基于RS的土地利用景观格局分析——以淄博为例

RS based analysis on the landscape pattern of land utilization:a case study for Zibo

以淄博市为研究对象,在Erdas软件支持下对1990年、1995年、2000年和2005年遥感图像进行解译及预处理,获取了其土地利用情况.使用ArcView软件对时间序列上的土地利用进行交叉列表统计,得到了各土地利用类型的转换矩阵,并应用空间分析模块从图像中提取各斑块信息,计算了各种景观格局参数.利用景观生态学研究方法,从景观类型水平和景观水平2个层次对淄博市1990—2005年的景观格局动态变化进行定量分析.结果表明,淄博市的景观格局发生了显著变化,各景观类型(水域、草地除外)的平均斑块分离度总体来说增加,景观多样性较高但总体呈下降趋势,景观异质性降低.

Zibo city is taken as a research object in this study.In support of Erdas,interpretation and pretreatment of remote sensing images(1990,1995,2000 and 2005) is carried out,so the land use situation is gained.By using the Tabulate Area functions of ArcView,the land use on the time series is shown as the corresponding transformation matrix.The plaque information is extracted on basis of Special Analysis module and then some landscape pattern parameters are calculated.With the method of landscape ecology,from the level of landscape and its type,the analyses on the dynamic changes of landscape patterns of Zibo during 1990 to 2005 are carried out.The results showed that Zibo's landscape pattern had a remarkable change,that the average patch isolation degree increased generally(except the waters and the grassland),and that Zibo's landscape diversity was high,but appeared the overall declining trend,so did the landscape heterogeneity.
