摘　　要：提出了影响复垦土地生产力的三要素：环境要素、土壤要素与投入要素，并讨论了三要素之间的关系；分析了复垦土地生产力系统形成耗散结构的条件，导出了复垦土地生产力变化的动力学方程（ＥＳＩＤＥ），提出了投入产出比已知和未知两种情况下的复垦土地生产力系统状态的熵流评价模型（ＥＥＭ）Three key factors, i e., environmental factor, soil factor and investment factor, which influence reclaimed land productivity are posed, and the relationship of three factors is analyzed. Dynamic equation of reclaimed land productivity (ESIDE) is conducted after analyzing the conditions for forming dissipation structure in reclaimed land productivity system. Different entropy exchange models (EEMs) suitable for IO certain and uncertain are developed respectively. By means of EEMs,positive and negative impact of mining on land use can be evaluated.
