Abstract:

In order to systematically study the differentiation of residential space from the perspective of the ecological niche theory, this paper constructs a residential niche evaluation model based on the extended ecological niche theory, and empirically analyzes the differentiation of residential space in the main urban area of Lanzhou City, a central inland city in northwest China. The results show the following key points: (1) The residential space niche shows a high ecological niche in the core downtown area, which gradually decreases toward the outer circle or fan. Residential potential not only reflects the agglomeration and diffusion function of location, but also reflects its filtering and exclusion function. To some extent, the spatial differentiation of residential state can reflect the differentiation of residential space, and it can also reflect the relative positions and spatial patterns of groups with different socio-economic attributes. (2) The streets with better potential, living state and living ecological niche tend to occupy the advantage of urban location, has a long history and culture, improved infrastructure, public services and good natural humanities environment, especially with universities, research institutes and other units located among them, the residents’ cultural level and the income level is relatively high. And the streets of poor potential, living state and living ecological niche are often located in the city edges, where the geographical condition is poor, with poor infrastructure, weak public services, uneven terrain, and inconvenient transportation, the natural humanities environment is relatively poor, the residents mostly in urbanized, shed tranform project households and low-income residents and the low-income groups are generally with low cultural level. Finally, some policy suggestions are put forward to regulate the differentiation of urban residential space. The research results not only enrich residential space differentiation theory and the associated corpus of case studies, but also provide important reference value for the high-quality development of inland central cities in northwest China.
