【摘要】：在人地关系日益紧张的背景下,城市发展所需的建设用地保障将面临困境,土地资源的约束已经扩展到城市建设用地对经济发展的约束。基于长春市土地资源整治潜力中可新增耕地数量,反推城市可新增建设用地,将其与BP神经网络预测的城市建设用地的合理需求进行对比,分析未来5—10年长春市建设用地的保障程度。研究结果表明,基于土地整治可新增建设用地角度,2020年长春市主城区城市建设用地缺口为68km2,2025年长春市城市建设用地缺口达110km2,如果未来5—10年城市建设用地都通过新增建设用地来满足,长春市将出现土地供给不能满足城市建设用地发展需求的局面,建设用地保障能力严重不足,城市存量建设用地挖潜势在必行。
[Abstract]:Under the background of the increasingly tense relationship between man and land, the construction land security for urban development will face difficulties, and the constraints of land resources have been extended to the constraints of urban construction land on economic development. Based on the amount of arable land that can be added in the potential of land resources regulation in Changchun, the urban construction land can be added back, and compared with the reasonable demand of urban construction land predicted by BP neural network. This paper analyzes the guarantee degree of construction land in Changchun in the next 5-10 years. The results show that Based on the angle that land renovation can be added to the construction land, the gap of urban construction land in Changchun is 68km2 in 2020 and 110km2 in 2025. If in the next 5-10 years, the urban construction land will be satisfied by new construction land. Changchun will have the situation that the land supply can not meet the development demand of urban construction land, the construction land security capacity is seriously insufficient, and it is imperative to tap the potential of urban stock construction land.
