在森林資產評估領域，不同林種的評估技術存在顯著差異。這些差異不僅體現在評估方法的選擇上，還涉及到數據采集、分析模型以及最終評估結果的解讀。了解這些技術差異，對于森林資產所有者、管理者以及投資者而言，是制定科學決策、優化資產配置的關鍵。

　　In the field of forest asset assessment, there are significant differences in assessment techniques for different forest species. These differences are not only reflected in the selection of evaluation methods, but also involve data collection, analysis models, and interpretation of the final evaluation results. Understanding these technological differences is crucial for forest asset owners, managers, and investors to make scientific decisions and optimize asset allocation.

　　天然林評估：三維結構解析與生物多樣性評估

　　Natural Forest Assessment: Three Dimensional Structure Analysis and Biodiversity Assessment

　　天然林作為自然演替形成的森林類型，其評估重點在于三維結構解析與生物多樣性評估。現代評估技術充分利用激光雷達（LiDAR）與多光譜遙感技術，通過高精度點云數據構建單木級模型，精確提取胸徑、樹高、冠層體積等關鍵參數。這些數據為天然林的生長狀況、健康程度以及碳匯能力提供了科學依據。

　　As a forest type formed by natural succession, the evaluation of natural forests focuses on three-dimensional structure analysis and biodiversity assessment. Modern evaluation technology fully utilizes LiDAR and multispectral remote sensing technology to construct a single tree level model through high-precision point cloud data, accurately extracting key parameters such as diameter at breast height, tree height, and canopy volume. These data provide scientific basis for the growth status, health level, and carbon sequestration capacity of natural forests.

　　同時，環境DNA（eDNA）技術的引入，使得天然林生物多樣性評估更加高效。通過無人機載采樣裝置，該技術能夠高通量監測物種組成，空間分辨率較傳統方法大幅提升。這不僅有助于了解天然林的生態價值，還為生態保護與修復提供了重要參考。

　　Meanwhile, the introduction of Environmental DNA (eDNA) technology has made the assessment of natural forest biodiversity more efficient. Through unmanned aerial sampling devices, this technology can monitor species composition with high throughput and significantly improve spatial resolution compared to traditional methods. This not only helps to understand the ecological value of natural forests, but also provides important references for ecological protection and restoration.

　　人工林評估：生長模擬與健康監測

　　Assessment of Artificial Forests: Growth Simulation and Health Monitoring

　　人工林作為人工種植的森林類型，其評估重點在于生長模擬與健康監測。地面激光掃描儀（TLS）與數字孿生技術的結合，為人工林生長模擬提供了有力支持。通過構建林分生長動態數字鏡像，該技術能夠實現每木生長量的實時預測，為人工林的經營策略制定提供了科學依據。

　　As a type of artificially planted forest, the evaluation of artificial forests focuses on growth simulation and health monitoring. The combination of ground laser scanner (TLS) and digital twin technology provides strong support for simulating the growth of artificial forests. By constructing a dynamic digital image of forest growth, this technology can achieve real-time prediction of the growth rate of each tree, providing a scientific basis for the development of management strategies for artificial forests.

　　在健康監測方面，高光譜成像技術發揮著重要作用。該技術能夠無損檢測葉面積指數（LAI）與葉綠素含量，結合物聯網傳感器網絡，構建病蟲害早期預警模型。這有助于及時發現人工林的健康問題，采取有效措施進行防治，保障人工林的健康生長。

　　Hyperspectral imaging technology plays an important role in health monitoring. This technology can non-destructive detect leaf area index (LAI) and chlorophyll content, combined with IoT sensor networks, to construct early warning models for pests and diseases. This helps to promptly identify health issues in artificial forests, take effective measures for prevention and control, and ensure the healthy growth of artificial forests.

　　混交林評估：物種識別與空間關系解析

　　Assessment of Mixed Forests: Species Identification and Spatial Relationship Analysis

　　混交林作為由多種樹種組成的森林類型，其評估重點在于物種識別與空間關系解析。多時相雷達影像與地基激光雷達數據的整合應用，為混交林評估提供了全新視角。通過該技術，能夠同步量化混交林的水平與垂直結構，揭示物種間的空間關系。

　　As a forest type composed of multiple tree species, the evaluation of mixed forests focuses on species identification and spatial relationship analysis. The integrated application of multi temporal radar images and ground-based LiDAR data provides a new perspective for the evaluation of mixed forests. Through this technology, it is possible to simultaneously quantify the horizontal and vertical structures of mixed forests and reveal the spatial relationships between species.

　　此外，量子點標記技術的應用，為混交林養分循環研究提供了新手段。通過追蹤特定元素遷移路徑，該技術能夠揭示物種間的生態互補機制，為混交林的經營與管理提供了科學依據。

　　In addition, the application of quantum dot labeling technology provides a new means for studying nutrient cycling in mixed forests. By tracking the migration pathways of specific elements, this technology can reveal the ecological complementarity mechanisms between species, providing a scientific basis for the management and management of mixed forests.

　　防護林評估：防護效能與結構健康監測

　　Assessment of Shelter Forests: Protection Efficiency and Structural Health Monitoring

　　防護林作為具有特定防護功能的森林類型，其評估重點在于防護效能與結構健康監測。合成孔徑雷達（SAR）干涉測量技術的引入，使得防護林形變監測達到了毫米級精度。結合根系生物力學模型，該技術能夠預警防護林結構穩定性風險，為防護林的安全管理提供了有力保障。

　　As a forest type with specific protective functions, the evaluation of protective forests focuses on their effectiveness and structural health monitoring. The introduction of Synthetic Aperture Radar (SAR) interferometry technology has enabled deformation monitoring of protective forests to achieve millimeter level accuracy. Combined with the root biomechanical model, this technology can warn of structural stability risks in protective forests, providing strong support for the safety management of protective forests.

　　同時，聲學監測網絡的應用，為防護林防護效能評估提供了新方法。通過分析林分對風噪的衰減特性，該技術能夠建立防護效能實時評估指標，為防護林的經營策略制定提供了科學依據。
