生态工程是运用生态学的原理,在人工的辅助下,在物质和能量的参与下,以生物为基本组分的生产工艺系统。这种生产工艺系统的正确应用,将能有效地使生态效益和经济效益相统一,达到既有利于创造良好的生态环境,又有较高经济效益的目的。我国农业生产上正在应用的如:稻鱼共生系统,粮—猪—肥系统,肥—藻—鱼系统,粪—沼气—肥系统,桤柏混交,旱三熟分带轮作聚土免耕等等都是生产中发挥了很好经济效益的生态工程,已引起了生产者、科技工作者的普遍关注。
Ecological engineering is the production process system that uses the principle of ecology, with the aid of manpower and with the participation of material and energy, and takes the biological as the basic component. The correct application of this kind of production technology system will effectively unify the ecological and economic benefits and achieve the goal of creating a good ecological environment and high economic benefits. China’s agricultural production is being applied, such as: rice-fish symbiosis system, food-pig-fat system, fat-algae-fish system, manure-biogas-fertilizer system, Are all ecological engineering that have played a very good economic benefit in production and have aroused the widespread concern of producers and scientists.
