摘要：China is one of the multi-ethnic countries in the *** is common for the people in the ethnic areas are using two or more different languages in their social *** paper discusses the characteristics and regulations of the trilingual education of the Chinese indigenous people as well as the significance of the ethnic minority’s trilingual education against the globalization background from the perspective of socio-linguistics.

摘要：Concept of indigenous plant and ecological landscape was *** role of indigenous plants in urban ecological landscape design was analyzed,visual beauty,beautiful seasonal aspect,fragrance and charm of these plants were ***,the role of indigenous plants in creating landscape spaces,landscapes of time sequence and also regional landscapes was enhanced,and it was proposed that application of indigenous plants accorded with requirements of the conservation-minded ecological landscape *** selection of indigenous plants for the ecological landscape design was discussed,then the following points stressed:right trees should be selected for right land according to the actual eco-environment conditions;properties and functional needs of urban green spaces satisfied;indigenous plants with outstanding landscape ecological attributes selected;historical and cultural features of the city ***,attentions in the configuration of indigenous plants were given as(a) maintaining species diversity and simulating natural community structure;(b) coordinating relationship among plants according to the principle of "mutualism",focusing on color combination and changeful seasonal aspects.

摘要：[Objective] indigenous plants with favorable water and soil conservation effects were screened for the shrub planting.[Method] Suining-Ziyang-Meishan Highway in the hilly areas of central Sichuan Province was taken for example,through sorting out plant species investigated in the route planning,3 indigenous shrub species(Neosinocalamus affinis,Vitex negundo and Coriaria nepalensis) and 3 indigenous herbaceous species(Setaria viridis,Miscanthus floridulus,Artemisia argyi) were *** simulation experiment was adopted to compare runoff and sediment yields of different combination modes and ratios under constant rainfall intensity(20 mm/min).[Result] Different combination modes under constant rainfall intensity all showed better water and soil conservation effects than that of control group *** example,runoff appeared 1'-4'05"later,sediment yield reduced by 6.56-33.86 g *** all combination modes,runoff and sediment yield showed great difference after 20 min of constant rainfall,***+*** had the lowest runoff(1,700 ml) and sediment yield(60.71 g);C nepalensis+A. argyi had the highest runoff(1,920 ml) and sediment yield(84.02 g).[Conclusion] Given the same planting conditions such as side slope and seeding quantity,and also the same planting techniques,in the hilly areas of central Sichuan Province,the combination of *** and *** can greatly improve the water and soil conservation capacity of highway.
