Conceptual Planning of Urban–Rural Green Space from a Multidimensional Perspective: A Case Study of Zhengzhou, China

Abstract

The structure and function of green-space system is an eternal subject of landscape architecture, especially due to limited land and a need for the coordinated development of PLEs (production, living, and ecological spaces). To make planning more scientific, this paper explored green-space structure planning via multidimensional perspectives and methods using a case study of Zhengzhou. The paper applies theories (from landscape architecture and landscape ecology) and technologies (like remote sensing, GIS—geographic information system, graph theory, and aerography) from different disciplines to analyze current green-space structure and relevant physical factors to identify and exemplify different green-space planning strategies. Overall, our analysis reveals that multiple green-space structures should be considered together and that planners and designers should have multidisciplinary knowledge. For specific strategies, the analysis finds (i) that green complexes enhance various public spaces and guide comprehensive development of urban spaces; (ii) that green ecological corridors play a critical role in regional ecological stability through maintaining good connectivity and high node degree (Dg) and betweenness centrality index (BC) green spaces; (iii) that greenway networks can integrate all landscape resources to provide more secured spaces for animals and beautiful public spaces for humans; (iv) that blue-green ecological networks can help rainwater and urban flooding disaster management; and (v) that green ventilation corridors provide air cleaning and urban cooling benefits, which can help ensure healthy and comfortable urban–rural environments. In our view, this integrated framework for planning and design green-space structure helps make the process scientific and relevant for guiding future regional green-space structure.

Problems and Countermeasures of China’s Greenway Economic Development from the Perspective of Computer Internet

“…Figure 3 shows the Internet technologies used in greenway planning and greenway approaches. It is possible to identify and demonstrate UGC planning techniques by analyzing the recent UGC structure and relating physical aspects to theories on “landscape architecture and ecology” as well as technologies like geographic information system (GIS), remote sensing, and graph theory [ 34 ].…”

Exploring the raison d’etre behind metric selection in network analysis: a systematic review

“…Arora and Ventresca (2018) use Betweenness and Closeness centrality for preferential linking in the synthesis of resilient Supply Chain Networks (SCN), where centrality measures act as proxies for price, performance and quality. Mu et al (2020) examine the spatial distribution of green space and physical factors to explore alternative green space planning strategies using Degree, Closeness and Betweenness. Garrett et al (2017) adopt Degree, Closeness, Betweenness, Eigenvector as measures of centrality to explore food security and agricultural networks (alongside Cliques, Diameter and Path Length).…”

Graphab: An application for modeling and managing ecological habitat networks

“…Most of these planning approaches were based on spatial simulations of urban development scenarios, either for comparing the potential impacts of several urban forms [55][56][57] or for planning actions to mitigate urban expansion [58]. Other urban planning studies using Graphab have been conducted to evaluate the biological potential of green spaces [42,59] or to assess their permeability as stepping stones [60,61]. Graphab has also been used as a tool to include stakeholders in connectivity analysis [62,63], to initiate public debate in the context of an action against an infrastructure project [62] and to explore the covariations between visual and ecological landscape qualities [64].…”
