Selection of Indigenous Plants in Roads in Northwestern Loess Plateau Area

[Objective] The aim was to study on resource utilization of indigenous plants in roads in order to solve resource shortage of indigenous plant in bioengi- neering. [Method] Based on northwestern loess plateau area, we conducted research on selection of indigenous plants and survey on the species which could live in adverse condition, mainly by surveying, with frequent tests as a supplement, to make a comprehensive observation and evaluation on plant combinations which are to be extensively applied. [Result] The research indicated that in central dividing strips, four arbors, including Platycladus orientalis （Linn.）Franco, Sabina chinensis, Sabinachinen- sis（Linn.）Ant., and Ulmus purnila L., and nine frutices, including Lycium chinense, Tamarix austromongolica, Rosa xanthina Lindl., Forsythia suspense, Atriplex canescens, Amygdalus triloba, Hippophae rharnnoides Linn., Arnorpha fruticosa L., and Syzygium aromaticum could be planted. In addition, Gleditsia sinensis Lain, Robinia pseudoacacia L, Elaeagnus angustifolia L., Rhus typhina, Salix babylonica, Salixmatsudana and Fraxinus chinensis, tall and strong, are suitable to be planted as border trees, presenting a good vision. Frutices, limited by height, are usually with more branches, which will provide a good landscape if grown with tall plants. Prunus dacidiana and Ulmus pumila L., prone to be damaged by insects, should be planted with other species to stop the infestation in space. [Conclusion] The research laid foundation for selection of indigenous plants in roads, providing references for resource shortage of indigenous plant for bioengineedng.

Ethnopharmacological Survey of Medicinal Plants in Baotou,Inner Mongolia,China

Objective To document the knowledge and the use of indigenous medicinal plants by traditional healers in Baotou,Inner Mongolia,China.Methods Data were collected from 112 randomly-selected interviewees using semistructured interviews in wild herbal plant collected from 2007 to 2010.The data from the interviewees were analyzed with two quantitative tools.With the informant consensus factor,the information homology was evaluated and with the fidelity level the most important species from the categories were found.Results One hundred and fifty-two species belonging to 112 genera in 48 families with medicinal values were recorded.The reported medicinal plants species were used to treat 63 kinds of diseases.And the medicinal plants in this district possessed significant potentials for their pharmacological activities in the context of ethnopharmacological knowledge,especially in the treatments of gastrointestinal,dermatological,and cardiovascular diseases.Conclusion In this work,152 medicinal plants with their ethnopharmacological information are reported.This study demonstrates that many species play an important role in healing practices among inhabitants from Baotou.More ethnopharmacological information of Mongolian medicinal plants should be gathered and documented in further studies,which is a fundamental step toward developing efficacious natural drugs for various diseases.
