摘　　要：首先解释景观生态安全及“景观污染”的涵义,指出景观生态安全具备三位一体的特征,运用生态学、景观学、建筑物理学等相关理论对影响景观安全的环境要素作了进一步分析,并通过对景观环境的生态承载力,景观生态安全度,景观生态能量级等相关理论概念的阐述,提出城市景观生态系统的评价模式框架,指出景观生态系统的复杂性,决定了其评价的复合性和动态性,具有动力学的效应及机制,管理调控应根据系统运行的特征制定相应的调控原则及措施,城市景观生态的安全与健康应与城市生态系统的安全体系研究同步进行,对解决目前景观规划设计中存在的许多问题提供理论参考.By analyzing the meaning of city landscape ecology security and the landscape pollution, the paper puts forward the ＂three in one＂feature of the city landscape ecology security, and applies relevant theories such as ecology, landscape, and building physics to a further study of its effect factors. Further more, through analyzing the theory of the carrying capacity of landscape ecology, landscape ecology safety degree, energy grade of landscape ecology, it points out the evaluating model for the city landscape ecological system. The paper also points out that the landscape ecology system is very complicated and its evaluation is complicated and moving. The control measures should be drawn up by the system features, a theoretic reference for settling problems of landscape planning and design.
