Jinsha river downstream hydropower project will be water under the gate, the project covers an area of a broader, there were a lot of ancient and famous trees range resources. For this kind of precious and scarce resources, local government and the project owners in all hope before water storage for protection, which can protect the limited resources and the species can beautify the environment. And protection must first master the resources of the whole situation, and learn about ancient and famous trees involved the comprehensive value size and protection measures of the feasibility of operational ease, the corresponding measures to protect them.In this article, the work closely with internal and external industry way, according to "every wood survey", at the request of jinsha river downstream hydropower project is ancient and famous trees submerged comprehensive inventory, thus mastered the bunches of trees species, tree height, DBH, crown breadth, growth potential, old, growth and location management responsibility unit such indicators, and set up the image database. Six of the general state of ancient and famous trees and the types and quantity, in different areas of the distribution, type, age characteristics and protection of ownership is analyzed.On this basis, this paper applied WangJiCheng (2011) of the ancient and famous trees comprehensive value evaluation method, the jinsha river downstream of the ancient and famous trees ecological value, the economic value and society value evaluation, obtains the ancient and famous trees strains the comprehensive value rating score height according to arrange order, the results show that:the jinsha river downstream submerged in the ancient and famous trees comprehensive value scored is not high, not more than60points. The highest score interval (50-60points) species have Ficus virens Aiton var. sublanceolata, Bombax malabaricum and Bischofia polycarpa; The minimum score interval (10to20points) species are Ficus virens Aiton var. sublanceolata; Score between interval (20to50points) are included in the most of the ancient and famous trees resources. Using the analytic hierarchy process (ahp) and Fidel method, the selection reflect the characteristics of the protection of resources protection grade, protection type and protection status, reflect the growth of ecological characteristic situation and the interference degrees and treetops ratio, and reflect the external conditions and habitat coordination and traffic conditions and other factors, setting up the index system, and to identify various index of the specific meaning and reference to their scores of each factor, obtains the strains of the ancient and famous trees measures to protect the feasibility score, its score height according to arrange order, the results show that:the jinsha river downstream measures to protect the ancient and famous trees feasibility between30-70points in between. By10points and one interval differentiate, which is divided into five sections, including scoring70points or more in the ancient and famous trees have17plants, including Dimocarpus longan, Ginkgo biloba and Phoebe zhennan with three tree species, accounting for3.70%of the total number of; Between40to60of the most between ancient and famous trees, accounting for77.39%of the total number of; Between30-40of the ancient and famous trees between less, only21,4.57%of the total number.Through the ancient and famous trees to plant the comprehensive value and protection measures of the feasibility study, for the next step to prepare the protection measures put forward. Scores of protection can serve as an important reference basis, in the actual operation process, can be integrated value and protection measures feasibility score, combining for comprehensive value and protection measures were higher score of the feasibility of the ancient and famous trees to focus and priority protection advice, to score were lower protection order and degree of attention followed advice.This paper puts forward the jinshajiang river actual four protection measures:one is to establish a perfect file management and monitoring system; Two is classified treatment measures:transplant protection, seedling instead of and gene from the body save; Three is discussed by, centralized transplantation after nearby and two ways of combining the transplant protection way; Four is perfect and implement the transplantation, protection and management system.
