区域生态安全格局优化研究进展

区域生态安全格局的最优化是保障区域生态安全的基础,采用模型方法准确地对区域生态安全格局进行分析及优化对于区域生态环境可持续发展有重要意义。区域生态安全格局优化需要多学科的综合、多角度的分析和多种实现手段的结合。一般建立在对不同景观类型、景观的空间格局、景观过程以及功能之间关系深入理解的基础上,首先找到景观格局对过程的影响方式,建立数量关系,其次利用景观生态学的原理集成数学模型,优化土地利用,多层次、多角度、多学科进行区域生态安全格局优化。本文在分析国内外相关研究进展的基础上,对区域生态安全格局的概念发展、研究内容演变、优化方法等进行了总结,在此基础上得出未来区域生态安全格局优化的研究趋势:多模型、多方法、多技术的有机集成;区域生态安全标准量化的探索;公众参与机制及利益协调的管理手段研究。

Progress in Research on Regional Ecological Security Pattern Optimization

Optimization of regional ecological security pattern is the basis of regional ecological security. It is of great significance to analyze and optimize the regional ecological security pattern by using proper models and methods. The optimization of regional ecological security pattern requires the integration of multi-disciplinary synthesis, multi-perspective analysis and the combination of various means. It is generally based on the understanding of the relationship between different landscape types, landscape spatial pattern, landscape process and function. Typically, the impact ways of landscape pattern on the process are found first. Then, a mathematical model is built based on the principles of landscape ecology to optimize land use and local ecological security pattern from multi-level, multi-perspective and multi-disciplinary views. Based on the analysis of domestic and foreign research progress, a summary of the concept development, the evolution of the research content and the optimization methods of regional ecological security pattern was made. And the future research trend of regional ecological security pattern was obtained, including organic integration of multi model, multi method and multi technology, quantitative exploration of regional ecological security standards, public participation mechanism and management methods of interest coordination.
