摘　　要：运用层次分析法（AHP），在对被破坏土地调查和预测的基础上对焦作市新河矿区待复垦土地资源的适宜性进行了评价。结果表明，新河矿区土地破坏程度较轻，以恢复原土地利用类型为主、多宜性土地优先复耕为原则，宜农地（评价分值在80分以上）面积为814．64hm^2，土地质量好，土壤保水保肥能力强，地下水源充足，灌溉保证程度高；宜园地（评价分值在60-80分）面积为42．25hm^2，土地质量适中，土壤有一定保水保肥能力，地下水源较充足，但缺乏灌溉设施，农业利用时需要采取一定改良措施。The suitability of needed reclamation land in Xinhe mining area, Jiaozuo city was evaluated by AHP based on survey and forecast of destroyed lands. The results showed that the destroyed degree of lands in Xinhe mining area was slight, the area of suitable to farmland with good land quality, strong ability of water and fertilizer preservation;enough underground water source and higher irrigation level was 814.64 hm^2. The area of suitable to garden land with middle soil quality, certain ability of water and fertilizer preservation, enough underground water source without irrigation facilities was 42. 25 hm^2 and some improvement measures should be used when the suitable to garden land was used in agricultural utilization.
