一、苗木價值的核心評估指標

　　1、 Core evaluation indicators for the value of seedlings

　　1. 生長指標

　　1. Growth indicators

　　胸徑：地面以上1.3米處樹干直徑，是定價的核心依據。例如，香樟胸徑每增加1cm，價格通常上漲15%20%（中國林業科學研究院數據）。

　　Diameter at breast height: The diameter of the tree trunk at a height of 1.3 meters above ground level is the core basis for pricing. For example, for every 1cm increase in the diameter at breast height of camphor trees, the price usually increases by 15% to 20% (according to data from the Chinese Academy of Forestry).

　　樹高與冠幅：直接影響景觀效果。如5米高廣玉蘭全冠苗比截干苗價格高30%50%。

　　Tree height and crown width: directly affect the landscape effect. A 5-meter-high fully crowned magnolia seedling is 30% to 50% more expensive than a dried seedling.

　　樹齡：珍貴樹種如銀杏，20年樹齡苗木價格可達同規格普通樹種的3倍。

　　Tree age: Precious tree species such as ginkgo can be sold for up to three times the price of ordinary tree species of the same specifications at 20 years of age.

　　2. 健康狀態

　　2. Health status

　　病蟲害、機械損傷會使價值降低40%60%。評估時需檢查葉片完整性（缺損率＜5%為優質）、根系發育狀況（土球直徑需達胸徑810倍）。

　　Diseases, pests, and mechanical damage can reduce the value by 40% to 60%. When evaluating, it is necessary to check the integrity of the leaves (a defect rate of less than 5% is considered high-quality) and the development of the root system (the diameter of the soil ball should reach 810 times the diameter at breast height).

　　二、市場與政策影響因素

　　2、 Market and policy influencing factors

　　1. 供需關系

　　1. Supply and demand relationship

　　稀缺品種如日本紅楓，2米高苗單價可達8000元，而常見國槐同規格僅300500元。

　　Rare varieties such as Japanese red maple can cost up to 8000 yuan per 2-meter-high seedling, while common Chinese locust trees of the same size cost only 300500 yuan.

　　地域差異明顯：北方油松價格比南方高約25%（《中國苗木市場年度報告2023》）。

　　There are significant regional differences: the price of Pinus tabulaeformis in the north is about 25% higher than that in the south (Annual Report on China's Nursery Market 2023).

　　2. 政策導向

　　2. Policy orientation

　　生態修復工程推動抗逆性樹種（如檉柳）需求，2022年起價格年均增長12%。

　　Ecological restoration projects are driving demand for stress resistant tree species such as tamarisk, with an average annual price increase of 12% starting from 2022.

　　三、專業評估方法對比

　　3、 Comparison of Professional Evaluation Methods

　　方法適用場景案例說明

　　Case study explanation of applicable scenarios for the method

　　成本法

　　law of costs

　　新培育苗木

　　Newly cultivated seedlings

　　計算3年生紫薇苗（含地租、人工）成本約180元/株

　　Calculate the cost of a 3-year-old crape myrtle seedling (including rent and labor) at approximately 180 yuan per plant

　　市場法

　　Market Law

　　流通量大品種

　　Large circulation varieties

　　參照本地市場同規格桂花成交價

　　Referring to the transaction price of osmanthus flowers of the same specifications in the local market

　　收益法

　　Income approach

　　果樹、經濟林

　　Fruit trees, economic forests

　　預估5年后蘋果苗年產果收益折現

　　Estimated discounted annual yield of apple seedlings in 5 years

　　四、操作流程標準化建議

　　4、 Suggestions for standardizing operational procedures

　　1. 實地測量：使用輪尺測胸徑（誤差±0.1cm），激光測距儀量樹高。

　　1. Field measurement: Use a compass to measure the diameter at breast height (with an error of ± 0.1cm), and use a laser rangefinder to measure the height of the tree.

　　2. 分級認證：依據國家標準劃分Ⅰ級（優質）、Ⅱ級（合格）、Ⅲ級（淘汰）。

　　2. Classification certification: According to national standards, it is divided into Level I (high quality), Level II (qualified), and Level III (eliminated).

　　3. 動態調整：每季度更新區域價格數據庫，參考中國苗木網等平臺成交均價。

　　3. Dynamic adjustment: Update the regional price database every quarter, referring to the average transaction price on platforms such as China Nursery Stock Network.

　　注：特殊價值附加（如古樹名木）需委托專業機構評估，其文化價值可能占總值60%以上。

　　Note: Special value additions (such as ancient and famous trees) need to be evaluated by professional institutions, and their cultural value may account for more than 60% of the total value.
