在浙江省古树名木资源普查的基础上,采用层次分析法,考虑生态经济、景观美学、社会文化、科学研究四大因素,构建古树名木价值评估体系,并按评估指标赋分标准对古树评分,参考市场价值,对全省古树名木资源综合价值进行定量评估,进而分析其总体分布情况和市域空间分布特征。研究结果表明:浙江省古树名木的综合价值为7 246.05亿元,其中,生态经济价值为787.10亿元,景观美学价值为3 548.68亿元,社会文化价值为1 091.18亿元,科学研究价值为1 819.09亿元,四者之比为1∶4.51∶1.39∶2.31。浙江省古树名木综合价值市域分布总体不均衡,呈西南向东北递减的分布格局,两个高价值聚集区为绍兴会稽山脉区域及丽水国家公园区域,东部平原及沿海地区为价值洼地。通过不同区域之间的横纵向比较,可以从价值的视角,揭示古树名木资源分布的特点,可为浙江省各级政府部门科学制定古树名木资源保护发展战略规划及科学决策古树名木保护资金投入提供客观依据和对策建议。

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.
