【摘要】A case study was conducted in Qishan County, Shaanxi Provence by using remote sensing images, and selecting indices of landscape diversity, fragmentation and isolation, to analyze the landscape spatial patterns. The whole area was divided into seven landscape patterns: farmland, forest, unutilized land,water area, pasture, land for resident/industry/mining/traffic, and fruit garden. A land utilization map of Qishan County was produced by running the geographic information system software Arcgis9. 2. The results showed that in the north and south of Qishan, the landscape matrix was foresta and in the middle was farmland. The farmland occupied 53 ％ of the total area of Qishan, and was the most dominant landscape pattern. Among all landscape patterns, the farmland had the largest area, largest average patch area, the lowest fragmentation, the lowest isolation. Fruit garden had the smallest area, the smallest average patch area, the highest

fragmentation,

the

highest

isolation.

The

land

for

resident/industry/mining/traffic had higher fragmentation and isolation, this was because of its special distribution.%以岐山县为研究实例,选取景观多样性、破碎度、分离度等指标,利用遥感影像对该区的景观空间格局进行分析.
