中国生态安全评价研究进展

Research progress of ecological security assessment in China

生态安全是可持续发展研究的新领域,是对生态系统整体安全状况的定量描述,对保护和发挥良好的生产与生态服务功能具有重要作用。在概述生态安全理论内涵的基础上,从评价尺度、评价模型与指标体系、评价方法、评价标准与评价结果分级等方面综述了国内生态安全评价研究进展,进而针对目前我国生态安全评价研究和应用中存在的一系列问题,提出加强生态安全的理论研究、完善评价模型与指标体系、制定科学合理的评价标准、实现不同尺度研究紧密结合、构建重点区域监测与预警平台、健全安全维护与管理调控系统等发展对策,以期为推进深入系统的生态安全评价研究提供依据。

Ecological security is the new research field of sustainable development, it is the quantitative description of security situation in the ecological system as a whole, it also plays an important role in protecting and providing good production and ecological service function. On the base of analyzing the conception and theory of ecological security, this paper summarized the research progress of domestic ecological security assessment including evaluation scale, assessment model, assessment indicator, assessment method, evaluation standard and the classification of assessment result. Finally, in order to provide reference for promoting systematic research of ecological security, this paper proposed the trends of ecological security research aimed at the problems existing in domestic research and application, such as strengthening the study of ecological security theory, consummating the evaluation model and index system, formulating scientific and reasonable evaluation standard, combining different evaluation scale researches closely, building monitoring and warning platform with important areas, improving the security maintenance and management regulation system.
