In order to explore landscape pattern traits of elm open forest in the center part of Hunshandake Sandland, northern China, the number, area, and shape index of landscape patch for elm open forest have been analyzed through the method of field survey and 3S technological applications. Spectral heterogeneity of sample plots is calculated using Landsat satellite TM images (6 bands, spatial resolution of 30m). The results indicate that there exist 100606 landscape patches in the center part of Hunshandake Sandland. However, the area of most patches (77%) is smaller than 0.5hm², and patch shape index reaches at 0.11 averagely. Furthermore, the relationship between area and its shape index is also simulated using software SPSS, it is indicated that patch shape becomes more complexity with the decrease of patch area. These facts indicate that landscape fragmentation in elm open forest in the center part of Hunshandake Sandland is very serious, and needs to be immediately protected., authors=PENG Yu^1,2, JIANG Gaoming², GUO Luo¹, LIU Meizhen², XUE Dayuan¹, authorsList=PENG Yu;JIANG Gaoming;GUO Luo;LIU Meizhen;XUE Dayuan, authorCompany=1.
