河南省不同区域古树资源特征分析及保护对策OA北大核心CSTPCD

[Objective]This study aiming to analyze the spatial characteristics,species composition,and quantitative characteristics of ancient tree resources in different regions of Henan Province is of great significance for protecting ancient tree resources according to local conditions.[Method]Using 9 874 scattered ancient trees in Henan Province as the research object,spatial analysis was used to ex-plore their spatial distribution characteristics.The differences in ancient tree resources among 5 regions and 6 land use types were compared and analyzed from three dimensions:quantity,species composi-tion,and tree age structure.[Result]1)The ancient tree resources in Henan Province were clustered in the northwest-southeast direction.The number of ancient trees presented a significant positive spatial correlation,while the age of ancient trees was negatively correlated.2)Funiu Mountain Area,Dabie Mountain-Tongbai Mountain Area and Taihang Mountain Area showed different advantages in terms of the number,density and species of ancient trees.The proportion of(super)aged ancient trees was relatively high in Huang-Huai-Hai Plain and Qin-Ba Mountain which had fewer ancient trees.3)In Henan Province,cultivated land,grassland,rural residential areas,forest land and other land types were the main gathering places of ancient tree resources.[Conclusion]In the three regions of Funiu Mountain Area,Dabie Mountain-Tongbai Mountain Area and Taihang Mountain Area we need to strengthen the regular patrol and inspection of ancient tree resources in remote mountain areas.In Huang-Huai-Hai Plain and Qin-Ba Mountain we should strengthen the construction of ancient tree re-serve resources while protecting the existing ancient tree resources.In the agricultural land where ancient tree resources are concentrated,we should give full play to the positive role of ancient tree re-sources in the construction of beautiful countryside and the strategy of rural revitalization.
