自然資源資產綜合評估是生態文明建設的重要技術支撐，其核心在于通過系統化、定量化的評價手段，厘清自然資源資產的存量、質量及價值流動規律，為國土空間規劃、生態補償機制設計及自然資源資產離任審計提供科學依據。

　　The comprehensive evaluation of natural resource assets is an important technical support for the construction of ecological civilization. Its core lies in clarifying the stock, quality, and value flow laws of natural resource assets through systematic and quantitative evaluation methods, providing scientific basis for national spatial planning, ecological compensation mechanism design, and natural resource asset exit audit.

　　評估對象呈現多維度特征。從資源類型看，涵蓋土地、礦產、森林、水、濕地、海洋等全要素資源，需根據資源特性構建差異化指標。例如，耕地資源需重點評估土壤有機質含量、耕作層厚度等生產性能指標；森林資源則需關注胸徑、樹高、蓄積量等生長參數。從資產屬性看，需區分經營性資產與非經營性資產，前者如探明儲量的礦產資源，后者如具有生態服務功能的水源涵養區。

　　The evaluation object presents multidimensional features. From the perspective of resource types, covering all factor resources such as land, minerals, forests, water, wetlands, and oceans, differentiated indicators need to be constructed based on resource characteristics. For example, farmland resources need to focus on evaluating production performance indicators such as soil organic matter content and tillage layer thickness; Forest resources need to pay attention to growth parameters such as breast height diameter, tree height, and stock volume. From the perspective of asset attributes, it is necessary to distinguish between operational assets and non operational assets. The former, such as mineral resources with proven reserves, and the latter, such as water conservation areas with ecological service functions.

　　價值核算體系是評估核心。需建立“三重價值”核算框架：經濟價值通過市場法、收益法等工具量化，如采用影子價格法評估水資源經濟產出；生態價值運用生態系統生產總值（GEP）核算體系，將固碳釋氧、水土保持等生態服務轉化為貨幣價值；社會價值則通過條件價值法評估公眾支付意愿，如濕地公園的文化游憩價值。某流域綜合評估案例顯示，其GEP總值達到GDP的1.8倍，凸顯生態資產的經濟外溢性。

　　The value accounting system is the core of evaluation. It is necessary to establish a "triple value" accounting framework: economic value is quantified through tools such as market method and income method, such as using shadow price method to evaluate the economic output of water resources; The ecological value utilizes the Gross Ecosystem Production (GEP) accounting system to convert ecological services such as carbon sequestration, oxygen release, and soil and water conservation into monetary value; Social value is evaluated through the contingent valuation method to assess public willingness to pay, such as the cultural and recreational value of wetland parks. A comprehensive assessment case of a certain watershed shows that its total GEP value has reached 1.8 times the GDP, highlighting the economic spillover of ecological assets.

　　空間異質性評估是技術難點。需采用網格化評估方法，將評估區域劃分為1公里×1公里的評估單元，集成遙感監測、地面觀測等多源數據。對于青藏高原等生態脆弱區，需建立凍土活動層厚度、植被凈初級生產力等特色指標；在長三角城市群，則需重點評估建設用地擴張對耕地資源的占用效應。某區域實踐表明，網格化評估使資源時空分布精度提升。

　　The assessment of spatial heterogeneity is a technical challenge. Grid based evaluation method should be adopted to divide the evaluation area into assessment units of 1 kilometer by 1 kilometer, integrating multi-source data such as remote sensing monitoring and ground observation. For ecologically fragile areas such as the Qinghai Tibet Plateau, it is necessary to establish characteristic indicators such as the thickness of permafrost activity layer and net primary productivity of vegetation; In the Yangtze River Delta urban agglomeration, it is necessary to focus on evaluating the occupation effect of construction land expansion on arable land resources. Practice in a certain region has shown that grid based evaluation improves the accuracy of resource spatiotemporal distribution.

　　動態監測機制是評估保障。需構建“天-空-地-網”一體化監測網絡，通過衛星遙感實現季度級宏觀監測，無人機航測完成月度中觀核查，地面傳感器網絡進行實時微觀感知。對于稀土等戰略性礦產，需部署激光誘導擊穿光譜（LIBS）技術實現原位快速檢測。某智慧監測平臺已實現90%以上評估數據的自動化采集，更新周期縮短。

　　The dynamic monitoring mechanism is an evaluation guarantee. It is necessary to build an integrated monitoring network of "sky air ground network", achieve quarterly macro monitoring through satellite remote sensing, complete monthly meso level verification through unmanned aerial vehicle aerial survey, and conduct real-time micro perception through ground sensor network. For strategic minerals such as rare earths, laser-induced breakdown spectroscopy (LIBS) technology needs to be deployed to achieve rapid in-situ detection. A certain smart monitoring platform has achieved automated collection of over 90% of evaluation data and shortened update cycles.

　　不確定性管理是評估關鍵。需建立誤差溯源模型，識別數據采集、模型假設等環節的不確定性來源。對于碳匯量核算，需通過蒙特卡洛模擬量化參數敏感性，將結果置信區間控制在±15%以內。在資源價值折現率選擇上，需構建無風險利率、風險溢價雙因子模型，避免主觀判斷偏差。

　　Uncertainty management is key to evaluation. An error traceability model needs to be established to identify sources of uncertainty in data collection, model assumptions, and other processes. For carbon sequestration accounting, it is necessary to quantify parameter sensitivity through Monte Carlo simulation and control the confidence interval of the results within ± 15%. In selecting the discount rate for resource value, it is necessary to construct a two factor model of risk-free interest rate and risk premium to avoid subjective judgment bias.

　　成果應用呈現多場景特征。在國土空間規劃中，評估結果可支撐“三區三線”劃定，某城市實踐表明，依據資源承載力評估調整用地布局后，生態紅線沖突率下降。在生態補償方面，需建立“受益者付費、保護者受償”的橫向補償機制，某流域上下游補償標準即以水質改善量、森林蓄積量增量為核心參數。

　　The application of achievements presents multi scenario characteristics. In the national spatial planning, the evaluation results can support the delineation of the "three zones and three lines". The practice of a certain city has shown that after adjusting the land layout based on the assessment of resource carrying capacity, the conflict rate of ecological red lines has decreased. In terms of ecological compensation, it is necessary to establish a horizontal compensation mechanism of "beneficiaries pay, protectors are compensated". The compensation standards for upstream and downstream of a certain watershed are based on the core parameters of water quality improvement and forest accumulation increment.

　　隨著數字孿生技術的發展，自然資源資產評估正邁向智能化階段。通過構建三維實景模型，實現資產變化的可視化推演；利用區塊鏈技術確保評估數據的不可篡改性。某新型平臺已實現評估流程的自動化與評估報告的智能生成，工作效率提升。未來，人工智能將深度融入評估體系，通過機器學習持續優化核算模型，推動自然資源資產管理向精準化、智慧化方向演進。

　　With the development of digital twin technology, natural resource asset evaluation is moving towards an intelligent stage. By constructing a three-dimensional real-life model, the visualization and deduction of asset changes can be achieved; Using blockchain technology to ensure the immutability of evaluation data. A new platform has achieved automation of the evaluation process and intelligent generation of evaluation reports, improving work efficiency. In the future, artificial intelligence will be deeply integrated into the evaluation system, continuously optimizing accounting models through machine learning, and promoting the evolution of natural resource asset management towards precision and intelligence.
