森林資源作為陸地生態系統的核心組成部分,兼具生態效益、社會效益與經濟效益,其資產化評估是推動生態文明建設、優化資源配置的關鍵環節。本文基于現行技術規范與實踐需求,系統解析森林資源資產評估的核心方法及其應用場景,旨在為行業提供理論參考與實踐指導。
Forest resources, as a core component of terrestrial ecosystems, have ecological, social, and economic benefits. Their assetization evaluation is a key link in promoting ecological civilization construction and optimizing resource allocation. This article systematically analyzes the core methods and application scenarios of forest resource asset evaluation based on current technical specifications and practical needs, aiming to provide theoretical reference and practical guidance for the industry.
一、評估方法體系構建
1、 Construction of Evaluation Method System
根據《森林資源資產評估技術規范(試行)》及《資產評估執業準則》,森林資源資產評估以市場法、收益法、成本法為基礎,結合資源特性衍生出多元化技術路徑。
According to the "Technical Specifications for Forest Resource Asset Evaluation (Trial)" and the "Professional Standards for Asset Evaluation", forest resource asset evaluation is based on the market method, income method, and cost method, combined with resource characteristics to derive diversified technical paths.
1. 市場法:基于市場交易的價值發現
1. Market approach: Value discovery based on market transactions
市場法通過比對近期同類資產交易案例,經差異修正后確定評估值。其核心在于選取3個以上參照案例,通過立地質量、地利等級、物價指數等調整系數量化差異。例如,林地資源評估中,市場成交價比較法以單位面積交易價格為基準,結合立地質量調整系數(反映土壤肥力、坡度等因素)和地利等級調整系數(衡量采運成本),通過算術平均或加權模型計算評估值。該方法適用于交易活躍的區域,但要求參照物與評估對象具有高度可比性。
The market approach determines the evaluation value by comparing recent similar asset trading cases and adjusting for differences. The core lies in selecting three or more reference cases and quantifying differences through adjustment factors such as site quality, land use grade, and price index. For example, in forest resource assessment, the market transaction price comparison method uses the unit area transaction price as the benchmark, combined with the site quality adjustment coefficient (reflecting factors such as soil fertility and slope) and the land use grade adjustment coefficient (measuring transportation costs), and calculates the assessment value through arithmetic mean or weighted model. This method is applicable to areas with active trading, but requires a high degree of comparability between the reference object and the evaluation object.
2. 收益法:基于未來收益的現值測算
2. Income approach: calculating the present value based on future income
收益法通過預測資產未來收益并折現至評估基準日,體現資源的經濟產出能力。針對林木資產,收獲現值法將輪伐期內各年凈收益(如木材銷售收入扣除營林成本)按資本化率折現;年金資本化法則假設林地產生穩定年收益,以年平均地租與投資收益率之比計算價值。對于異齡林,周期收益資本化法需結合比例系數法或剩余價值法分割林地與林木價值。該方法要求收益預測具有可靠性,適用于成熟林或具備穩定收益預期的資源。
The income approach reflects the economic output capacity of resources by predicting the future returns of assets and discounting them to the valuation reference date. For forest assets, the present value of harvest method discounts the net income of each year during the rotation period (such as wood sales revenue minus forest management costs) at the capitalization rate; The capitalization rule of annuity assumes that forest land generates stable annual returns and calculates its value based on the ratio of annual average land rent to investment return rate. For forests of different ages, the cyclic income capitalization method needs to be combined with the proportional coefficient method or residual value method to divide the value of forest land and trees. This method requires reliable income forecasting and is suitable for mature forests or resources with stable expected income.
3. 成本法:基于投入成本的價值重構
3. Cost method: value reconstruction based on input cost
成本法以重置或維持資產所需成本為基礎,適用于幼齡林或特殊保護林。重置成本法通過計算各年度營林投入(含工資、物資、地租等)的現值累積,結合林分質量調整系數(反映生長狀況與立地條件)確定評估值。林地費用價法則聚焦林地取得與改良成本,適用于未經營林地的初始估值。該方法強調歷史成本的可追溯性,但需注意通貨膨脹與折舊因素的修正。
The cost method is based on the cost required to reset or maintain assets and is applicable to young forests or special protected forests. The reset cost method calculates the present value accumulation of forest investment (including wages, materials, land rent, etc.) for each year, and determines the evaluation value by combining it with the forest quality adjustment coefficient (reflecting growth status and site conditions). The forest land cost pricing method focuses on the acquisition and improvement costs of forest land, and is applicable to the initial valuation of unmanaged forest land. This method emphasizes the traceability of historical costs, but attention should be paid to the correction of inflation and depreciation factors.
二、評估對象的差異化應用
2、 Differentiated application of evaluation objects
森林資源資產涵蓋林木、林地、森林景觀等多類載體,其評估需結合資源特性選擇適配方法。
Forest resource assets cover multiple types of carriers such as trees, forest land, and forest landscapes, and their evaluation needs to be based on the characteristics of the resources to select appropriate methods.
1. 林木資產評估
1. Forest asset evaluation
用材林、經濟林等不同林種需采用差異化策略。成熟林因具備明確采伐收益,優先采用市場價倒算法(以木材銷售收入扣減成本利潤)或收獲現值法;幼齡林因收益周期長,更多依賴重置成本法。林分質量調整系數是關鍵參數,需綜合樹高、胸徑、蓄積量等指標修正價值偏差。
Differentiated strategies should be adopted for different forest types such as timber forests and economic forests. Mature forests, due to their clear harvesting benefits, prioritize using the market price inversion algorithm (deducting cost profits from timber sales revenue) or the present value of harvest method; Due to the long profit cycle, young forests rely more on the reset cost method. The forest quality adjustment coefficient is a key parameter that needs to be adjusted for value deviation by integrating indicators such as tree height, breast height diameter, and volume.
2. 林地資產評估
2. Forest asset evaluation
林地使用權價值評估需考慮權屬期限與經營潛力。無限期使用權適用林地期望價法,通過無窮輪伐期凈收益折現計算永續價值;有限期使用權則采用年金資本化法,以年平均收益與投資收益率之比確定現值。立地質量與地利等級是核心變量,需通過定位觀測與成本分析量化差異。
The value assessment of forest land use rights needs to consider the ownership period and business potential. The indefinite use right is subject to the forest land expected value method, and the perpetual value is calculated by discounting the net income of the infinite rotation period; The limited term right of use is capitalized using the annuity method, and the present value is determined by the ratio of the annual average return to the investment return rate. Site quality and land use grade are core variables, and differences need to be quantified through location observation and cost analysis.
3. 森林景觀資產評估
3. Forest landscape asset evaluation
景觀資產兼具生態價值與旅游開發潛力,評估需融合主觀評價與市場比較。市場成交價比較法參考同類景區交易案例,結合景觀稀缺性、基礎設施等修正系數;剩余價值法則從綜合收益中剝離林木價值,凸顯景觀溢價。該方法要求評估人員具備生態學與經濟學跨學科知識。
Landscape assets have both ecological value and tourism development potential, and evaluation needs to integrate subjective evaluation and market comparison. The market transaction price comparison method refers to similar scenic spot transaction cases, combined with landscape scarcity, infrastructure and other correction factors; The law of surplus value extracts the value of trees from comprehensive income, highlighting the premium of landscape. This method requires evaluators to possess interdisciplinary knowledge of ecology and economics.
三、實踐中的挑戰與應對策略
3、 Challenges and coping strategies in practice
當前評估實踐面臨多重挑戰,需通過制度創新與技術升級予以破解。
The current evaluation practice faces multiple challenges that need to be addressed through institutional innovation and technological upgrading.
1. 評估獨立性保障
1. Evaluate independence guarantees
部分地區存在評估機構與行政管理部門權責不清問題,易導致價值高估或低估。對此,應推動評估主體市場化改革,建立獨立第三方機構準入機制,并通過案例復核與專家評審強化監管。
In some regions, there is a problem of unclear responsibilities between evaluation agencies and administrative management departments, which can easily lead to overvaluation or underestimation of value. In this regard, efforts should be made to promote market-oriented reforms of the evaluation subject, establish an independent third-party institution access mechanism, and strengthen supervision through case review and expert evaluation.
2. 參數獲取難度化解
2. Difficulty resolution of parameter acquisition
采伐限制、生態效益外溢性等因增加了收益預測難度。建議構建區域性森林資源數據庫,整合遙感監測、氣象數據與經營檔案,通過大數據模型模擬不同情景下的收益波動。
The restrictions on logging and the spillover of ecological benefits have increased the difficulty of predicting profits. Suggest building a regional forest resource database, integrating remote sensing monitoring, meteorological data, and management archives, and simulating revenue fluctuations under different scenarios through big data models.
3. 價值類型統一規范
3. Unified standardization of value types
抵押評估中市場價值與清算價值的選用爭議,可通過明確評估目的與風險覆蓋范圍解決。例如,信貸場景優先采用市場價值以反映正常交易價格,同時披露清算風險作為補充信息。
The dispute over the selection of market value and liquidation value in mortgage assessment can be resolved by clarifying the purpose of the assessment and the scope of risk coverage. For example, credit scenarios prioritize using market value to reflect normal transaction prices, while disclosing liquidation risk as supplementary information.
