| 摘 要： | 水土流失,其实是一种主要的侵蚀地貌演化过程。本文以戴维斯提出的地貌侵蚀循环学说为基础,把高程-面积分析法运用到流域地貌发育研究之中,把济南山丘区地貌发育阶段分为壮年期和老年期。各流域土壤侵蚀危险度平均值、土壤侵蚀强度综合指数的大小次序与其地貌发育阶段呈现良好的对应关系,说明尽管人类活动是加剧土壤侵蚀的主要原因,但地貌发育过程对土壤侵蚀的影响同样不可忽视。

| Abstract: | Water and soil loss is an important physiognomy evolution course. Based on the theory of physiognomy erosion circulation and DEM analysis used as the method in the research of valley physiognomy evolution, the period of physiognomy evolution of massif region in city of Jinan is divided into youth period and old period. The correlation of soil erosion potential danger and soil erosion intensity comprehensive index and physiognomy evolution period implies that both human activity and physiognomy evolution period are of importance in soil erosion. |
