【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]:Moderate scale management of agriculture is the urgent need of sustainable development of agriculture in China. In order to reasonably determine the appropriate management scale of farmers, 9 indexes were selected from three aspects of society, economy and environment, and the index system of comprehensive effect of agricultural land use was constructed, and the index weight was determined by (AHP) and entropy weight method. This paper attempts to analyze and compare the social-economic-environmental comprehensive effects of agricultural land management scale of different farmers in Dongting Lake region, and takes Taojiang County as an example to carry out an empirical study. The results showed that from the single effect of society, economy and environment, the social effect was the best at 6.67 ~ 20.00 hm2, the biggest economic effect was at 0.67 ~ 2.00 hm2, and the environmental effect was the best at 20.00 hm2. From the point of view of social-economic-environmental comprehensive effect, the farmer's comprehensive effect is the highest in the range of 6.67- 20.00 hm2 from the perspective of the government, while the farmer's comprehensive effect is the best in the view of farmers and scholars when the scale of operation is between 6.67and 6.67 hm2. According to the analysis of coordination degree, the moderate management scale of farmers in Taojiang County should be between 3.33 and 6.67 hm2, which not only has a higher comprehensive effect, but also has a better coordination degree of socio-economic and environmental effects. The research on the evaluation of agricultural land use effect of different scale of farmers' management is helpful to explore the scale of farmers' management which is suitable for the social, economic and environmental effects, so as to realize the sustainable development of agriculture.
