Features: Based on the research on the migration and accumulation types of chemical components in loess strata, the author of this book established the theory of chemical component accumulation in loess. Guided by this theory, combined with methods such as chemical analysis, pollen analysis, particle analysis, electron microscope identification, and X-ray diffraction, the environmental changes since the formation of the Loess Plateau loess have been studied. The book focuses on the evolution of soil and climate over the past 700,000 years and the vegetation changes during the Late Pleistocene and Holocene. It identifies the weathered crust and subtropical brown earth developed in the loess, reveals the essence of loess and its formation patterns, and explores the control effects of major turning points in the Loess Plateau and ancient climate on the activity of sandstorms, the development of soil resources, and the enrichment patterns of groundwater.
