| With the successive proposals of national policies such as rural revitalization strategy and ecological civilization construction,tourism-oriented towns and towns have developed rapidly by virtue of their own good ecological background and rich cultural tourism resources.During the development and construction of tourism projects,other ecological land,especially cultivated land and garden land,will often be occupied,which will lead to changes in the landscape pattern and affect the original natural ecosystem.In order to sustain the sustainable development of tourism-oriented townships,the protection of its ecological environment should be strengthened,but at the same time,it is not possible to protect the ecology in a one-size-fits-all manner.Under this background,it is of great significance and value to coordinate ecological construction and tourism construction to optimize the landscape pattern of tourist towns.This paper takes Jiulong Town,a tourism-oriented township as the research object,based on the theories of landscape ecology and sustainable development,using software technologies such as Arc GIS and Fragstats,and based on the land use vector data in 2008,2014 and 2020,established Jiulong.Classification system of town landscape land types.Based on the land use dynamic index,landscape type transition matrix and landscape pattern index,this paper studies the changes in the number of landscape land types,the dynamic degree changes,and the spatial changes of landscape land types in Jiulong Town in 2008,2014 and 2020.The temporal and spatial evolution characteristics and laws of the landscape pattern of Jiulong Town from 2008 to 2020 were analyzed.The landscape ecological network of Jiulong Town is constructed from the perspectives of ecology and recreation.Based on the MSPA analysis method,Arc GIS software and Guidos software were used to extract the ecological core area of Jiulong Town.From the perspectives of patch area and patch connectivity importance index,the ecological source areas of Jiulong Town were screened out.According to the tourism resource space of Jiulong Town Recreational sources are extracted from the distribution;ecological comprehensive resistance surface and recreational comprehensive resistance surface are constructed respectively;based on the MCR model,Arc GIS software is used to extract the corresponding potential ecological corridors and potential recreational corridors,and the gravity model is used to extract important ecological corridors;According to the intersection of each corridor,ecological nodes and recreational nodes are extracted;finally,the ecological network and the recreational network are superimposed to obtain the Jiulong Town landscape ecological network.According to the results of the analysis of the temporal and spatial evolution of the landscape pattern in Jiulong Town,the existing problems of the landscape pattern are put forward,and the optimization principles of the landscape pattern are put forward by using the theories of landscape ecology and landscape ecological planning,and the optimization goal of the landscape pattern is proposed based on the natural and social conditions of Jiulong Town.On the basis of the construction of the landscape ecological network,the landscape ecological sources,landscape ecological corridors and landscape ecological nodes of Jiulong Town are classified,and optimization strategies are proposed for them to improve the ecological stability and connectivity of the landscape pattern.And diversity,to achieve the purpose of optimizing the landscape pattern of Jiulong Town.The research methods and conclusions of this paper will provide reference for Jiulong Town’s land use planning,tourism planning,ecological space planning,etc.,and provide experience for the optimization of landscape pattern in other tourist-oriented towns and towns in China. |
