基于GIS的陕北景观结构

Landscape Pattern of Northern Shaanxi Based on GIS

以陕西土地利用现状图作为数据基础,应用Arc/Info和Arc/view等GIS专业软件,对陕北地区的景观进行了分类,并形成了景观分类图。利用景观格局分析软件FRAGSTATS,在斑块类型和景观两个水平上计算了相应的参数和景观指数,定量揭示了整个区域的景观格局与类型特征。为进行深入研究和揭示生态过渡地带生态过程奠定了基础。

Taking the landuse actual map as the data base,this paper classifies the landscape of northern Shaanxi and makes into the landscape classification map using ARC/INFO,ARCVIEW and other Geographic Information System professional software. Using the landscape pattern analysis software FRAGSTATS,this paper calculates relevant parameters and landscape indices on patch category and landscape level, and reveals the landscape pattern and type character of the whole region quantitatively. This paper establishes the foundation for the deeper researching and the revealing of ecological process in transition regions. It has some reference value on the interrelation between the rebuilding of region landscape and function process, forecasting landscape dynamic changing and so on.
