Although urban fringe is regarded as a unified academic concept, the actual development results present a strong divergence into two categories: the strongsided urban fringe and the weak-sided urban fringe. This paper starts from basic concept of the weak-sided urban fringe based on existing theory and summarizes the features of the weak-sided urban fringe according to empirical cases, including the low-quality, collage-style land use mode, the structural shortage of both core resources and fundamental facilities, and the fragmented spatial governance. Secondly, differing from the development of strong-sided urban fringe with high investment, urban sprawl and self-replication dominated by growth machines during the rapid urbanization period, this paper proposes the weak-sided urban fringe should adopt a flexible planning approach characterized by precise input, structural optimization and organic growth. Finally, taking the example of Strategic Plan of Yuhuatai District，this paper initially discusses the methodology of flexible planning, including repair of embedded structures, action-oriented organic regeneration and the organizational optimization of multi-governance systems guided by planning.

The Impact

The environment of the urban fringe is complex and frangible. With the acceleration of industrialization and urbanization, the urban fringe has become the primary space for urban expansion, and the intense human activities create a high risk of potentially toxic element (PTE) pollution in the soil. In this study, 138 surface soil samples were collected from a region undergoing rapid urbanization and construction—Weinan, China. Concentrations of As, Pb, Cr, Cu, and Ni (Inductively Coupled Plasma Mass Spectrometry, ICP-MS) and Hg (Atomic Fluorescence Spectrometry, AFS) were measured. The Kriging interpolation method was used to create a visualization of the spatial distribution characteristics and to analyze the pollution sources of PTEs in the soil. The pollution status of PTEs in the soil was evaluated using the national environmental quality standards for soils in different types of land use. The results show that the content range of As fluctuated a small amount and the coefficient of variation is small and mainly comes from natural soil formation. The content of Cr, Cu, and Ni around the automobile repair factory, the prefabrication factory, and the building material factory increased due to the deposition of wear particles in the soil. A total of 13.99% of the land in the study area had Hg pollution, which was mainly distributed on category 1 development land and farmland. Chemical plants were the main pollution sources. The study area should strictly control the industrial pollution emissions, regulate the agricultural production, adjust the land use planning, and reduce the impact of pollution on human beings. Furthermore, we make targeted remediation suggestions for each specific land use type. These results are of theoretical significance, will be of practical value for the control of PTEs in soil, and will provide ecological environmental protection in the urban fringe throughout the urbanization process.

Key Issues

Rapid urbanization in the past four decades has transformed the hinterlands of China’s major cities. While urban growth has consumed large quantities of farmland, many of the remaining farms in the country’s peri-urban fringes have responded to the nearby presence of a fast-expanding and wealthier urban market by changing the farm enterprise to cater directly for this market. The various responses are exemplified herewith, for the metropolis of Xi’an-Xianyang (13 million population), in north-west China’s Shaanxi Province. Based on participant observation and structured interviews with a sample of farmers from three peri-urban fringe villages, the study charted changes in ecosystem services as a quantitative measure of change between 1986 and 2017. An additional Delphi approach focused on the chief technological innovations during this period. The survey revealed the growing multi-functionality of those villages that had switched from traditional grain production to horticulture, supported by various government-funded programs. A significant development has been the introduction of farm-based tourism catering for urban-based tourists. The physical appearance of the fringe now resembles the so-called desakota landscape associated with south-east Asian cities, as massive new urban-industrial complexes sit alongside villages amidst islands of intensive farmland. The conclusion addresses key issues regarding the overall sustainability of agriculture within this fast-changing process of rapid urbanization.

With rapid urbanization, villages on urban fringe are being merged with city, among which, ancient villages are of no exception. In this study, Jingangbei village in Beibei district, Chongqing city was selected as the object for investigated. Through field investigation and literatures retrieval, history, space form and cultural features of Jingangbei were illustrated. In addition, by comparing of the protective plan and current situation of Jingangbei, chances and challenges for ancient villages’ protection were put forward, namely: Administration of Cultural Relics and local residents’ participation; change of planning objectives from wealth-seeking to multidimensional objectives; sources of protect funding and definition of future functions.

Planning Approaches

Abstract Conventional planning approaches that prioritize built-up areas and rapid urbanization for economic growth and social security, instead of the environment and the ecological services they provide have consistently been problematic in maintaining sustainability. Because of this, there is a growing need to shift from the conventional to a greener approach. The research argues that an ecological management approach is a viable choice of approach in protecting the ecological integrity of the landscape, especially in biotopes where ecological services are sought-after, such as the karst system Susong Dalaga found in Cabarroguis, Quirino Province. This approach is done by identifying the different biotopes to find the existing relations, services, and underlying issues of the place. In assessing the items mentioned earlier, the research finds that the natural systems are slowly dwindling due to the expansion of agriculture and built-up areas. Each biotope is then assigned with an appropriate approach, and with the consultation of the stakeholders, policies are then strategized for specific functions. It is hoped that the study would help push the application and integration of ecological management approach, and green approaches and principles in general, to future urban planning projects in the Philippines.

Using Data

Rapid urbanization enhances the desirability of policies for preserving open space but policies intended to preserve open space may extend the urban boundary and create leapfrog development. We investigate this potential conflict between open space preservation and urban sprawl conceptually and empirically using data from the Baltimore-Washington suburbs. In accord with previous theoretical and empirical results, the estimated econometric model indicates that both zoning and forest planting requirements contribute to sprawl by increasing the amount of land needed to accommodate the current number of households. These results point to a conflict between preserving open space incorporated into private building lots or internal to subdivisions and public open space at the urban fringe.
