自贡市稻田种植模式的经济效益分析

Analysis on the Economic Benefit of the Paddy Field Cropping Patterns in Zigong City

以自贡市稻田生态系统为研究对象,以2006—2011年农业生产相关数据为基础,对自贡市6种稻田种植模式:稻谷-冬闲、稻谷-小麦、稻谷-油菜、稻谷-西红柿、稻谷-黄瓜及稻谷-茄子的经济效益运用综合指数评分法进行系统的经济效益分析;对稻-鱼与单种稻谷模式运用投入产出分析法进行产投比分析.结果表明:1)稻-菜模式最优;2)稻谷-油菜与稻谷-小麦模式次之;3)稻-鱼模式产投比始终高于单种稻谷模式产投比.自贡市农户可以选择稻谷-茄子种植模式和稻-鱼模式二者结合的稻田种植模式,既可以增加其经济收入,又可以使稻田生态系统得到最优利用.

The paper regarded the paddy ecosystem of Zigong City of Sichuan Province as the research object and based on the related agricultural production data from 2006 to 2011,and then utilized the comprehensive index evaluation method to analyze the economic benefits of six cropping patterns of the rice paddy in Zigong City. The six cropping patterns were rice,rice and wheat,and winter fallow paddy and rape,rice-tomatoes,rice-cucumber and rice-eggplant. Then input-output analysis method was applied to compare and evaluate rice-fish and single rice. The results showed that 1） the rice-vegetable mode was the best; 2） the rice and grain pattern takes second place; 3） the rice-fish pattern output-input ratio was always higher than that of single rice mode. Therefore farmers in Zigong City could choose the two patterns： rice-eggplant and rice-fish,which not only increase the farmer＇s income but also improve the quality of cultivated land.
