【摘要】：城镇化是人口、经济、社会、生态和空间等多因素共同作用的结果,兼顾"质"与"量"、"时"与"空"的协调发展至关重要.该文以安徽省为研究区,从人口发展、经济发展、社会发展、生态环境、城乡统筹发展及开放程度6个维度构建城镇化质量评价指标体系,借助构建的基于粒子群优化投影寻踪和系统聚类相结合的城镇化质量测度的新方法,对安徽省16个地级市2005年、2010年、2014年的城镇化质量进行测度.研究结果表明:1)2005年~2014年安徽省城镇化质量不断提升,近10年的增长幅度为10.35%,3个研究时点各地级市城镇化质量的首末位差(3.375 4、3.2757、3.029 5)、标准差(0.825 8、0.804 0、0.732 7)和变异系数(54.19%、51.81%、43.57%)显示各地级市城镇化质量存在差距但逐渐缩小.2)根据城镇化质量投影值的变化将安徽省城镇化质量分为高质量、较高质量、中等质量、较低质量、低质量5种类型,空间上具有一定的聚集特征,呈现"两高两低"空间分布格局.3)经济发展、社会发展、生态环境是安徽省城镇化质量发展的主要驱动因素.研究结果对制定安徽省城镇化发展战略、促进16地市城镇化协调发展具有重要的参考意义.
[Abstract]:Urbanization is the result of many factors such as population, economy, society, ecology and space. It is very important to coordinate the development of "quality" and "quantity", "time" and "space". Taking Anhui Province as the research area, this paper constructs the evaluation index system of urbanization quality from the six dimensions of population development, economic development, social development, ecological environment, urban and rural overall development and the degree of openness. With the help of a new method of urbanization quality measurement based on particle swarm optimization projection pursuit and systematic clustering, this paper measures the urbanization quality of 16 prefecture-level cities in Anhui Province in 2005, 2010 and 2014. The results show that the quality of urbanization in Anhui Province from 2005 to 2014 is constantly improving. In the past 10 years, the growth range is 10.35, the difference between the first and last position of urbanization quality in each prefectural city is 3.375 4 / 3.2757 / 3.029 5, the standard deviation is 0.825 8 / 0 / 0.8040 / 0 / 0.732 7) and the coefficient of variation is 54.19 / 51.81/ 43.577.It shows that there is a gap in the quality of urbanization in each prefectural city, but it is gradually narrowing down. (2) according to the urban area, the urbanization quality of each prefectural city has a gap but gradually shrinks. The change of projection value of urbanization in Anhui Province divides the quality of urbanization into high quality. There are five types of high quality, medium quality, low quality and low quality. They have a certain gathering feature in space, showing "two high and two low" spatial distribution pattern. 3) Economic development and social development. Ecological environment is the main driving factor of urbanization quality development in Anhui Province. The research results have important reference significance for formulating the urbanization development strategy of Anhui Province and promoting the coordinated development of urbanization in 16 cities.
