摘要:

探索城镇化与资源环境之间的相互作用与复杂关系具有重要意义。从可持续城镇化视角,构建城镇化发展指数和资源环境压力指数,分析评估了2003-2015年北京市城镇化发展对资源环境压力的影响,借鉴解耦模型进一步研究了北京市城镇化与资源环境压力的耦合关系。结果表明:① 北京城镇化进入了后期成熟阶段,人口、经济和社会城镇化均呈现出较高水平且增速放缓的特征,人口城镇化率从79.05%上升到86.51%。② 资源消耗总量仍在不断增加,而环境污染的治理效果相对较为明显,工业废水、工业固体废物等污染物排放量趋于降低,城镇化发展的资源环境压力总体处于中等水平且呈波动性逐步上升趋势。③ 12年间,北京市城镇化发展与资源环境压力呈现由弱解耦—强解耦—弱解耦—扩张性耦合—扩张性负解耦—强解耦—弱解耦—强解耦的演变轨迹,耦合与解耦关系反复,这种反复体现了城镇化发展与资源环境之间复杂关系及其动态演化特征。资源环境可持续性将是北京建设国际一流的和谐宜居之都的关键瓶颈因素之一。

Abstract:

With the rapid development of urbanization, the waste of resources in new towns and industrial parks and the frequent environmental pollution incidents such as haze and dust storms have caused great pressure on the resources and environment. It is of great significance to explore the interaction and complex relationship between urbanization and resources-environment. Based on the theory of sustainable urbanization, this paper constructs the urbanization index and resources-environmental pressure index, analyzes the influence of urbanization on resources-environmental pressure from 2003 to 2015 in Beijing, and studies the coupling relationship between urbanization and resources-environmental pressure in the city means of decoupling model. The results show that: (1) The urbanization of Beijing has entered a mature stage, and the population, economic and social urbanization all show a high level and a slow growth rate. The urbanization rate rose from 79.05% to 86.51% in 2003-2015. (2) From the intensity and change characteristics of the pressure caused by urbanization on the resources and environment, the total consumption of resources is still increasing, while the effect of environmental pollution control is relatively obvious. The discharge of pollutants such as industrial waste water and industrial solid waste tends to decrease. The resources-environment pressure of urbanization development is generally at a moderate level and fluctuating upward. Before 2008, the environmental pollution index was greater than the resource consumption index. After 2008, the resource consumption index was larger than the environmental pollution index, and the gap between the two showed an increasing trend year by year. Resource consumption gradually became the main factor affecting the increase of environmental resource pressure. (3) In terms of the correlation and change trend between urbanization and resources- environmental pressure, in the 12-year period, the urbanization and resources-environmental pressure in Beijing were characterized by weak decoupling - strong decoupling - weak decoupling - expansive coupling - expansive negative decoupling - strong decoupling - weak decoupling - strong decoupling. The recurrence of coupling and decoupling reflects the complex relationship and dynamic evolution between urbanization and resources-environment. Reducing the pressure on resources and the environment is very important to realize Beijing's goal of building a world-class harmonious and livable capital.
