensive land use, comprehensive benefits and overall level of land use. The results show that （ 1 ） the level of land development and use is lower than the average level of Hubei Province, and there is a potential of land development and use in the city ; （2） the level of intensive land use is lower than the average level of the province as a whole, and land use intensity should be improved; （3） comprehensive benefit of land use is a little higher than the average level of the province ;and （4） the overall land use level is a little lower than the average level of the province, which should be improved.
