从人口、社会、经济、环境以及资源等5个子系统选取21指标构建农业可持续发展指标体系,用熵值法、协调度方法分析我国粮食主产区2004—2015年农业可持续发展动态差异和协调度。结果表明：从时间维度看,2004—2015年我国粮食主产区农业可持续发展综合指数均值呈先波动下降再上升再下降的趋势,波动幅度较大,其综合指数均值为0.3983;从空间维度看,粮食主产区所在省域农业可持续发展综合指数均值由东部向西部递减,其中,华东地区综合指数均值最高,其次是东北地区,内蒙古及华中地区居中,西部的四川、华东的安徽、东北的吉林等三省综合指数均值最低;从农业各子系统可持续能力之间协调度看,2004—2015年粮食主产区各子系统可持续能力之间的协调度有所趋好,但整体发展水平有待进一步提高。

From the 5 subsystems of population, society, economy, environment and resources, 21 indexes were selected to construct the index system of agricultural sustainable development, and the dynamic differences and coordination degree of agricultural sustainable development in 2004-2015 years of grain-production areas in China were analyzed by entropy method and coordination degree method. The results showed that: from the time dimension, 2004-2015 average comprehensive index of sustainable agricultural development in the areas are swings down first, then the trend of rising and falling, volatility is high, the composite index average of 0.3983; From the spatial dimension, the mean value of the agricultural sustainable development index of the provincial agricultural sustainable development in the main grain producing area is decreasing from the east to the west, among which the average value of the comprehensive index in East China is the highest, followed by the northeast, the middle of Inner Mongolia and central China, the Sichuan in the west, the Anhui in East China, and the Jilin in the northeast of the northeast is the lowest; According to the coordination degree of the sustainable ability of the agricultural subsystems, the coordination degree of the sustainable ability between the subsystems of the major grain-producing areas in the 2004-2015 years has been better, but the overall level of development needs to be further improved.
