| 摘 要： | 为了探究兰西城市群城市高质量发展与区域生态环境质量的相互关系问题,以兰州-西宁城市群为对象,以生态城市理念下的高质量发展为目标,基于多元数据与GIS空间分析方法,定量评价了兰西城市群城市发展质量与区域生态敏感性水平,及其二者的耦合协调关系。结果表明:(1)城市发展质量等级的空间分布呈现明显的中心外围结构与双核结构特征,形成了综合发展型、社会保障型、经济发展型、环境友好型与发展滞后型5类主导类型。(2)区域生态敏感性呈现集中连片与分散破碎两类空间分布特征,不仅不同等级的生态敏感区域其规模显著不同,而且同一等级的敏感性规模在不同县(区)间亦显著不同。(3)不同等级类型耦合协调度的分布规模差异显著,空间上呈现东西部高且中南部破碎的分布特征,与生态敏感性空间分布具有较明显的一致性。兰西城市群城市发展质量差异明显,生态环境复杂多样,区域耦合协调发展程度不一,应当立足于当地城市质量发展的主导类型与区域生态环境状况,实施精准对策,推动区域协调发展。

| Abstract: | In order to explore the relationship between the high-quality development and the regional ecological environment quality of Lanzhou-Xining urban agglomeration,with respect to high-quality development in terms of the concept of ecological city,Lanzhou-Xining urban agglomeration was taken as the research sample,multivariate data and GIS spatial analysis method were used to evaluate the urban development quality and regional ecological sensitivity level quantitatively.Moreover,the coupling coordination between urban development quality and regional ecological sensitivity was analyzed.The results show that:(1)the spatial distribution of urban development quality grade in Lanzhou-Xining urban agglomeration presents the obvious characteristics of center-periphery and dual-core structure,and five major types such as comprehensive development type,social security type,economic development type,environment-friendly type and development lagging type have formed;(2)the regional ecological sensitivity of Lanzhou-Xining urban agglomerations shows two spatial distribution characteristics such as scattered and fragmented patterns and centralized contiguous condition patterns;not only is the scale of ecological sensitive areas of different grades significantly different,but the sensitivity scale of the same level is also significantly different among different areas;(3)the spatial distribution characteristics of coupling coordination degree are significantly different in Lanzhou-Xining urban agglomeration,showing high degrees in the east and west and scattered patterns in the central south,which is consistent with the spatial distribution of ecological sensitivity.All in all,there are obvious differences in the quality of urban development in Lanzhou-Xining urban agglomeration,and the ecological environment is complex and diverse,and the degrees of regional coupling and coordinated development are different.Therefore,the correct countermeasures should be implemented to promote regional coordinated development in terms of the major types of regional quality development and the regional ecological environment. |
