With the acceleration of urbanization and the rapid development of urban economy, the urban area continues to expand outwards, and the landscape space components are constantly changing. The main manifestations are: ecological patches are fragmented, biodiversity is reduced, and the original rural field landscape is replaced by modern construction land. ; The material and energy exchange of the transportation network is not smooth, which limits the connection between species between ecological patches; the water system network is increasingly artificial, and the river channel is encroached or destroyed. The natural habitat is disturbed by man, the function of the ecosystem is reduced, and the landscape pattern is fragmented, which affects the healthy development of the urban composite ecosystem. With the change of ecological environment, species and quantity of organisms, and the interference of human activities, ecological security is changing at different scales. The study of ecological security pattern is considered to be the basic approach and important guarantee to realize and protect regional ecological security. At present, many landscape pattern studies involve the study of landscape functions and dynamic characteristics. With the help of analysis tools such as RS and GIS, the evolution mechanism of landscape pattern is studied in depth, and the status quo of landscape pattern is analyzed with the help of Fragstats landscape software. In addition, the importance of spatial structure research is emphasized. Focus on the role of spatial and temporal scales. At present, the study of landscape ecological pattern has become a hot spot of common concern in ecology, geography, urban planning and other disciplines.
