Unprecedented urbanisation in China has profoundly reshaped the country's social-spatial structure. Owing to economic suburbanisation and urban redevelopment processes, migrants coming from rural areas are increasingly concentrated in suburbs rather than city centres. Against this backdrop, this paper focuses on residential segregation between migrants and locals, and on geographical (re)structuring between the city centre and suburb. Theil's H Index is used to disaggregate the migrant segregation of each municipality into a within-suburb, a within-centre and a between-centre-suburb component. We use Census data for 258 municipalities in 2000 and 2010; we find that migrant segregation increased in this period. We ascribe this to the increasing segregation of migrants in suburban areas, which offsets the increasingly balanced distribution of migrants between the city centre and suburb. Segregation in city centres also increased slightly in this period. Unexpectedly, less economically developed municipalities, defined by their per capita GDP, tend to be more segregated than their more developed counterparts. Less developed municipalities also have a higher level of suburban employment and housing opportunities in the whole municipality, but feature more segregated suburban spaces and a polarised distribution of migrants between the centre and suburb.

The policy background of the construction of characteristic towns in China and the spatial characteristics of suburban towns were studied. The opportunities and challenges of the construction of characteristic towns in the suburbs under the background of new urbanization were discussed. And appropriate planning strategy for the construction of characteristic towns in the suburbs was explored. [ABSTRACT FROM AUTHOR]

Both "Healthy China" and "Healthy Shanghai" programs require construction and development of community public health services. Taking Jinshan District in Shanghai as a case study, this paper evaluates the status quo of community health services from the "demand-supply" perspective, and finds a remarkable difference in the needs among different age groups, a big gap between urban and rural areas in the coverage degree of facilities, and different challenges for public service at the "prevention -- treatment -- health care" stages. It further puts forward several planning strategies involving (1) specific service supply based on different age groups, (2) "15-minute health service cycles" in both urban and rural communities, (3) adjustment of facilities to local conditions, and (4) promoting the quality of health services. Furthermore, it discusses in-depth issues underlying planning policies, such as the innovation of service content, the integration of different plans, and the cultivation of health service needs.

[Display omitted] • A framework of suburb sponge city construction that weighs subjective and objective is proposed. • The EIRSA methodology balanced the important ecological service and residents' basic needs clearly. • The MCDM method is conducive to optimizing the construction of sponge city. • The research is a feasible strategy to build a sponge city that can improve residents' well-being. The construction of the sponge city can effectively alleviate the problems of urban waterlogging and pollution and promote the city's sustainable development. However, few studies on sponge city construction take into account both natural background conditions and resident satisfaction. This study considers both physical and psychological benefits and presents a new integrated theoretical framework to improve urban runoff quality and the well-being of residents. The developed framework consists of two parts: sponge city control space identification and optimization design. The control space suitable for sponge city construction was identified, using the Eco-Importance-Resident Satisfaction Analysis (EIRSA) methodology, and the relationship between the basic needs of suburban residents and the current ecosystem service capacity was explored. The Multi-Criteria Decision Making (MCDM) method was used to optimize the design of the identified control space. The resident subjective visions and sponge city construction goals were used to determine the construction area and type of LID using GIS and the Storm Water Management Model (SWMM). The proposed framework was then applied to a suburb of Huizhou City, China, as a case study. This study analyzed the physical and psychological benefits of sponge city design schemes with different rainfall scenarios (S1, S2, S3, and S4) for the LID construction project. The results identified this scheme had met 90% or more of the region's volume capture ratio of annual rainfall constraints. Furthermore, >60% of the respondents were content with our planning scheme, with 21% being extremely satisfied, compared to only 2.1% satisfied, and 0.7% very satisfied. Considering the trade-off between ecological importance and resident satisfaction, it is a feasible strategy to build a sponge city that can improve residents' well-being in the future. The findings of this paper provide a detailed decision-making basis for the construction of sponge city in suburban areas. [ABSTRACT FROM AUTHOR]

Suburban Chinatowns are intriguing subjects for study and comparison. These ethnic suburbs, or ethnoburbs, have emerged to coexist or compete with the older downtown Chinatowns traditionally found in American central cities. Their growth since the 1960s challenges many traditional assumptions regarding the spatial and cultural assimilation of immigrants in U.S. society, namely that ethnicity would decline with the geographic and socioeconomic mobility of immigrants from the inner city into the suburbs. We examined recent growth trends in the Chinese ethnoburb of the San Gabriel Valley region of Greater Los Angeles, through analysis and mapping of U.S. Census data, and discovered ethnic persistence rather than spatial and cultural assimilation. We also discovered the ethnoburb is differentiated between a lower-class core and two middle-to-upper class fringe districts. Though there is some linguistic assimilation on the northwest fringe, the majority of the ethnoburban population continues to speak Chinese. Linguistic isolation is not a barrier to achieving a higher socioeconomic class position in the Chinese ethnoburb of Los Angeles. [ABSTRACT FROM AUTHOR]
