Abstract The requirements and simple quality evaluation method of solid geochemical sampling are given in China's current norms. In order to more fully reflect sampling requirements, the authors have comprehensively analyzed and discussed the research results of sampling methods and sampling factors in China and abroad. From the two levels of sample and samples, the three dimensions of sample properties, space and time, the sampling compliance, representativeness, pertinence, uniformity and timeliness are used as the index system to measure the quality of solid geochemical sampling, and the representative and pertinent indexes are qualified. The new index has definite practicability for evaluating the quality of field sampling in geochemical sampling.
