摘要：This paper takes Jinan as the research area, constructs the evaluation index system of intensive utilization of cultivated land based on domestic and foreign research and the present situation of cultivated land utilization in Jinan, combines the analytic hierarchy process (AHP) and entropy method to determine the weight of each index and calculates the degree of intensive use of cultivated land. On this basis, the time dynamic change of intensive use of cultivated land in Jinan from 2005 to 2016 and the spatial difference of intensive use of cultivated land in various regions in 2016 were analyzed and the cultivated land intensive utilization degree in 2016 was classified by using ArcGIS10. 2. The results show that: from the time scale, the intensive utilization of cultivated land in Jinan from 2005 to 2016 shows an overall upward trend, with the smallest in 2005 and the highest in 2014. From the spatial scale, Jiyang county and Shanghe county are the largest in intensive utilization of cultivated land in Jinan in 2016, while the urban area and Tianqiao district are the smallest. In general, intensive utilization in plain area is greater than that in low mountainous and hilly area, and the township area is larger than the urban construction area, which accords with the "concentric circle structure" in agricultural location theory.
