| 摘 要： | 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。将研究区域分为耕地、林地、未利用土地、水域、牧草地、居民点及工矿交通用地、园地这7个景观类型,通过地理信息系统软件Arcgis9.2操作得出岐山县土地利用现状图。结果表明:岐山县南北两端景观基质为林地,中部景观基质为耕地。耕地占岐山县面积的53.2%,是最具优势的景观类型。在各景观类型中,耕地总面积最大,平均斑块面积最大,破碎度最小,分离度最小。园地总面积最小,平均斑块面积最小,破碎度最大,分离度最大。居民点及工矿交通用地的分布状况导致其破碎度和分离度大。

| Abstract: | 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 t... |
