| Jinsixia National Forest Park is located in the south of the Qinling Mountains connecting on the north slope of Ta-pa Mountains, is the intersection zone of North-South plant flora in China. The park has beautiful landscape and abundant vegetation resources. Through the investigation of wildlife plants in Jinsixia National Forest Park, we did a system research on seed plants flora and wildlife resource plants. The results is showed as follows:(1)Abundant plant species. There are 120 families, 476 genera and 928 species wild seed plants, Among their, the gymnosperm plants have 4 families 6 genera and 10 species, dicotyledonous plants have 104 families, 401 genera and 793 species, monocotyledonous plants have 12 families 69 genus 125 species. 7 newly recorded species, a newly recorded genus are found in the park.(2)The floristic components were diverse. Among the family composition, the mono-specific family and oligo-specific family were the majority, but the main resource species are concentrated in the multi-specific family. The genera composition are similar to the family composition, the mono-specific genera and oligo-specific genera are the most, however, the species of the genus are mainly concentrated in the genus of 2 to 5 species.(3)The flora elements are various, also has the temperate region features. The geographical elements of families have 9 areal types and 9 areal subtypes, the geographical elements of genera have 15 areal types and 16 areal subtypes, the geographical elements of the flora are comparatively complex. Among which the genera of temperate are the dominant areal types, and among which the families of tropical are the dominant areal types.It is indicated that the flora of the park has obvious temperate nature and tropical origin, and it also reflects its transitional function in the flora of North and south. Only one endemic familiy and 17 endemic genera in the park, endemism is not obvious.(4)The flora is ancient origin, but also younger elements. The park distributed many angiosperms species, such as Pinaceae, Magnoliaceae, Ranunculaceae, Salicaceae, Fagaceae and so on. In addition, the mono-specific genera and oligo-specific genera are the most, parts of them are from the ancient taxa, but the more species are the younger group which adaptation to climate.(5)According to the comparison of R/T(tropic genera R, temperate genera T) and the analysis of the floristic spectrum, it shows the flora of the park has obvious temperate properties, which is relatively similar with the flora of Huoditang, Qingmuchuan and Chang-qing National Reserve, especially Qingmuchuan National Reserve, this is because they have the similar geographical location and similar ecological environment.(6)Rare conservation plants are abundance. The investigation showed there were 17 national key protected species, among them, 8 rare species, 5 endangered species; the first class were 2, the second class were 8, the third class were 7. There were 9 provincial key protected species, among them, 3 endangered species, 2 endangered species, 4 rare species.(7)Resource plants are in rich. According to statistics, there are 848 kinds of resource plants in the park, which accounts for 91.38%. This resource plants has divided into 9 categories. Including medicinal plants 561 species, ornamental plants 522 species, fiber plants 71 species, starch pants 38 species, protein plants 59 species, oil plants 87 species, forage plants 152 species, aromatic plants 39 species, tannin plants 54 species.(8)Integrated assessment model was made using the methods of Analytic Hierarchy Process. Quantitative assessments of wild medicinal plants and ornamental plants has been completed. The results show that, 53 species of ornamental plants are assessed as level I, 172 as level II, 94 as level III. In medicinal plants, 109 species of wild medicinal plants are assessed as level I, 256 as level II, 196 as level III. |
