摘要
种粮收入是黄土沟壑区农民收入的重要来源之一,为揭示该区域主要粮食作物生产投入产出状况及其稳定性,选取黄土沟壑区长武县王东沟流域的30户农户为研究对象,对其种粮过程中小麦、玉米和大豆等主要粮食作物的投入与产出状况进行了为期10a的跟踪调查,并进行了成本效益分析。结果表明,大豆的生产稳定性最高,其土地产出率变异系数为14.2%;玉米次之,其土地产出率变异系数为17.2%;小麦的土地产出率年际变化较大,其生产稳定性最低。1999—2008年间,3种粮食作物的单位面积产值及生产成本均呈上升趋势。从而得出,在黄土沟壑区,种植玉米的经济利润最高,大豆次之,小麦最低。据此提出增加科技投入,加大政府对农业生产资料价格的监控力度及种粮补贴力度,以降低农民种粮成本增加种粮收入,促进粮食稳定生产,保证区域粮食安全。
Grain production is one of the most important income sources for rural households in the gully area of the Loess Plateau. In order to reveal the input-output conditions and stability of main grain crops production in the area,this paper used 10 years data surveyed from 30 rural households in Wangdonggou valley,Changwu County and mainly analyzed the input and output of wheat,maize,and soybean. Results from the cost-benefit analysis showed that soybean had the highest production stability and its variation modulus of output was 14.2%; maize had the second high production stability and its variation modulus of output was 17.2%; and wheat had the lowest production stability and its change in output was comparatively large. From 1999 to 2008,the output value and production cost of the three grain crops were all increased. Maize had the highest profit,followed by soybean and wheat. Finally,according to the results,some suggestions were given,such as increasing investment in science and technology,enhancing government control power in the prices of agricultural production materials,so as to reduce the cost of grain crops,increase farmers＇ income,promote stable grain production,and insure regional food security.
