| Tourism is an important part of the world's economic and cultural development.In China,tourism has entered a period of rapid development with great potential.While the rapid development of tourism has brought considerable economic benefits,it also brought problems such as increasingly severe land-use landscape pattern disturbance,destruction of tourism resources,environmental degradation of tourist areas and others.Landscape,as the basic spatial unit to study and maintain sustainability,is the minimum scale for studying the relationship between nature and society.In recent years,the study of landscape pattern evolution and its driving factors has become a focus in the research of international land use and of tourist landscape.Dongping county is rich in tourism resources.In recent years,based on natural geography and cultural accumulation,tourism in Dongping county has been improved quite a lot and has become a pillar industry in the county's economic development.In this process,as a traditional agricultural county,its land use and tourism landscape pattern has undergone great change.The extent of the change,how the change happens,its spatial and temporal characteristics,as well as its impact on land use,industrial and agricultural production,economy and society in county areas,all these aspects need to be studied.Therefore,this paper takes Dongping county as the case area,using RS,GIS technology and survey and statistical methods,based on the analysis of tourism development,studies characteristics of the evolution of county tourism landscape pattern,simulates the future tourism landscape pattern scenario,and puts forward countermeasures for tourism development,landscape construction and land use.Taking tourism resources as the research object to explore the evolution characteristics and drivers of tourism landscape pattern is of great significance to construct a good ecological environment,improve the livability and travel of the whole region,and promote the policy of poverty alleviation and agriculture.This study aims to analyze the countermeasures of tourism development and landscape construction in Dongping county based on RS and GIS technology and survey and statistical methods.The results are as follows:(1)Analysis of the condition of tourism development in Dongping county.Based on natural resources,social economy and other conditions,it summarizes the tourism background,tourism landscape and tourism infrastructure construction of Dongping county.Based on the situation of natural tourism resources and humanistic tourism resources,the status of resource development and utilization in Dongping county was analyzed,and the development strategy of tourism industry and the construction of tourism environment were analyzed.The results show that,Dongping tourism development has a high level of scenic spots,a large number of scenic spots,a deep cultural heritage,a high brand effect,convenient transportation and accessibility,a high degree of government attention,and scientific planning and positioning.There are also strategic lack of tourism development planning and infrastructure.The construction of supporting facilities with scenic spots is incomplete,the integration of culture and tourism is poor,there are core attractions but no core competitiveness,the tourist source market is limited,and it is in the disadvantage of being located in the shadow area of tourism.(2)Analysis of the spatial and temporal evolutionary characteristics of tourism landscape pattern in Dongping county.Based on the 3S technology,the landscape pattern of Dongping County in 2005,2010 and 2015 three typical years was studied to explore the spatial and temporal characteristics of the landscape pattern of the study area,using the combined method of supervised and unsupervised classification.The Kappa coefficient of the interpretation precision was over 0.8,and the overall precision was over 90%,which meets the needs of the research.Based on the national land pattern classification standard,the surface landscape pattern is divided into two categories:tourism landscape(natural ecological landscape,water landscape and architectural landscape)and non-tourist landscape(agricultural landscape and other landscape),with an respective area of 323km~2 and 1020km~2 in 2005,331km~2 and1012km~2 in 2010,and 364km~2 and 979 in 2015km~2.Between the year 2005 and 2015,the overall area of tourism landscape pattern in Dongping county had increased,and the non-tourism landscape pattern had decreased.The increase of tourism landscape pattern is mainly realized by the transformation from agricultural landscape to architectural landscape.The spatial pattern of tourism landscape is spreading outward along the county seat of Dongping and the coast around Dongping Lake.At present,the agricultural landscape pattern is still the main landscape type in the study area,and the area of non-tourism landscape accounts for more than 70%of the total area.(3)Simulated prediction of tourism landscape pattern in Dongping county.The CA-Markov model was adopted to predict the landscape pattern of the research area,and it was found that the total area of the county's tourism landscape would reach 374km~2 by 2025 and383km~2 by 2030.In the next 10 to 15 years,the area of the tourism landscape pattern in the study area will continue to increase,and the area of the non-tourism landscape pattern will continue to decrease.The change is mainly the shift of the agricultural landscape pattern to the architectural landscape pattern.The change areas are mainly concentrated in Dongping county and the coast around Dongping Lake,while the water landscape pattern and the natural ecological landscape pattern change is not obvious.(4)Measures for the tourism development and landscape pattern regulation in Dongping county.Facing the construction of ecological civilization,Dongping county's tourism development and landscape construction should take the excavation of cultural heritage as the link,develop cultural and tourism projects,develop development plans,and shape a new brand of cultural tourism by deepening the excavation of connotation;Improve the planning system,give priority to the construction of the main line,enhance the reception capacity,refine the functional zoning,and optimize the new tourism network in the county;take rich innovation products as the starting point,through the enrichment of tourism products,introduce and cultivate professional talents,expand the new experience tourism market;use green ecological restoration As the main body,carry out ecological restoration of wetlands and mines,and build ecological forestry to build a new layout of the industrial structure;take the integration of the industrial chain as the traction to build a new layout of the industrial structure.Based on the analysis of tourism development and landscape evolution in Dongping county,this study makes simulated prediction of the future condition of Dongping county's tourism landscape pattern,and puts forward the regulation countermeasure of tourism development and landscape pattern,and the results of the study have a comprehensive understanding of Dongping county's tourism landscape evolution and its tendency is of practical significance for the scientific control,management and good use of county land,as well as for promoting the development of Dongping county's tourism in a high quality. |
