| The red leaves hill of Badaling national forest park has attractive,early,wild,near four characteristics in autumn and attracts a large number of tourists to come to watch.As an important tourist attraction in Beijing area,using the visualization technology to change the configuration of the color patches and a reasonable design is made,then use the SBE beauty evaluation method to judge the landscape pictures,deal with and analyze the evaluation results,and discuss the influence of the change of color patches on the landscape quality.It is of great significance to improve the landscape quality of the scenic spot.By means of the landscape pattern index in landscape ecology,this study objectively evaluated the influence of the spatial pattern changes of gray and green patch area,the total area of main color patches,the degree of patch aggregation and the area of the largest main color patch on the aesthetic quality of the autumn forest.The main conclusions were as follows:(1)The area ratio of green patches and gray patches had a significant effect on the beauty of the autumn landscape,With the increase of green patch area in the field of view,the area of gray patch was reduced,and the landscape quality increased firstly and then decreased;(2)The total area of color patches and the degree of plaque aggregation had significant influence on the quality of the landscape forest.With the increase of color patch area in the field of view,the landscape quality of the mixed landscape forest was constantly improved.With the enhancement of the degree of plaque aggregation,the landscape quality of the mixed landscape forest had declined continuously;(3)The change of the beauty level had a significant impact on the landscape index.Through the simple correlation analysis,six indices were selected which were significantly related to the beauty of the landscape:(NP),(PD),(LSI),(MPAR),(PLADJ),(AI).Among them,NP,PD,LSI,MPAR were positively correlated with the beauty level,PLADJ and AI were negatively correlated with the beauty level.The influence degree of each landscape index on scenic beauty is PD>AI>LSI>PLADJ>MPAR>NP.(4)The total area of color patches had significant effects on NP,PD,LSI,PLADJ,and AI With the increase of the total area of color patches,NP,PD,and LSI increased,AI and PLADJ decreased.It showed that the landscape beauty increased with the increase of color patch area.The degree of plaque accumulation had a significant influence on AI,As the degree of plaque aggregation increased,AI was also increased,and the quality of landscape decreased.The interaction between the total area of the main color patch and the degree of plaque accumulation had a significant influence on LSI and AI.When plaques were low-aggregated,LSI showed a tendency of increasing first and then decreasing with the increase of the total area of main color patches.AI showed a gradually decreasing trend.When patch plaques were evenly distributed,with the increase of the total area of main color patches,LSI showed a gradual increasing trend,and the AI index was not significant with the increase of the area of the main color patch.When the plaques were highly aggregated,LSI showed a gradually increasing trend with the increase of the total area of the main color patches,and AI showed a decreasing trend.(5)The six indices obtained from the simple correlation analysis were analyzed by principal component analysis,two new indexes were built:F1 shape and aggregation index,F2 quantity index.F1=0.87PD+0.938LSI+0.853MAPR-0.947PLADJ-0.898AI F2=0.959NP... |
