Construction And Optimization Of Slow Landscape Pattern Based On Resistance Model

Under the influence of slow culture,slow landscape is a highly integrated natural landscape and human landscape.Through landscape construction,it is a geographical space complex that can relieve stress and relax during the landscape experience.It adapts to the future leisure lifestyle and urban development of people.How to reveal landscape function from the perspective of landscape pattern is an important theme of landscape ecology research.This paper takes Gaochun Slow City as a research case,with the support of Arc GIS technology,uses the minimum cumulative resistance model to generate a slow landscape corridor,build a "source patch-landscape corridor-natural base" slow landscape pattern,and analyze the composition of the slow landscape And spatial pattern characteristics;use the gravity model to calculate the interaction strength between the landscape source patch and the target patch,identify the important corridor of the slow landscape based on the matrix gravity value,and take the intersection and important turning point of the corridor and corridor as the important landscape Node,and finally put forward corresponding optimization suggestions based on the above analysis.Through this study,the following research conclusions were drawn:(1)Gardens,woodlands,and construction land are not only the main types of land used for source patches,but also important types of land that constitute the slow landscape corridor of Gaochun Slow City.Among the source areas,construction land accounts for 37.02%,forest land accounts for 23.85%,and garden land accounts for18.86%;in corridors,garden land accounts for more than 25%,forest land accounts for 11%-22%,and construction land accounts for approximately 15 %-20%.(2)The spatial distribution of landscape patches in Gaochun Slow City is obviously different.Cultivated land patches are mainly concentrated in the east and west,and woodland-garden-grassland patches are concentrated on both sides of the ecological journey.Building patches and water patches are scattered;the overall network of the water system is evenly distributed without obvious banding characteristics;roads The corridor takes the ecological journey as the main axis and runs from northeast to southwest.(3)The landscape pattern of the slow landscape of Gaochun Slow City presents the characteristics of “taking farmland as natural substrate,architecture and scenicspots as core patches,and roads and woodlands as landscape corridors”.(4)A total of 105 landscape corridors are generated using the minimum cumulative resistance model,and 42 basic corridors and 45 optimized corridors are extracted through the gravity model,and a total of 15 important landscape nodes are identified as temporary resting places in the landscape corridors.The key node locations of Gaochun Slow City need to be planned,constructed,and repaired.(5)Four points of optimization suggestions were proposed for the slow landscape planning of the slow city of Gaochun: improving the core patches of the slow landscape,increasing the effective connection between the patches,constructing an important corridor of the slow landscape,and strengthening the connection of the core patches outside the area.It is also recommended to construct an optimized structure of "one heart,four cores,five belts and triangles" for the slow landscape pattern.
