广西宁明县肿节风资源调查

Resources Investigation of Sarcandra glabra in Ningming County of Guangxi

为更好保护和开发利用广西宁明县肿节风药材资源,按《全国中药资源普查技术规范》规定的调查程序和方法对宁明县境内肿节风的资源与分布现状、群落特征、产销情况等进行了较详细的调查。结果表明:宁明县肿节风主要分布在桐棉乡、那楠乡、峙浪乡等地,分布范围在21°42′18.96′′~22°03′13.58′′N,107°27′27.43′′~107°27′39.17′′E之间,分布面积为1693.34km2,生于海拔162m^697m沟谷或山坡林下,空气相对湿度70%~80%。植被类型为针叶林、阔叶林,土壤类型为赤红壤、红壤,pH值5.7~6.6。调查发现,宁明县肿节风药材资源丰富,总蕴藏量约280907.8kg,但由于受开荒造林的影响,分布范围、面积逐年减少,建议加强保护宁明县肿节风野生资源的同时扩大人工种植规模,促使该县肿节风资源可持续利用及产业化发展。

In order to better protect, develop and utilize the resources of Sarcandra glabra in Ningming County, Guangxi, the resources and distribution status, community characteristics, production and marketing of Sarcandra glabra in Ningming County were investigated in detail according to the investigation procedures and methods stipulated in Technical Standards for the National Survey of Traditional Chinese Medicine Resources.
