摘　　要：文章以基于第三次全国国土调查的内蒙古大青山国家级自然保护区森林资源专项调查成果数据为基础,按照《林地保护利用规划林地落界技术规程》(LY/T 1955-2022)中的林地质量等级评定方法建立评价指标体系,运用层次分析法,对古路板管理站林地质量等级进行评定,分析林地质量等级与林地类型、树种、林龄之间的关系,并提出今后的经营管理建议,以期提高保护区林地资源管理水平,科学高效保护和利用林地资源。结果表明:古路板管理站以Ⅳ级林地为主,面积为25 688.774 8 hm^(2),其次为Ⅲ级林地,面积为4 563.027 8 hm^(2),两者比重之和达到99.59%;大部分Ⅲ级林地集中在乔木林地,且Ⅲ级乔木林地主要集中在天然白桦林,其余天然林与人工林多集中在Ⅳ级林地,林地质量总体较差。This study utilizes the forest resource survey data from the Daqingshan National Nature Reserve in Inner Mongolia,derived from the third national land survey,to establish an evaluation index system based on the forest land quality grade assessment method outlined in the Technical Specification for Land Protection and Utilization Planning Forest Land Demarcation(LY/T 1955-2022).By employing the Analytic Hierarchy Process(AHP),the study evaluates the forest land quality grades at the Guluban Management Station,analyzes the relationship between forest land quality grades and factors such as forest land types,tree species,and forest ages,and offers management recommendations for future operations.The goal is to enhance the management level of forest land resources within the protected area and to protect and utilize these resources in a scientific and efficient manner.The findings indicate that the Guluban Management Station predominantly consists of Grade IV forest land,covering an area of 25688.7748 hectares,with Grade II forest land covering 4563.0278 hectares,accounting for a combined proportion of 99.59%.The majority of Grade Ⅲ forest land is concentrated in arboreal forest land,with a significant portion of Grade Ⅲ arboreal forest land being natural birch forests.The remaining natural and planted forests are mostly classified as Grade IV forest land,suggesting an overall low quality of forest land.
