摘要
经济、社会、生态三个系统的和谐共生,对地区可持续化发展、国土资源合理配置有重大影响。将经济、社会、生态三系统单独分开进行耦合协调,并加入相对发展度模型,模拟计算环鄱阳湖生态经济区7市在2003~2019年各系统的耦合协调度和相对发展值,在此基础上对城市时空演变格局进行系统分析。结果表明:时序上,经济、社会、生态系统的耦合协调度总体呈波浪式上升,协调类型从拮抗期的中度失调变为协调期的高度协调,实现了“拮抗—磨合—协调”的跨越,2019年所有城市实现零失调,城市间略有差异但差别不大,各系统逐步趋于优化;空间上,耦合协调发展趋势总体呈现“东快西慢”、“东北—西南”两级发展较快,鄱中地区发展增速较为匀速平稳,整体趋势处于协调状态;系统间的相对发展值明显有差异,总体呈“社会滞后—经济社会滞后—生态滞后”的变化趋势。虽然这17年三系统的耦合协调水平值整体提高,但系统间矛盾依然是限制整体可持续发展的关键问题。据此建议加强产业结构改革,注重各系统的生态效益,同时提高土地的集约利用水平,确保土地的合理利用。
The harmonious coexistence of economic,social and ecological systems has a significant impact on regional sustainable development and rational allocation of land and resources.The economic,social and ecological systems are separately coupled and coordinated,and the relative development degree model is added to simulate and calculate the coupling coordination degree and relative development value of each system of 7 cities Ecological Economic Zone around Poyang Lake from 2003 to 2019.On this basis,the urban temporal and spatial evolution pattern is systematically analyzed.The results show that:in terms of time sequence,the coupling and coordination degree of economic,social and ecological systems generally rises in a wave,and the coordination type changes from moderate imbalance in the antagonistic period to high coordination in the coordination period,realizing the leap of"antagonism running in coordination".All cities will achieve zero imbalance in 2019,with slight differences among cities,but little differences,and each system tends to be optimized gradually;Spatially,the coupling and coordinated development trend generally presents a two-level development pattern of"fast in the east and slow in the west"and"northeast southwest".The development growth rate of Pozhong region is relatively uniform and stable,and the overall trend is in a coordinated state;There are obvious differences in the relative development values between systems,and the overall trend is"social lag-economic and social lag-ecological lag".Although the coupling and coordination level of the three systems has improved as a whole in the past 17 years,the contradiction between systems is still the key problem limiting the overall sustainable development.Therefore,it is suggested to strengthen the reform of industrial structure,pay attention to the ecological benefits of various systems,and improve the level of intensive land use to ensure the rational use of land.
