| 摘 要： | 从生态角度考虑天津市扩展性建设适应情况,文中采用最小累计阻力模型来建立天津市的生态安全格局的阻力值,进而用发展阈限的概念,确定出不同等级的安全格局。利用GIS软件绘制出了天津城市扩展安全格局,从定量和动态的角度为天津市的城市发展提供了规划依据。

| Abstract: | Considering the adaptable question of expanded building from ecological aspects,this article adopted minimum cumulative resistance to build the resistance value of ecological security pattern in Tianjin city,and used the means of development limen to confirm the different grades security pattern.From the quota and the dynamic stratification plane,Tianjin's expansion security pattern was drawn up using the GIS software which provided planning basis to local urban development direction. |
