摘要
耕地利用和保护是关系我国国民经济和社会可持续发展的全局性战略问题。针对当前中国耕地利用和保护面临的问题,利用耗散结构理论与熵流模型(EEM),从新的视角并采用新的方法加以研究。研究结果表明,耗散结构理论对耕地利用与保护具有一定的指导意义。最后提出了可行性的政策建议。
Cultivated land protection is tied with the strategies of sustainable social - economic development in China. As to the serious situation that farmlands are using and protecting in China, the theory of dissipative structures and entropy exchange model is employed. The purpose of this study is to analyses the use and protection of cultivated land form new perspectives and by new methods.
