从耕地集约利用内涵界定出发,以甘肃省耕地自然条件和现状数据为依据,从耕地投入强度、利用程度、产出程度和可持续利用状况等4个方面构建耕地集约利用评价指标体系,采用基于灰色关联度的多因素综合评价和聚类分析等方法对甘肃省各地区耕地集约利用现状水平进行评价,并对引起不同耕地集约利用水平的原因进行探究.揭示了甘肃省各地区耕地集约利用水平的规律和影响甘肃省耕地集约利用水平的各指标之间以及它们与耕地集约利用水平之间的关系.

From defining the connotation of cultivated land intensive use, based on data of natural conditions and status of cultivated land in Gansu Province, the evaluation index system was constructed from four aspects, including input intensity, utilization degree, use efficiency and sustainable utilization. The level of cultivated land intensive use in various areas of Gansu Province was evaluated by using the methods of multifactorial comprehensive evaluation based on grey relationship and the clustering analysis, the reasons that result in different levels of the cultivated land intensive use were explored. The research revealed laws of the cultivated land intensive use level in various areas of Gansu, and the relationship among influencing indicators and intensive use level.
