摘　　要：森林生态系统服务价值评估及其变化对森林生态系统的保护和管理具有重要实践意义,可为实现区域经济-社会-生态协同发展提供参考。基于遥感数据和相关测绘数据,利用生态系统服务价值(ESV)核算方法,评估1980—2020年祁连山国家级自然保护区森林生态系统服务功能并预测其变化热点。结果表明:1)祁连山国家级自然保护区森林资源丰富,森林总面积约63.66万hm^(2),森林覆盖率为14.44%。40年来总体上森林面积呈增加趋势,共增加约1.13万hm^(2),增长率约1.81%。2)自然保护区森林拥有巨大的生态系统服务价值,从时间变化看,1980—2020年ESV由454.44亿元增长到606.28亿元,增长率达33.41%,呈显著增加趋势;从不同生态系统类型的ESV贡献度看,有林地>灌木林地>疏林地>其他林地;从具体生态系统服务价值看,土壤保持>水源涵养>洪水调蓄>旅游文化服务>固碳>防风固沙>林产品生产。3)从自然保护区生态系统服务功能及价值变化热点区域预测看,调节服务的价值极易受到生态系统变化的影响,易减少的区域约占自然保护区总面积的44.21%,需要引起高度重视。供给服务和文化服务价值变化的热点区域总体上保持稳定。研究结果对祁连山国家级自然保护区森林生态系统评估提供重要的科学参考。The assessment of forest ecosystem service value and its changes is of great practical significance for the protection and management of forest ecosystems,and can provide a reference for achieving regional economic-social-ecological synergistic development.Based on remote sensing data and related mapping data,the ecosystem service value(ESV)accounting method was used to assess the forest ecosystem service function of Qilian Mountain National Nature Reserve and identify its hotspots of change from 1980 to 2020.The results show that:1)Qilian Mountain National Nature Reserve is rich in forest resources,with a total forest area of about 636600 hm^(2)and a forest coverage rate of 14.44%.Over time,the overall area has shown an increasing trend over the past 40 years,with a total increase of about 11,300 hm^(2)and a growth rate of 1.81%.2)The forests in the reserve possess great ecosystem service value,and from the perspective of time change,the ESV increased from 45444000000 Yuan to 60628000000 Yuan from 1980 to 2020,with a growth rate of 33.41%,which has shown an obvious increasing trend.From the perspective of the ESV contribution of different ecosystem types,forested land>shrubland>thin forest land>other forest land.In terms of specific ecosystem service values,soil conservation>water conservation>flood storage>tourism and cultural services>carbon sequestration>windbreaks and sand solidification>forest product production.3)Based on the prediction of hotspot areas of ecosystem service function and value change in the reserve,the value of regulating services is extremely vulnerable to the ecosystem change.The hotspot areas for the value change of provisioning services and cultural services remain stable in general,while areas prone to decrease account for 44.21%of the total protected area,which requires close attention.The results of the study provide important scientific insights for forest ecosystem assessment in Qilian Mountain National Nature Reserve.
