鄱阳湖生态经济区农业循环经济发展综合评价

发展农业循环经济是鄱阳湖生态经济区建设的关键，农业循环经济发展的目标是实现农业生产经济效率和生态环境效率的双赢。应用DEA方法以评价循环农业发展的经济效率，采用农业生产的生态足迹以反映农业循环经济发展的生态效率。在此基础上，为同时体现农业循环经济发展的经济效率和生态效率，构造了区域农业循环经济发展评价的综合指数，并对鄱阳湖生态经济区的农业循环经济发展进行评价分析。结果表明，大部分地区存在农药化肥投入冗余、粮食单产不足以及农业生产的耕地足迹和牧草地足迹所占比重偏大等问题，为此必须在推广猪－沼－粮的同时，调整农业产业结构，着力发展猪（牛）－沼－果（渔）等循环农业模式，进而提高鄱阳湖生态经济区农业生产的投入产出效率，降低农业生产的生态占用

COMPREHENSIVE EVALUATION ON THE DEVELOPMENT OF AGRICULTURAL CIRCULAR ECONOMY IN POYANG LAKE ECO-ECONOMIC ZONE

Development of agricultural circular economy is vital for construction of Poyang Lake Eco-economic Zone.It aims at achieving the double-win of economic efficiency and ecological efficiency of agricultural production.This article applied Data Envelopment Analysis(DEA) to evaluate the economic efficiency of agricultural circular economy,and adoptd ecological footprint of agricultural production to reflect the ecological efficiency of agricultural circular economy.For the purpose of evaluating simultaneously the economic efficiency and ecological efficiency of agricultural circular economy,a comprehensive index was introduced for evaluation of regional development of agricultural circular economy,and applied to Poyang Lake Eco-economic Zone.The result showed that the most areas faced the problems of pesticide and fertilizer input redundancy,low grain yield per hectare and high proportion of arable land and grassland footprints.It indicates that,in addition to spread the circular agricultural pattern of ’Pig-raising,Methane-generating and Grain-growing’,the areas must adjust agricultural structure and develop other circular agricultural patterns such as ’Pig/cattle-raising,Methane-generating and Fruit/fishing-growing’.Thus in Poyang Lake Eco-economic Zone,the input-output efficiency of agricultural production will be improved and the ecological footprint of agricultural production will be lowered.
