The Focus and Frontier of Green Infrastructure Research Based on CiteSpace Bibliometrics Analysis

Abstract

Green infrastructure (GI) has been paid more and more attention by scholars as an effective measure to solve problems of environmental degradation and biodiversity destruction, and improve living environment. In this paper, we carried out visualized analysis of related research on GI using CiteSpace software. Some 947 GI-related English literatures from Web of Science database and 400 Chinese literatures from CNKI database were sampled, and analyses were performed on academic institutions cooperation network, keywords co-occurrence, literature co-citation. It is found that there is still a large gap in GI research between China and abroad. Through summarizing the progress and characteristics of internaional GI research, we put forward four suggestions for GI research in our country: ① strengthen cooperation between academic institutions; ② strengthen interdisciplinary cooperation and expand research areas; ③ the research focus should be extended to quantitative, comprehensive performance evaluation, and establishment of scientific management mechanism; ④ propose areas that should be paid more attention to and explored in the future. In the face of increasingly serious environmental and ecological problems in the world and China, green infrastructure will surely become the focus of future development.
