摘    要:基于对土地生态安全研究中自然、经济、社会子系统协同演变的机理分析,构建土地生态安全协同演变概念模型,并明确该模型定量测算方法。在不同情况下土地生态安全发展度可以分为安全、敏感、波动、危险和灾害等5个级别,而土地生态系统的协同演变轨迹会分为协同发展、可改善的发展、可改善的退化、完全退化等4种模式。实证分析表明:1996~2005年淮安市土地生态安全处于敏感级别,各子系统之间的协同作用有所增强,但如果维持现状不变,2006~2010年土地生态安全发展度与协同度将处于下降通道。

关 键 词:土地生态安全  演变  协同作用

Abstract:Based on the analysis of synergy evolution mechanism among land use natural system,economic system and social system in research of land ecological security,this paper conceived a concept model for this research and gave the calculation of this model.The development degree of land ecological security can be divided into five classes as security,sensitivity,fluctuation,danger and disaster under different circumstances and its synergy evolution track can be divided into four modes of synergy development,improvable development,improvable degeneration,complete degeneration.Taking Huai’an city as an example,the paper defined the land ecological security as sensitive degree during 1996-2005,and the synergy effect trends to be enhanced among three systems,however,its development degree and synergy degree will both be decreased during 2006-2010 if the circumstance tends to continue.
Keywords:land ecological security  evolution  synergy effect
