| 摘 要： | 运用遥感、GIS技术与景观生态学的研究方法相结合,以天祝草原为研究对象,以2006年Landsat TM影像为基本信息源,通过计算景观组分的面积（CA）、景观类型百分比(PIAND)和斑块个数（NP），基本清楚了研究区的总体景观分布是草地与林地构成了研究区景观的主体,草地是整个景观的基质；并从高程、坡向和坡度3个方面定量化地反映研究区景观组分空间分布，得出：研究区景观格局呈现出明显的垂直分布特征，从山谷至山顶，景观类型的分布表现为居民地及工矿用地→耕地→水域→草地→林地→未利用地的顺序，在不同的坡向、坡度上景观也呈现出有规律的分布。

| Abstract: | Based on RS and GIS technologies and landscape ecology theory,the grassland landscape patterns in Tianzhu were analyzed in terms of different landscape areas,percentage of landscape and number of patches by using Landsat-TM image in 2006.Grassland and forestland were the main landscape types and grassland was the matrix in the research area.The landscape space distribution in terms of altitude,aspect and slope was featured with remarkable vertical patterns from valley to hilltop by the sequence of residenti... |
