为深刻理解边坡演化与现代系统科学之间的关系,应用现代系统科学理论,对西安金盆水库高陡边坡的特征进行分析,指出该边坡与外界环境的不断交换体现了系统的开放交换原则;降雨强度由微涨落放大为巨涨落体现了系统的涨落放大原则;不同滑面形成优势面的过程体现了系统的竞争协同原则;边坡岩体的前期蠕变与后期水力条件改变触发的坡体急剧破坏体现了系统的渐变突变原则.同时,总结出边坡演化与现代系统原则的关系：即开放交换是边坡系统演化的条件;涨落放大是边坡系统演化的触因;竞争协同是边坡系统演化的驱动;渐变突变是边坡系统演化的途径.

英文摘要：

Modern system science was used to analyze the characteristics of highsteep slope of Jinpen reservoir in Xi＇an to deeply understand the relationship between slope system and modern system science.Results indicate that constant exchange between the slope and external environment reflects the open and exchange principle of system science,and the rainfall intensity changing from micro-fluctuation to macro-fluctuation reflects fluctuation and amplification principle of system science, and the process of specific slip surface developing to be dominant surface reflects synergic competition principle of system science,and rock creep and rapid destruction of slope triggered by hydraulic conditions reflect the gradual and sudden change principle of system science.At the same time,the relationship between slope system and modern system science is summarized,that is,open and exchange principle is the condition of slope evolution,and fluctuation and amplification principle is the inducement of slope evolution,and synergic competition principle is driving of slope evolution,and gradual and sudden change principle is the approach of slope evolution.
