老头山自然保护区乔木林资源现状分析及发展建议OA

Based on historical forest and grassland resource survey data,this study integrates GF-1 satellite imagery(with a spatial resolution better than 2 m)with the Third National Land Survey.By employing UAV aerial surveys,por-table digital assistants(PDA),and seven types of forestry-specific tables(including Single-tree Volume Table,Site Type Table,Vegetation Type Table,etc.),a comprehensive survey was conducted at the forest compartment level to obtain key parameters of arbor forest resources in the protected area.These parameters encompass forestland area,species composi-tion,dominant tree species,age groups,canopy density,diameter classes,and origin of stands.Based on the survey results,the distribution patterns of these factors were analyzed.Considering the characteristics and current challenges of arbor forest resources in the protected area,corresponding conservation and development recommendations were proposed.
