| China has done a lot of investigations on the wild ornamental plant resources,and found out the species and distribution of wild ornamental plants,but the reports of the investigation are limited to the classification and description of the key species.In this paper,the characteristics of wild ornamental angiosperms in Shanxi were analyzed,including classification,floral characteristics,altitude distribution,florescence and so on.The following results are obtained:1、In the statistics of 393 species of wild ornamental angiosperm genera,ranked in the top three were Rosaceae,Ranunculaceae and Leguminosae,accounted for 8.5% of total genera,7.5% and 6%;Liliaceae,Gentianaceae,Labiatae,Orchidaceae,Ligustrum,Saxifragaceae,Compositae,Thymelaeaceae,bear in winter,and were more than 5 Boraginaceae species;single genus 44.The 13 families accounted for only 18.1% species of wild ornamental angiosperms,contains 57.3% genera.2、There are more than 10 kinds of families,including the species accounted for 12 of the total number of 62.3%.Most species were Rosaceae,Leguminosae and Ranunculaceae,ranked the third.Three of the species accounted for 17.8% of the total species,7.4% and 6.4%.The rest is Caprifoliaceae,Liliaceae,Ligustrum,Gentianaceae,Saxifragaceae,Labiatae,Celastraceae,Aceraceae and orchids.3、On the statistics of 314 Shanxi wild ornamental angiosperm flower color,different color types for the proportion of total anthocyanins were yellow 29.2%,purple 20.5%,white 17.6%,red 12.5% green 10.6%,finally,blue 9.6%.4、To count the 61 families of plant color statistics,the species of Rosaceae species of red,yellow,white flowers are in the first row,purple flowers are Labiatae,other were green Celastraceae,blue Gentianaceae,pale yellow and yellow green bean Caprifoliaceae,Celastraceae,Acer,and Saxifragaceae,lavender the pale pink rose family.5、From the 11 kinds of color type distribution in general,Ranunculaceae color type are most,there are 9 kinds of legume followed by 8 categories,with 6 kinds of colors are respectively,Gentianaceae,Scrophulariaceae,Caprifoliaceae,Labiatae,Liliaceae and Ligustrum,with 5 kinds of colors are rose family,Orchidaceae,Jing Tianke,boraginaceae.6、The distribution of the 224 species of wild ornamental plants at altitudes,in accordance with the order of 1000 m,1000-1500 m,1500-2000 m,2000-2500 m and more than 2500 meters in the order of 9.8%,respectively,19.6%,15.6% and 22.3%.The results showed that the species distribution was most at 1500-2000 m above sea level.7、1500-2000 m altitude distribution of most plants,as the number of boundaries,above or below the altitude distribution of plants decreased below the elevation height distribution of plant families and the number of less.Less than 2500 meters above sea level in most species of Rosaceae,more than 2500 meters in most species of ranunculaceae.8、Distributed in the elevation of 2000 meters below the Shanxi wild ornamental angiosperm white flowers of the most species,respectively,at an altitude of more than 2000 meters of plants,red flowers the most;respectively,at the elevation of the blue flowers are least.9、The statistical results of the flowering time of the 173 kinds of the 331 kinds of plants,the flowering period is from March to October,the most flowering species in the year of May.According to the order of flowering species in the month,May,in June,in the year of July,in the year of August,in the year of March,in the year of September,in the year of October,the proportion of flowering species is 41.1%,respectively,29.6%,12.1%,10.3%,3.6%,1.2%,0.9%.The comprehensive study of wild ornamental plants in Shanxi can be determined,Rosaceae,Leguminosae and Ranunculaceae are rich in wild ornamental plants of three families;flower species from more to less are yellow,purple,white,red,green,and blue color type,Ranunculaceae is the most;below 2000 meters above sea level,most types of white flowers more than 2000 meters above sea level,red flower species,each elevation blue flowers and plants in the least;types of elevation between 1500-2000 meters and the distribution of up to 2500 meters below the altitude;most species of Rosaceae,more than 2500 meters in Ranunculaceae species;flowering distribution between March and October,blooming in May most species,October is the least. |
