Climatic and Anthropogenic Impacts on Soil Formation

Abstract

Soil succession directly records the information of environment and land use change, which is one of the important issues in global climate change research. In this paper, the authors investigated the soil samples and comparing their physical and chemical properties of soil diagnostic horizons. Results indicated that the Cum-ustic Isohumisols and Eum-Orthic Anthrosols had the same profile pattern, Ap-Bc-Bt/A-Bk-C. The characteristic temporal and spatial change of Ap horizon reflected several thousand years of dryland farming history in Weihe valley, but only several hundred years of dryland farming history on loess tableland.
