Abstract: Fragile ecological environment is an unstable factor influencing the live supporting environment in bad ways. Taking Horqin Sandy Land as an example, this paper discusses a series of disturbance factors making impacts on landscape unstability and changes, including ecology of individuals, population ecology, ecological niche, community ecology, and ecosystem. The substance of disturbance is transmission of energy flow, matter flow, and information flow. This paper analyses the possibility to set up landscape ecology model by different ecological disturbance factors.

Key words: Fragile ecological environment, Landscape disturbance, Response analysis
