THE ZONAL DIFFERENTIATION OF SOIL ENVIRONMENTAL BACKGROUND VALUES AND CRITICAL CONTENTS IN GUANGDONG

The soil distribution in Guangdong is characterized by an obvious zonality, showing red soil, latored soil and latosol from north to south. This paper summarizes recent research results on soil element background values and heavy metal environmental capacity in the region, and discusses the differentiation pattern of the environmental background value and critical content of the main zonal soils in Guangdong.
