Taking Huanggang city as a research area, using principal component analysis method and multi-objective decision-making method, the indicators of agricultural land input intensity, agricultural land use degree, agricultural land output effect and agricultural land sustainability were selected to construct agricultural land intensification in Huanggang city, and the intensive use of agricultural land was evaluation. On this basis, the intensive use of agricultural land in various counties （cities, districts） of Huanggang city in 2015 and the changes in the intensive use of agricultural land in Huanggang city from 2010 to 2015 was analyzed. The results showed that the comprehensive scores of intensive use of agricultural land in counties and districts of Huanggang city ranged from -0.78 to 1.22 in 2015, the overall intensive utilization level was in a medium-low state, and the intensive use of agricultural land in each county was different. Among them, the agricultural land in Huangzhou district and Luotian county was intensively utilized, the agricultural land in Yingshan county, Tuanfeng county and Huangmei county was generally intensively utilized, and the agricultural land in Wuxue city, Macheng city, Shachun county and Hong'an county was intensively utilized. The agricultural land in Qinshui county was extensively utilized. The comprehensive score of agricultural land intensive use in Huanggang city was between -0.40 and 1.15 from 2010 to 2015, and the intensive utilization degree showed an overall upward trend. The research results were in line with the actual use of agricultural land in the region, and corresponding suggestions based on the intensive use of cultivated land in Huanggang city were put forward, which had certain guiding significance for the efficient intensive and sustainable use of agricultural land in Huanggang city.
