Landscape Pattern And Scenic Beauty Optimization In The Yulong River Area

Environmental protection and building an ecological civilization is a basic national policy of China.The 18 th National Congress of the Communist Party of China put ecological civilization construction on the level of national strategy.The 20 th National Congress of the Communist Party of China considered that it would continue to promote the project of sustainable development and the harmonious coexistence between man and nature.The karst plain attracts many tourists with its unique landform landscape,but the karst ecosystem is extremely fragile.How to realize ecologically sustainable development based on developing a tourism economy is an important content affecting the construction of ecological civilization in the karst plain.Yulong River Basin,a typical karst plain landscape,its environment and landscape quality are of great importance.However,with the flourishing of tourism in the Yulong River Basin,the pressure on the local ecological environment is increasing,and the task of landscape resource conservation is heavy,in urgent need of a comprehensive,systematic,and targeted landscape optimization study.First,from a macro perspective,the vigorous development of tourism in the Yulong River Basin in the past 30 years has resulted in the explosion of construction land,occupying much farmland and forest land,leading to the intensification of landscape fragmentation and the reduction of landscape connectivity,and threatening the security of regional landscape pattern.Based on the analysis of landscape pattern evolution,combined with the upper planning,site conditions,and future development needs,the optimization objectives and strategies of landscape patterns in the Yulong River region were proposed,including protecting important ecological source,rationally planning land use structure,integrating landscape fragments and strengthening landscape corridors.Secondly,from the micro level,the landscape beauty degree method is used to determine the landscape elements that have an impact on the beauty degree of the water landscape,building landscape,and farmland landscape.The results showed that the overall quality of the water landscape was high,which had a critical impact on the landscape beauty of the Yulong River.The quality of farmland and the architectural landscape need to improve.Based on the evaluation results,the optimization design of each landscape type was carried out purposefully.The water landscape was optimized from the form of river,waterfront plants and embankment,the farmland landscape was optimized from the cultivation method and plant season,and the architectural landscape was optimized from the architectural style,color and height.Unique geomorphic landscapes and a good environment are the original driving force of tourism development in the karst plain area.It is of great significance to understand the impact and feedback of ecological environment and landscape quality brought by tourism development and formulate corresponding environment protection and landscape beauty enhancement policies for a sustainable tourism economy and ecological sustainability in the karst plain area.
