中国土地生态安全研究进展

剖析土地生态安全的概念内涵及其3大类别;从人地关系、可持续发展和相关学科基础3方面总结了土地生态安全研究的基础理论;从土地生态系统安全性和土地生态服务价值、评价、土地生态规划与设计和土地生态安全变化的驱动力4方面进行评述。从而指出,由于基础理论研究不足、缺乏动态评价和研究框架及其监测、预警和决策支撑体系以及研究区域和对象狭窄等原因限制中国土地生态安全广度和深度的研究;同时提出了今后应加强学科理论研究及其框架体系构建、建立区域土地生态安全评价、监测、预警和决策体系和加强土地生态管理等方面的措施,以期对未来发展趋势提出展望。

Research Progress of Land Ecological Security in China

This paper firstly analyzes the connotation of land ecological security and its three categories. Secondly, it summarizes the basic theory about it, which includes man-Iand relationship theory, sustainable development theory and basic theory of relevant discipline. Thirdly, it reviews the research progress on the four aspects of land ecosystem security and land ecological service value, land ecology assessment, land ecological planning and design and driving forces of land ecological security change. It is pointed out that the study of land ecological security is greatly limited in breadth and depth due to the deficient research on basic theory, dynamic assessment, research framework, the system of monitoring, early-warning and decision-support and the narrowness of researching region and object. To solve the above problems, some measures are proposed including strengthening the study on land ecological discipline, building the framework system for land ecological security, establishing the system of monitoring, early-warning and decision-support for regional land ecological security and strengthening the management for land ecology. Finally, the future developing trend about land ecological security is prospected.
