为探寻大渡河各地区城镇化发展滞后的原因,并为发展新型城镇化提供指导,通过构建城镇化水平评价指标体系,运用熵值法、GIS地学空间分析技术、演化树模型等方法,测度城镇化水平和细分城镇化驱动因子模式,总结不同发展模式下地区城镇化水平的演化格局.研究表明:大渡河流域各地区城镇化水平在空间上有较大差异,差距随时间推移不断扩大;演化过程分析显示,城镇化驱动因子不同成为上下游地区城镇化水平差距的重要原因.总结了各类城镇化的动力机制特征,拟为大渡河流域城镇化水平提升提供分类指导. 

The area of the Dadu River Valley has been chosen for the study,with a purpose to build the level of urbanization index system,to measure levels of urbanization,and to summarize the evolution of different development model of urbanization level of the region through dividing industry structure benefits mode in detail.Studies suggest that comprehensive level of urbanization in the Dadu River region has a big difference in spatial distribution of river basin and inter-regional disparities continue to expand over time.From the analysis on evolution process,the difference of urbanization driving factors become important factors of the level of urbanization between upstream and downstream region.We have summed up the dynamic mechanism of all kinds of urban to provide the classification guidance and enhance the level of urbanization in the Dadu River Valley.
