A bibliometric analysis of the research on Sponge City: Current situation and future development direction

Abstract

With the rapid development of urbanization, more and more cities are facing the risk of flood disasters and the threat of water environment safety during the rainy season. Sponge City, as a new urban water resources management method, has attracted extensive attention in the academic circle. In order to promote the development of Sponge City, a bibliometric analysis method based on Web of Science (WoS) database and Bibliometrix tool is proposed in this study. After refining the retrieved 26,383 papers, 1456 papers were obtained. All the article information including author, keywords and publication time was downloaded. The bibliometric analysis model was established to analyse and discuss the development of Sponge City and related researches during the period 1998-020 (data up to 15 August 2020). Research performance, research focus and development trend were displayed by bibliometric measurement indicators and visual graphics. The results show that the number of research papers on Sponge City has been increased year by year in the past 10 years (2010-2020). Sponge City and related research are increasing rapidly, and the top five countries in terms of research volume are China, the United States, the United Kingdom, South Korea and Canada. China, the United States, the United Kingdom and Australia are the countries with the most extensive international cooperation in the field of Sponge City. Keywords such as 'Sponge City', 'LID (Low Impact Development)' and 'SWMM (Storm Water Management Model)' appeared frequently. In our opinions, interdisciplinary research methods, digital information management technology and comprehensive performance evaluation are the hot research directions for Sponge City in the future. This study aims to provide directions for future research on Sponge City, as well as scientific guidance and reference for government decision makers on Sponge City.

Influences of Climate Change and Human Activities on NDVI Changes in China

“…Monitoring vegetation changes and their driving factors has become a hot and difficult topic in current research [6][7][8]. Since the beginning of the 21st century, rapid development of remote sensing technology [9] has allowed it to be used in many fields such as meteorological monitoring, soil reproduction, and urban research [10,11]. In addition, remote sensing images are widely used to monitor changes in vegetation coverage [12][13][14].…”

Flood Disaster Monitoring and Emergency Assessment Based on Multi-Source Remote Sensing Observations

“…From 1950 to 2017, flood disasters of different degrees occurred almost every year [1,2]. Among them, the strong El Nino phenomenon caused frequent and serious flood disasters in 2016 in most areas of China [3,4]. According to the 2018 China flood and drought disasters bulletin, nationwide, flood disasters were generally light but in some areas heavy.…”

Evaluation on the Change Characteristics of Ecosystem Service Function in the Northern Xinjiang Based on Land Use Change

“…Land use/cover change (LUCC), which describes the interaction between the human/land relationship and the ecosystem, is an important driving force that affects the transformation of ecosystem structure and function [3]. Therefore, closely linking LUCC with human well-being is of great significance for ensuring regional ecological security and socio-economic development [4][5][6]. In recent years, many Domestic scholars and abroad have conducted a lot of research on the value theory, type classification and accounting methods of ecosystem services, and have achieved rich results [7][8][9][10][11].…”
