中国鱼-稻模式生态渔业:发展历程·生产效益·服务功能

Chinese Ecological Fishery of Fish Farming in Paddy: Development History, Productive Benefit,Function of Service

近30余年,中国鱼-稻模式生态渔业作为产业从起步性发展到生产性发展、再从拓展性发展到综合性发展,显现出它的勃勃生机,取得显著的经济、社会和生态效益。然而,鱼-稻模式生态渔业系统的产品和生态服务价值并没有得到应有的重视。其实,鱼-稻模式生态渔业系统不仅提供重要的初级产品——稻谷、水产品等食物以及作为副产品的秸秆,还提供区域空气质量维持、区域气候调节、疾病控制、环境净化和观光休闲等服务和功能。所以,关注鱼—稻模式生态渔业的发展,客观评价和科学认识其产品和生态服务价值,是促进鱼—稻模式生态渔业可持续发展的重要前提。
