一、前言森林資源資產一般可以分為林木資產、林地資產、景觀資產以及野生動植物資產等幾個大類。在森林資源資產當中林木資產占比較高，并且林木資產可以派生出其他森林資源資產，所以森林資源的價值通常都是以林木資產的價值測算來加以確定。因此，對于森林資源資產的調查與評估，主要是以林木資產調查為主。

　　1、 Preface: Forest resource assets can generally be divided into several categories: forest assets, forest land assets, landscape assets, and wild animal and plant assets. Forest assets account for a relatively high proportion of forest resource assets, and can be derived from other forest resource assets, so the value of forest resources is usually determined by measuring the value of forest assets. Therefore, the investigation and evaluation of forest resource assets mainly focus on forest asset surveys.

　　四、森林資源資產現場調查核實方法森林資源資產調查核實方法主要有抽樣調查法、小班調繪法、實測法以及羅盤儀測定法，接下來著重介紹下實務工作當中最常使用的方法——抽樣調查法抽樣調查法：抽樣調查法是一種以概率論為理論基礎的調查方法。該方法主要以林分林相的特點為選取依據 ，在林區內選取具有代表性的林地區域，并以此為標準地樣本，根據一定的比例對森林資源展開抽樣調查。通過上述方法就可以根據標準低的林相、齡組、林種等特點，將整個林分的生長情況確定下來，為森林資源資產的現場調查核實提供支持。在一般情況下，森林資源資產的抽樣調查可以依據標準地的類型劃分為方形標準地、圓形標準地以及帶狀標準地，其中方形標準地是森林資源資產現場調查核實中最宜選擇的類型，但如果存在通視良好的情況，也可以采用圓形標準地。但無論選擇哪種標準地作為抽樣調查的調查樣本，都必須確保標準地面積占調查林地面積的3%至5%左右，且標準地中的林木生長情況與林地上中下坡的分布均具有代表性。抽樣調查法雖能夠靈活適用于各種類型的林地，在森林資源資產的現場調查核實中使用頻率高，但是由于標準地的選擇需要考慮調查方法、林分年齡、林分內部的一致性、工作效率等因素，導致標準地的選擇還是存在一定難度，因此很容易造成標準地代表性不足的情況出現。

　　4、 The on-site investigation and verification methods for forest resource assets mainly include sampling survey method, small group mapping method, actual measurement method, and compass measurement method. Next, we will focus on introducing the most commonly used method in practical work - sampling survey method. Sampling survey method is a survey method based on probability theory. This method mainly selects representative forest areas within the forest based on the characteristics of the forest stand, and uses them as standard samples to conduct sampling surveys of forest resources according to a certain proportion. By using the above methods, the growth status of the entire forest stand can be determined based on the characteristics of low standard forest phases, age groups, forest species, etc., providing support for on-site investigation and verification of forest resource assets. In general, the sampling survey of forest resource assets can be divided into square standard land, circular standard land, and strip standard land based on the type of standard land. Square standard land is the most suitable type for on-site investigation and verification of forest resource assets, but circular standard land can also be used if there are good visual conditions. However, regardless of which standard plot is chosen as the survey sample for the sampling survey, it is necessary to ensure that the standard plot area accounts for about 3% to 5% of the surveyed forest area, and that the growth of trees in the standard plot and the distribution of slopes in the forest are representative. Although the sampling survey method can be flexibly applied to various types of forest land and is frequently used in on-site investigation and verification of forest resource assets, the selection of standard plots still faces certain difficulties due to factors such as survey methods, stand age, consistency within the stand, and work efficiency, which can easily lead to insufficient representativeness of standard plots.

　　五、森林資源資產評估的主要方法（一）重置成本法在森林資源資產評估當中，重置成本法是實務工作中常用的方法，主要用于人工林的幼齡期價值評估。該方法是按現時的公價及生產水平重新營造一塊與被評估森林資源資產相類似的森林資源資產所需的成本費用，作為被評估森林資源資產的評估值。由于森林資源存在一定的特殊性導致對于森林資源的價值缺少明確的評估標準，因此在評估工作進行時，可以根據現實生產水平并綜合考慮面積、立地條件等多方面因素營造出基本類似或完全相同的林地。之后再根據無風險銀行利率（實務中一般考慮國債利率）、經營林木風險率和通貨膨脹率來確定折現率，并對森林資源相關的人工費用、物資費用等進行折現計算，具體公式為：該方法雖充分考慮了現實條件以及林木實際生長情況，但是其計算過程較為復雜且工作量較大，同時由于森林資源資產價值一直處于動態變化中，因此無法特別準確的評估出非幼齡期林木的價值。

　　5、 The main methods for forest resource asset assessment (1) are the reset cost method. In forest resource asset assessment, the reset cost method is a commonly used method in practical work, mainly used for the valuation of the juvenile value of artificial forests. This method involves the cost of creating a forest resource asset similar to the evaluated forest resource asset based on the current public price and production level, as the evaluation value of the evaluated forest resource asset. Due to the unique nature of forest resources, there is a lack of clear evaluation criteria for their value. Therefore, in the evaluation process, it is possible to create forest land that is basically similar or completely identical based on the actual production level and comprehensive consideration of factors such as area and site conditions. Then the discount rate is determined according to the risk-free bank interest rate (generally considering the interest rate of treasury bond in practice), the risk rate of forest management and the inflation rate, and the labor costs and material costs related to forest resources are discounted. The specific formula is: although the method fully considers the actual conditions and the actual growth of trees, the calculation process is more complex and the workload is large. At the same time, because the value of forest resources assets has been in dynamic change, it is unable to accurately evaluate the value of non young trees.

　　（二）市場價倒算法市場價倒算法較為簡單，只需計算出林木采伐銷售總收入，并減去與林木相關的采伐、銷售成本及利潤費用，即可計算出剩余收入，并以此確認為林木現實價值。該方法公式為：E=W-C-F，其中E為林木資產評估值，W表示銷售總收入，C表示木材生產經營成本（包括但不限于人工成本、采購成本、銷售費用、財務費用等），F則為木材的經營合理利潤。由于林木價格受市場因素影響較大，價格始終處于一個動態浮動中，所以使用該方法時需要對木材價格進行詳細的市場調查。同時，由于森林資源資產價值會隨著林木自身的生長而發生變化，所以使用該方法也盡量選擇成熟林或者過熟林進行評估。

　　（2） The market price inversion algorithm is relatively simple. It only needs to calculate the total revenue of forest harvesting and sales, and subtract the harvesting, sales costs, and profit expenses related to the forest to calculate the remaining revenue, which can be recognized as the actual value of the forest. The formula for this method is: E=W-C-F, where E is the assessed value of forest assets, W represents the total sales revenue, C represents the production and operation costs of wood (including but not limited to labor costs, procurement costs, sales expenses, financial expenses, etc.), and F is the reasonable profit of wood management. Due to the significant impact of market factors on forest prices, which are constantly fluctuating, a detailed market survey of timber prices is required when using this method. At the same time, as the value of forest resource assets changes with the growth of the trees themselves, it is advisable to choose mature or overripe forests for evaluation using this method.

　　（三）收益現值法通過估算被評估森里資源資產在未來經營期內各年的預期凈收益，再按照一定的折現率折算為現值，并累計求和得出被評估森林資源資產評估值。其計算公式為：收益現值法主要適用于中齡期及近熟期的林木，而幼齡期林木由于處于生長期內，距離伐木時間太長，其經濟收益很難預測，所以該方法不適用于幼齡期林木。六、結語森林資源資產評估是資產評估領域專業化分工中一塊重要的領域，其不僅僅有一般資產評估的風險性，還有其特殊性。因此在森林資源資產評估中應提高風險防范意識，選擇合理的、正確的評估方法，保障評估工作的順利開展。

　　（3） The present value of income method estimates the expected net income of the evaluated forest resource assets over the future operating period, converts it to present value at a certain discount rate, and accumulates the results to obtain the evaluated value of the forest resource assets. The calculation formula is: the present value of income method is mainly applicable to middle-aged and near mature trees, while young trees are in the growth stage and have a long distance from logging time, making it difficult to predict their economic benefits. Therefore, this method is not suitable for young trees. 6、 Conclusion: Forest resource asset evaluation is an important area of specialized division of labor in the field of asset evaluation. It not only has the risk of general asset evaluation, but also its particularity. Therefore, in the assessment of forest resource assets, risk prevention awareness should be raised, and reasonable and correct assessment methods should be selected to ensure the smooth progress of the assessment work.
