The Study On Hunan Wild Woody Ornamental Plants Diversity Protection And Utilization

Hunan is at the middle of subtropical zone,the nature condition is superiority that it breeds abundant of wild woody ornamental botanical resources. In accordance with material concerned statistic, analysising that the main features of hunan province arbor ornamental plant diversity are as follows:(1)rich resources; a great variety of species; distinctive botanical geography;various types; can meet the current developing request of urban landscape;(2)dispers concentrated;such as Michelia,Rhododendron,Actinidia large genus have plenty of species; (3)the valued of ornamental feature is high, as of Davidia involucrata,Bretschneidera sinensis, etc. (4)famous flowers and endemic species are a lot; excellent conditions of historical geography, it was provided with east asian specialties,chinese specialties,east asian—muskey specialties simultaneily, woody plant flora are various; (5)the unity adaptive capacity of plant is better and easy to introduce and foster broadly for landscape. This text observe and note the wild woody plant with ornamental characteristic and fitness for introduction by broad investigation during hunan main areal,landscape greenbelt and famous scenic site, recommend sixteen wild woody ornamental plants in the future landscape developing bases field survey and individual zoology for introduction,which will promote the landscape plant develop toward diversification,localization and specialize step by step,including Rosaceae,Theaceae,Aguifoliaceae,Caprifoliaceae,Aceraceae,Ericaceae, etc.big family which have high ornamental value and percentage of Chinese plant species, their view spend,view fruit,view leaf,view performance ornamental characteristic reflect the wild woody ornamental plant resources diversity of hunan province.it is also propitious to wild woody ornamental plant especially for severe ornamental plant resources preservation and utilization, they have broadly use in landscape as roadside trees,shade tree,the tree of view alone,flower and plant bush,green fence,ornamental forest, it will make the wide variety of kinds get properly exploitate and applicate in the landscape. Wild woody ornamental plant resources in Hunan are abundant,which are available for development and utilization,the prospect is abroad,according with the situation of our country.Has analized that taking attention to preservation at the same time of plant resources investigation work,strengthen the introduction and domestication research and make the preservation and application integrated, which rich the landscape plant diversity and constitute the manpower plant community to make of city ecological system and stimulate the circulation of substance and energy,accelerating the urban step of ecological landscape construction.
