森林資源資產(chǎn)評(píng)估是自然資源管理領(lǐng)域的重要環(huán)節(jié),其核心價(jià)值在于將生態(tài)資源轉(zhuǎn)化為可量化、可交易的經(jīng)濟(jì)價(jià)值,為生態(tài)保護(hù)與可持續(xù)發(fā)展提供科學(xué)依據(jù)。這項(xiàng)工作不僅涉及林業(yè)經(jīng)濟(jì)領(lǐng)域,更與生態(tài)保護(hù)、碳匯交易、產(chǎn)權(quán)流轉(zhuǎn)等現(xiàn)代生態(tài)經(jīng)濟(jì)活動(dòng)密切相關(guān)。
Forest resource asset assessment is an important part of natural resource management, and its core value lies in transforming ecological resources into quantifiable and tradable economic value, providing scientific basis for ecological protection and sustainable development. This work not only involves the field of forestry economy, but is also closely related to modern ecological economic activities such as ecological protection, carbon trading, and property rights transfer.
評(píng)估工作的首要任務(wù)是明確評(píng)估對(duì)象與范圍。森林資源資產(chǎn)包含林木、林地、林下經(jīng)濟(jì)作物及生態(tài)服務(wù)功能等多個(gè)維度。評(píng)估時(shí)需區(qū)分用材林、經(jīng)濟(jì)林、防護(hù)林等不同林種,因其經(jīng)濟(jì)價(jià)值實(shí)現(xiàn)方式存在顯著差異。例如用材林側(cè)重木材蓄積量與生長(zhǎng)周期,經(jīng)濟(jì)林則關(guān)注果實(shí)產(chǎn)量與市場(chǎng)價(jià)格波動(dòng),而防護(hù)林的生態(tài)價(jià)值評(píng)估需引入碳匯計(jì)量等創(chuàng)新方法。
The primary task of evaluation work is to clarify the evaluation object and scope. Forest resource assets include multiple dimensions such as trees, forest land, understory economic crops, and ecological service functions. When evaluating, it is necessary to distinguish between different forest types such as timber forests, economic forests, and protective forests, as their economic value realization methods have significant differences. For example, timber forests focus on timber volume and growth cycle, while economic forests focus on fruit yield and market price fluctuations. The ecological value assessment of protective forests requires the introduction of innovative methods such as carbon sequestration measurement.
數(shù)據(jù)采集是評(píng)估的基礎(chǔ)環(huán)節(jié)。專業(yè)團(tuán)隊(duì)需通過(guò)現(xiàn)場(chǎng)勘查獲取胸徑、樹高、株數(shù)等實(shí)測(cè)數(shù)據(jù),結(jié)合遙感影像解析林分結(jié)構(gòu)與空間分布。同時(shí)需收集近三年的木材市場(chǎng)行情、當(dāng)?shù)亓謽I(yè)政策、災(zāi)害發(fā)生頻率等動(dòng)態(tài)信息。值得注意的是,生物多樣性價(jià)值等非市場(chǎng)價(jià)值需借助替代成本法或條件價(jià)值法進(jìn)行估算,這對(duì)評(píng)估人員的跨學(xué)科知識(shí)儲(chǔ)備提出較高要求。
Data collection is the fundamental step in evaluation. A professional team needs to obtain measured data such as breast height diameter, tree height, and number of trees through on-site investigation, and combine remote sensing images to analyze forest structure and spatial distribution. At the same time, it is necessary to collect dynamic information on the timber market situation, local forestry policies, and frequency of disasters in the past three years. It is worth noting that non market values such as biodiversity value need to be estimated using alternative cost methods or contingent valuation methods, which requires a high level of interdisciplinary knowledge reserves from evaluators.
在評(píng)估方法選擇上,市場(chǎng)比較法適用于具有活躍交易市場(chǎng)的商品林資源,通過(guò)比對(duì)近期同類資產(chǎn)交易案例確定價(jià)值。收益現(xiàn)值法更適用于經(jīng)濟(jì)林或碳匯項(xiàng)目,需構(gòu)建包含采伐收益、生態(tài)補(bǔ)償、碳交易收入的現(xiàn)金流模型。成本法多用于幼齡林或生態(tài)公益林評(píng)估,通過(guò)計(jì)算培育成本與合理利潤(rùn)確定基準(zhǔn)價(jià)值。實(shí)際應(yīng)用中常采用兩種以上方法交叉驗(yàn)證,以提高評(píng)估結(jié)果的公信力。
In terms of evaluation method selection, the market comparison method is applicable to commodity forest resources with active trading markets, and the value is determined by comparing recent similar asset trading cases. The present value of earnings method is more suitable for economic forests or carbon sequestration projects, and requires the construction of a cash flow model that includes logging income, ecological compensation, and carbon trading revenue. The cost method is often used for evaluating young forests or ecological public welfare forests, determining the benchmark value by calculating the cultivation cost and reasonable profit. In practical applications, two or more methods are often used for cross validation to improve the credibility of the evaluation results.
特殊價(jià)值要素的量化是評(píng)估中的技術(shù)難點(diǎn)。森林的固碳能力需依據(jù)IPCC碳計(jì)量指南,結(jié)合樹種特性與林齡結(jié)構(gòu)進(jìn)行測(cè)算;水土保持功能需運(yùn)用水文模型評(píng)估涵養(yǎng)水源價(jià)值;景觀美學(xué)價(jià)值則需結(jié)合旅游市場(chǎng)數(shù)據(jù)與游客支付意愿分析。這些生態(tài)服務(wù)功能的貨幣化轉(zhuǎn)換,需要評(píng)估機(jī)構(gòu)與生態(tài)學(xué)、環(huán)境經(jīng)濟(jì)學(xué)專家深度協(xié)作。
The quantification of special value elements is a technical challenge in evaluation. The carbon sequestration capacity of forests needs to be calculated based on the IPCC carbon measurement guidelines, combined with tree species characteristics and forest age structure; The function of soil and water conservation requires the use of hydrological models to evaluate the value of conserving water sources; The aesthetic value of landscape needs to be analyzed in conjunction with tourism market data and tourists' willingness to pay. The monetization of these ecological service functions requires deep collaboration between evaluation institutions and experts in ecology and environmental economics.
評(píng)估報(bào)告應(yīng)包含資源現(xiàn)狀描述、評(píng)估方法說(shuō)明、參數(shù)取值依據(jù)、價(jià)值測(cè)算過(guò)程及風(fēng)險(xiǎn)提示等內(nèi)容。特別需要關(guān)注法律權(quán)屬核查,確保評(píng)估對(duì)象不存在權(quán)屬糾紛或非法占用情形。對(duì)于涉及集體林權(quán)的項(xiàng)目,還需審查流轉(zhuǎn)程序是否符合《農(nóng)村土地承包法》相關(guān)規(guī)定。
The evaluation report should include a description of the current status of resources, an explanation of the evaluation methods, the basis for parameter values, the process of value estimation, and risk warnings. Special attention should be paid to legal ownership verification to ensure that there are no ownership disputes or illegal occupation of the evaluated object. For projects involving collective forest rights, it is necessary to review whether the transfer procedures comply with the relevant provisions of the Rural Land Contracting Law.
在實(shí)踐應(yīng)用中,評(píng)估結(jié)果常服務(wù)于產(chǎn)權(quán)交易、抵押融資、損害賠償、生態(tài)補(bǔ)償?shù)葓?chǎng)景。例如林權(quán)抵押貸款評(píng)估需兼顧資產(chǎn)現(xiàn)值與風(fēng)險(xiǎn)緩釋措施,森林生態(tài)損害賠償評(píng)估則要區(qū)分直接損失與間接生態(tài)服務(wù)功能損失。隨著碳匯交易市場(chǎng)的完善,森林資源評(píng)估正在向"生態(tài)產(chǎn)品價(jià)值實(shí)現(xiàn)"方向深化拓展。
In practical applications, evaluation results often serve scenarios such as property rights transactions, mortgage financing, damage compensation, and ecological compensation. For example, the evaluation of forest tenure mortgage loans needs to take into account both the present value of assets and risk mitigation measures, while the evaluation of forest ecological damage compensation needs to distinguish between direct losses and indirect ecological service function losses. With the improvement of the carbon trading market, forest resource assessment is deepening and expanding towards the realization of ecological product value.
當(dāng)前評(píng)估領(lǐng)域正面臨方法論創(chuàng)新挑戰(zhàn)。傳統(tǒng)評(píng)估體系側(cè)重經(jīng)濟(jì)價(jià)值核算,而新時(shí)代要求建立包含生物多樣性、氣候調(diào)節(jié)等多元價(jià)值的綜合評(píng)估框架。這需要評(píng)估機(jī)構(gòu)持續(xù)更新技術(shù)標(biāo)準(zhǔn),加強(qiáng)大數(shù)據(jù)與人工智能技術(shù)應(yīng)用,提升復(fù)雜生態(tài)系統(tǒng)的價(jià)值解構(gòu)能力,最終構(gòu)建起符合生態(tài)文明要求的現(xiàn)代化森林資源評(píng)估體系。
The current evaluation field is facing methodological innovation challenges. The traditional evaluation system focuses on economic value accounting, while the new era requires the establishment of a comprehensive evaluation framework that includes multiple values such as biodiversity and climate regulation. This requires evaluation institutions to continuously update technical standards, strengthen the application of big data and artificial intelligence technology, enhance the ability to deconstruct the value of complex ecosystems, and ultimately build a modern forest resource assessment system that meets the requirements of ecological civilization.
