森林资源作为陆地生态系统的核心组成部分,兼具生态效益、社会效益与经济效益,其资产化评估是推动生态文明建设、优化资源配置的关键环节。本文基于现行技术规范与实践需求,系统解析森林资源资产评估的核心方法及其应用场景,旨在为行业提供理论参考与实践指导。
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、评估方法体系构建
1、 Construction of Evaluation Method System
根据《森林资源资产评估技术规范(试行)》及《资产评估执业准则》,森林资源资产评估以市场法、收益法、成本法为基础,结合资源特性衍生出多元化技术路径。
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. 市场法:基于市场交易的价值发现
1. Market approach: Value discovery based on market transactions
市场法通过比对近期同类资产交易案例,经差异修正后确定评估值。其核心在于选取3个以上参照案例,通过立地质量、地利等级、物价指数等调整系数量化差异。例如,林地资源评估中,市场成交价比较法以单位面积交易价格为基准,结合立地质量调整系数(反映土壤肥力、坡度等因素)和地利等级调整系数(衡量采运成本),通过算术平均或加权模型计算评估值。该方法适用于交易活跃的区域,但要求参照物与评估对象具有高度可比性。
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:基于未来收益的现值测算
2. Income approach: calculating the present value based on future income
收益法通过预测资产未来收益并折现至评估基准日,体现资源的经济产出能力。针对林木资产,收获现值法将轮伐期内各年净收益(如木材销售收入扣除营林成本)按资本化率折现;年金资本化法则假设林地产生稳定年收益,以年平均地租与投资收益率之比计算价值。对于异龄林,周期收益资本化法需结合比例系数法或剩余价值法分割林地与林木价值。该方法要求收益预测具有可靠性,适用于成熟林或具备稳定收益预期的资源。
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:基于投入成本的价值重构
3. Cost method: value reconstruction based on input cost
成本法以重置或维持资产所需成本为基础,适用于幼龄林或特殊保护林。重置成本法通过计算各年度营林投入(含工资、物资、地租等)的现值累积,结合林分质量调整系数(反映生长状况与立地条件)确定评估值。林地费用价法则聚焦林地取得与改良成本,适用于未经营林地的初始估值。该方法强调历史成本的可追溯性,但需注意通货膨胀与折旧因素的修正。
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、评估对象的差异化应用
2、 Differentiated application of evaluation objects
森林资源资产涵盖林木、林地、森林景观等多类载体,其评估需结合资源特性选择适配方法。
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. 林木资产评估
1. Forest asset evaluation
用材林、经济林等不同林种需采用差异化策略。成熟林因具备明确采伐收益,优先采用市场价倒算法(以木材销售收入扣减成本利润)或收获现值法;幼龄林因收益周期长,更多依赖重置成本法。林分质量调整系数是关键参数,需综合树高、胸径、蓄积量等指标修正价值偏差。
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. 林地资产评估
2. Forest asset evaluation
林地使用权价值评估需考虑权属期限与经营潜力。无限期使用权适用林地期望价法,通过无穷轮伐期净收益折现计算永续价值;有限期使用权则采用年金资本化法,以年平均收益与投资收益率之比确定现值。立地质量与地利等级是核心变量,需通过定位观测与成本分析量化差异。
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. 森林景观资产评估
3. Forest landscape asset evaluation
景观资产兼具生态价值与旅游开发潜力,评估需融合主观评价与市场比较。市场成交价比较法参考同类景区交易案例,结合景观稀缺性、基础设施等修正系数;剩余价值法则从综合收益中剥离林木价值,凸显景观溢价。该方法要求评估人员具备生态学与经济学跨学科知识。
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、实践中的挑战与应对策略
3、 Challenges and coping strategies in practice
当前评估实践面临多重挑战,需通过制度创新与技术升级予以破解。
The current evaluation practice faces multiple challenges that need to be addressed through institutional innovation and technological upgrading.
1. 评估独立性保障
1. Evaluate independence guarantees
部分地区存在评估机构与行政管理部门权责不清问题,易导致价值高估或低估。对此,应推动评估主体市场化改革,建立独立第三方机构准入机制,并通过案例复核与专家评审强化监管。
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. 参数获取难度化解
2. Difficulty resolution of parameter acquisition
采伐限制、生态效益外溢性等因增加了收益预测难度。建议构建区域性森林资源数据库,整合遥感监测、气象数据与经营档案,通过大数据模型模拟不同情景下的收益波动。
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. 价值类型统一规范
3. Unified standardization of value types
抵押评估中市场价值与清算价值的选用争议,可通过明确评估目的与风险覆盖范围解决。例如,信贷场景优先采用市场价值以反映正常交易价格,同时披露清算风险作为补充信息。
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.
