摘　　要：生态环境受损价值的科学界定是当前生态补偿机制研究的重点和难点之一。以采煤塌陷导致的土地退化形式——水改旱为研究对象,通过文献总结分析和入户调查等方式,从水循环过程和保护水田生态环境的角度,分析了水田与水改旱生态系统两者之间水要素的差别,在此基础之上,引入"虚拟水贸易"理论来确定水改旱生态补偿标准的可行性。虚拟水生态补偿标准不仅能体现水田生态受损价值,而且能够协调平衡补偿客体之间的利益。该方法为采煤塌陷区农田生态损害生态补偿机制和政策制定提供参考。To scientificaUy determine the cost of eco-environmental damage is a locus and difficult issue m resear- ches of ecological compensation. In this paper we take the transformation of paddy field into dry land （ a pattern of land degradation caused by coal mine collapse） as research object, and analyse the changes of water factors （ in terms of water cycle and eco-protection） from paddy field to dry land through literature review and household sur- vey. On this basis, we introduce the concept of virtual water trade to determine the feasibility of eco-compensation standard for paddy field transferring into dry land. This research could be a reference for the eco-compensation mechanism and decision-making in coal mining collapse areas.
