%X This book is a textbook that systematically discusses the basic theories and applications of pedology. It covers the basics of geology and geomorphology, the origin and evolution, composition and properties, classification and geographical distribution of soil, and the genetic characteristics of typical soil types in various natural zones. and agricultural utilization. The book consists of three major parts: the first part introduces the crustal structure, weathering process and landform classification; the second part systematically expounds the soil-forming factors, soil organic matter, mechanical composition, physical and chemical properties, soil colloid and absorption capacity, soil solution and fertility concept; The third part describes the occurrence process, distribution rules and agricultural evaluation of various types of soils according to natural zones (tundra, taiga, forest grassland, semi-desert, desert, subtropical and mountainous areas, etc.), and discusses swamps soil, saline soil, floodplain soil, soil erosion and prevention, as well as soil mapping and land evaluation methods. Each chapter is accompanied by laboratory assignments, practical exercises, and review and thinking questions. This book is aimed at students and agricultural workers majoring in soil science and related majors in agricultural colleges and universities.
