摘要
作为一种典型的生态农业,稻田养鱼能在合理利用水土空间资源的同时实现种养耦合、绿色生产,拥有良好的经济、社会和生态效益。近几十年来,中国稻田养鱼生产经历了从"稻主鱼辅"阶段到"以鱼为主"阶段再到"稻鱼并重"阶段的3个发展历程,在田间工程、养殖品种、系统结构及生产技术等方面不断进步,使稻田养鱼的生产力和效益不断提升;同时,稻鱼共生系统作为一个复合农业生态系统和全球重要农业文化遗产,身兼产品提供、环境调节、文化服务等多种功能,并且随着稻田养鱼的不断进步,其功能进一步提升,使稻田养鱼生产在保障粮食安全、维护生态环境和促进文化传承等方面发挥出更大的作用。
As a traditional ecological agriculture,rice-fish farming could come true the goals of combining planting and raising,as well as green production at the same time reasonably to utilize the resources of water,soil and space. So,it had prominent benefits of economic,society and ecology. In recent decades,rice-fish farming had being made great progress and innovation in farmland works,breed,system structure and technology after undergone 3 development histories,which improved the productivity and benefits of rice-fish production. Meanwhile,as a compound agro-ecosystem and globally important agricultural heritage,rice-fish farming system has many functions,such as product provision,environmental adjustment and cultural service. With the advancement of rice-fish farming,its functions made great progress,which made it plays greater role in guaranteeing food security,maintaining ecological environment and promoting cultural heritage.
