Abstract
Relying on the"Comprehensive Survey of Natural Resources in the Middle Reach of the Yellow River,Jin-Shaan-Yu Golden Triangle(Shaanxi Section)",and based on the"Program for Classification of Ground Surface Substrate(for Trial Implementation)(2020.12)of the Ministry of Natural Resources",and on the basis of systematically collecting,studying and comprehending the results of the research on ground surface substrate surveys in China,a pilot surface substrate survey was conducted in the Weinan Municipal Area at a scale of 1∶250,000 m.Additionally,a pilot surface substrate survey was conducted in the Huayin Area at a scale of 1∶50,000 m.The exploration of the surface matrix survey method and technique in Shaanxi province has yielded a number of significant new achievements,methods,and insights.This represents the first time that this particular approach has been examined in any detail,and the results have been highly promising.
