摘 要:土地资源安全是资源安全的重要组成部分,是土地可持续利用的延续。随着人类活动的加剧以及气候变化的影响,我国的土地资源安全问题面临着极其严峻的形势。基于此,本文从土地资源安全的内涵、现存问题、影响因素及土地资源安全研究进展、技术方法、发展趋势以及土地资源安全保障等方面展开和阐述,得出借助多科学和技术,采用合适方法、体系,尤其考虑气候变化相互作用机制等因素,对土地资源安全评价、预测并保障是未来发展趋势的启示。本研究旨在加深对土地资源安全的理解并为今后对其深入的研究提供方向和建议。Land resource security is an important component of resource security and is a continuation of sustainable utilization of land resource. With intensification of human activities and increasing effect of climate change, the security of land resource in China has been facing a very serious situation. Based on this background, this paper illustrated deep meaning problems and impact factors of the land resource security, research development, methodologies, development tendency of assessment of land resources security and security strategies of land resources security firstly. And then, it revealed that it was tends to evaluate and predict the land resource security in future by adopting appropriate methods and assessment systems based on multi-discipline, technologies, especially taking into account of the interaction of cli-mate change. In all, this overview was aimed to make a much more profound understanding to the land resources secu-rity and to provide some referenced suggestions for further research and decision-makers.
