摘要：

农业适度规模经营是中国农业可持续发展的迫切需求。为合理确定农户适度经营规模，从社会、经济和环境3个方面选取9项指标，构建农业土地利用综合效应指标体系，并应用层次分析法（AHP）和熵权法确定指标权重，尝试对洞庭湖区不同农户农业用地经营规模的社会-经济-环境综合效应进行分析和比较，并以桃江县为例进行实证研究。结果表明，仅从社会、经济和环境的单一效应分析，农户经营规模在>6.67~20.00 hm²时社会效应最佳，>0.67~2.00 hm²时经济效应最大，>20.00 hm²时环境效应最优；从社会-经济-环境综合效应分析，在政府视角下，经营规模在>6.67~20.00 hm²之间的农户综合效应最高；而在农户和学者视角下，>3.33~6.67 hm²时农户综合效应最佳；结合协调度分析，桃江县农户适度经营规模应在>3.33~6.67 hm²之间，其不仅具有较高的综合效应，而且社会-经济-环境效应的协调度较好。开展不同农户经营规模的农业土地利用效应评价研究，有助于探寻社会-经济-环境效应均适宜的农户经营规模，以实现农业可持续发展。

Abstract:

It is an urgent need for sustainable development of agriculture in China to have proper farming scales. To rationally define proper scales for household farms, an index system for comprehensive effect of agricultural land use was built up, consisting of 9 indices concerning society, economy and environment with weights of the indices determined using the AHP and entropy method, in an attempt to analyze and compare comprehensive societal-economic-environmental effect of agricultural land use under different scales of household farms in the Tongting Lake Region. Taojiang County, located in the Dongting Lake Region, was selected for the case study. Results show (1) individuals effect analysis indicates that household farms, >6.67-20.00 hm² in scale, were the highest in societal effect, those, >0.67-2.00 hm² in scale, were in economic effect, and those, >20.00 hm² in scale, were in environmental effect; however, comprehensive effect analysis shows that differently from the angle of the government, household farms, >6.67-20.00 hm² in scale, were the highest in comprehensive effect, while from the angle of the farm households and scholars, household farms, >3.33-6.67 hm² in scale, were the highest in comprehensive effect; and (2) when coordination degree analysis was performed in addition, >3.33-6.67 hm² was held to be the optimal scale for household farms in Taojiang County. Household farms of such a scale were quite high not only in comprehensive societal-economic-environmental effect, but also in coordination degree of the three aspects. All the findings may help find a proper household farm scale suitable to achieving the optimal comprehensive societal-economic-environmental effects so as to realize sustainable development of agriculture.

Key words: farmer households, farming scale, AHP, entropy method, comprehensive effects
