摘　　要：呼伦湖自然保护区生态意义重大,对维系中国北方生态安全起着重要的作用。基于1976-2021年间的5期遥感影像数据,运用生态服务价值当量因子法估算呼伦湖自然保护区的土地生态系统服务价值变化。结果表明:1976-2021年期间未利用地增加明显,林地与耕地次之,水域显著减少,草地和湿地表现出波动变化;1976-2021年期间土地生态系统价值总体呈现下降趋势(减少率为7.9%),其中未利用地、林地及耕地生态服务价值持续增加,而水域和湿地则呈现显著减少;单项土地生态系统服务价值除土壤形成与保护、原材料和气体调节略有增加外,其它类型均有不同程度的减少。The ecological protection of Hulun LakeNationalNature Reserve is of great significance and plays an important role in maintaining ecological security in the north of China.Taking Dalai Lake National Nature Reserve as the research object,based on 5 remote sensing image data from 1976 to 2021,supported by ArcGIS software,the ecosystem service value of the land ecosystem in the reserve is estimated using the ecological service value equivalent factor method.The finding show that:the area of woodland and arable land in Hulun Lake National Nature Reserve continued to increase from 1976 to 2021,the unused land increased significantly,the water area decreased significantly,and the grassland and wetland showed an increase-decrease-increased-decrease trend;the total value of the land ecosystem in Hulun Lake National Nature Reserve showed a downward trend,with a reduction rate of 7.9%from 1976 to 2021.The ecosystem service value of cultivated land,woodland,and unused land continued to increase,while waters and wetlands showed a significant decrease;in addition to the slight increase in the value of raw materials and soil formation and protection of the land ecosystem,the value of other ecosystem services have different degrees of reduction;the reduction of water area and wetland area reduces the value of water conservation,which drives the total value of land ecosystem services to decrease;the ecological function is always the main function of Hulun Lake National Nature Reserve.
