A Quantitative Study of the Landscape Characteristics of Landuse Types Based on GIS——Taking Jiangyou City as an Example

Taking the Jiangyou city as an example, the information of landuse types from RS image of the research area were extracted by using ERDAS 9.2 and ArcGIS 10.0 software. The landscape pattern index was calculated by using Fragstats 3.3 software. Then 7 indexes were selected, including landscape area(CA) in the study area, and the quantitative analysis was made of the spatial pattern of landuse landscape. The result revealed the characteristics of the study area that its forest had a wide distribution and its landscape shape was relatively regular.
