摘要
统计广西稻田养鱼主要分布的桂北、桂西北、桂东南三个区域中的8个长期开展稻田养鱼的县和11个基本未开展稻田养鱼的县在1995—2004年问与农业资源利用效率有关的数据。对比分析表明：在同区域和同季稻条件下，稻田养鱼县的稻谷单产量普遍高于非稻田养鱼县，而单位化肥、农药的用量仅处于同区域的中低水平；非稻田养鱼县取得较高的稻谷单产水平是使用了大量化肥、农药的结果；部分非稻田养鱼县使用了比同区域的稻田养鱼县更多的化肥、农药，但稻谷单产仍低于稻田养鱼县。结论：广西稻田养鱼提高农业资源利用效率的作用显著。
A comparative method was used to analyze the data of national rural economic stat. Those data were from 10 years of practice（ 1995 -2004）of 8 counties with paddy-field-fish-culture and 11 counties without that, which located in the northern, northwest and southeast of Guangxi. The utilization ratio of agricultural resource had been compared among them in the same region in 1995 -2004. The study showed that： Under the same condition, from a long-term＇ s view： （ 1 ） the counties with paddy-field-fish-culture had an averagely higher unit yield and annual unit yield than those of the counties without paddy-field-fish-culture, but used less chemical fertilizer and less pesticide at the same time. （ 2 ） the counties without paddy-field-fish-culture couldn＇ t get higher or equal unit yield and annual unit yield compared with the counties that have culture fish in paddy fields do, unless they use a great deal of chemical fertilizer and pesticide. （ 3 ） Even some of counties using more chemical and pesticide fertilizer, still obtained an averagely lower annual unit yield than the counties with paddy-field-fish-culture. This research showed that the fish culture in paddy fields in Guangxi can obviously promote the utilization ratio of agricultural resource in paddy fields area.
