Taking Chaoyang District of Beijing as an example, this paper identified Production-Living-Ecological Space in rural-urban fringe, and described the spatial pattern evolution with the help of transformation matrix and spatial analysis tools. On this basis, the spatial metrology models were selected to analyze the driving factors of space conversion. The results show that, 1) from 2005 to 2020, according to the spatial order from near to far from the city center, the scale of Production Space was reduced and concentrated, the Ecological Space formed a green ecological landscape belt in the periphery of Beijing, the Eco-Agricultural Production Space and the Life-agricultural Production Space were rapidly reduced, and the Living-Non-farm Production Space was rapidly expanded in the point-line-plane order. 2) From 2005 to 2020, the shift of Production Space to Living-Non-farm Production Space was always the main direction of conversion, the Living-Non-farm Production Space continued to gain a large amount of inflow, and finally became the largest space type in the study area. 3) From 2005 to 2010, driven by population, economy and industrial factors, the Production Space converted into Living-Non-farm Production Space, and Eco-Agricultural Production Space converted into Production Space. From 2010 to 2015, population and economic factors further drove Production Space to Living-Non-farm Production Space. From 2015 to 2020, driven by the policy and industrial factors, the Production Space converted into Living-Non-farm Production Space or Ecological Space.

以北京朝阳区为例, 识别城市边缘区的“三生”空间, 并借助转换矩阵和空间分析工具刻画“三生”空间格局演变。在此基础上, 优选空间计量模型, 分析“三生”空间转换的驱动因素, 得到如下结果。1) 2005—2020年, 按照距离市中心由近及远的空间顺序, 生产空间规模缩减并集聚, 生态空间在城市外围形成绿色环带, 生态–农业生产空间和生活–农业生产空间快速缩减, 生活–非农生产空间按照点–线–面顺序快速扩张。2) 2005—2020年, 生产空间转为生活–非农生产空间是首要转换方向, 生活–非农生产空间持续获得大量转入, 已成为区域内占比最大的“三生”空间类型。3) 2005—2010年, 在人口、经济与产业因素的驱动下, 生产空间转为生活–非农生产空间, 同时生态–农业生产空间转为生产空间; 2010—2015年, 人口与经济因素进一步驱动生产空间转为生活–非农生产空间; 2015—2020年, 在政策和产业因素的驱动下, 生产空间转为生活–非农生产空间或生态空间。研究结果证实城市边缘区“三生”空间格局演变存在距离和政策驱动效应。
