森林資源資產(chǎn)評估是對林地、林木、森林景觀等資產(chǎn)價(jià)值的科學(xué)評定，需結(jié)合森林的生長特性、經(jīng)濟(jì)用途及生態(tài)價(jià)值，選擇適配的評估方法。不同方法適用于不同的森林類型（如用材林、經(jīng)濟(jì)林、防護(hù)林）與評估目的（如轉(zhuǎn)讓、抵押、征收補(bǔ)償），其核心是通過規(guī)范的測算流程，客觀反映森林資源的經(jīng)濟(jì)價(jià)值與生態(tài)價(jià)值，為資源開發(fā)、保護(hù)及交易提供依據(jù)。

　　Forest resource asset assessment is a scientific evaluation of the value of assets such as forest land, trees, forest landscapes, etc. It requires the selection of appropriate assessment methods based on the growth characteristics, economic use, and ecological value of the forest. Different methods are applicable to different forest types (such as timber forests, economic forests, and protective forests) and evaluation purposes (such as transfer, mortgage, and expropriation compensation). The core is to objectively reflect the economic and ecological value of forest resources through standardized calculation processes, providing a basis for resource development, protection, and trading.

　　市場法是依托市場交易數(shù)據(jù)的評估方法，適用于交易活躍的森林資源類型。該方法通過選取近期同類森林資源的交易案例（如相同林種、林齡、立地條件的林地流轉(zhuǎn)案例），對比分析案例與評估對象的差異（如地理位置、林木蓄積量、交通條件），調(diào)整交易價(jià)格后確定評估值。操作中需確保案例的可比性：用材林需對比林分質(zhì)量（如胸徑、樹高、密度）、采伐年限，經(jīng)濟(jì)林需關(guān)注品種（如油茶、核桃）、產(chǎn)量、盛產(chǎn)期剩余年限，防護(hù)林則側(cè)重生態(tài)功能指標(biāo)（如水源涵養(yǎng)能力、固碳量）。案例選取需在同一區(qū)域（如縣域范圍內(nèi)），時間間隔不超過 3 年，差異調(diào)整幅度通常不超過 30%，避免因地域差異、時間跨度大導(dǎo)致評估偏差。市場法的優(yōu)勢是直觀易懂，結(jié)果易被交易雙方接受，但在交易案例少的偏遠(yuǎn)地區(qū)或特殊林種（如珍稀樹種）評估中適用性有限。

　　The market approach is an evaluation method based on market transaction data, applicable to forest resource types with active trading. This method selects recent trading cases of similar forest resources (such as forest land transfer cases with the same forest type, age, and site conditions), compares and analyzes the differences between the cases and the evaluated objects (such as geographical location, forest volume, and transportation conditions), adjusts the trading price, and determines the evaluation value. In operation, it is necessary to ensure comparability of cases: timber forests need to compare stand quality (such as breast height diameter, tree height, density) and harvesting years, economic forests need to pay attention to varieties (such as oil tea and walnuts), yield, and remaining years of the high-yield period, and protective forests focus on ecological function indicators (such as water source nutrient capacity and carbon sequestration). The case selection should be within the same region (such as within a county), with a time interval of no more than 3 years and a difference adjustment range of usually no more than 30%, to avoid evaluation bias caused by regional differences and large time spans. The advantage of market approach is that it is intuitive and easy to understand, and the results are easily accepted by both parties in the transaction. However, its applicability is limited in remote areas with few transaction cases or in the evaluation of special forest species (such as rare tree species).

　　收益法聚焦森林資源的未來收益能力，適合有穩(wěn)定經(jīng)濟(jì)產(chǎn)出的森林資產(chǎn)。通過測算森林在經(jīng)營期內(nèi)的預(yù)期收益（如用材林的木材銷售收入、經(jīng)濟(jì)林的果實(shí)收益、森林旅游的門票收入），扣除成本（如管護(hù)費(fèi)、采伐費(fèi)、稅費(fèi)）后，按一定折現(xiàn)率折算為現(xiàn)值。關(guān)鍵參數(shù)包括：收益期（用材林按輪伐期，經(jīng)濟(jì)林按盛產(chǎn)期）、年凈收益（需參考當(dāng)?shù)亟?3 年平均產(chǎn)量與價(jià)格，如杉木的出材率、板栗的市場售價(jià)）、折現(xiàn)率（綜合考慮利率、風(fēng)險(xiǎn)因素，通常取 6%-10%）。對于用材林，需預(yù)估不同生長階段的蓄積量增長；經(jīng)濟(jì)林需考慮產(chǎn)量衰減（如盛產(chǎn)期后每年遞減 5%-10%）；公益林若有生態(tài)補(bǔ)償收入，需納入收益計(jì)算。收益法的難點(diǎn)在于收益預(yù)測的準(zhǔn)確性，需避免過度樂觀估計(jì)產(chǎn)量或忽視自然災(zāi)害（如病蟲害、火災(zāi)）的風(fēng)險(xiǎn)，折現(xiàn)率的微小變動也會對結(jié)果產(chǎn)生較大影響，需結(jié)合行業(yè)平均水平謹(jǐn)慎確定。

　　The income approach focuses on the future profitability of forest resources and is suitable for forest assets with stable economic output. By calculating the expected revenue of forests during the management period (such as timber sales revenue from timber forests, fruit revenue from economic forests, and ticket revenue from forest tourism), deducting costs (such as management fees, logging fees, taxes and fees), it is converted to present value at a certain discount rate. The key parameters include: yield period (timber forest according to the rotation period, economic forest according to the peak production period), annual net yield (referring to the local average yield and price in the past three years, such as the yield rate of Chinese fir and the market price of chestnuts), discount rate (considering interest rates and risk factors comprehensively, usually taking 6% -10%). For timber forests, it is necessary to estimate the accumulation growth at different growth stages; Economic forests need to consider yield decline (such as an annual decrease of 5% -10% after the peak production period); If there is ecological compensation income from public welfare forests, it needs to be included in the income calculation. The difficulty of the income approach lies in the accuracy of income forecasting, which requires avoiding overly optimistic estimates of production or ignoring the risks of natural disasters such as pests and fires. Even small changes in the discount rate can have a significant impact on the results, and should be carefully determined in conjunction with the industry average.

　　成本法以森林資源的重置成本為基礎(chǔ)，適用于幼齡林、人工造林及苗圃地評估。計(jì)算方式為：重置成本（如造林費(fèi)、撫育費(fèi)、管護(hù)費(fèi)的累計(jì)投入，按當(dāng)前物價(jià)水平調(diào)整）扣除損耗（如因病蟲害、管理不善導(dǎo)致的生長量不足）。幼齡林因尚無收益，成本法是主要評估方式，需詳細(xì)核算造林環(huán)節(jié)的各項(xiàng)支出（如苗木費(fèi)、整地費(fèi)、灌溉費(fèi)），并按資金時間價(jià)值計(jì)算利息（年利率取同期貸款利率）。苗圃地評估需包含土地平整費(fèi)、基礎(chǔ)設(shè)施（如灌溉系統(tǒng)）建設(shè)費(fèi)、苗木培育成本，損耗按苗木成活率（如成活率 90% 以下需按比例扣減）計(jì)算。成本法的局限是未充分考慮森林的未來收益與市場價(jià)值，不適用于成熟林評估，且對歷史成本記錄不完整的林地（如天然林）難以準(zhǔn)確測算。

　　The cost method is based on the replacement cost of forest resources and is suitable for evaluating young forests, artificial afforestation, and nursery land. The calculation method is: reset cost (such as the cumulative investment of afforestation fees, nurturing fees, and management fees, adjusted according to the current price level) minus losses (such as insufficient growth caused by pests, diseases, and poor management). Due to the lack of income from young forests, the cost method is the main evaluation method, which requires detailed accounting of various expenses in the afforestation process (such as seedling fees, land preparation fees, irrigation fees), and calculating interest based on the time value of funds (annual interest rate taken from the same period loan interest rate). The evaluation of nursery land should include land leveling fees, infrastructure (such as irrigation systems) construction fees, and seedling cultivation costs. Losses should be calculated based on the survival rate of seedlings (if the survival rate is below 90%, it should be deducted proportionally). The limitation of the cost method is that it does not fully consider the future benefits and market value of forests, is not suitable for mature forest assessment, and is difficult to accurately calculate for forests with incomplete historical cost records (such as natural forests).

　　林地資產(chǎn)評估需單獨(dú)考量，常結(jié)合土地特性選擇方法。林地作為森林資源的載體，其價(jià)值受區(qū)位（如距城鎮(zhèn)距離、交通便利性）、立地質(zhì)量（如土壤肥力、坡度、海拔）、用途限制（如生態(tài)保護(hù)紅線、采伐限額）影響。評估可采用市場法（對比同類林地流轉(zhuǎn)價(jià)）、收益法（按林地租金或承包費(fèi)折現(xiàn)）或基準(zhǔn)地價(jià)修正法（以當(dāng)?shù)亓值鼗鶞?zhǔn)地價(jià)為基礎(chǔ)，按容積率、地利等級修正）。生態(tài)公益林的林地評估需納入生態(tài)補(bǔ)償收益，經(jīng)濟(jì)林林地需考慮土壤改良投入對產(chǎn)量的提升作用，采伐跡地需扣除更新造林成本。林地使用權(quán)年限（通常為 30-70 年）也會影響價(jià)值，剩余年限短的林地需按比例折減。

　　The evaluation of forest land assets needs to be considered separately and often combined with the selection method based on land characteristics. As a carrier of forest resources, the value of forest land is influenced by location (such as distance from urban areas, transportation convenience), site quality (such as soil fertility, slope, altitude), and usage restrictions (such as ecological protection red lines, logging quotas). The evaluation can be conducted using the market method (comparing the transfer prices of similar forest land), income method (discounting forest land rent or contract fees), or benchmark land price correction method (based on the local forest land benchmark land price, adjusted according to plot ratio and land use grade). The evaluation of ecological public welfare forests should include ecological compensation income, economic forest land should consider the effect of soil improvement investment on yield increase, and the cost of reforestation should be deducted from the harvested land. The tenure of forest land use rights (usually 30-70 years) also affects its value, and forest land with shorter remaining tenure needs to be reduced proportionally.

　　特殊森林資源評估需采用針對性方法，兼顧經(jīng)濟(jì)與生態(tài)價(jià)值。古樹名木、珍稀樹種評估，除考慮其觀賞價(jià)值、科研價(jià)值外，需參考保護(hù)級別（如國家一級、二級），采用專家打分法結(jié)合市場法（如同類移植案例），禁止單純按木材價(jià)值評估。森林景觀資產(chǎn)（如森林公園）評估需結(jié)合旅游收入、景觀質(zhì)量（如景觀多樣性、可達(dá)性），采用收益法與假設(shè)開發(fā)法（如未來景區(qū)升級后的收益增量）。評估過程中需遵守生態(tài)保護(hù)法規(guī)，對禁止采伐、限制開發(fā)的森林資源，不得按商業(yè)開發(fā)價(jià)值評估，確保評估結(jié)果符合可持續(xù)發(fā)展要求。

　　The assessment of special forest resources requires targeted methods that take into account both economic and ecological values. The evaluation of ancient and rare tree species should not only consider their ornamental value and scientific research value, but also refer to the protection level (such as national level one or two), and use expert scoring method combined with market method (such as similar transplant cases). It is prohibited to evaluate solely based on the value of the wood. The evaluation of forest landscape assets (such as forest parks) should be based on tourism revenue and landscape quality (such as landscape diversity and accessibility), using the income approach and hypothetical development approach (such as the incremental income after future scenic area upgrades). During the evaluation process, it is necessary to comply with ecological protection regulations. Forest resources that are prohibited from logging or restricted from development shall not be evaluated based on their commercial development value to ensure that the evaluation results meet the requirements of sustainable development.
