摘要
从农业技术系统熵产生提出了农业技术自然科学的合理性原则: 最小作用量原理;物质人工输入与输出平衡原理和logistic 规律, 以期用最小代价获取负熵。技术和环境组成不同的生态网络, 因此有必要构建一门新学科—农业技术生态学来研究农业技术的负效性, 它是通向可持续发展农业的桥梁。
From the point of agrotechnical system entropy, natural scientific principle of agrotechnical reasonableness was posed in this paper, such as the least action principle, the artificial input and its output keep in balance stage and obey the logistic law in order to gain more negentropy by minimal artificial price. Farming techniques would cooperate harmoniously with the environment as a whole ecological web, so it is necessary to establish a new science——agrotechnical ecology for the studies of negative effects. It is a bridge towards the development of sustainable agriculture.
