试论耕地生产力的开发与可持续发展

Discussion on Exploitation and Sustainable Developmentof Farmland Productivity

本文指出，耕地生产力具有自然生态与社会经济双重属性。开发与提高耕地生产力并使其持续发展的根本在于实现“资源投入－产品产值”的协调互依自动型正反馈过程。耕地生产力的社会实现，取得超额利润是促进耕地系统非平衡相变的启动杠杆，资源投入与调整生产结构是提高耕地生产力的直接途径。

It was pointed out in this paper that the productivity of farmland had charicteristics on both nature and societyThe essence of exploiting the productivity and maintaining its sustainable development was concerned with the process that the input of resources and the value of output reacted on each other in the way of positive feed backAnd the superprofit in the process acted as the lever to upgrade the crop production systemResources input and structure adjustment of the crop production system were effective ways to increase the productivity of farmland
