摘要
就东北黑土区中低产田的等级、类型划分以及治理措施进行了简要综述。东北黑土区中低产田可划分为高中低三个等级，其划分标准为高产田：粮食产量〉6000 kg·hm^-2，中产田：粮食产量4000-6000 kg·hm^-2，低产田：粮食产量〈4000 kg·hm^-2。中低产田包括7种类型：侵蚀型、易涝型、干旱型、盐碱型、风沙型、瘠薄型和低温及其它类型。提出了中低产田的治理对策与措施，分析了中低产田的增产潜力为112.4亿kg（2010年）-161.8亿kg（2030年）。
The degree,types and comprehensive control strategies of mid-low yield land in northeast mollisols were mainly introduced. Mid-low yield land of northeast mollisols could be classified to high,middle and low three degrees. The standards of classification was that high yield land yield〉6 000 kg·hm^-2,middle yield land was 4 000 -6 000 kg·hm^-2 ,low yield land was 〈4 000 kg·hm^-2. Mid-low yield land could be classified in to 7 types ineluding erosion type, flooding type, drought type, saline-alkali type, aeolian type, impoverish soil type and low temperature and other types. Appropriate comprehensive control strategies were used and analyzed the potential yield of mid-low yield land would be from 1 1240 million per hactare（2010 year）to 16180 million per hactare（2030 year）.
