以东北地区为例，对中国欠发达地区土地利用变迁特征进行了测度，并探讨了其变迁机制。研究发现，东北地区近20年（1995-2015年）土地利用变化的主要特征是耕地面积持续扩大，建设用地增长加快，林地面积持续减少。土地，以及未使用的土地。政策主导了中国城市用地的土地利用转型过程。中国城市化土地利用转型是政策引导下的社会生态反馈与政策引导下的社会经济变化相互作用、耦合的结果。前者决定了区域土地利用转型的方向，后者决定了土地利用转型的强度。在土地利用转型过程中，中国城市农业区土地可持续利用面临着政策支持不合理导致的城市建设用地利用效率低下、耕地不合理扩张导致的生态环境恶化、政策不稳定性和政策冲突等严峻问题。为解决这些问题，应加强对地方政府违规用地行为的惩罚和问责。此外，政策制定者应建立土地利用信息公开制度和公众监督机制。政策制定的出发点应从数量增长转向质量提高，从经济效益转向综合效益。
By using Northeast China as example, this study measured the characteristics of the land use transition of underdeveloped areas (UAs) of China and explored the underlying transition mechanism. This study found that, the main characteristics of the land use transition of Northeast China during the last two decades (1995–2015) were continuous expansion of cropland, accelerated growth of construction land, and continuous reduction of woodland and . rassland, as well as unused land. Policies dominate the process of land use transition of the UAs of China. The land use transition of UAs of China is a result of interaction and coupling between socio-ecological feedback under the guidance of policies and socio-economic change under the influence of policies. The former determines the direction of regional land use transition while the latter determines the intensity of this transition. During the process of land use transition, the sustainable use of land of the UAs of China faces several severe issues: inefcient use of urban construction land caused by unreasonable policy support, degradation of the ecological environment caused by irrational expansion of cropland, and both policy instability and policy conflicts. To resolve these issues, punishment and accountability of local governmental violations of land use should be strengthened. Furthermore, a land use information disclosure system and public supervision mechanism should be established by policy makers. The starting point of policy formulation should be shifted from quantity growth to quality improvement as well as from economic benefts to comprehensive benefts.
