界面理论与生态脆弱带的生态安全分析

Interface Theory and Ecological Safety Analysis of Ecological Fragile Zone

生态脆弱带的生态安全问题是当今生态学研究的热点。将农业生态系统中的界面理论与景观生态学中的异质性过渡区域——生态脆弱带相结合,从界面理论、生态脆弱带、生态安全的基本概念出发,从基本特征和结构功能两方面分析了界面和生态脆弱带的相关性,归纳总结了国内外的研究进展,比较了地里边界法、遥感和地理信息系统方法及移动窗口法的优缺点,在此基础上对生态脆弱带的生态安全进行了展望。

The ecological security of ecological fragile zone is a hot issue in today＇s ecology study. The interface theory in agro-ecosystem was combined with the ecological fragile zone,which was a hetero-transition region in landscape ecology. Starting from the basic concept of interface theory, ecological fragile zone, ecological security, the correlation between the interface and ecological fragile zone was analyzed from two aspects of the basic characteristics and structural features. The study progresses at home and abroad were summarized. The advantages and disadvantages of the study methods, such as geographic boundary method, RS and GIS method and moving split-window method were compared. Based on this, the ecological safetT in ecological fragile zone was predicted.
