Evaluation And Control Of Rural Landscape Characteristics In The Southern Mountainous Area Of Jinan Cit

In recent years,China has launched policies such as the Beautiful Countryside and Rural Revitalization to support the sustainable development of rural landscapes.However,due to urbanization,industrialization,and the increasing commercialization of rural planning and design,some rural landscapes are becoming homogenized,and their unique characteristics are gradually being overlooked.The southern mountainous area of Jinan City,established as a unique functional area by the city government,needs more effective management,resulting in a fragmented landscape.Therefore,it is necessary to deeply study the essence of rural landscapes,explore effective management strategies,and provide theoretical support and guidance for the protection and development of rural landscapes.Based on this,this thesis selects the southern mountainous area of Jinan City as the research area.It uses Landscape Character Assessment to propose management strategies for the research area to protect the unique landscape resources across administrative regions.In terms of research methods,first,natural,social,and cultural elements are selected.With the grid method as the main method,LANMAP2 as the auxiliary method,and the superposition method as the supplementary method,the landscape characteristics of the southern mountainous area are identified through preliminary cluster identification,zoning cluster identification,and overlay identification in three stages,combined with field investigation.Then,the basic information,landscape element information,key landscape characteristics,shortcomings and advantages,and landscape style characteristics of each landscape type are described.Second,a combined quantitative and qualitative landscape decision assessment is carried out from three aspects: ecosystem services,ecological tourism suitability,and landscape characteristic sensitivity,to determine the management objectives of landscape characteristics.The evaluation of ecosystem services mainly includes four indicators: water source conservation,soil and water conservation,habitat maintenance,and carbon sequestration and oxygen release,calculated using the In VEST model.The evaluation of ecological tourism suitability mainly uses the Analytic Hierarchy Process to evaluate nine indicators in three dimensions: natural ecological conditions,ecological tourism resources,and socio-economic conditions.The evaluation of landscape characteristic sensitivity evaluates the intensity,condition/integrity,and aesthetic characteristics of the landscape.Finally,macro and landscape characteristic management strategies are proposed based on the landscape characteristic descriptions and the management objectives determined by the landscape decision assessment,aiming to provide new ideas and suggestions for managing rural landscapes in the southern mountainous area.The main results of the study are as follows:(1)This study identified 11 landscape characteristic classes and summarized them into 4 landscape zones: settlement construction zones with light,moderate,and high degrees of construction;vegetation coverage zones with high and moderate vegetation coverage;cultural and tourism construction zones,including tourism development and cultural construction zones;and ecological protection zones,including strictly protected zones,cultural zones,construction zones,and water protection zones.These zones are described in detail.(2)Through the evaluation of ecosystem services and ecological tourism,five management objectives were determined for the landscape characteristic types in the southern mountainous area: strengthening construction,innovative construction,ecological protection,ecological maintenance,and ecological optimization.Combined with the sensitivity of landscape characteristics,the management objectives are further refined.(3)Macro and landscape characteristic management strategies were proposed.In terms of macro management,it is recommended to establish a point-line-surface structure to create a stable network of ecological tourism development and ecological protection.In terms of landscape characteristic management,specific protection strategies were proposed for the 11 landscape characteristic types,including implementing ecological agriculture,protecting ecosystems,optimizing architectural styles,green restoration,smart technology,and cultural landscape influence.These strategies help promote the sustainable development and protection of the style of the southern mountainous area.The study of the rural landscape of the southern mountainous area of Jinan City based on Landscape Character Assessment breaks the regional restrictions on rural landscape management.It provides new ideas for the fragmented management of regional rural landscapes.The research method,which uses a three-step landscape characteristic type identification method,improves the accuracy of landscape recognition.Combining the specific development goals of the research area,a landscape decision evaluation method is established,providing a reasonable basis for formulating appropriate management strategies for the southern mountainous area and achieving sustainable development.
