Study On Angiosperm And The Resources Of Wild Ornamental In Forest Park Of Jiufeng Mountains

The Jiufeng Mountain Forest Park is located in the south TaiHang Mountains ofSheXian area, the western mountains of Handan with layer and upon layer of peaks andknolls and many ravins. The height above sea level of the Mountain is at an altitudeof between500-1898.7m. There are significant differences between the light, heat, timeand space. The vegetation types of the region belong to the xerophytic flora of NorthChina and the half xerophytic shrub grassland forest meadow vegetation flora is veryimportant theoretical and practical significance to the protection of area ecologicalenvironment of Handan City and Hebei Province.In this paper, it was studied that geographic distribution of the angiosperms,floristic composition, families and genera geography composition, endemism andecological, life form and vegetation types in Jiufeng Mountain Forest Park. It wasdiscussed the plant species division and its main characteristics, the rare and endangeredplant species and conservation status. The results as follows:1. There are104families of angiosperms,419genera,690kinds (includingsubspecies units) in the Jiufeng Mountain Forest Park. The percentage Jiufeng MountainForest Park’s plant families, genera and kinds in Hebei province is83.2%,59.4%,34.5%. It is one of the regions which have the most abundant diversity of wildangiosperms in Hebei Province. In accordance with the dominant family (genus),which constitute the appropriate flora species composition of the body.8families are22species of dominant families, the percentage of the total number of subjects flora is7.6%;14genus are more than10families of dominant species, the percentage of thetotal flora genus is3.3%. The phenomenon of flora advantages is obviously.2. Five distribution types in the Forest Park with the rich flora on the basis ofWuzhengyi’s point on China seed plant distribution. There are92Pantropic Temperategenus (which account for22.0%of the total);42Northern Temperate genus (thataccount for10.0%). The data shows that the distribution types have significanttemperate properties, which combine both north temperate and tropical nature. 3. The Jiufeng Mountain Forest Park’s plant is provided with the complicacy andantiquity of origin. The single families account for the bigger than columns in thedistribution types. There are41single families (account for39.4%of the total sections),and212single genus that is50.5%of the total genus in this area.4. The characterization of subject is a decisive factor in the characteristics ofdistribution types. There are9typical genus that substitute cosmopolitan genus,13typical families which include2pantropicones and10temperate families; There are8typical genus which reflected distinctive temperate trait of the flora including1temperate genus and1East Asia and North America disjuncted genus,6north temperategenus5. Life form is the reflection of natural conditions in certain areas, which is theresult of the plant adapt to the habitat in the growth process. The Jiufeng MountainForest Park has54species Liana (which account for12.9%of the total species), whichis the super species in this area,102species wooden plant account for24.3%,260species herbage account for62.0%in this area.The phenomenon of trait of distinctivetemperate is obviously.6. There are56families,168genus as the wild ornamental plants resources in thearea. The angiosperm includes46families,129genus; There are22genus inCompositae and17genus in Ranunculaceae. Application of wild ornamental plantresources is play a crucial role on increasing the city richness.
