甘肃省子午岭药用植物资源调查

目的：调查庆阳市子午岭林区药用植物资源,为规模化人工栽培提供科学依据。方法：对庆阳市子午岭林区药用植物采取文献调查、走访调查等方法进行调查。结果：药用植物的分布与森林覆盖面积、密度有关,从南向北逐渐减少;耐寒、耐旱药用植物大多生长在向阳山梁或半山坡,喜水或全草类生长在川台、河谷地,药用乔木或灌木生长在阴坡或沟掌,蕨类生长在山谷森林覆盖的林下;紫斑牡丹、穿山龙、苦参、甘草、干漆、五倍子、黄芩、酸枣仁、款冬花、槲寄生、苍术、马兜铃、泽泻、秦艽等为蕴藏量较大的野生品种。结论：本调查发现未载入庆阳市中草药历史普查记录的共计86个品种,具有重要的药用和食用价值,急待研究开发利用。

Investigation on Medicinal Plant Resources of Ziwu Ridge in Gansu Province

Objective： To provide scientific evidence for artificial cultivation in large-scale through surveying medicinal plant resources of Ziwu ridge in Qingyang municipality. Methods： Medicinal plants of Ziwu ridge were surveyed by literature and visiting. Results： The distributions of medicinal plants were related to forest-covering area and the density, they were decreased gradually from the south to the north; cold-resistant, drough-tolerant medicinal plants were mostly adaptable to sunny ridge or hillside, hydrophilous or herba adapted to terraces, medicinal macrophanerophytes or bush grew in shady slope, fern grew under the trees covered by the forest; Zi Ban Mu Dan（Paeonia rockii）, Chuan Shan Long（Dioscorea nipponica Makino）, Ku Shen（Sophora flavescens）, Gan Cao（Glycyrrhiza uralensis Fisch.）, Gan Qi（Toxicodendron vernicifluum）, Wu Bei Zi（Rhus chinensis Mill.）, Huang Qin（Scutellaria baicalensis Georgi）, Suan Zao Ren（Ziziphus jujuba Mill.var.spinosa）, Kuan Dong Huan（Tussilago farfara L.）, Hu Ji Sheng [Viscum coloratum（Kom.） Nakai], Cang Zhu [Atractylodes lancea（Thunb.） DC.], Ma Dou Ling（Aristolochia debilis Sieb. et Zucc.）, Ze Xie（Alisma plantago-aquatica Linn.）, Qin Jiao（Gentiana macrophylla Pall.） and others were abundant supplies of wild varieties.
