1. The investigation of Chinese medicine resources is an important link to protect Chinese medicine resources and promote the development of Chinese medicine industry. The commonly used survey methods mainly include literature survey, field survey and statistical analysis. These methods have different differences and connections in data sources, survey objects, survey contents and survey methods. Different investigation methods have different advantages and disadvantages. In practical application, it is necessary to comprehensively consider the applicability, feasibility and efficiency of various methods and choose the appropriate method for investigation.
2. At the same time, in order to improve the reliability and accuracy of the survey results, it is necessary to combine various methods for comparison and verification. Investigation of traditional Chinese medicine resources is the basis of sustainable development of traditional Chinese medicine industry. Adopting reasonable investigation methods and means can better understand the present situation and development trend of Chinese medicine resources and provide scientific basis for the planning and management of Chinese medicine industry.
Comparison and selection of investigation methods of traditional Chinese medicine resources;
1. literature investigation: literature investigation is to understand the distribution, quantity and utilization of Chinese medicine resources by collecting, sorting out and analyzing relevant literature. The advantages of this method are wide investigation scope, large amount of information and low cost. The disadvantage is that the data source is indirect and may be biased, which needs to be compared and verified by other investigation methods.
2. On-the-spot investigation: On-the-spot investigation refers to the direct collection, observation, analysis and evaluation of traditional Chinese medicine resources through interviews, questionnaires and sampling surveys. The advantage of this method is that the data is true and reliable, and the field information can be obtained, which is helpful to find problems and formulate countermeasures. The disadvantages are limited investigation scope, high cost and large human error.
3. Statistical analysis: Statistical analysis refers to the classification, induction, analysis and prediction of traditional Chinese medicine resources by collecting and processing a large amount of data and information, using mathematical statistics and computer technology. The advantage of this method is that it can quantitatively analyze and find the laws and trends, which is more objective and scientific. The disadvantage is that it needs enough data support and is prone to over-fitting or over-simplification.
