基于共词聚类分析的国内外街旁绿地研究前沿比较及创新思考

街旁绿地相较城市公园分布更加广泛，是缓解高密度城区市民就近游憩需要的重要节点。十九大报告提出，要提供更多优质生态产品以满足人民日益增长的美好生态环境需要，街旁绿地建设日益迫切。基于共词聚类法对国外与国内近年来有关街旁绿地理论研究前沿议题分析表明，国外研究关注领域为公众健康、受伤防范、环境正义、空间生态系统服务；国内为景观特色、人性化设计、存量空间优化、空间生态性研究。通过对比两者在研究广度、深度、方法方面的差异，国内研究在认知、目标、方法、内容方面相较国外存在一定不足。参考国外研究的一般经验，并充分结合中国城市发展的总体要求，提出未来中国街旁绿地理论研究可从4个方面推进：一是推进空间分布的公平性及规划对策研究；二是加强围绕提升使用效果的空间研究；三是重视与加强对空间社会性与生态性的协同-交互关系研究；四是注重多学科思想的融入及综合方法应用。

Comparison and Innovative Thinking of Research Frontiers on Roadside Greenspace (RGS) at Home and Abroad: Based on Co-word Cluster Analysis

The roadside greenspace (RGS) is more widely distributed than urban parks, and it is an important node for alleviating the need for nearby recreation of high-density urban residents. The 19th National Congress of the Communist Party of China (NPC) reported that it is necessary to provide more high-quality ecological products to meet the people''s growing needs for a better ecological environment, and the building of RGS is increasingly urgent. As we analyze the research frontiers on RGS based on co-word analysis, among which the foreign research focuses on public health, injury prevention, environment justice and ecological system service of space, while the domestic research presents high focus on space landscape features, humanized design, inventory space optimization and spatial ecological research. By comparing foreign and domestic leading topics for discussion and typical writings, there have some differences in cognition, perspective, method and content between them, and theoretical research on China''s future RGS can be promoted in the following four aspects: the first is to promote the fairness of spatial distribution and the study of planning strategies in the new era; the second is to strengthen the research of improving the use of effects; the third is to strengthen the research on the coordination and interaction between spatial sociality and ecology; and the fourth is pay attention to the integration of multi-disciplinary ideas and the application of integrated methods.
