基于GIS的土地利用类型景观特征定量研究——以江油市为例

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

  • 摘要: 以江油市为例,应用ERDAS 9. 2和ArcGIS 10. 0等软件对研究区Landsat ETM+遥感影像进行土地利用类型的解译。采用Fragstats 3. 3软件计算景观格局指数,选取景观类型面积(CA)等7个指标,对研究区土地利用景观空间格局进行了定量分析,揭示了研究区土地利用类型林地分布广、景观形状较规则等特征。

     

    Abstract: 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.
