浙江省农地规模化的空间潜力与减氮增效研究
Potential of large-scale farming and its effect on nitrogen reduction and yield benefit in Zhejiang
摘要
Abstract
Chinese agriculture is dominated by smallholder farms.To solve the problems of low agricultural profitability,low utilization efficiency of agricultural resources,and serious non-point source pollution in Zhejiang Province,this study analyzed the distribution of Zhejiang farmland,quantified the potential and spatial optimization path of large-scale farming,and combined farmland nitrogen balance and cost-benefit analysis to assess the impact of large-scale farming on agricultural production and environmental effects.The results showed that the average size of cropland in Zhejiang is 0.4 hm2,and 70%of cropland is<0.6 hm2.Through land consolidation,73%of the arable land reaches a contiguous area>16 hm2.Large-scale farming can reduce the nitrogen input by 53%and increase the nitrogen utilization efficiency from 38%to 56%.Agricultural labor demand can be reduced from 4 to 1 person per hectare,agricultural costs can be reduced by 77%,and the average agricultural labor productivity can be increased by approximately 9 457 yuan.Zhejiang has ideal resource conditions for the promotion of large-scale farming,and its implementation in the entire province can help improve the quality and efficiency of agricultural production and protect environmental resources.The government should strengthen policy guidance,increase financial support,and promote agricultural transformation,so that large-scale farming can improve the potential for sustainable agricultural development.关键词
