摘要
以相关数据库收录的论文、科技成果和资助课题为基础,利用文献计量方法对土地资源学领域涉及的主题、论文发表年代、期刊种类等进行了统计分析。结果表明:国家自然科学基金资助的项目、中国学位论文、期刊论文在土地资源方面主要集中在资源评价和土地利用/土地覆被变化这2个主题;土地资源学方面的论文、成果的数量连年持续增加,表明土地正成为社会关注的焦点;从土地资源领域论文期刊分布来看,影响因子较高的学报级期刊比例较小,地区性学术期刊论文较多,说明土地科学研究的理论水平亟待提高;土地资源领域科技成果以应用研究和工作项目成果为主,注重解决土地资源调查、监测、评价中的实际问题,科技成果注重向实用性和应用性方向发展。综合以上分析,进一步对今后土地资源学各研究主题的发展趋势进行了展望,提出未来土地资源学研究的重点和发展方向。
Based on some research paper and achievement databases, this paper makes statistical analysis on selected topic distribution, chronological distribution and periodical distribution. It is found that evaluation of land resources, land use and land cover change have been becoming the focus of those project supported by National Natural Science Foundation of China, Chinese degree papers and periodical papers. With much regard to land issues, the number of periodical papers and research achievements concentrated on land resource research increased gradually, it showed that land is becoming the focus of social attention. In view of periodical distribution, the proportion of periodical papers which belong to transaction level is very low, so land resource research should be improved. Furthermore, scientific research achievements pay more attention to practicability and application. As a result, the research emphases and directions of different topics in the future were put forward in this paper.
