【摘要】:首先引入定量識(shí)別城市擴(kuò)展模式的城市擴(kuò)展面積指數(shù),結(jié)合象限方位法和緩沖帶法分析空間擴(kuò)展特征;其次在柵格尺度構(gòu)建空間Logistic回歸模型,研究不同時(shí)間序列城市增長(zhǎng)驅(qū)動(dòng)機(jī)制。結(jié)果表明:①1990-1995年天津城市擴(kuò)展以主城區(qū)填充式、環(huán)城四區(qū)外延式為主,填充式和外延式主要分布在Ⅲ、Ⅶ、Ⅷ象限與16、56、104km緩沖帶,距公路較近易發(fā)生擴(kuò)展,道路沿線的城市擴(kuò)展空間輻射范圍廣;②1995-2000年天津環(huán)城四區(qū)、塘沽、大港少量填充式擴(kuò)展,集中在Ⅶ、Ⅷ象限與96~112km緩沖帶,城市擴(kuò)展與到城市用地距離顯著負(fù)相關(guān),主城區(qū)高密度建設(shè)用地抑制環(huán)城四區(qū)城市擴(kuò)展;③2000-2005年天津城市擴(kuò)展活躍,以主城區(qū)填充式、環(huán)城四區(qū)外延式、塘沽和大港"衛(wèi)星城"式為主,主要分布在Ⅲ、Ⅶ、Ⅷ象限,填充式和外延式集中在8~24km緩沖帶而"衛(wèi)星城"式集中在16~56km緩沖帶,城市擴(kuò)展與到公路距離有最顯著負(fù)相關(guān)性,道路建設(shè)是推動(dòng)天津主城區(qū)、環(huán)城四區(qū)、武清及靜海城市擴(kuò)展主要驅(qū)動(dòng)力,其次距城市用地較近易發(fā)生城市擴(kuò)展,塘沽與大港分散的城市用地帶動(dòng)周邊城市擴(kuò)展。以上結(jié)果反映出1990-2005年天津城市擴(kuò)展時(shí)空分異顯著,西北-東南是城市空間擴(kuò)展主要走向;城市擴(kuò)展影響因素多元化,公路建設(shè)是主導(dǎo)驅(qū)動(dòng)因子,交通區(qū)位優(yōu)越地區(qū)最易發(fā)生城市擴(kuò)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,
