| Ancient Gingko provincial scenic area of Tuole in Panxian Guizhou Province islocated in Guizhou province Panxian shiqiaozhen, properly Lok Estate, Pik Cave, DanxiaMountain Scenic Spot, the Gingko scenic and rhododendron forest area by the thePanxian city historical and cultural group, a humanistic Landscape group and four naturalsites with a total area of72square kilometers. The major landforms divided into karstkarst landforms, erosion-erosion landforms and erosion-erosion landform threecategories, with an average elevation of about1730m. The scenic area has a subtropicalwet spring and dry summer mild climate, annual average temperature of about15.2°C.The atmosphere in the region rainfall, the average annual rainfall is about1357.8mm,annual average sunshine approximately1593.8hours, annual average sunshinepercentage of36%, the average evaporation is1509.0mm, annual average relativehumidity of76%. Are in subtropical Yunnan-Guizhou Plateau semi-evergreenbroad-leaved forest, the vegetation is rich in resources.In this paper, each wooden gauging when the old trees the Ancient Gingkoprovincial scenic area of Tuole in Panxian Guizhou Province,with Strapping measuringits diameter at breast height, tree height altimeter measurements, measuring tape measurecrown width, with global satellite positioning system (GPS positioning) for each straintree latitude and longitude, altitude, and detailed records per plant habitats of the old trees,growth conditions, every tree will be numbered. Age determination combined with thegrowth cone Interview Survey to determine access to relevant information. The AncientGingko provincial scenic area of Tuole in Panxian Guizhou Province of old treesresources as the main object of study, the three old trees concentrated in the region,according to the non-probability sampling type confusion (Krebs,1989), judgmentsampling, four survey points total of12surveys block the formation of community life.According to the investigation of actual vegetation in the the ancient ginkgo provincialduly music Scenic sample is divided into three vegetation types of evergreenbroad-leaved forest, deciduous broad-leaved forest and coniferous forest. And inaccordance with the sampling method, collected a total of12survey points, survey pointsthe basic area of20x20m, a community classification, frequency analysis, the analysisof the vertical structure of community trees existing in the study to typical plantcommunities, The following results were obtained:1. Guizhou Panxian duly music ancient ginkgo provincial scenic area483existingold trees, belonging to11families,12genera and12species. The most number of trees Ginkgo ginkgo451, accounting for93.4%of the total number of trees; Second is the thepersimmon Ebenaceae11, accounting for2.3%of the total number of trees and cypresses,arborvitae10; once again, of the total number of trees2.1%; followed by FabaceaeSophora japonica2; Oleaceae Osmanthus2; each0.4%of the total number of trees.Old trees average crown width of195.3square meters, and the crown of the largest is837square meters. Crown more than701square meters with11, accounting for2.4%of thetotal;601-700㎡8, accounting for1.6%of the total; crown501-600㎡8, accountingfor1.6%of the total; crown401-500square meters with28, accounting for5.7%of thetotal; crown301-400㎡52, accounting for10.7%of the total; crown201-300㎡87,accounting for18.1%of the total; crown ranging from101-200square meters218,accounting for45.1%of the total; crown71of less than100square meters, accountingfor14.8%of the total. Old trees average tree height of18.1m, the tallest tree up to28mhigh tree in the21-30M of128, accounting for the26.6%of the total;11-20m,307,accounting for the63.3%of the total;1of10m48, accounting for10.1%of the total. Oldtrees average diameter at breast height72.1cm, maximum diameter at breast height of205cm, diameter at breast height200cm above five, accounting for1.1%of the totalnumber, diameter at breast height151-200cm64, accounting for the13.3%of the totalnumber of101-150cm of71, the total of14.6%;51-100cm of276, accounting for57.1%of the total;67less than50cm, accounting for13.9%of the total. Judging from thegrowth potential, strong growth of395, generally for48the poor24endangered16,accounting for81.8%,9.9%,4.9%,3.4%. From the distribution characteristics, old treesto Qunsheng the main, a total of32trees group,452old trees Qunsheng, accounting for93.6%of the total number of trees; scattered old trees of31, accounting for6.4%of thetotal number of trees. From the age and level of protection, the total of the national levelof old trees of50, accounting for10.4%of the total number of old trees, two old trees of433countries, accounting for89.6%of the total number of old trees.2of63old trees the Ancient Gingko provincial scenic area of Tuole in PanxianGuizhou Province community of old trees vegetation, including properly Le Village, onthe stone bridge, stone bridge, Coriaria concave11local resource survey point,investigated a total of95kinds of plants belonging to59families,86genera, includingold trees,12species,83kinds of associated tree species. Old trees, ginkgo (Ginkgobiloba)41(32) ginkgo trees group persimmon (Diospyros kaki), followed by11,10distribution small number. The point of view of the system of classification, gymnosperms4families,6genera,6; dicots44families,68genera,77species; monocots7families,8genera,8; ferns4families,4genera,4species. The results showed that the12vegetation samples divided into evergreen broad-leaved forest, deciduousbroad-leaved forest and coniferous forest vegetation12communities. The communityname in the form of the tree layer-shrub layer-herb layer named12communities are:(1)heather-the peach+loquat-the E. adenophorum+car plantain community;(2)sweet-scented osmanthus-Pyrus+gold the plum-the E. adenophorum+mugwortcommunity;(3) Ginkgo-peach+Pear-Pteris+sweet potato Yung communities;(4) themulberry-pepper-Pteridaceae, community;(5) of acacia-pepper+white, pears;(6) thewalnut-Pear-Pteridaceae community;(7) Yunnan Catalpa-loquat+peach-ginger+belladonna community;(8) Sophora japonica-Loquat+peach-ginger+belladonnacommunity;(9) Ginkgo-loquat+peach-Guanzhong community;(10) persimmon-pepper+Pyracantha community,;(11) Keteleeria-Camellia+Jin Simei-Artemisia argyi,+Eupatorium adenophorum communities;(12) side The Park-Pyrus-the mugwort+Pteridaceae community. And the investigation into the plant using frequency analysismethod to analyze the importance of the area plants, concrete results: study growth trees,ginkgo, the number of occurrences of62, frequency values up to98.4%in all treesaccounted for an absolute advantage; shrubs in the highest frequency Jin Simei, the valueof the frequency of36.5%, followed by coral bean, the frequency value of31.7%; herbalPteridaceae38times, frequency60.3%, followed by the frequency of mugwort alsoreached41.3%.3by the characteristics of old trees the Ancient Gingko provincial scenic area ofTuole in Panxian Guizhou Province from the literary culture, ecological culture, tourismand culture, medicinal culture, food culture, old trees and cultural analysis, scenic areascenic resources distribution and classification survey, qualitative and quantitativeevaluation on landscape resources at all levels monomer and Analytic Hierarchy Process,drawn Scenic resources within relatively concentrated and rich, with cliffs, steep peaks,caves, warm springs,54River, natural forests, Mingmugushu ancestral cemetery, ancienttemples, relics and other types of natural scenery and cultural scene, has the ornamentalvalue, historical and cultural value and scientific value. Further to achieve eco-efficiency,high degree of perfection of the social, economic integration and coordination ofdevelopment.4combined with Guizhou Panxian duly music ancient ginkgo provincial scenic area of old trees protect the recommendations and implement measures to protect the statusquo, based on the problems further. |
