【摘要】:首先引入定量识别城市扩展模式的城市扩展面积指数,结合象限方位法和缓冲带法分析空间扩展特征;其次在栅格尺度构建空间Logistic回归模型,研究不同时间序列城市增长驱动机制。结果表明:①1990-1995年天津城市扩展以主城区填充式、环城四区外延式为主,填充式和外延式主要分布在Ⅲ、Ⅶ、Ⅷ象限与16、56、104km缓冲带,距公路较近易发生扩展,道路沿线的城市扩展空间辐射范围广;②1995-2000年天津环城四区、塘沽、大港少量填充式扩展,集中在Ⅶ、Ⅷ象限与96~112km缓冲带,城市扩展与到城市用地距离显著负相关,主城区高密度建设用地抑制环城四区城市扩展;③2000-2005年天津城市扩展活跃,以主城区填充式、环城四区外延式、塘沽和大港"卫星城"式为主,主要分布在Ⅲ、Ⅶ、Ⅷ象限,填充式和外延式集中在8~24km缓冲带而"卫星城"式集中在16~56km缓冲带,城市扩展与到公路距离有最显著负相关性,道路建设是推动天津主城区、环城四区、武清及静海城市扩展主要驱动力,其次距城市用地较近易发生城市扩展,塘沽与大港分散的城市用地带动周边城市扩展。以上结果反映出1990-2005年天津城市扩展时空分异显著,西北-东南是城市空间扩展主要走向;城市扩展影响因素多元化,公路建设是主导驱动因子,交通区位优越地区最易发生城市扩展。
[Abstract]:Firstly, the urban expansion area index of the urban expansion mode is introduced, and the spatial expansion characteristics are analyzed by combining the quadrant bearing method and the buffer band method; secondly, the spatial logistic regression model is constructed on the grid scale to study the urban growth driving mechanism of the different time series. The results show that, in 1990-1995, the urban expansion of Tianjin is mainly filled in the main urban area, the four-zone extension type of the ring city is the main type, and the filling type and the epitaxial type are mainly distributed in the 鈪,
