Examining urban land-cover characteristics and ecological regulation during the construction of Xiong'an New District, Hebei Province, China

Development of Xiong'an New District(XND) is integral to the implementation of the Beijing-Tianjin-Hebei(BTH) Integration Initiative. It is intended to ease the non-capital functions of Beijing, optimize regional spatial patterns, and enhance ecosystem services and living environment in this urban agglomeration. Applying multi-stage remote sensing(RS) images, land use/cover change(LUCC) data, ecosystem services assessment data, and high-precision urban land-cover information, we reveal the regional land-cover characteristics of this new district as well as across the planned area of the entire BTH urban agglomeration. Corresponding ecological protection and management strategies are also proposed. Results indicated that built-up areas were rapidly expanding, leading to a continuous impervious surface at high density. Urban and impervious surface areas(ISAs) grew at rates 1.27 and 1.43 times higher than that in the 2000 s, respectively, seriously affecting about 15% area of the sub-basins. Construction of XND mainly encompasses Xiongxian, Rongcheng, and Anxin counties, areas which predominantly comprise farmland, townships and rural settlements, water, and wetland ecosystems. The development and construction of XND should ease the non-capital functions of Beijing, as well as moderately control population and industrial growth. Thus, this development should be included within the national ‘sponge city' construction pilot area in early planning stages, and reference should be made to international low-impact development modes in order to strengthen urban green infrastructural construction. Early stage planning based on the existing characteristics of the underlying surface should consider the construction of green ecological patches and ecological corridors between XND and the cities of Baoding, Beijing, and Tianjin. The proportion of impervious surfaces should not exceed 60%, while that of the core area should not exceed 70%. The development of XND needs to initiate the concept of ‘planning a city according to water resource amount' and incorporate rainwater collection and recycling.

Events as a means to foster knowledge-driven urban development:Experience from the new district development in Nanjing

Events can bring important impetus to urban development.In addition to hardware investments,such as infrastructure,events also have important potential in the development of knowledge cities.Nanjing is a typical city where China’s knowledge industry is rapidly growing.Since the end of the last century,Nanjing has been promoting new district development on the city’s periphery and has hosted a series of events,including the 10th National Games in 2005 and the 2nd Youth Olympic Games in 2014.In this process,the city government also hopes to explore the potential of the knowledge economy and is committed to providing a new direction for urban development.This work reviews the history of Nanjing’s knowledge city development from two different dimensions(land development and knowledge development)and summarises the related achievements and lessons in different periods.The authors aim to identify the diverse effects of events in urban social and economic development based on the analysis of the differences in governance structure between land development and knowledge development.This work contributes to the literature on events and provides insights into the potential uses of events as a mechanism for knowledge-driven urban development.
