Evaluation of Forest Land Quality Grades at the Guluban Management Station in the Daqingshan National Nature Reserve of Inner Mongolia
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 25 688.774 8 hectares,with Grade Ⅲ forest land covering 4 563.027 8 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.
