摘　　要：从斜坡岩体的结构组成、运动特征、岩石力学试验、统计物理学特征及分形几何学等方面研究了斜坡系统的复杂性特征。提出了斜坡系统是开放的复杂系统的新认识，指出滑坡预测同时应重视确定性知识与非确定性知识的综合运用，且应立足于基于满意原则的预测思想。应以预测过程和结论的“满意解”为原则，不必花费高代价去追求“最优解”。The complexity features of slope rock mass are studied by their structural components, their dynamic charaeteristics, rock mechanics tests and statistical physies analysis, as well as fractal geometry features. Based on the study, some new thought is put forward. As the slope system is an open and complex one, the best way of the prognosis for such a system should be the synthetic method to well combine the certainty and uncertainty methods. At the same time, it is emphasized that the prediction of landslides should be initially based on the satisfactory principle. This means that we should aim at satisfactory solution of the complex slope system rather than the optimum solution with high cost.
