The core of soil geography is the study of soil changes in space and time,which aims in the prediction of soil behaviors under various ecosystems and human activities,and in the effective management of soil resources.The development of soil geography in China has experienced several important phases.In 1950s,regional soil reconnaissance survey and natural resource survey had laid a solid foundation for the recognition of the major soil types and their distribution laws.In 1980 s,just after the restoration of the nation's scientific activity,the launch of the second national soil survey programme had boosted the revival of soil geography in China,including almost all aspects of it such as soil genesis, classification,mapp ing and remote sensing.As a project emerged in that period,the study of "Chinese Soil Taxonomy" had prevailed nearly 20 years thereafter and had acted as an important engine of soil geography development in China.
