Forest Landscape Pattern Analysis And Aesthetic Research Of North Luoxiao National Forest Park In Hunan

Hunan North Luoxiao National Forest Park, is based on Central South University of Forestry & Technology Lu Tou experimental forest on the draw and part of the production and operation area of scientific test area, re-declaration a new national forest park. It’s a key base for the field to develop forest tourism and professional training on forestry technology. It has a wide range of flora and fauna, significantly the development and utilization while protecting the park itself. It is the premise of protection and utilization of forest landscape pattern analysis and aesthetic value.In this paper, the Hunan North Luoxiao Forest Reserves has been selected as the research object, supported by ArcGIS & SPSS, analyzing via AHP, MSMPP, TOPSIS, SBE based on the data from the 2009 type 2 survey data in North Luoxiao, DEM data and field survey data as the standard data plot source. Researched on primary & secondary landscape pattern and representative forest landscape aesthetic quality to analyze. Establish an effective and objective aesthetic evaluation of the number of multiple linear regression model, optimize and improve the management model provides a theoretical basis for the study area forest landscape. The main results are as follows:(1) On patch types level, the 1st-class landscape types are unevenly distributed, mainly in the plain woodland, bamboo forest and immature forest-based, where the highest dominance of pure forest, and gathered high and low resolution, the surrounding landscape is more abundant, waters and vice versa; the ratio of the area occupied by 2nd-class landscape types vary greatly in eight categories,91.85% of the total area of the fir forest, the broad-leaved forest and bamboo forest, of which the broadleaf forest dominance higher up, and the degree of aggregation, plaque cohesion big, natural connectivity is better, the situation is more complex adjacent to the surrounding space, exotic pine is in a completely different situation. On landscape level, forest landscape type 2nd-class on dominance is lower than type 1st-class, type of patch and its high degree of distribution uniformity, high degree of fragmentation.(2) 1st-class and 2nd-class landscape types have a certain relevance on topography elevation, slope & aspect. Based on the elevation factors, a landscape of pure forest, mixed forest bamboo forest, the immature forest and the distribution area of cutting sites with increasing elevation level showed a trend of increasing first decreased, the proportion of the area occupied by 1-6 height also showed a decrease trend after an initial increase, reaches a maximum elevation in the level three; each 2nd-class landscape types distributed by elevation great impact on the forest landscape level three elevation of the most abundant. Based on the slope factors, the overall distribution of various 1st-class landscape types with increasing grade levels increased first increased and then decreased trend; various 2nd-class landscape types on each patch area and have apparent difference. Based aspect factors, each 1st-class,2nd-class landscape types in the distribution of each aspect are unbalanced.(3) Elevation, slope, aspect and research forest landscape pattern and have some relevance.500-700m elevation zone where is the most suitable zone to survive for 1st-class and 2nd-class landscape types, the two types of landscape fragmentation degree increased with increasing elevation level after first decreased and then increased, each spot in altitude compared to low altitude and high altitude block type distribution is uniform, low dominance.20°-30° slope of 1st-class,2nd-class landscape type’s most livable areas, and two types of landscape fragmentation degree increased with increasing grade levels after the first decreased and then increased, and the 2nd-class landscape type fragmentation degree than the 1st-class landscape type level serious. 1st-class,2nd-class landscape type patch number distribution descending order are:half negative slope> half positive slope> shady slope> sunny slope, they are in the western slope of the highest degree of fragmentation, 1st-class,2nd-class patch types respectively mountains, southwest slope distribution is more uniform, lower dominance, rich forest landscape, in the southeastern slope vice versa.(4) The analysis AHP, modified simplex method-projection pursuit method, TOPSIS method and the scenic beauty of the method in the study area 21 plots of forest landscape aesthetic evaluation of the effect of the results of the evaluation found that the four methods were effective, high confidence reflect the overall characteristics situation. Then comprehensive analysis of SBE is an ideal method of Hunan North Luoxiao National Forest Park forest landscape aesthetics evaluation. Based on the results of SBE, operation analysis by SPSS, the establishment of a scientific, effective and objective of the study area forest landscape aesthetic evaluation of multiple linear regression model.
