- Abstract:
- We selected Hongsibu as the study area, and used the remote sensing data of 2015 and RS, GIS and Fragstats 3.3 to explore landscape index characteristics with grain size change and the area loss, and ultimately determined the optimal grain size for analyzing land-use landscape pattern. We considered four aspects of landscape elements:spatial pattern, spatial form, spatial relations and spatial configuration. The results showed that some landscape indices and grain size could be fitted to a mathematical relationship, and the determined optimal grain size was 80 m. Grass was the main land-use landscape type across the study area, accountiong for 61.8%, the distribution of cultivated land and forest land in the study area is more uniform. The whole landscape was small heterogeneity and composed of large patches. The shape complexity was moderate, the degree of fragmentation was not serious and landscape stability was poor.
