The Evaluation Of Introducing Foliage Trees's Adaptability Of Yingongshan Mountain In Qing Shuihe Of Hohhot

With the further improvement of the social and human's needs,city garden greening has increasingly become an important symbol of modernization of a city.Riching and introducting landscape of plant species has become an inevitable trend.In this paper I researched the adaptability of the Introduced Foliage trees in Yingong mountain park of the Qingshuihe such,as Ginkgo biloba?Rhus typhina Nutt?Prunus Cistena?Fraxinus chinensis Roxb?Amygdalus persica L.var.persica f.atropurpurea SchneidCotinus?coggygria 'Purpureus'?Acer mono Maxim and Singixmoversudanyfacv.Pewndula.Based on a comprehensive survey?sampling survey and phenological observation method to suevey the growth and development(growth vigor?whether or not can blossom)?ornamental value(flower?fruit?leaves and the form of the tree)and growth and stress resistance of the tree(survival rate?frost damage rate and plant disease rate)to appraise the adaptability.First,through the combination of qualitative analysis with quantitative analysis method to establish a reasonable scientific comprehensive evaluation system for a single index factor analysis of the adaptability of the investigation,the factor of each single index fall into three grades,excellent,good,bad and give score,then according to the size of the different index factors influence in the adaptability and again,weights of each index factor to draw a single index factor adaptation degree,finally comprehensive index method is adopted to improve the adaptability of comprehensive evaluation.The results showed that:in the 8 species investigated:adaptive tree species are Prunus Cistena and Fraxinus chinensis Roxb;Adaptive species in general is Amygdalus persica L.var,persica f.atropurpurea Schneid and Singixmoversudanyacv.Pendula;The poor adaptability of species are Ginkgo biloba?Rhus typhina Nutt?Cotinus coggygria 'Purpureus' and Acer mono Maxim.
