黄芩野生与栽培资源分布调查研究

目的调查黄芩野生与栽培植物资源现状，为其资源保护与可持续利用提供参考依据。方法在充分文献调研的基础上，对不同地区黄芩野生和栽培资源的地理分布、生长情况以及采收和消长等资源现状进行调查研究。结果黄芩野生资源主要分布在我国暖温带与中温带的干旱及半干旱地区，呈不连续的零星分布，其生境和群落特征多样、植株形态差异显著。栽培黄芩主要分布在山西、河北、甘肃、山东、内蒙古等地，栽培模式多样，各地黄芩资源产量和质量存在一定差异。结论黄芩野生资源的破坏与资源质量不稳定是黄芩资源的两大问题。为保护黄芩植物资源使其可持续利用，建议加强黄芩质量成因和质量控制研究，并做好制度性保障工作。

Resources Distribution Survey of Wild and Cultivated Scutellaria baicalensis Georgi

Objective To provide reference basis for protection and sustainable utility of S. baicalensis by a large scale of nationwide resources survey of Scutellaria baicalensis Georgi in China. Methods On the basis of literature research, survey was conducted on geographical distribution, resources reserves, recovery and growth of the resources status etc. of S. baicalensis. Results The wild resources of S. baicalensis was wildly distributed in the emperate zone in north of China and the distribution was discontinuous. Large differences were showed between different populations in entironment, coenotype and plant morphology. The cultivated resources of S. baicalensis were mainly distributed in Shanxi, Hebei, Gansu, Shandong provinces and Inner Mongolia autonomous region. There were diverse cultivation models and differences existed in production and quality in different regions. Conclusion Destruction of the wild resources and unstable of the resource quality were two main problems of S. baicalensis resources. It was suggested that researches on quality formation and control should be carried out, and institutional guarantee was essential to protect and sustainable use the plant resources of S. baicalensis.
