The Scenic Beauty And Its Influencing Factors Of Tianger Forest Park In The Central Part Of The North Slope Of Tianshan Mountains,Xinjiang

Scenic beauty value stands as the aesthetic worth of the forest park.Studying the beauty of forest parks and its influencing factors have not only helped to deepen the understanding of its aesthetic characteristics,but also provided a scientific basis for the management of the beauty of forest parks.In view of this,this paper took the Tiangeer Forest Park in the middle of the northern slope of Tianshan Mountain where Picea schrenkiana var.tianshanica formed a forest community as the research object.It was based on the typical sample investigation of individual trees,forest stand and the scenic spot level as well as its public preference network questionnaire,color quantification,and field of view analysis.Mathematical statistical method was adopted to analyze the aesthetic characteristics of the P.schrenkiana var.tianshanica single tree and the beauty of the forest stand and the level of the scenic spot and its influencing.The two main aesthetic characteristics of single tree of P.schrenkiana var.tianshanica were forest structure and understorey height which were embodied in higher understorey height,obvious and straight trunk,complete and regular crown of trees,lush and evenly distributed branches with higher DBH(diameter at breast height)height and crown width.The scenic beauty of internal P.schrenkiana var.tianshanica forest was significantly and positively correlated with natural pruning,understorey vegetation cover,forest structure,average understorey height of live branch,average scenic beauty of single tree,main color layout,green,blue,and saturation.The scenic beauty of P.schrenkiana var.tianshanica forest was significantly and negatively correlated with dead and fallen trees,slope,and crown density,density of forest structure,brightness,and red.The higher scenic beauty of internal P.schrenkiana var.tianshanica forest was embodied in the natural pruning branches were obvious,the trees were regularly arranged,the understorey height of the live branches was commonly high,the understorey vegetation were growing lushly,the dead standing trees and fallen trees were less,the slope was smooth,the stand density and crown were not high,and the visibility of forest structure was good.The scenic beauty of external P.schrenkiana var.tianshanica forest was significantly and positively correlated with forest cover,main color layout,green,blue,and saturation.The scenic beauty of external P.schrenkiana var.tianshanica was negatively correlated with viewpoint,distribution of forest,terrain changes,forest canopy line,visibility range,and light,number of rear views,brightness,and red.The higher scenic beauty of external P.schrenkiana var.tianshanica forest was embodied in higher forest cover,best viewpoint with overhead view,more aggregated forest distribution,flat terrain,and smooth canopy line,range of visibility with close view,straight forward light,not too high brightness,no obvious rear view and the background of sky.The scenic beauty of viewpoints in Tianger Forest Park was significantly and positively correlated with the area of landscape,the ratio of landscape,patch weighted average area,patch shape index,perimeter area ratio,patch core area density,external average scenic beauty of forest,proportion of greenness,sky ratio,green,blue,white,saturation,yellow,brightness.The scenic beauty of viewpoints in Tianger Forest Park was significantly and negatively correlated with patch density,patch edge density,and red.The viewpoint landscapes with higher scenic beauty of Tianger Forest Park were embodied in larger visible area,higher patch core density in the visual field,more complex patch shape,and higher visible ratio of sky and forest.
