| Forest vegetation is a significant landscape resource in scenic spots,which has inestimable economic,social and ecological value.But if we put too much emphasis on the protection of scenic spots without human intervention or maintenance management,or if complete natural competition and succession of plant communities are allowed,it may lead to problems such as single tree species and monotonous seasonal changes,especially for scenic spots with a large area of artificial forests.Therefore,it is very necessary to research the upgrading and transformation planning of forest vegetation landscape.This study analyzes the relevant domestic and foreign theoretical and practical achievements,using Arc GIS technology and Analytic Hierarchy Process.In addition,the forest vegetation upgrading and transformation of the Zipeng Mountain Scenic Spot was explored.Based on these,this paper puts forward strategies and methods for the upgrading and reconstruction of forest vegetation landscape in scenic spots.The main results are as follows:(1)To provide references,this paper summarizes the modern forest management theory and sorts out the management history of China’s forests since the founding of the People’s Republic of China.Then,the research status is reviewed from the aspects of upgrading methods,plant selection,changes and impacts before and after upgrading,landscape evaluation,and application of new technologies.(2)Through on-the-spot investigation,the present situation of forest vegetation in Zipeng was found out.Then,the indicators such as forest vegetation type,community composition,structural characteristics,and growth status were analyzed.Meanwhile,the succession of the main plant communities was predicted,which laid a great foundation.(3)Combined with the AHP and the landscape comprehensive index method,this paper constructs an evaluation system,selecting 11 evaluation indicators from three levels of landscape value,ecological value,and functional value.According to the system,the current forest vegetation landscape of Zipeng Mountain is evaluated.According to the analysis results of vegetation status and landscape evaluation,the existing problems of forest vegetation in the Zipeng Mountain Scenic Area are sorted out.(4)Based on the current vegetation and the problems,combined with the upper-level planning,this paper establishes landscape upgrading and reconstruction structure from "one axis,one ring,three points,and seven districts".Then the transformation measures are made from five aspects: conservation,tending,tending renewal,regeneration,and ecological restoration,to gradually improve the forest vegetation landscape quality.(5)Given the above research theories and practical case studies,this paper proposes strategies for forest vegetation improvement and transformation planning,including five aspects: guiding ideology and principles,planning paths and methods,planning divisions and layouts,planning modes,and specific improvement and transformation measures.It is hoped that the multiple benefits of the forest can be fully utilized and provide a reference for the improvement and transformation of the forest vegetation in the scenic area. |
