- 摘要:
- 为了厘清资源型城市开发强度与生态承载力的协同发展关系及交互作用机理,选取马鞍山市为典型实证案例,通过构建国土开发强度与生态承载力综合评价指标体系,借助耦合协调度模型、探索性空间数据分析方法和地理加权回归模型,揭示了资源型城市国土开发强度与生态承载力耦合发展的时空特征及其驱动要素。结果表明:(1)2008—2018年样本区域国土开发强度由0.215 6快速上升至0.538 6,空间异质特征逐步显现,生态承载力由0.420 2平稳上升至0.489 5,空间差异不大且基本保持稳定;(2)国土开发强度与生态承载力耦合协调度保持连续上升的趋势,由中度失调阶段逐步向低度协调阶段转变,整体呈现中部高两侧低的分布格局,且空间集聚态势愈加显著,冷热点区分布较为稳定;(3)国土开发强度与生态承载力耦合协调发展的驱动要素时空差异明显,主次顺序依次为产业转型、经济发展、政府调控、资源集聚。基于上述解读,提出了促进国土开发强度与生态承载力协调发展的对策建议。
- Abstract:
- In order to clarify the collaborative development relationship and interaction mechanism between resource-based city development intensity and ecological bearing capacity, the spatiotemporal characteristics and driving factors of coupling development intensity and ecological bearing capacity of resource-based cities were revealed by constructing a comprehensive evaluation index system of land development intensity and ecological bearing capacity, and by means of coupling coordination degree model, exploratory spatial data analysis method and geographic weighted regression model. Maanshan City was selected as a typical case study. The results show that:(1)from 2008 to 2018, the intensity of territorial development in the sample area increased rapidly from 0.215 6 to 0.538 6, and the spatial heterogeneity gradually emerged; the ecological bearing capacity increased steadily from 0.420 2 to 0.489 5, with little spatial difference and basic stability;(2)the coupling between territorial development intensity and ecological bearing capacity coordination degree kept a continuous upward trend, and gradually changed from moderate imbalance stage to low coordination stage, showing the overall distribution pattern of high and low sides in the middle; the spatial agglomeration trend was more significant, the distribution of cold and hot spots was more stable;(3)spatial and temporal differences of driving factors for coordinated development of land development intensity and ecological bearing capacity were obvious, the driving role decreased in the order: industrial transformation>economic development>government regulation>resource agglomeration. Based on the above interpretation, some countermeasures and suggestions are put forward to promote the coordinated development of land development intensity and ecological bearing capacity.
