In order to master the situation and spatial-temporal characteristics of middle and low yieldingfields in the northeast region, Heilongjiang, Jilin and Liaoning province were chosen as research areas, changes inarea and spatial-temporal distribution of middle and low yielding fields in 1990~2010 were analyzed using produc-tion method. The results showed that the middle field area increased by 972 000 hm², low-yielding fields area de-creased by 1 111 000 hm² from 1990 to 2010. Middle field distribution area expanded from the central to the south-west, most of the low yielding fields distributed in the northern region, few of them scattered in the hilly region of Li-aodong that showed a decreasing trend. There are many factors lead to spatial-temporal variation of the middle andlow yielding fields, which including natural disaster risk, agro-production factors input and agricultural technology.In the end, some measures to improve the quality of the middle and low yielding fields and promote sustainable useof farmland resources were put forward, such as improving agricultural production conditions, using land scientifical-ly, monitoring the quality of cultivated land dynamically and regulating the industrial agriculture.
