Abstract:Cities have entered a transitional stage from incremental development to intension existent development. Beyond demolition and reconstruction, revitalising existing functioning neighbourhoods to make them more liveable and resilient while balancing their inter-relationships is an important topic in sustainable urban planning and governance. This paper puts forward a conceptual model for a “hybrid urban morphologies community” (HUMC) and explores its collective environmental performances. Taking the Hubei HUMC as a case study site, the paper examines its diverse temporal-spatial environmental performances by adopting on-site observation and measurement, focusing on local micro-scale climate, thermal comfort, and pedestrian ventilation capacity. Results reveal that none of the eight examined morphological patterns in Hubei HUMC consistently exhibited satisfactory environmental performance across all time periods in a typical summer day. Each morphological pattern presented varied merits and drawbacks during specific time periods. These morphological patterns together create an environmental complementary and form a synergetic socio-ecological system under the shared environment mechanism, which enables residents to have continuous outdoor habitation. Correlation and regression analyses illustrated that SVF, TSF, GCR, and GSA were the most critical of the “adaptable” urban morphological indicators (UMIs) that influenced urban outdoor environmental performances. Ultimately, soft intervention is advocated through temporarily rather than permanently adjusting these “adaptable” UMIs to ameliorate spaces with unsatisfactory environmental performances during the specific time periods. The proposed HUMC provides a reference model for urban management zoning and establishment of resilient self-adaptive urban communities.
