随着中国快速城市化背景下的农村人口向城市的迁移，中国环渤海地区在过去十年中经历了剧烈的农村宅基地转型（RHLT），特别是在人均农村宅基地（PRHL）方面。本研究的目的是（i）分析RHLT的时空格局，以及（ii）探测2000-2010年环渤海地区RHLT的潜在驱动力和机制。为了实现这些目标，我们收集并栅格化了环渤海地区的高分辨率 Landsat TM 数据、社会经济和自然环境数据。开发了网格尺度和县域尺度的空间计量经济回归模型来检验环渤海地区RHLT的驱动力。结果表明，农村宅基地分布呈现垂直地带性特征，即随着海拔的升高，农村宅基地所占比重逐渐减少，且对坡度的敏感度高于对高程的敏感度。热点分析结果表明，农村宅基地变迁与农村人口迁移的空间错配使得宅基地土地整治的区域差异更加显着，据此区分了四种农村宅基地整理区域类型。作者认为，城镇是连接城乡体系的有效枢纽，在未来推进中国新型城镇化的过程中，最好让农民向城镇迁移，而不是向大城市迁移。为此，有必要进一步完善相关制度和制度。只有这样，才能有序彻底解除外来农民与宅基地的关系，顺利推进农村宅基地整理。 (c) 2015 Elsevier Ltd. 保留所有权利。
With the rural-to-urban migration under China's rapid urbanization, the Bohai Rim of China experienced dramatic rural housing land transition (RHLT) in the last decade, especially in terms of per capita rural housing land (PRHL). The objectives of this study are to (i) analyze the spatio-temporal patterns of RHLT, and (ii) detect the underlying driving forces and mechanism of RHLT in Bohai Rim during 2000-2010. To achieve these goals, we collected and rasterized high resolution Landsat TM data, socio-economic and physical environmental data for the Bohai Rim. Spatial econometric regression models at both grid scale and county scale were developed to examine the driving forces of RHLT in Bohai Rim. The results indicated that the distribution of rural housing land was characterized by vertical zonality, i.e., the proportion of rural housing land decreased gradually with the increase of elevation, and was more sensitive to slope than to elevation. The results of hot spots analysis showed that the spatial mismatch of rural housing land change and rural population migration made the regional differences of RHLT more remarkable, based on which four rural housing land consolidation regional types were differentiated. The authors argue that towns are effective hubs for linking the urban system and rural system, and it is better to get the farmers to migrate to towns instead of big cities in the process of pushing forward China's new-type urbanization in the future. For this, it is necessary to further improve related system and institution. Only by this way can the relationship between out-migrated farmers and rural housing land be orderly and completely removed, so as to smoothly pushing forward rural housing land consolidation.
