生态安全格局研究的主要内容与进展

生态安全格局是我国国土空间开发战略格局的重要组成部分。区域生态安全格局的有效构建及维护不仅有利于生态系统结构与功能的完整、生物多样性保护、生态系统服务的维持,还将提升人类福祉,实现可持续发展,最终保障区域生态安全。生态安全的复杂性及学科交叉性,使已有研究涉及内容多样,但缺少相互联系与比较,导致不同区域、不同方法研究条件下存在多种格局。因此,有必要系统地分析与梳理,以便进行综合分析与集成,实施生态安全格局调控管理与决策。参考国内外生态安全格局的主要研究成果,在此基础上阐述了生态安全格局研究需要重点关注的内容及之间的相互关系,在考虑"格局形成、演变机制-影响-关键区识别-构建优化-调控管理"的关系基础上,论述了具体的研究内容与相关研究方法。通过加强生态安全主要研究内容间相互关系及机理研究,评估与预警方法模型的改进与优化,协调发展的调控技术与保障政策的研发,为生态安全格局管理的决策支持系统提供重要支撑。

Main research contents and advances in the ecological security pattern

Ecological security pattern is an important part of China''s territorial development strategy. Effective construction and maintenance of a regional ecological security pattern not only contributes to the integrity of ecosystem structure and function, biodiversity conservation, and ecosystem services maintenance but also enhances human well-being, promotes sustainable development, and eventually improves regional ecological security. Owing to the complexity and interdisciplinary nature of ecological research, abundant content is generated by previous studies, but interconnections and comparisons, which may lead to identification of many patterns through different methods for different regions, are lacking. Therefore, systematically analyzing the studies is important to carry out a comprehensive integration, and inform management decisions for ecological security pattern. In this paper, we illustrate key subjects and relationships among previous studies of ecological security pattern, and discuss main research contents and methods in the contexts of pattern formation and evolution mechanism-pattern impact-key area identification-pattern construction and optimization-regulation and management logical relationship. Decision support system for ecological security pattern management can be improved by strengthening research on the mechanisms of key processes of ecological security, improving and optimizing the evaluation and forewarning methods, and developing ecological security regulation techniques and safeguarding policies.
