　　蓄积量：蓄积量是指单位面积内森林的木材总量，是衡量森林资源经济价值的重要指标。

　　Accumulation volume: Accumulation volume refers to the total amount of timber in a forest per unit area, and is an important indicator for measuring the economic value of forest resources.

　　生物多样性：包括植物、动物和微生物的种类、数量及其分布情况，反映了森林生态系统的复杂性和稳定性。

　　Biodiversity: including the types, quantities, and distribution of plants, animals, and microorganisms, reflecting the complexity and stability of forest ecosystems.

　　2. 环境因子数据

　　2. Environmental factor data

　　森林资源的生长和分布受到多种环境因子的影响，因此环境因子数据是林木资产价格评估的重要组成部分。

　　The growth and distribution of forest resources are influenced by various environmental factors, therefore environmental factor data is an important component of forest asset price evaluation.

　　气候数据：包括温度、降水、湿度、风速等，这些因素直接影响森林的生长速度、分布范围和生态功能。

　　Climate data: including temperature, precipitation, humidity, wind speed, etc., which directly affect the growth rate, distribution range, and ecological function of forests.

　　土壤数据：土壤类型、质地、养分含量、pH值等对森林的生长和健康至关重要。土壤数据有助于评估森林的生产力和生态稳定性。

　　Soil data: Soil type, texture, nutrient content, pH value, etc. are crucial for the growth and health of forests. Soil data helps evaluate the productivity and ecological stability of forests.

　　地形数据：海拔、坡度、坡向等地形因素影响森林的分布和生长条件，是评估森林资源空间异质性的重要依据。

　　Terrain data: Terrain factors such as altitude, slope, and aspect affect the distribution and growth conditions of forests, and are important criteria for evaluating the spatial heterogeneity of forest resources.

　　水文数据：包括降水量、径流量、地下水位等，水资源的充足与否直接影响森林生态系统的健康和功能。

　　Hydrological data: including precipitation, runoff, groundwater level, etc. The adequacy of water resources directly affects the health and function of forest ecosystems.

　　3. 社会经济数据

　　3. Socio economic data

　　森林资源的评估不仅要考虑自然因素，还需结合社会经济因素，以了解森林资源的管理和利用状况。

　　The assessment of forest resources should not only consider natural factors, but also incorporate socio-economic factors to understand the management and utilization status of forest resources.

　　土地利用数据：包括森林与其他土地利用类型（如农田、草地、建设用地等）的分布和变化情况，有助于评估森林资源的竞争压力和可持续性。

　　Land use data: including the distribution and changes of forests and other land use types (such as farmland, grassland, construction land, etc.), helps to assess the competitive pressure and sustainability of forest resources.

　　人口与社区数据：包括森林周边地区的人口数量、密度、经济水平等，这些因素影响森林资源的利用方式和保护需求。

　　Population and community data: including the population size, density, economic level, etc. of the forest surrounding areas, which affect the utilization and protection needs of forest resources.

　　经济数据：包括木材、非木材林产品（如药材、食用菌等）的市场价格、需求量等，是评估森林资源经济价值的重要依据。

　　Economic data, including market prices and demand for timber and non timber forest products such as medicinal herbs and edible mushrooms, is an important basis for evaluating the economic value of forest resources.

　　政策与法规数据：包括国家和地方的森林保护政策、法律法规、管理措施等，这些因素直接影响森林资源的保护和管理效果。

　　Policy and regulatory data: including national and local forest protection policies, laws and regulations, management measures, etc. These factors directly affect the effectiveness of forest resource protection and management.

　　4. 遥感与地理信息系统（GIS）数据
