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.
