Landscape Pattern Evolution And Ecological Quality Evaluation Of Mulan Cultural Ecotourism Area In Huangpi,Wuhan

With the vigorous development of the rural tourism industry,the ecological and sustainability issues of tourist destination landscapes have attracted increasing attention.In recent years,the Huangpi Mulan Cultural and Ecological Tourist Area has been constantly developing.The construction of scenic spots and the growth of tourists have caused changes in the landscape pattern.Taking Mulan Cultural and Ecological Tourism Zone in Huangpi District of Wuhan City as the research object,using Arc GIS 10.6,Fragstats 4.3 and other software,the three-phase remote sensing images of 2000,2012 and 2020 were interpreted and analyzed,and their land was explored in the past 20 years Changes in cover and landscape patterns.Based on the current landscape pattern status and tourism development status of the study area,the ecological quality is evaluated through the "pressure-stateresponse" model,which provides reference and guidance for the sustainable development of rural landscape planning and tourism areas based on the evaluation results.The main conclusions are as follows:(1)In the development of the research area in the past 20 years,the area of cultivated land has declined the most,and forest land and construction land are the types of land with the largest increase in area.By 2020,the forest land coverage rate in the study area has reached more than 50%.With regard to the dynamic changes in land use types,there is a phenomenon of mutual transformation of various landscape types in different periods.The change in land cover types in the latter period is more dramatic than in the previous period,indicating that the landscape spatial structure in the study area has suffered and the impact of human activities is getting stronger.(2)In terms of changes in the landscape pattern index,the overall degree of regional landscape diversity,the complexity of the spatial structure and the degree of human disturbance all have increased.At the same time,there are dominant plaque types in the region,the overall fragmentation of the region has decreased,and the ecological situation is improving.(3)According to the comprehensive evaluation of the overall ecosystem health status of the study area by the "stress-state-response" model,the overall score of the Mulan cultural and ecological tourism area is at the first level,which is in an excellent state.The overall ecological structure of the region is relatively reasonable,and the landscape pattern is relatively balanced.Although it is under greater pressure from the outside,the ecological flexibility is very good,and the overall ecosystem is stable and sustainable.(4)In regional development,there are situations in which construction input-output is relatively low and resource utilization efficiency is low.Regional development is relatively poor in response and lacks innovation.While protecting the environment,we should improve the level of regional operations and management,make more intensive use of existing resources,increase residents’ income levels and regional influence,and achieve coordinated development of the environment and society.
