Abstract:

Based on the survey of ancient and famous tree resources in Zhejiang Province,the analytic hierarchy process(AHP)was used to construct the value evaluation system of ancient and famous trees considering the factors of ecological economy,landscape aesthetics,social culture and scientific research.The ancient trees were scored according to the evaluation index scoring standard,and the comprehensive value of ancient and famous tree resources in the province was quantitatively evaluated with reference to the market value,and then the overall distribution and urban spatial characteristics were analyzed.The results show that :The comprehensive value of ancient and famous trees in Zhejiang Province is 724.605 billion yuan,the ecological economic value is 78.710 billion yuan,the landscape aesthetic value is 354.868 billion yuan,the social and cultural value is 109.118 billion yuan,and the scientific study value is 181.909 billion yuan.The ratio of the four is 1∶4.51∶1.39∶2.31.The comprehensive value distribution of ancient and famous trees in Zhejiang Province is generally uneven,showing a decreasing distribution pattern from southwest to northeast.The two high-value gathering areas are Shaoxing Kuaiji Mountain Area and Lishui National Park Area,and the eastern plain and coastal areas are value depressions.Through the horizontal and vertical comparison between different regions,the characteristics of the distribution of ancient and famous tree resources can be revealed from the perspective of value,which can provide an objective basis and countermeasures for the government departments at all levels in Zhejiang Province to scientifically formulate the strategic planning for the protection and development of ancient and famous tree resources and scientific decision-making on the investment of ancient and famous tree protection funds.
