摘要:

土地资源的生态安全问题日益突出, 土地资源生态安全研究成为当前土地资源可持续利 用研究的前沿课题。文章诠释了土地资源生态安全的概念, 并且对当前土地资源生态安全研究的 主要研究内容及研究进展进行了综述, 提出了将土地资源生态安全机理研究、土地资源生态安全 评价和土地资源生态安全设计研究整合起来进行综合研究的体系框架, 即在系统分析土地资源 生态安全影响机理的基础上, 构建土地资源生态安全评价指标体系, 进行土地资源生态安全评 价, 识别生态危机和生态安全的土地利用模式, 设计生态安全条件下的土地利用结构优化方案和 土地利用安全格局, 这种整合研究将成为区域土地资源可持续利用研究的趋势。其中土地资源生 态安全评价指标体系的构建、生态安全标准的判定以及土地资源生态安全格局构建仍是非常具 有探索性的工作, 也是未来土地资源生态安全研究的主要研究方向。

Abstract:

Ecological security is critical to sustainable development of human society, which includes resource security, biological security, environmental security and etc. And land resource ecological security is an important aspect of resources security. However, the ecological problems of land resource are increasingly serious in such terms as soil erosion, land pollution and desertification, which are threatening regional eco- security and sustainable development. Therefore, the research of land resource ecological security has become the forefront topic in the field of sustainable utilization of land resource. This article interpreted the concept of land resource ecological security firstly, and then summarized the main progress and achievements in land ecological security research, which include the relationship between land resource ecological security and land use/land cover changes, assessment of land resource eco- security and design of land resource eco- security. Finally this article put forward that special attention should be paid to following aspects in the future study of land resource eco- security. Firstly, there is an tendency to integration of the research on mechanism of land resource eco- security, land ecological security assessment and land resource eco- security design. Secondly, study of land eco- security assessment method as well as determination of the threshold of land resource eco- security index should be further discussed. And finally, construction of land use security pattern is still an exploratory work.

Key words: ecological security, land resource, sustainable development
