基于共词分析的我国资源环境领域研究热点分析

了解我国资源环境领域的研究热点及走向,可为该领域的论文选题、科研立项和学科规划提供参考信息和决策依据。本文采用共词分析法,Excel、SPSS等软件,对CNKI数据库中的相关文献进行统计。通过分析得出高频关键词并建立共词矩阵,进一步对高频词共词矩阵进行聚类分析和战略坐标图分析,得出资源环境领域的研究热点主要集中在人口资源环境与经济可持续发展、城市化与中国资源环境/水资源环境协调发展、资源环境约束或人地关系视角下的产业结构优化和城镇化发展、资源环境承载力评价指标体系与问题对策、经济增长与生态足迹关系、生态文明视角下的资源环境保护与管理等几大主题上。其中,前两个主题处于整个领域的核心地位,得到较深入的研究,后四个主题研究不够深入,仍有许多值得研究的地方。

Study on the Research Hotspot in the Field of Resource and Environment in China Based on Co-word Analysis

This study aims to understand the research hotspot and trend in the field of resource and environment in China, and provide the reference and decision basis for thesis topic selection, scientific research project, and disciplinary planning. The relevant literatures in CNKI database were analyzed using Excel, SPSS based on co-word analysis. The high-frequency keywords were obtained and the co-word matrix was established. Then through clustering and strategy coordinate diagram, the research hotspots in the field of resource and environment were found to focus on six major themes, including the sustainable development of population, resources, environment and economy, the coordinated development of urbanization and China resource environment/water resource environment, the industrial structure optimization and urbanization based on resource and environmental constraint and man-land relationship, the valuation index system and countermeasure of resource and environment carrying capacity, the relationship between economic growth and ecological footprint, and the resource environment protection and management from the perspective of ecological civilization. Among these six themes, the first two themes are in the core position, and were studied intensively. And the studies on later four themes were not deep enough, and there is a great development prospect.
