| 摘 要： | 脆弱生态环境是影响生存环境，导致环境日趋恶化的不稳定因素。本文以科尔沁沙地为例，从景观和景观生态出发，论述影响脆弱生态环境景观不稳定性的各生态等级尺度的扰动因子，即个体生态、种群生态、生态位、群落生态、生态系统。同时文章认为各种干扰的实质是能流、物流、信息流的传递，分析各生态等级尺度扰动因子有助于建立景观生态模型，从而更好地研究脆弱生态环境及其景观扰动。

| 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. |
