Applying ArcGIS GIS software, we vectorized the data of mangrove and longisongrass tussock vegetation in “China Vegetation Atlas (1:1000000)” issued by Science Press in 2001, obtained the patch information of Miscanthus sinensis, Eulaliopsis binata community vegetation, and used it to draw the geospatial distribution maps of Miscanthus sinensis, Eulaliopsis binata community vegetation, and studied the main distribution areas and patch characteristics of China’s Miscanthus sinensis, Eulaliopsis binata community vegetation. The results showed that China’s Miscanthus sinensis, Eulaliopsis binata community were mainly distributed in Shaanxi, and a small amount of them were distributed in Henan, Guangxi and Guizhou. The total number of Miscanthus sinensis, Eulaliopsis binata community vegetation patches is 109, with a total area of 5146.87 km2. The number of Miscanthus sinensis, Eulaliopsis binata community vegetation patches is 106, with an area of 5030.89 km2, and the number of Miscanthus sinensis, Eulaliopsis binata community + Eulaliopsis binata community vegetation patches is 3, with an area of 115.98 km2. Overall, the shape of patches of each Miscanthus sinensis, Eulaliopsis binata community group system is relatively regular. The size of the patches of Miscanthus sinensis, Eulaliopsis binata community varies greatly in size and the degree of landscape dispersion is large, and the patches of Miscanthus sinensis. Eulaliopsis binata community + Eulaliopsis binata community have a higher degree of fragmentation and are more affected by human activities. %K 芒草， %K 龙须草草丛， %K 地理分布， %K 斑块特征， %K 景观生态学
