| In this study,we took the research in Nanping Fengshan Forest Park.Based on the investigation of forest resources II in 2015 and the field investigation,we analyzed the composition and spatial pattern of forest landscape from the forest patch size,patch shape,fragmentation,landscape diversity to assess the current station of this area.In addition,we assessed the aesthetic quality of the forest landscape and analyzed the relationship between forest landscape elements and beauty degree with the method of beauty degree evaluation.Furthermore,the measures of aesthetic control were proposed,which would be the reference for the management and design of this study area.The main conclusions were:(1)Based on the research of patch size,patch shape and fragmentation of forest landscape,the mixed forest of coniferous and broad-leaved,mixed forest of broad-leaved and mixed forest of coniferous were the three main types of landscape,with a total area of148.25 hm2,accounting for 67.82%.The area of Schima superba,Camphor tree and cutting area were the inferior forest landscape types,only accounting for 4.04%,2.61%and 0.96%,respectively.It can be known that the distribution of landscape types in the study area is extremely unbalance.The patch perimeter of the coniferous and broad-leaved mixed forest landscape was 13.78 km,which was the longest.However,the perimeter of the landscape patch was only 0.82 km,which was the shortest.With an unstable state,the mixed forest of coniferous and broad-leaved was the most complex in the plaque shape of forest landscape.The landscape fragmentation index of Schima superba was the highest and that of broad-leaved mixed forest was the smallest,which affected by human activities.The results showed that this study area was a low-diversity,unobvious-heterogeneity and uniform forest landscape by forest landscape diversity analysis.According to the analysis of the richness and dominance index,the three types of mixed forest were predominate.Due to the status of forest landscape pattern in the study area,reasonable management and protection measures should be taken to protect and enhance the diversity and heterogeneity of the forest landscape.We should increase the construction of other landscape types and reduce the impact and damage of human activities to prevent the fragmentation of landscape types.(2)We took the eleven landscape elements,which influenced the aesthetic quality of forest landscape,as the evaluation index and evaluated the forest landscape types by the beauty assessment method in the study area.The results showed that the order of average SBE of the landscape types was:Pinus massoniana>Phyllostachys pubescens>Cinnamomum camphora>coniferous and broad-leaved mixed forest>broad-leaved mixed forest>Schima superba>coniferous mixed forest>Pinus massoniana.(3)When analyzed the relationship between the forest landscape elements and the beauty degree of Fengshan Forest Park,the results showed that forest height of the understory had the greatest contribution to the beauty of forest landscape.The others were:the uniformity of forest understory,perspective degree,forest understory coverage,color change,trunk shape and natural pruning.With the straight tree trunk,rich tonals,obvious natural pruning,neat forest understory and low height of the forest,the beauty value of the forest landscape was improved.When the understory coverage and perspective were at the middle level,the beauty degree reached the best value.Otherwise,the beauty of the forest landscape value would be decreased.(4)According to the research of forest landscape and aesthetic quality evaluation of Fengshan Forest Park,the problems of forest landscape were:monotonous landscape,single tree species,lack of hue and seasonal changes,unreasonable forest difference,unreasonable forest density,clutter forest understory.Due to the shortages of the present situation of the forest landscape and the aesthetic value of the landscape,we should take the control measures:adjust the performance of the forest,improve the tree species composition,the level structure and spatial combination of landscape,cultivate seasonal forest,enrich the forest landscape,improve the cleanliness of forest land and increase forest permeability and accessibility. |
