Investigation Of Ancient And Famous Trees Survive In Middle Northern Shaanxi Provine

Ancient and famous trees are living human treasures, the existing forest resources ofprecious resources, heritage is not only the history of nature is valuable testimony. Record.Trees are basis of rare trees germplasm resources preservation and exploitation; regionalhistory and culture of the carrier; regional tourism industry premise; necessary foundation forthe development of the urban landscape. Protect them for the construction of regionaleconomic development has important significance.In this paper, first survival status of the northern part of Shaanxi Province OVTsliterature, etc. Historical conducted field research, filming, recording the image of status ofancient and famous trees Through the field investigation concluded that the poor status ofancient and famous trees survive in northern Shaanxi Province,176trees,39speciessurveyed, belong to26families, Which has six main species accounted for70.45%, mainlywith acacia trees, cedar, acacia, gingko, spruce. Ash and arborvitae mostly in the thousandyears, between the ages of90-5000years old trees change, the larger the magnitude of thechange. OVTs tree index its own age and living environment has a certain relevance. Ancientand famous trees in northern Shaanxi Province in4-30m height between the change indiameter between the0.42-4m, crown between the the3-20m. Most of the old trees as poorhealth, withered trees snags more prevalent, partial crowns of trees plant diseases and insectpests of more serious. Currently most of them growth potential weakness, the urgent need foreffective protection and management of them.Survey176ancient and famous trees in northern Shaanxi Province, located in the sixkinds of habitat types: namely between garden spots, unit schools, urban streets, the villagecourtyard, street bottom, mountain wilderness. Most of them living in a poor environment.Distribution of the most ancient and famous trees in the garden spot among; forest wilderness,there are many trees, but these trees do not get good protection measures; urban streets ofancient and famous trees rarely need to focus on. This trees have a large change in crown,gardens and other attractions have the largest and oldest trees, tree growth described here toget a better spatial extent.In the survey80%of the old trees have a good historical and cultural value, according toits own characteristics and historical value will be divided into four categories: King trees, Trees charm, Trees spectacle, Trees and flowers. Currently in northern Shaanxi ProvinceKings trees is16, trees charm has more than50trees, trees spectacle is more than20trees,flowers and trees more than10strains. They all have their unique charm story, associatedwith historical events or figures, or form associated with itself or with its old age related,these old trees carries important historical and cultural information. They witnessed thehistorical development of Shaanxi Province, recorded the precious historical information forus, showing the history of the development of Chinese civilization, records the regionalconstruction and political change, it also reflects the northern Shaanxi Province historicalcontext of the area and landscape features.In the summary, the presence of ancient and famous trees in northern Shaanxi Provinceprotect the four problems: OVTs listed are not unified, the address information is not detailed,the living environment is poor, poor landscape effects. The current analysis of the problemsdiscussed, and suggestions for Conservation and Utilization, Protection: make the treesgrading, classification protection; trees for long-term monitoring; trees endangered conductspecial studies or special protection; trees transplanting measures. Use: First, establishrelevant OVTs gene pool. Second, pay attention to aging trees and trees dying scientificresearch. Third, we should attach importance to the development of the value of productionof rare ancient and famous trees.
