Under the background of social transformation and space reconstruction, population aging in China is becoming more and more diverse and complex. "Aging before getting rich", a notion in population and economic development, has been a serious threat to sustainable development in China. On the basis of town-and street block-scale data from the Fifth and Sixth National Census in the Yangtze River Delta, we studied spatial distribution characteristics of population aging using global Moran's I and hotspot analysis, and applied the geographical detector technique to explain the spatial heterogeneity of population aging. Several conclusions were drawn. (1) The promotion and replacement of aging coexist. Cluster of aging degree exhibits an increasing trend. Population aging is more severe in suburban areas than urban areas.(2) Migration is the main factor affecting the spatial heterogeneity of population aging. Per capital GDP and road network density are the second most influential factors. By contrast, the relief degree of land surface and the air quality index minimally influence population aging. The mechanisms of aging in various regions are affected by varying development levels. (3) The interaction among social, economic, and environmental factors enhances their effects and, thus, interacting factors have a greater influence on population aging than any single factor. The findings of this study have significant implications for local inhabitants and policy makers to address the population aging challenge in achieving sustainability of society, economy, and environment. will become the highest-aged country in the world [3]. Under the background of social transformation and space reconstruction, the aging of China is becoming more and more complex. "Aging before getting rich" and "demographic dividend disappeared", the notion in population and economic development, has been a serious threat to social sustainable development.

Under such a circumstance, the aging issue has become a common and fundamental subject for local inhabitants, scholars, and governments all over the world. In the Yangtze River Delta in 2010, as an important economically developed area, the proportion of individuals who were over 60 years was 10.45%, which was significantly higher than the national average. Meanwhile, the Yangtze River Delta is a core area for rapid urbanization. In 2010, the region's gross domestic product (GDP) increased to 7.07 trillion RMB, accounting for 16.42% of the national total. It is not only an economically developed region but also an area where interaction occurs between nature and humans, which has resulted in various environmental and ecological problems and brought great challenges to regional sustainable development.

“…However, the health and social advantages enjoyed by the urban population in China are challenged by the various consequences of China's rapid urban development, including a massive and ageing urban population, environmental pollution, large-scale internal migration, lifestyle changes, and rising social inequality. 52,53 Healthcare systems in urban China are particularly strained by growing urban populations, 54,55 rapidly increasing prevalence of non-communicable diseases, 4 and rising health inequalities (with respect to disease burdens and life expectancy). 5,56 These trends represent cracks in the foundation of health and wellbeing in Chinese cities that need urgently to be addressed.…”

“…Many studies have pointed out that there is a significant positive correlation between BA and the proportion of vulnerable groups (e.g., elderly and low-income) in the older areas of the megacity [44,45]. We found identical results in this study area, where the correlation between the mean BA and the proportion of elderly people at the community level is 0.473** (p < 0.001), that is, there are more elderly people living in old communities with older housing.…”

Assessing the Heat Vulnerability of Different Local Climate Zones in the Old Areas of a Chinese Megacity

Frequent and extreme heat waves have strongly influenced the sustainable development of cities and resulted in a higher level of mortality in residents. Using the Local Climate Zone (LCZ) classification scheme, combined with the factors of land surface temperature (LST), building age (BA), and housing price (HP), and the normalized values of which represent heat exposure, sensitivity, and adaptability, respectively, this paper investigates a practical method for assessing the heat vulnerability of different LCZ classes in the old areas of a Chinese megacity, taking the Yuzhong district of Chongqing city as a case study. The results reveal that the distribution of LCZ classes in this study area exhibits a typical circle-layer distribution pattern from the city center to the suburbs. Heavy industry areas are the most vulnerable, with the highest exposure to heat waves, the oldest building age and the lowest housing price. Compact class areas (compact high-rise, compact mid-rise and compact low-rise) are usually more vulnerable than open class areas (open high-rise, open mid-rise, and open low-rise) and low-rise buildings are always more susceptible to heat waves than mid-rise and high-rise buildings. The methods and findings can help us to better understand the comprehensive and space-time action rules of heat vulnerability, thereby inspiring scientific and rational urban planning strategies to mitigate or adapt to urban heat weaves towards the sustainable development of cities and society.2 of 15 an extreme heat wave caused more than 70,000 deaths in Europe [13], and the extreme heat waves in the United States from 1999 to 2010 resulted in 7415 deaths, more than the total number of deaths from typhoons, floods, earthquakes and other disasters during the same period [14].Therefore, it is urgent to assess the vulnerability of areas subject to urban heat waves and provide corresponding mitigation or adaptation strategies based on it. This has become a hot topic in the study of healthy cities. Heat vulnerability refers to the degree of vulnerability or inability of urban residents to cope with the adverse effects of heat waves, and it is typically composed of three types of indicators: exposure, sensitivity and adaptability [15,16]. In this context, "exposure" refers to the proximity of the location of a group or individual to the hazards of heat waves, which reflect the characteristics, intensity and frequency of the heat waves suffered by urban residents [17]. The most widely used indicators for evaluating heat exposure include the urban thermal environment (e.g., air temperature, land surface temperature and urban heat island intensity) [18,19] and urban spatial parameters (e.g., sky view factor and impervious surface fraction) [20]. In this context, "sensitivity" refers to the degree to which urban residents change their physiological structure in the face of the external interference of extreme heat waves. Widely used evaluation indicators include the proportion of vulnerable groups, such as the elderly, infants ...
