内容简介
本书对黄土高原水土流失区降雨侵蚀产沙与黄河输沙的时空分布特征、变化规律以及相互间的关系进行了系统研究。主要包括:降雨特征与降雨侵蚀力、中小流域降雨分布的不均匀性与点面关系、侵蚀产沙的区域分异与年际变化、不同空间尺度的雨沙关系、黄河泥沙的变化特征及趋势分析等。这是作者“八五”攻关课题研究的最新成果,可供有关研究黄土高原水土保持、环境、水文、泥沙、自然地理等方面的专业人员及高等院校有关专业师生参考。
BRIEF INTRODUCTION
The temporal and spatial distribution of rainfall,erosion,and sediment yeild on Loess Plateau and the sediment transportation in the Yellow River Basin and their relationships systematically studied in this book.It mainly includes rainfall characteristics,rainfall erosivity,nonuniformity of rainfall distribution and relation between point and areal of rainfall in medium and small watershed,regional variation and annually change of erosion and sediment yeild,relationship between rainfall and sediment on different area scale,the sediment yeild change and its tendency in the Yellow River Basin.
This book is suited for scientific workers,teachers and students who are engaged in those fields such as soil and water conservation,erosion environment,hydrology,sediment and physical geography,etc.
