摘要:

［目的］为了细化县级尺度土地利用转型研究以及探讨“三线”范围内外土地管制对策。［方法］以2005年、2010年、2015年3期海阳市土地利用变更调查成果为基础，从生产、生活、生态功能角度构建土地利用分类体系，运用土地利用转移矩阵、聚类分析和重心转移模型，定量刻画海阳市土地利用时空格局。［结果］（1）基于“三生”功能将土地利用类型划分为3个一级类、9个二级类。（2）2005—2015年，一级类中，生产用地减少，生活用地增加，生态用地稳定； 从转入转出角度，主要表现为生态用地转出为生产用地、生产用地转入为生活用地。二级地类中，农业生产用地既是主要转出者，也是主要转入者，工矿生产用地通过转出，废弃地利用效率得到提升； 城镇生活用地转入势头逐步得到遏制； 水域生态用地的转入使生态环境有所改善，其他生态用地通过开发而得到有效利用。（3）从重心移动方向来看，“三生”用地的重心分别向西北、东南、西南方向偏移； 从重心移动距离来看，生活用地＞生态用地＞生产用地。（4）依据“三线”范围内外土地利用情况，提出差别化“三生”用地管制对策。［结论］海阳市土地利用转型总体趋势符合“十三五”社会经济发展定位，“三生”用地管制对策为土地供给侧改革奠定基础。

Abstract:

This research is intended to refine the research on county level land use transformation and explore the land control countermeasures within and outside the "three line" area. Based on the land use change survey results of Haiyang city in 2005, 2010, and 2015, the land use classification system was constructed from the perspectives of production, living, and ecological functions, and the land use transfer matrix, cluster analysis, and center of gravity were used. Then, the transfer model was used to quantitatively characterize the spatial and temporal pattern of land use in Haiyang City. The results were showed as follows. (1) Based on the "production living ecological" function, the land use types were divided into three first class and nine second class. (2) From 2005 to 2015, in the first class category, production land decreased, living land increased, and ecological land was stable; from the perspective of transfer in and out, the main manifestations were the transfer of ecological land to production land, and the transfer of production land to living land. In the second level land category, agricultural production land was both the main transferor and the main transferee. Through the transfer of industrial and mining production land, the utilization efficiency of abandoned land had been improved; the transfer of urban residential land had been gradually curbed; the transfer of ecological land in waters had improved the ecological environment, and other ecological land had been effectively used through development. (3) From the direction of the center of gravity movement, the center of gravity of the " production living ecological" land was shifted to the northwest, southeast, and southwest respectively; from the distance of the center of gravity movement, living land> ecological land> production land. (4) Based on the land use situation within and outside the "three line" area, it put forward differentiated "production living ecological" land control measures. The general trend of land use transformation in Haiyang city is in line with the socio economic development orientation of the "Thirteenth Five Year Plan", and the "production living ecological" land use control measures lay the foundation for land supply side reform.
