    As an important foundation for promoting social progress and economic development, natural resources play an important role in the sustainable development of cities. However, the increasing demand of human beings for natural resources has led to various ecological environmental problems, such as excessive population density, serious environmental pollution, the continuous decline of total natural resources and per capita resources, all of which have hindered sustainable development. Therefore, the study of natural resources and sustainable development has become the focus of many current scholars. In this paper, CiteSpace is used as an analysis tool to analyze the literature on natural resources and sustainable development over the past 20 years. First of all, this paper deeply analyzes the research status of this field in terms of academic research trends, authors and research institutions, co-occurrence of keywords, etc., and on this basis, it then deeply analyzes its evolutionary path and research hot spots in the past 20 years through keyword emergence. Finally, according to the visualization of the analysis results, the future development trends of this research field are speculated: (1) Grasp the current research focus; (2) Improve the research accuracy; (3) Enrich the theoretical system of research; and (4) Establish an interdisciplinary research system.

    Journal of Resources and Ecology    2021, 12 (3): 430-436.   DOI: 10.5814/j.issn.1674-764x.2021.03.012

    To encourage the environmental responsibility of consumers and manufacturers for forest management, it is necessary to evaluate the environmental influences of forest products. Ecological footprint (EF) is an internationally recognized indicator for estimating the natural capital consumption and environmental influences of various forest products. In this study, we developed an accounting model for the EF evaluation of wood flooring, which is a tertiary forest product, by the method of transformation. Next, we used that model to evaluate the EF of three types of wood flooring in China according to their production data from 2000 to 2018. We collected the necessary data by visiting typical enterprises in China and referring to the relevant literature. According to our results, the average EFs of solid wood flooring, engineered solid wood flooring and laminate flooring between 2000 to 2018 were 3.13×10 6, 1.05×10 7 and 5.07×10 6gha, respectively. The total EFs of solid wood flooring, engineered solid wood flooring and laminate flooring from 2000 to 2018 were 5.95×10 7, 1.99×10 8and 9.64×10 7gha, respectively. The coefficients of variation (CV) of the EFs for these three types of wood flooring were 0.45, 0.87 and 0.76, respectively. The average and total EFs of the engineered solid wood flooring were the largest among the three types of wood flooring. The per capita EF and unit EF for the engineered solid wood flooring were also the highest among the three types of wood flooring. The EFs showed an upward trend with irregular fluctuations from 2000 to 2018 for all three types of wood flooring. It is necessary to reduce the EF of the engineered solid wood flooring and use more environmentally friendly products, such as solid wood flooring, for environmental protection.
