Study on estimating reserves of wild Seutellaria baicalensis in Inner Mongolia region based on 3S technology / 中草药

ABSTRACT

Objective: To establish the reserve estimation model, which can estimate the reserves of the wild Scutellaria baicalensis in Inner Mongolia region. Methods: Combined 3S technology with the traditional field survey methods, four habitat factors (vegetation type, altitude, rainfall, and temperature) have been selected as indicators for categorizing the habitat region of Inner Mongolia. According to the habitat suitability of wild S. baicalensis in Inner Mongolia region, stratified for each indicator, all indicators are divided into the most suitable, suitable, less suitable, and unsuitable four layers. Each layer in a simple random sampling method conducted field surveys. Results: Finally, the method and model to estimate the reserves in Inner Mongolia have been established. This model has been used to estimate the reserve of wild S. baicalensis in Inner Mongolia. The total number of wild S. baicalensis in Inner Mongolia is 19000 tons. Conclusion: It can provide an important parameter for the fourth national survey of Chinese materia medica (CMM) resources and the estimation of CMM resources based on 3S technology by multiple spatial scales model.
