摘　　要：为探索长江中下游粮食主产区农业面源污染对粮食经济生态压力的内在机理,文章基于"压力-状态"模型进行粮食经济生态压力测度,选取了单位耕地面积农药施用量、单位耕地面积化肥施用量等8个变量,通过评价值转化、综合评价值计量、协调度测算等方法剖析研究区域的粮食经济生态压力水平。结果显示:江汉平原位为流域粮食经济生态综合压力之首,江汉平原的天门和仙桃的粮食经济生态压力亦在其他区域之上,流域内多地呈现出综合评价得分与协调度评价值呈负相关的态势,表明地区隐藏的生态危机广泛存在。研究结论:(1)经济发展与生态农业发展的不同步导致粮食经济生态压力高企。(2)农业面源污染的根源在于农业生产思想对农户行为的驱使。(3)规范新型农业经营主体经营行为同样是治理农业面源污染的重要环节。The study of agricultural non-point source pollution on ecological pressure of food economy in the Lower Yangtze region aims to explore the present situation. And through the analysis, it explores the internal mechanism among the influencing factors on ecological pressure of food economy. Through the analysis of Pressure-State, it measures the values of ecological pressure of food economy. The variable system consists of 8 variables, such as consumption of chemical pesticides per unit area, consumption of fertiliser per unit area and so on. Then, the progress of measurement consists of some parts, which are value transformation, calculating the comprehensive evaluation value and coordination degree. The results show that the comprehensive evaluation level of ecological pressure of food economy in Jianghan Plain is the highest among 5 areas. The pressure of cultivated land ecological pressure in Tianmen and Xiantao are also higher than others. Negative correlation has shown on comprehensive evaluation score and value of coordination evaluation. Therefore, ecological crisis has hidden in the area. With methods of analysis, the conclusion has three parts.(1) The economic development and ecological agriculture development in different path lead to high level of ecological pressure of food economy.(2) The root of agricultural non-point source pollution is agricultural production ideology, which can drive the production behaviors of farmers.(3) To perfect the production behavior of new type agricultural operators is also the important part in the treatment for agricultural non-point source pollution.
