Plant Landscape Restoration In Shenyang National Forest Park

Forest is the main body of the earth's ecology and has an irreplaceable role.With the development of the times," return to nature,return to nature " has become a reality in people's desire and pursuit.Therefore,scientific and reasonable forest park vegetation landscape planning is not only of great significance to the protection of resources,but also has more economic benefits and educational value.In this paper,for Shenyang National Forest Park forest fire "2019.4.17" as the background of the study.After the disaster,the vegetation of Shenyang National Forest Park was seriously damaged,and some plant landscapes not only affected the forest landscape quality and ecological quality,but also seriously affected the forest park Entertainment.Therefore,through field investigation,the present situation of forest resources in Shenyang National Forest Park is investigated,focusing on the forest park overfire area and analyzing and summarizing the problems at this stage.From the point of view of plant landscape planning,it provides reference basis for vegetation landscape restoration and reconstruction in Shenyang National Forest Park,and reasonably formulates the restoration strategy.The details are as follows:(1)First of all,the evaluation system of landscape visual sensitivity is established for Shenyang National Forest Park area,and the overfire area is divided into three grades: the core landscape area of landscape visual sensitivity level,the main road scenic spot of landscape visual sensitivity level 2 and the ecological conservation area of landscape visual sensitivity level 3,and the principles and objectives of vegetation restoration are defined.(2)By investigating the tree species in some scenic spots in Liaoning Province,the common native tree species were selected,and the AHP evaluation system was established to select the tree species for restoration.The comprehensive evaluation value was obtained through the weight value and the score result,and four indexes were obtained: ornamental index,growth index,ecological index and economic index as the tree species selection which affected the plant landscape restoration in forest park.According to the conditions of plant,soil,climate and environment,the requirements of zoning and classification design are put forward,and the typical plant landscape design and partial structure allocation of tree species planning are carried out in each landscape area.(3)The plant landscape restoration strategies of three landscape visual sensitivity regions were analyzed.The restoration species were Luan tree,apricot,larch,peach,pentagonal maple and clove.This study plans the vegetation landscape of forest park according to scientific theory,which is not only a kind of protection to forest resources,but also has important economic benefit and educational value to optimize natural environment.In general,the restoration strategy of the affected area of Shenyang National Forest Park is formulated,and the model suitable for the optimal structure allocation of plant landscape restoration in Shenyang National Forest Park is put forward.
