| 摘 要： | 农田生态系统是由相互联系、相互依存的生物因子与非生物因子,经由能量投入产出,不断循环、转换而形成的人工生态系统在进行能量分类以及投入产出效益分析的基础上,力求达到以最少的投入获得最大的经济效益和生态效益。并对提高农田生态系统投入产出效益的途经和措施进行了探索。

| Abstract: | The field ecosystem is an artificial ecosystem of biological factor: and non-biological factors contacting with each other and dependent on each otner, and with an input-output, uncearing cycle and transter of energy in the system. It tells how to get maximum economy benefit and ecological benefit with minimum input on the basis of energy classifying and benefit analysis of input-output. This PaPer also explores the ways and the measure to improve the input-output benefit of field ecosystem |

| Keywords: | field ecosystem energy- input energy - output benefit |
