Evolution of Landscape Pattern in Taohongling Sika Deer National Nature Reserve of Jiangxi Province
By studying the landscape pattern of nature reserves and timely grasping the dynamic changes of land-scape types,it is beneficial to balance the ecological environment and development of nature reserves,protect eco-logical security,and provide important support for the formulation of management and protection plans for nature reserves.Using the Taohongling Sika Deer National Nature Reserve as the research area,ENVI,ArcGIS,and Frag-stats software platforms were used to analyze the landscape pattern and its changes in the reserve using transfer matrix and landscape pattern index methods.The results show that:① Forest landscape has an absolute advantage within the protected area,and the area is on the rise,which is conducive to improving the ecological function and biodiversity of the protected area.② Coniferous forests have gradually become the main landscape type in protec-ted areas,indicating that the ecosystem within the protected areas is tending towards stability to a certain extent.③The degree of fragmentation of small patches such as shrublands is still increasing,which may have a negative impact on the survival and reproduction of certain species.In future protected area management,efforts should be made to strengthen the protection and restoration of these fragile ecosystems.In addition,attention should be paid to the transformation between farmland landscape and coniferous forests,mixed coniferous and broad-leaved for-ests,and broad-leaved forests.Suggestion:In the process of ecological restoration and governance in protected ar-eas,the interaction and influence between landscapes should be fully considered,and monitoring and management of various landscape types should be strengthened.The landscape spatial layout within the protected area should be optimized;Ecological restoration projects should be planned reasonably based on the distribution characteris-tics of landscape types,and the coordinated development of various landscapes should be ensured.Close attention should be paid to the changes between other landscape types.Effective measures should be taken to regulate the landscape transformation and prevent the deterioration of ecological environment.Reasonable landscape ecologi-cal structure should be constructed to ensure the sustainability of ecological restoration project.Landscape type survey and monitoring should be carried out regularly to grasp the dynamic changes of landscape pattern in time and provide data support for the management and protection of protected areas.
