在森林資產(chǎn)評估領(lǐng)域，不同林種的評估技術(shù)存在顯著差異。這些差異不僅體現(xiàn)在評估方法的選擇上，還涉及到數(shù)據(jù)采集、分析模型以及最終評估結(jié)果的解讀。了解這些技術(shù)差異，對于森林資產(chǎn)所有者、管理者以及投資者而言，是制定科學(xué)決策、優(yōu)化資產(chǎn)配置的關(guān)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(jié)構(gòu)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(jié)構(gòu)解析與生物多樣性評估。現(xiàn)代評估技術(shù)充分利用激光雷達(dá)（LiDAR）與多光譜遙感技術(shù)，通過高精度點云數(shù)據(jù)構(gòu)建單木級模型，精確提取胸徑、樹高、冠層體積等關(guān)鍵參數(shù)。這些數(shù)據(jù)為天然林的生長狀況、健康程度以及碳匯能力提供了科學(xué)依據(jù)。

　　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(huán)境DNA（eDNA）技術(shù)的引入，使得天然林生物多樣性評估更加高效。通過無人機(jī)載采樣裝置，該技術(shù)能夠高通量監(jiān)測物種組成，空間分辨率較傳統(tǒng)方法大幅提升。這不僅有助于了解天然林的生態(tài)價值，還為生態(tài)保護(hù)與修復(fù)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.

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(jiān)測方面，高光譜成像技術(shù)發(fā)揮著重要作用。該技術(shù)能夠無損檢測葉面積指數(shù)（LAI）與葉綠素含量，結(jié)合物聯(lián)網(wǎng)傳感器網(wǎng)絡(luò)，構(gòu)建病蟲害早期預(yù)警模型。這有助于及時發(fā)現(xiàn)人工林的健康問題，采取有效措施進(jìn)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(guān)系解析。多時相雷達(dá)影像與地基激光雷達(dá)數(shù)據(jù)的整合應(yīng)用，為混交林評估提供了全新視角。通過該技術(shù)，能夠同步量化混交林的水平與垂直結(jié)構(gòu)，揭示物種間的空間關(guān)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(biāo)記技術(shù)的應(yīng)用，為混交林養(yǎng)分循環(huán)研究提供了新手段。通過追蹤特定元素遷移路徑，該技術(shù)能夠揭示物種間的生態(tài)互補(bǔ)機(jī)制，為混交林的經(jīng)營與管理提供了科學(xué)依據(jù)。
