Evaluation Of Ornamental Plants And Applycition Of The Model

Wild ornamental plants were a sort of ornamental plants that are still in wild in naturalplaces,and they have many advantages,such as highly ornamental aesthetic values, strongadaptability,fewer pests,fewer diseases.They are resources for research and breeding newvarieties of ornamental plants.Tongbo Mountain nature reserve in Jiangxi provinceprovided special geographical location and suitable habitat for the wild ornamentalplants.During May and November,in2012,the wild ornamental plants had been widely andthoroughly investigated by using the method of typeical line-investigation.And based onthe inveatigation,qualitative and quantitative analysis and detailed evaluation were used toinvestigate the wild ornamental plants.The results were as follows:1According to the wild investigation,the wild ornamental plant resources of TongboMountain nature reserve are rich,and they consisted of482species,representing248generaand102families.All of these,there were8species of pteridophyta belonging to7genera,7families;8species gymnosperms belonging to7genera,4families;388species dicotyledonbelonging to187genera,82families;77species monocotyledon belonging to45genera,9families.2The analysis of genera composition showed that: The dominant families containing morethan10species were Rosaceae, Gramineae, Leguminosae, Fagaceae, Lauraceae,Theaceae,Compositae,Aceraceae,Hydrangeaceae,Liliaceae,Orchidaceae,Verbenaceae,Caprifoliaceae,Ericaceae.And the dominant genara with species beyond10were Acer(11species) and Prunus cerasus(9species).3The diversity of wild ornamental plants in Tongbo mountain nature reserve was analysedfrom different point of view which included species richness, life form,rarity,ornamentalcharacters and so on.The wild ornamental plant species are richness,and according todifferent parts of ornament,they were divided into flowering plants,ornamental fruitplants,ornamental leaves plants and ornamental posture plants,There are14species rareand endangered wild ornamental plants,and56species provincial key protection plants inJiangxi province.4In this paper,a set of comprehensive evaluation index system and model for wildornamental plants were eatablished,the model includes5layers,and a number of indicatorsbelow each layer,the total of indicators is37.5Apply Analytic Hierarchy Process method to evaluate the utilization value of wildornamental plants.60species with high ornamental value of flowers,fruits,leaves andposture plants were evaluated.35species of the wild ornamental plants in Tongbomountain with high development potention were strongly recommendation.And the resultcame out to be that Taxus chinensis var. mairei, Stewartia sinensis, Coriaria nepalensis,Fructus Manglietiae Yuyunensis and etc. had a great development and utilization potential.
