摘　　要：以湖南省216个国有林场为例,基于2022年的森林资源调查数据,参照相关技术规范和标准进行了计算和分析。2022年湖南省国有林场森林生态系统服务功能物质量评价结果为:支持服务包括保育土壤固土33537703.03t,保肥1063578.00t,林分养分固持22144.76t;调节服务包括涵养水源调节水量255780.73万m^(3)、净化水质255780.73万m^(3),固碳释氧固碳1822771.55t、释氧4171342.57t,净化大气环境提供负离子696.99×10^(22)个、吸收气体污染物125307.85t、滞尘2191475.84t。通过对比分析可知,生态价值中的涵养水源、森林康养、生物多样性保护等功能占据主导地位。国有林场森林单位面积总价值量在空间上表现出明显差异,单位面积总价值量处于“高”等级的国有林场共有9个,“较高”等级的国有林场共有27个,“中”等级的国有林场共有107个,“较低”等级的国有林场共有69个,“低”等级的国有林场共有4个。森林生态系统服务功能监测评价为促进湖南国有林场的生态系统服务功能提升和森林资源的可持续利用提供了决策依据和参考。Taking 216 state-owned forest farms in Hunan Province as examples,based on the forest resource data in 2022,and referring to the relevant technical specifications and standards,the ecosystem service value assessment system of forest resources was constructed,calculated and analyzed.The results of the quality assessment of forest ecosystem service functions of state-owned forests in 2022 were as follows:support services included conservation of soil fixation 33537703.03 t,fertilizer preservation 1063578.00 t,forest nutrient sequestration 22144.76 t;regulating services,including the culverting water source regulating the amount of water 2.5578073 billion m^(3),purifying the water quality stagnant dust 2191475.84 t.Through comparative analysis,it could be seen that the functions of water conservation,forest recreation and biodiversity protection dominated the ecological value.The total value per unit area of forests in state-owned forest farms showd obvious differences in space,with a total of 9 state-owned forest farms in the“high”grade,27 state-owned forest farms in the“relatively high”grade,107 state-owned forest farms with“medium”grade,69 state-owned forest farms with“relatively low”grade and 4 state-owned forest farms with“low”grade.The monitoring and evaluation of forest ecosystem service function provided a basis and reference for decision-making to promote the enhancement of the ecosystem service function of state-owned forest farms in Hunan Province and the sustainable utilization of forest resources.
