基于文献计量的中国土地生态安全评价研究进展

Quantitative Analysis on Literature of Evaluation on Land Ecological Security in China

运用文献资料法、网络检索法和对比分析法,对中国土地生态安全评价研究文献的主要研究内容、特点与研究趋势进行了归纳总结。结果表明:(1)2006年后,土地生态安全评价问题受到广泛关注。(2)主要研究区域为湖南、重庆、陕西和湖北;研究群体以从事土地科学、生态学等方面的理论工作者为主,核心作者群尚未形成。(3)文献离散状况分析表明,期刊的核心效应较明显,学术水平总体较高。(4)我国土地生态安全评价主要有自然—经济—社会模型和压力—状态—响应模型两种指标体系;综合指数法最常用,占比为52.40%,其次是物元分析法和土地承载力分析法。

The purpose of this study was to summarize the basic features, main contents and characteristic of the papers. Methods of document- ation, network retrieval and comparison were employed. The results showed that：①Evaluation on land ecological security was concerned closely since 2006 .②The hotspots of evaluation on land ecological security research were Hunan, Chongqing, Shanxi, Hubei, and the main researchers were from universities, and the core author group hadn＇t formed. ③Disereteness of literatures gave strong evidence of core effect. ④The index system of evalu- ation on land ecological security mainly include nature - economy- society model and pressure - state- response model, and the comprehensive index method, the matter- element analysis and land bearing capacity analysis were always used.
