ABSTRACT
This study was aimed to investigate the qualitative and quantitative distributions of Lycium ruthenicum resources in the middle and lower reaches of Heihe River, for providing scientific evidence for the protective utilization of the resources in the corresponding geographic region. The outdoor sample plot and quadrat survey, literature search, sample collection, in-house identification and classification were performed by route surveying and visiting to the local natives and/or herb farmers based on the current distribution data of the L. ruthenicum resources in the middle and lower reaches of Heihe River. The distributive pattern of the resources was analyzed using ArcGIS program. The data regarding the category/distributed area and the genetic resources of the L. ruthenicum were collected. The data collected in this study may provide the scientific evidence for the protective utilization of the L. ruthenicum resources in the corresponding geographic region, allowing for the avoidance of the ecological environment from being damaged by improper utilization.
