摘　　要：在剖析我国土地生态安全发展脉络的基础上,从概念、理论、研究尺度、指标体系与评价方法五个方面进行综述,阐明现有研究的主要规律、特点、不足及未来发展方向。结果表明:我国土地生态安全理论与方法的研究均表现出长足发展,但理论发展相对滞后;基于不同学科研究的侧重点有所差异,但目的具有高度的一致性;长期发展趋势变化主要体现在研究尺度、指标选取、评价方法及研究思路上。未来的研究可在理论的探讨与整合、评价指标权重与安全阀值的确定、研究对象的综合对比等方面进行深入研究,同时,应适时在土地资源安全整体框架下探讨土地生态安全问题,进行整体系统的评价。The purpose of this study is to analyze the development of land ecological security in China, review of five aspects including coneepts, theories, scales, index system and evaluation methods, clarify the main laws, characteristics, shortcomings of current researches and future development, provide methods and referenees for the evaluation and research of land ecological security in China in the future. The results showed that both theories and methods show considerable development, whereas methods run faster. The research purpose is the same even though they come from different disciplines. The long - term development trend is mainly reflected in the change of research scales, index selection, evaluation methods and research ideas. It is concluded that deeply study should be made in discussing and integrating of theories, determining the weights of evaluation indicators and safety critical values, contrasting synthetically between research objects, in addition, the problem of land ecological security under the overall framework of land resources security should be studied, and systematic evaluation be carried out.
