Abstract:

The strategy of "new urbanization" calls for a harmonious coexistence between man and nature and a path of green, low-carbon, efficient and intensive sustainable development. This paper constructs an evaluation index system of urbanization and resource-environmental pressure, and applies the grey correlation degree and coupling coordination degree model to study the space-time coupling process of urbanization process and resource environment pressure in Liaoning. The results show that: (1) from 1996 to 2017, the urbanization level of Liaoning province has been increasing, and the pressure of resources and environment has been decreasing. The coupling of the two has always been at the antagonistic stage, and the coupling coordination relationship has undergone a process of transformation from low coordination to medium coordination and then to high coordination. The built-up area is the most typical limiting factor of urbanization in Liaoning province, and land resource occupation is the most typical limiting factor of resources and environment. (2) There is a large spatial difference in the urbanization level of 14 cities in Liaoning province. Shenyang and Dalian are always at the forefront of urbanization development within the province, while Chaoyang and Tieling are relatively backward. The degree of coupling coordination between urbanization and pressure of resources and environment presents the characteristics of high cities in the southeast and low cities in the northwest, which presents a certain spatial correspondence with the development level of urbanization.

摘要:

“新型城镇化”战略要求人与自然和谐共生,走绿色低碳、高效集约的可持续发展道路。构建城市化与资源环境压力的评价指标体系,并应用灰色关联度和耦合协调度模型,对辽宁省城市化进程与资源环境压力的时空耦合过程进行研究。结果表明:1996—2017年辽宁省城市化水平不断提高,资源环境压力呈下降趋势;两者的耦合作用一直处于颉颃阶段,耦合协调关系经历了低度协调向中度协调再向高度协调转变的过程;建成区面积是最典型的城市化限制因素,土地资源占用是最典型的资源环境限制因素。辽宁省14地市城市化水平的空间差异较大,沈阳、大连始终居于省内城市化发展前列,而朝阳和铁岭较为落后;城市化与资源环境压力的耦合协调度在空间上呈现出东南高、西北低的特点,这与城市化发展水平呈现一定的空间对应关系。
