自然资源资产综合评估是生态文明建设的重要技术支撑，其核心在于通过系统化、定量化的评价手段，厘清自然资源资产的存量、质量及价值流动规律，为国土空间规划、生态补偿机制设计及自然资源资产离任审计提供科学依据。

　　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.

　　评估对象呈现多维度特征。从资源类型看，涵盖土地、矿产、森林、水、湿地、海洋等全要素资源，需根据资源特性构建差异化指标。例如，耕地资源需重点评估土壤有机质含量、耕作层厚度等生产性能指标；森林资源则需关注胸径、树高、蓄积量等生长参数。从资产属性看，需区分经营性资产与非经营性资产，前者如探明储量的矿产资源，后者如具有生态服务功能的水源涵养区。

　　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.

　　价值核算体系是评估核心。需建立“三重价值”核算框架：经济价值通过市场法、收益法等工具量化，如采用影子价格法评估水资源经济产出；生态价值运用生态系统生产总值（GEP）核算体系，将固碳释氧、水土保持等生态服务转化为货币价值；社会价值则通过条件价值法评估公众支付意愿，如湿地公园的文化游憩价值。某流域综合评估案例显示，其GEP总值达到GDP的1.8倍，凸显生态资产的经济外溢性。

　　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.

　　空间异质性评估是技术难点。需采用网格化评估方法，将评估区域划分为1公里×1公里的评估单元，集成遥感监测、地面观测等多源数据。对于青藏高原等生态脆弱区，需建立冻土活动层厚度、植被净初级生产力等特色指标；在长三角城市群，则需重点评估建设用地扩张对耕地资源的占用效应。某区域实践表明，网格化评估使资源时空分布精度提升。

　　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.

　　动态监测机制是评估保障。需构建“天-空-地-网”一体化监测网络，通过卫星遥感实现季度级宏观监测，无人机航测完成月度中观核查，地面传感器网络进行实时微观感知。对于稀土等战略性矿产，需部署激光诱导击穿光谱（LIBS）技术实现原位快速检测。某智慧监测平台已实现90%以上评估数据的自动化采集，更新周期缩短。

　　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.

　　不确定性管理是评估关键。需建立误差溯源模型，识别数据采集、模型假设等环节的不确定性来源。对于碳汇量核算，需通过蒙特卡洛模拟量化参数敏感性，将结果置信区间控制在±15%以内。在资源价值折现率选择上，需构建无风险利率、风险溢价双因子模型，避免主观判断偏差。

　　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.

　　成果应用呈现多场景特征。在国土空间规划中，评估结果可支撑“三区三线”划定，某城市实践表明，依据资源承载力评估调整用地布局后，生态红线冲突率下降。在生态补偿方面，需建立“受益者付费、保护者受偿”的横向补偿机制，某流域上下游补偿标准即以水质改善量、森林蓄积量增量为核心参数。

　　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.

　　随着数字孪生技术的发展，自然资源资产评估正迈向智能化阶段。通过构建三维实景模型，实现资产变化的可视化推演；利用区块链技术确保评估数据的不可篡改性。某新型平台已实现评估流程的自动化与评估报告的智能生成，工作效率提升。未来，人工智能将深度融入评估体系，通过机器学习持续优化核算模型，推动自然资源资产管理向精准化、智慧化方向演进。

　　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.
