RESPONSE ANALYSIS OF DIFFERENT ECOLOGICAL LEVEL FACTORS TO LANDSCAPE DISTURBANCE IN FRAGILE ECOLOGY ENVIRONMENT FROM HORQIN SANDY LAND
从科尔沁沙地分析不同生态水平因子对脆弱生态环境景观扰动的响应

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.
