城市森林景观动态变化与驱动力分析——以沈阳市铁西区为例

Dynamics of urban forest landscape and driving forces: A case study in Tiexi District of Shenyang City

在遥感和GIS技术的支持下,借助各种遥感影像,采用转移矩阵和景观斑块变化类型的分析方法,对2001～2011年沈阳市铁西区大中型(面积大于400m2)城市森林景观动态变化进行分析。结果表明:10年间,铁西区各类型用地相互转化频繁,大中型城市森林斑块总面积和总数量都呈现先增后减的趋势,斑块整体水平向中小型化发展。而工业用地、企事业单位用地和其他用地中的斑块更新度高。研究区域以工业迁移因素为核心,经济发展、人口增长及管理因素成为景观动态变化的主要驱动力。

Supported by remote sensing（RS）and the geographic information system（GIS）and a variety of remote sensing image, the dynamic changes of the medium-sized（area greater than 400 m 2 ）urban forest landscape form 2001 to 2011 in Tiexi zone in Shenyang city were analyzed using the analysis methods of transfer matrix and the change types of landscape patch. Result indicated that various types of land chance to each other frequently orrured in Tiexi zone. The size and quantity of the medium-sized urban forest patch was the first growth after a downward trend in Tiexi zone. The plaques developed to small and medium-sized technology. And a high degree of patch freshness in industrial land, enterprises land and other land. The industrial migration factors as core in the study area, economic development, population growth and management factor were the main driving forces of urban forest landscape dynamics.
