Research On Forest Landscape Evaluation And Optimization Of Taipeng Mountain National Forest Park

With the economic development and social progress,people's spiritual and cultural needs have shown a trend of diversification.Returning to nature and experiencing nature have gradually become an important pursuit of a better life.The forest park is popular with people for its good ecological function,landscape function and leisure function.Therefore,it has become a hot topic to optimize forest landscape and improve forest ecological environment.This thesis selected Taipeng Mountain National Forest Park in Yingshan County,Nanchong City,Sichuan Province as the research object,and comprehensively analyzed the forest landscape status and forest landscape spatial pattern in the study area,and summarized the spatial pattern characteristics of forest park landscape;A set of forest landscape quality evaluation index system was established,and the analytic hierarchy process was used to build the forest landscape quality evaluation model of the forest park,and the quantitative and qualitative evaluation methods were used to carry out the forest landscape quality evaluation;On this basis,an optimized promotion plan was proposed for the forest landscape of Taipeng Mountain National Forest Park.The research conclusions and results of this thesis are as follows:(1)By consulting the literature,the relevant concepts and theories of forest parks,forest landscapes,forest landscape evaluation,and forest landscape optimization and promotion were systematically researched and combed.On this basis,the research status of forest landscape evaluation and forest landscape optimization and promotion at home and abroad was analyzed.The current techniques and methods of forest landscape evaluation and optimization were summarized.(2)With the help of the second-class survey data of forest resources in 2018,combined with the remote sensing data from Landsat 8 satellite in 2017,the forest landscape types of forest parks in Arc GIS software were divided into 7 categories,and the landscape type maps were generated.And the patch characteristics,landscape heterogeneity,and landscape diversity were calculated and analyzed by FRASTATS software to provide data support for quantitative evaluation.Combined with terrain factor analysis,it was concluded that the distribution of forest landscape was closely related to the terrain factor.(3)From the perspective of forest landscape optimization and improvement,12 forest landscape quality evaluation indicators were selected in three aspects of forest landscape spatial pattern characteristics,ecological characteristics,and ornamental characteristics,including 7 quantitative indicators and 5 qualitative indicators.Thus,an index system for forest landscape quality evaluation was established.AHP was used to determine the weight value based on importance.The forest landscape plant health status score was 0.539,the forest landscape plant nativeness score was 0.1638,the forest landscape plant species diversity score was 0.2973,the forest landscape color and seasonal phase score was 0.2191,and the forest landscape hierarchy richness score was 0.3617,forest landscape rareness score was 0.065,forest landscape ornamental feature richness score was 0.1668,forest landscape and environment coordination score was 0.1875,forest landscape diversity score was 0.4231,forest landscape patch density score was 0.1225,forest landscape separation score was 0.2272,The forest landscape uniformity score was 0.2272.(4)The forest landscape of the Taipeng Mountain National Forest Park was evaluated by combining quantitative and qualitative methods.The forest landscape quality evaluation score was 4.89 points,the comprehensive evaluation value was 49%,and the landscape quality level was 3,which was lower middle level.In the criteria layer of the evaluation system,the forest landscape ornamental features received the highest scores.The index factors with lower scores in the index layer were: forest landscape ornamental feature richness(4.28 points),forest landscape color and season phase(2.01 points),Rareness of forest resources(2 points).(5)Based on the evaluation results,the optimization of the forest landscape was studied.Starting from strengthening the use of colored leaf plants,enhancing the ornamental nature of forest landscapes,expressing the level of forest landscapes,and increasing the diversity of forest landscapes,plans to optimize and enhance conservation forests in typical scenic spots,linear landscape zones,general recreation areas,ecological conservation areas in core landscape areas were proposed.
