摘 要 ：土地生态安全格局研究不仅可以为有效解决水土流失、土壤退化等区域生态安全问题提供新的思路，而且对提高区域土地生态系统的安全性和可持续性具有重要的现实意义。从土地利用生态安全评价、面向生态的土地利用格局和土地生态安全格局构建方法3个方面,综述了土地利用生态安全格局的研究现状和最新进展，并对今后的研究方向进行了展望，以促进土地生态安全格局研究的继续深入开展。提出近期的研究重点主要包括:（1）面向生态安全格局设计的生态安全评价方法与模型；（2）不同类型生态脆弱地区的土地生态安全格局；（3）土地生态安全格局的空间显示模型；（4）区域土地生态安全格局情景模拟。

Abstract:The research of Land ecological security pattern not only can provide a new thinking of effectively solving regional ecological security problems including soil and water loss, soil degradation, desertification, but also has an important realistic meanings for improving the safety and sustainability of land use ecosystem. In this paper, the present research status and some recent advances in the land use ecological security assessment, land use pattern based on ecology, optimization method of land ecological pattern are reviewed, and future research directions are discussed. In the near term, the priority research areas are:（1）Method and model of ecological security assessment for ecological security pattern; （2）Land ecological security pattern of different ecological friable areas; (3) Spatial explicit model of land ecological security pattern; (4) Scenario simulation of regional land ecological pattern.
