摘要

随着全球生态问题的日益突出,生态安全格局(ESP)的构建对于保障区域生态安全、协调社会经济发展、改善民生福祉显得尤为重要。基于源-阻力面-廊道-节点信息的生态安全格局构建已成为主要的研究范式。本研究采用文献分析法,从概念内涵、构建方法、评价与规范等方面系统地获取了ESP的相关研究成果。研究结论如下(1)随着时间的推移,动态格局构建已成为研究热点;从空间上看,对多尺度、跨行政边界的领域关注较少。(2)ESP 构建方法相对成熟,但仍存在一些不足,如忽视小尺度但重要的生态源、对物种生活习性考虑不足、缺乏廊道异质性研究、实地调查与考察不够等。(3)ESP定性评价侧重于分析生态源划定的合理性和准确性。相比之下,定量ESP评价侧重于生态网络(EN)的连通性、可达性和稳健性,应用更为广泛。多层次监管可促进 ESP 的实施。未来的研究重点应放在:(1)因地制宜选择生态系统服务,考虑权衡和协同关系;(2)深化生态系统服务时空演化研究,精确构建生态网络;(3)引入机器学习,实现智能化的生态系统服务系统构建。本文为今后的研究指明了方向,为系统、严谨地构建ESP勾勒了新思路,推动全球生态文明建设更加深入和务实。

Research progress and prospects for constructing ecological security pattern based on ecological network

Research progress and prospects for constructing ecological security pattern based on ecological network
As global ecological problems become increasingly prominent, the construction of ecological security pattern (ESP) has become particularly important for ensuring regional ecological security, coordinating social and economic development, and improving the livelihood and well-being of people. ESP construction based on source-resistance surface-corridor-node information has become the main research paradigm. In this study, the literature analysis method is employed to obtain relevant ESP research results systematically from the perspectives of conceptual connotations, construction methods, evaluations and regulations. The conclusions are as follows: (1) Over time, dynamic pattern construction has become a research hotspot; spatially, less attention has been given to areas with multi-scale and cross-administrative boundary. (2) The ESP construction method is relatively mature, but shortcomings remain, such as the neglect of small-scale but important ecological sources, insufficient consideration of species living habits, lack of research on corridor heterogeneity, and inadequate field surveys and visits. (3) Qualitative ESP evaluation focuses on analyzing the rationality and accuracy of the delineated ecological sources. In contrast, quantitative ESP evaluation focuses on the connectivity, accessibility and robustness of ecological network (EN), which has been more widely applied. Multilevel regulation can promote the implementation of ESP. Future research should focus on (1) selecting ecosystem services on the basis of local conditions and considering trade-offs and synergistic relationships, (2) deepening research on the spatiotemporal evolution of ecosystem services and accurate construction of EN, and (3) introducing machine learning to achieve intelligent ESP construction. This paper provides directions for future research, outlines new ideas for the systematic and rigorous construction of ESP and promotes more in-depth and practical global ecological civilization construction.

期刊介绍: The ultimate aim of Ecological Indicators is to integrate the monitoring and assessment of ecological and environmental indicators with management practices. The journal provides a forum for the discussion of the applied scientific development and review of traditional indicator approaches as well as for theoretical, modelling and quantitative applications such as index development. Research into the following areas will be published. • All aspects of ecological and environmental indicators and indices. • New indicators, and new approaches and methods for indicator development, testing and use. • Development and modelling of indices, e.g. application of indicator suites across multiple scales and resources. • Analysis and research of resource, system- and scale-specific indicators. • Methods for integration of social and other valuation metrics for the production of scientifically rigorous and politically-relevant assessments using indicator-based monitoring and assessment programs. • How research indicators can be transformed into direct application for management purposes. • Broader assessment objectives and methods, e.g. biodiversity, biological integrity, and sustainability, through the use of indicators. • Resource-specific indicators such as landscape, agroecosystems, forests, wetlands, etc.
